1g head vs 2g head

Ok i know the main differences between these two head but my question is are all of the oil passages and water passages the same between the two? If not this may be my my car is leaking oil or the shop just put the head gasket on wrong or something.

The oil and coolant passages are the same in regard how it mates to the block. There should be no leak on the mating surfaces unless your head is warped or the head gasket is bad.

Where is the leak coming from exactly?

 

[gsxeclipse97]

Between the head and the block in the front left corner under the exhasut manifold. and in the rear under the intake manifold.

That sounds like a bad head gasket. If there is any oil above those parts or areas, it is most likely a bad valve cover gasket.

I would check the head stud torque and if that is okay, you may need to change your head gasket and/or see if the head is warped.

yeah the head studs werent torqed down right at some of them were really loose and now the oil leak slowed down but it still leaking oil. so we figured that the oil made groves in the head gasket so it can pass through there.

 

[hopwoodp]

Most of the time, when you put a head on, you go out and drive it around and then re-check the torque. If I were you I would get a new headgasket and clean both the block and the head.

Wouldn't i need to get it resurfaced as well?

 

[hopwoodp]

Only if it is warped.

 

[gsxeclipse97]

Hmmm.. i see I didn't know that i thought whenever you take the head off you need to redo it every time

 

[hopwoodp]

Not true, it sucks because I know a small few that were under that impression. Thats why it is good to check that out when you have a bad leak. Honestly, you only really do that after some sever abuse on the motor and you overheated it.

 

[gsxeclipse97]

No i didn't over heat it but it has leaked since i got it back. the people who did the motor just did a bad job and it wouldn't even start when i got it back from them because the timing was wrong. So now its leaking oil after i got the timing redone but i have not been abusing it cause of the oil leak.

 

[hopwoodp]

It doesn't necessarily mean that, they could have machined it wrong or the surface is too ruff.
Thats why I am using a regular composite gasket instead of a MLS gasket. But, the surfaces need to be clean and the toque need to be set properly.

 

[gsxeclipse97]

That is the gasket im going to use. I was going to go with a felpro gasket and some arp head studs. Im not planning on going any higher than the evo3 16g so i don't think im going to need more than that.

 

[hopwoodp]

Sounds good. Let us know how it goes.

Side note, I think the water passages in the head were improved 92 and up heads...

 

[gsxeclipse97]

Well those aren't leaking thankfully but putting oil in and keeping it full is becoming a chore and its not cheap by any means. Not to mention the someking at stop lights is crazy.
