Celica Bt4 Gasket Exhaust

[Gsc]

Hello, I recently put a new head off a mr2 turbo and the egr valve would not fit so I was told it was ok to remove it, the exhaust manifold is sligthly different but firs but I have air getting in and wondered if the exhaust gasket should be diffierent now I have removed the egr valve, can you help please, car is running rough at the minute due to the exhaust gasket leaking

have you blocked off the hole in the head left by the egr pipe ?

if not make up a plate to block it off

Yes I did that, I bloked it off, do I need different gasket or not?... could the leak at the manifold cause my problems?

the leak at the manifold could be causing it, there are only two differant stud patterns for the 3S-GTE head so there's only two differant gaskets

well 3 if you include the ST-165. a pic of the manifold on the engine would help. also point out where the exhaust is blowing.

the manifold studs have a habit of pulling and the manifolds them selves warp so it could be either of these but a leaking exhaust will affect running as it screws up the lambda reading seen at the ECU

So it seems the exhaust manifold gaskett is not a problem but the blowing at the exhaust is>>? should i sort this out first then report back?
