3T GTE Tech

[lilcrash]

Paradise racing sell pistons and rods, just don't make my mistake and wait more then 4 weeks to ask why they haven't come. My conrods haven't come yet and it's been 7 years.

As for the exhaust gasket, 3tgtes vibrate a lot. Buy new exhaust studs and nuts and then make a brace to help support the weight of the turbo to stop it falling off.

And be sure if using aftermarket gasket, that its good quality, some aftermarket ones go too deep to the exhaust port and they will burn...

Best Exhaust Manifold Gasket for a 3T-GTE is the Toyota Genuine item, they are not expensive and work better than any of the aftermarket ones.

what aftermarket forged pistons and conrods are people using in there 3tgte? also ive replaced my exhaust gasket 3 times within the last 4 months and it keeps on leaking out after a while. any ideas why it could be doing this? ive had the manifold re-faced so its flat but still leaks.????

Is it leaking on the same spot? if so, whats the surface like in that spot?
What type of gasket are you using? the oem 3tgte gasket are good. If using aftermarket 2tg gasket, make sure it has a fire ring around the ports or you're wasting your time.
I usually go through and check nut/bolt tightness after a couple heat cycles to make sure none have worked loose.
The std manifold i've found will warp away from the head at #1. check head flange flatness although this has never been an issue for me. Definately have a brace between the turbo and the engine mount or block as the std setup has to support the weight. Also support the exhaust dump pipe to the gearbox or engine backing plate before any flexi joints because exhaust system loads will destroy the turbine gasket and possibly others.

Anyone have an old ct20 sitting around as junk? Need some bits

[AE25]

I had my 3tg seeping oil from between the head and the timing cover. so i undid the sump and all the timing cover bolts. the cover is loose but wont come off the engine, what have i missed? It seems like its stuck to something around the dummy cam

Have you backed off top chain tensioner, not being sarcastic, just checking easy to forget.

[TA22 GT]

The chain tensioner pushes against the chain guide thats bolted to the front cover. loosen or remove the tensioner and you should be fine

Is there a tab that bolts into the back side of that cover which requires the head to be off so that it can then be lifted slightly at and angle above the gear assembly before the front timing cover can be removed? I would look at this link from Stepho's website on the old 2TG since they assemble and disassemble about the same.

The cylinder head is supposed to be removed to take the timing cover off. There should be 2 x studs in the cylinder head that poke through the top of the timing cover and hold it. IF you've removed these, and it seems that you have by what you've written, the the guide (mentioned above by Simon) can still hold you up because it sits proud of the top of the timing cover (catching on the cylinder head).

Seriously though, doing this in the correct order is the only way in my opinion. Cutting the head gasket and gooping the front etc is just a 2nd rate way of doing it.

The top of the front cover has two nuts, the studs for these go into the head and need to be removed if you want to get the cover off without removing the head.

Getting it back on will be a hassle unless you remove the two dowel pins the support tthe cover., theres one on each side about half way up e cover. Without taking te dowels out i doubt you will seal the gasket properly because you need to have the cover a bit lower in the first instance.

Hope this helps...

Yep, Yellorolla is right. The best way is to remove the head. Otherwise as i said taking the dowels out is an option imo but would be a hassle to get it right..
