Hello all I am new to scions I recently bought an 09 scion tc from an insurance auction for my girl friend. One of the things that was broke in the wreak was the timing cover where it mounts to the car so I went to a local junk yard got one for $75 and took mine off when I follow the instructions on setting the timing gears to tdc according to alldatadiy the chain has alot of slack between the gears with both on the yellow chain and timing marks set tdc bottom is also set the way they say to in the diagram the chain should be tight when the gears are set at least between them and then you would put the cover on and rotate the crankshaft counter clockwise and release the plunger well I did that twice now and both times the chain has slipped on the bottom gear what am I doing wrong Please help me on this I also can look some stuff up on my subscription for anyone who might have a question I could find the answer to thanks

 

Can you please fix that diary of a run on sentence so we can accurately see what you are trying to say?

 

Okay I will try and explain this better sorry for not being clear!

I bought the car as a builder car for my girlfriend and one of the things that needed to be fixed was the timing cover.

The timing cover was broke so I needed to replace it so I picked one up at a junk yard!

I then set the engine to top dead center with bottom pulley and the two camshafts at tdc!

Removed everything according to alldatadiy.com got my new timing cover cleaned up took all the seal packing off (aka) toyota fipg sealant applied new and set aside

I then noticed that the two cam shafts with chain on them seemed to be in the right location but the chain was sagging between them when I tried to align the marks better thinking they had moved they would push back so I figured they had to be lined up!

LINED UP MEANING there is two yellow chain links lined up on the camshafts and one pink chain link lined up on the crank everything tdc!

I then put the cover on tightened all the bolts to spec and bolted in the chain tensioner with hook reset which as all of you know I am sure is a plunger style with a hook!

I then followed the service manual telling me to turn the crankshaft counter clock wise and release the plunger! I did and I have done this twice now and each time the chain slips when I turn it to the left!

Whats going on here someone has to know?

Why are the camshafts allowing the chain to sag?

Am I missing some trick or step?

Thanks for looking and please give me a hand on this someone has to have a logical answer to this!

Also if you need a wiring diagrams for a 2009 scion tc I have them all! thanks

This will walk you through and ignore him because he cant read! lol



Its a repair manual of the 2azfe engine and will help you much better, and you can download and keep for future projects on the car.

 

You prob are using the wrong timing mark on the exhaust cam. Its the one that doesnt have an I or E, its jsut a hash. Sooo many people have gotten timing wrong because of this.

Also, there will be slack in the chain untl you release the tensioner which is installed after the timing chain cover, make sure you have the timing/links lined up beforehand.

Once everything is timed, the cover is back on, and you release the tensioner, turn the engine over twice (thatll go through all four strokes for all pistons) than check timing - when the pulley is at 0* mark the marks on the cams should line up with the mark on the 1st cap on ea cam. Hope this helps.
