I know that the tune up for the tc is adjusting the valves, has anyone done this or had it done? I ask cause mine are getting louder in the hit days, making me think they have went a bit out of spec....

FYI I know it involves changing cam buckets, so I'm just looking for if it's worth it.

valve chatter ftw!!!!
are the stock cams adjustable to change the valve settings?

I don't think so... That's why I'm looking for more info....

no they are not adjustable....if you feel they are out of spec you need to use a feeler gauge and check the cam to follower clearance...if you look in the manual (in the diy section to the right hand part of the screen) it will have the proper procedure on how to do this.

Intriguing, will check it. I assume only supplies i will need is a valve cover gasket?

And where would you guys get this done at? Stealership?

dealership can do it......or you can do it. using a feeler gauge is a piece of cake. also youll need some fpig, and maybe a new valve gasket.

dealership should know how to check...just make sure its a dealership you can trust to do this work. or do it yourself.

If you do it yourself you need a feeler gauge. If they are out of spec your gonna need new buckets. And possibly a new valve cover gasket.

If ur talking valves out of spec cant you just do a compression test?! im not sure just wondering. My car is actually in the shop right now getting all new valves. They were slightly bent but car ran fine( little chatter) i never woulda known if i hadnt taken off my header during my turbo install :/ anyhow they just did a compression test to see and i was only getting ~45 /cylinder which is BAD i guess its suposed to be 90!

Supposed to be like 190 I thought. I have a test planned soon.

Depending on how accurate the gauge you are using is, it should be around 180+. Anything less and I would investigate further.

mine was 171 ish on all my cylinders....so i say 170+ your fine....anything less THEN you investigate.

^ Some gauges have minor leaks. The one I was using was showing a constant 160. Worry wort me, used it on my roommates' near new and unmolested TC and yielded the same result. If it's near the same across the board, odds are you are OK... unless you have like 300k on it or something lol.

Hrmm weird maybe toyota uses a different one or maybe he meant to say 190 lol who knows, all i do know is he said i had super low compression!

Compression has to be over 100 psi otherwise you are not making power at all. Over 100 is when combustion really starts.
