Howdy. I was having standard indications of Head Gasket failure (coolant disappearing, ethylene glycol smell in exhaust) in my 92 CX hatch (D15B8) so I pulled the head and replaced the gasket... I've done head gaskets before and went strictly by the book, so I expected no problems.

When I started it up, though, it started smoking and had exhaust gas coming out through the dipstick and filler holes (!!!!)

I figured the HG didn't seal for some reason, so the next day I bought a new one and did the whole job AGAIN... this time being extra careful and checking the head and block mating surfaces for any warp (found none).

Just finished it, and I have the same problem!... Can Anyone Help me? Ever heard of this problem before? This is my daily driver so I need to figure something out soon...

 

how does it run? you might just want to let it run for a while to see if it will burn out.

 

How about your PCV valve?

 

Ok... PCV valve was disconnected... pesky little bugger there under the intake manifold... Reconnected in and drove a few miles.

All problems remained; oil smoke in exhaust and exhaust gas exiting oil filler and dipstick holes.

Perhaps I had some ring compression failure as a result of over heating just before I did the HG job? or valve guide failure? I'm just grasping at straws here...

I'll do a compression check on each cylinder tomorrow... maybe I'll be able to isolate the problem to one cylinder then...

 

good luck

 

yea the rings could be toast too or you have a warped head.

 

might want to check for a cracked head also

 

I was actually thinking about blocked PCV, not disconnected. How was your compression test? Iftest was fine, I would check if PCV is blocked...

 

Did you get the head cut? Did you TQ down to specs? Youre using an OEM Head Gasket right? Try some ARP Head Studs, the OEM ones arent going to "Seal" as good after theyve been used, theyre really not re-useable.

 

I once had blow by after letting my car sit for 4 days. Then 4 days later it was gone and hasn't been back since.
