2AZ Engine Assembly
2AZ-FE Engine Assembly
This is a breakdown of how I assembled my engine. Not every single bolt is shown. You can use this as a guide if you want or if you need any assistance simply post in this thread. Take this guide and do what you want with it. I did not create it to get into arguments on engine assembly so do not take this thread in that direction. You have your methods I have mine. I am not responsible for what you do to your car. Parts/Supplies List WD40 Brake cleaner (2-3 cans) Paper towels (2 rolls) 30 weight non detergent oil (5qts) Valvoline 10w30 oil (5qts) Synthetic oil of your choice (5qts) 3 Toyota oil filters 90915‑10004 Drain plug gaskets 90430‑12031 Toyota camshaft housing/oil pan sealant Toyota: Oil pump gasket 15119‑28020 Toyota: Oil strainer gasket 15193‑28010 Toyota: Rear main seal 90311‑89003 Toyota: Front main seal 90311‑38089 Toyota: O-ring for shortblock (pictured) 96761-24020 Toyota: O-ring for dipstick tube 96721‑19010 Toyota: 16 valve spring seats Toyota: intake cam bearings – upper, lower Toyota: Exhaust manifold gasket Toyota: Intake manifold gasket Toyota: Throttle body gasket Toyota: O-ring for VVTI Toyota: Timing chain tensioner gasket Toyota: O-ring for Cam Position Sensor Toyota: O-ring for Crank position sensor Toyota: Oil pressure relief valve plug filter 15678‑28010 Toyota: Valve cover gasket 11213‑28021 Piston Set with rings Connecting rod set with rod bolts Main bearing set Rod bearing set Thrust washers ARP assembly lube Permatex Ultra Slick/Torco assembly lube Thread sealant Red threadlocker ARP head studs Head gasket Piston ring compressor (not the adjustable ones) Valve Seals Valve Grinding compound Valve lapping tool Tools List Complete socket set Complete wrench set 30mm 12pt deep socket (axel nuts) 12mm allen key (oil filter stud) 12pt ½ inch deep socket (head studs) 12pt 7/16 socket (rod bolts) 12pt 14mm socket (main caps) Torque wrench 3/16 allen key Magnet Torque Spec & Clearances Quick Reference Guide ARP Head Studs - 75ft-lbs final. 3 step sequence OEM Main Bolts - 30ft-lbs final. 2 step sequence ARP Rod Bolts - 25ft-lbs final + 55 degrees. 2 step sequence Main bearing clearances - Recommended .0014-.0018 Rod bearing clearances - Recommended .0015-.0020 Valve lash clearances - Intake - .007 - .011 / Exhaust - .015 - .019 Looser tolerances will be a bit more forgiving (to a point) but will also make more noise and cost a bit of power (again to a point). More power = more heat = looser tolerances. |

Shortblock Assembly
I am beginning this tutorial assuming your block is honed/machined and piston to wall clearance has already been measured. I am also assuming you have measured for your bearings already. This is just a small tutorial for assembly. I am also assuming that you have cleaned every part at least 3 times if not more – cleanliness is the most important thing. You want to use a clean paper towel and a small amount of brake cleaner on every single part and wipe it off several times until it cannot possibly get any cleaner. Your hands should be clean as well. We are starting with the bare shortblock on the engine stand and all of your parts and tools laid out neatly nearby. Attachment 60042 Attachment 60043 We are going to install our main bearings and put some ultra slick on them Attachment 60044 Attachment 60045 Attachment 60046 Crankshaft gets dropped in place Attachment 60047 Main caps get installed with the main bearings installed with some ultra slick on them They are numbered and the arrow points towards the timing chain Attachment 60048 We are ready to torque the main caps down You want to put the ND oil on the threads and the base of the bolt head Follow the sequence and torque in multiple steps according to the Toyota diagram Attachment 60049 Attachment 60050 The connecting rods need to be installed onto the pistons and the piston rings are to be installed onto the piston. Follow the diagram provided by your piston manufacturer. Install 2 pistons at a time. 1&4 then 2&3 Spray down the piston ring compressor (Wiseco 88.5 for me) and piston with WD40. *I use WD40 and NOT motor oil because your rings will take forever to seat if you use motor oil. With WD40 your engine will be broken in in about 15 minutes of driving.* Put the piston ring compressor on top of the cylinder and insert the piston and tap it down lightly into the cylinder (wooden handle of a mallet) The connecting rods should have the bearings installed with ultra slick on them. The connecting rod bolts should have ARP Moly Lube on the threads as well as the base of the bolt head Guide the connecting rod onto the crankshaft and put the cap on and hand tighten the rod bolts. Install number 1&4 then torque down the rod bolts. Spin the crankshaft and repeat procedure for cylinder 2&3. Flip the engine back over and were going to put in the head studs Put ARP Moly Lube on the threads and install the studs into the block hand tight with the allen wrench. Make sure the threads are clear of any liquids or metal shavings. The Studs should all be fairly even when installed. Attachment 60051 We are ready to put on the crankcase assembly. I do not run balance shafts and I already have the hole plugged so those steps wont be in this tutorial. Ensuring all gasket surfaces are absolutely clean I dab the Toyota sealant across the gasket surface then use my finger to distribute it around. Give it about 2 minutes to get tacky then install the crankcase onto the block. I put all the bolts in hand tight with a socket + extension then after a few minutes I start tightening them Attachment 60052 Attachment 60053 Install the oil filter stud Now install the oil pump and the 2 new gaskets and torque it down Now lets put on the oil pump chain There are 2 marks to line up – one on the oil pump one on the crankshaft. They are small dots as pictured Attachment 60054 Attachment 60055 Once the chain is on put the “tensioner” on it with the spring locked in the hole as pictured Attachment 60056 That’s it for shortblock assembly – to longblock assembly for timing … but we have to put together the cylinder head first |

Cylinder Head Assembly
Were starting with a bare cylinder head with valve guides. I am using complete stock valvetrain. *Your valves should have been lapped already to each seat* Lets install the valve seals Put a light coat of our ND oil on the inside of the valve seal. I use a magnet to grab them then push them onto the guide. It doesn’t require much force they install easily. Attachment 60038 Attachment 60039 Attachment 60040 Drop in the valve spring seats Next you are installing the valve, valve spring, retainer, keepers Doing 1 cylinder at a time Install the 4 valves with a light coat of ND oil on the stems and put something under them to keep them from moving down while compressing the spring. I use a huge ball of rags taped up. You need to have the spring with the reatainer on top with the keepers inside the retainer. You need a valve spring compressor tool. Put the tool inside the retainer where the keepers are and push them down onto the valve until they lock. It will take a few tries but you will get it Now install the cam caps. I put my ND oil around it and on top. I install them with a magnet. Attachment 60041 We will put the camshafts and cam caps on once the head is installed onto the block |

Longblock Assembly
Now we have a complete shortblock and a complete cylinder head – lets put them together. Drop on the headgasket. Make sure all of the holes match up. Attachment 60012 Drop the cylinder head on Put ARP moly lube on the threads of the stud, washer base, both sides of the nut. Torque down the nuts in sequence in several steps. These are set to 75ft lbs and I follow the Toyota sequence Picture 281 Attachment 60013 Attachment 60014 Now we are going to install the camshafts and the cam caps. Don’t forget the intake cam cap #1 has an upper and lower bearing. I put ultra slick on all of the lobes and journals All of the cam caps are numbered and point towards the timing chain Attachment 60015 We are going to torque the cam caps down – just follow the provided diagram Attachment 60016 Now lets do the timing. It looks overwhelming but its very simple when taken step by step. Make sure the crankshaft is at TDC (keyway facing up) The intake cam gear has a dot and a mark that lines up to an arrow on the #1 cam cap. The exhaust cam gear has a vertical line that lines up to an arrow on the #1 cam cap. Use the pictures provided for assistance Attachment 60017 Attachment 60018 Attachment 60019 Attachment 60020 Attachment 60021 Attachment 60022 Install the chain guides Install the crank sensor plate with the F imprint facing you We are ready for the timing chain cover. We are going to put on the sealant in a similar fashion as the crankcase. Attachment 60023 Now install the crank pulley. Use this to ensure your at TDC (its notched) and double check your timing. Now install the tensioner all the way in with the hook set. Once its installed use a coat hanger or welding rod to release the hook. Turn the crankshaft counter clockwise slightly then clockwise and you should hear the tensioner click and the chain should now be tensioned. Attachment 60024 Attachment 60025 Now lets get the oil pan and install it. It installs with the Toyota sealant just like the crankcase and timing cover. These are very small bolts be careful not to overtighten and snap any of them. Attachment 60026 Install the water pump Attachment 60027 Install tensioner pulley Attachment 60028 *I do not run A/C or Power Steering or there pulleys* Those two pulleys and the belt are up to you because my setup is custom no sense in posting it. Install the valve cover Attachment 60029 Attachment 60030 There are probably small odds and ends I skipped but common sense should help you here. If you have anything left it most likely goes somewhere. Congratulations – your longblock is assembled. You are now ready to put on the transmission and install into the car. I will post some pictures from here out maybe they will be helpful to you. Once the block is off the stand install the rear main seal. I lubricate it slightly and it should sit flush with the block Flywheel/Clutch Attachment 60031 Transmission Attachment 60032 Dropped in on the engine mounts Attachment 60033 Attachment 60034 Attachment 60035 Attachment 60036 Attachment 60037 |
Initial Startup/Engine Break-in Procedure (my method)
MY Engine break in procedure and initial startup procedure. This is not a thread to dispute engine break in methods. This is what I do and it works so im sharing it. Make sure all of your fluids are in and there aren’t any leaks at this point and everything is at their proper levels. All of your bolts are tight, etc – Common sense check. Fill the engine with Non detergent 30 weight oil to its correct level (about 4 qts) Our engine is in and ready to go. We are going to remove the spark plugs and unplug the ECU. Crank the engine over for 20 seconds 3 different times. We are building oil pressure here and checking for leaks. You can also verify your timing again if you want. While cranking keep an eye on the oil pressure light on your dash. Make sure it goes out. Again – keeping an eye out for leaks (friends are useful here). Now you can install your spark plugs and plug in the ECU. Hopefully you have your laptop connected to your ECU and can make Air/Fuel adjustments for startup – this is up to you. Crank the engine and fire it up. Keep an eye out for leaks again. Give it some throttle here and there while maintaining a proper AFR. Check for leaks/anything odd. Get it to operating temperature make sure the fan kicks on. Were going to keep the car on for about 10-15 minutes. Shut it down – fix any leaks or anything. Let it cool for several hours. Drain the non detergent oil and remove the oil filter. Inspect both carefully. There should be metallic flakes. Ensure there are no chunks of well... anything but especially metal. Put in your convential Valvoline 10w30 and a new Toyota oil filter. You are going to be using this oil for about 100 miles. For engine break in you want to do a lot of varying throttle up to about 60-70%. You are going to want to do a lot of engine braking – down hills is good. Drain the valvoline oil and remove the oil filter and inspect both carefully. Put in your favorite synthetic oil and a new oil filter and enjoy your car |
Great write up
Sent From My Evo |
wow! this write up is awesome! props to you for taking your time on doing this for SL
|
amazing.
|
Nice work!!!!!!...man you got time on your hands for sure...lol
I guess you didnt get those sleeves, oh well. good luck on your project! |
I can use this like a checklist, im in the process of pulling the motor right now! nice post!
|
I think im going to add a full gasket/oring list and you can get what you think you need
|
|
Good point
I wanted this to be after the cylinder hone and bearing clearances were done.. just wanted to do assembly |
Seems we are in the same stage of our projects! I got new cams and need the head work to be done though >_<
|
Great DIY, good luck on your project. Also can u pm me a price on putting a engine together.
|
you can has sticky

This is awesome, is the short break in due to the wd40? If so when I build mine that would make things much easier!
|
Yes. I never use motor oil on the piston, rings, cylinder walls.
|
quick question torquing the headstuds, after torquing to 75 did you have to do another 90 degree turn?
