Need help or opinions !! I've a good stream of water coming out the exhaust pipe after changing a head gasket and intake gasket. I've read the posts on leaking intake gaskets but mine is really a major leak and I've changed both the head gasket and intake gaskets twice. Not my first rodeo, however at 70yr old, I might have lost my touch. It almost seems as though there is a passage I'm not catching.
data: 93 4.3L vortec / repaired a broken rocker post / no leaks before the rocker arm problem / head check for true / used felpro gasket set and reassembled / major water leak into cly and thru the exhaust system / stream out the pipe with billows of white smoke / water in oil / NO oil in water /
tore it apart used better gasket set and it produced the same results !
Tore the upper and lower manifolds off bought better gaskets clean the devil out of it reassembled and it's doing the same thing. Water out the exhaust / water in cyl / billows of white exhaust smoke.
I could use some help / I must be missing something. Any ideas?? Thanks BC1

 

My only suggestion is that your putting it on backwards.

My brother-in-law's car was leaking oil from the head gasket and it turned out he had it upside down and the gasket wasnt covering an oil passage.

 

or a cracked block? check your cylinder walls when/if you tear back into it. depending on where it is in the stroke it can leak into the block or cylinder


or it could be bypassing the rings to enter the block if the leak is major enough.

cracked head?

pitted or warped?(including block)


just some idea's. i personally have never had to do a head gasket

check your plugs and you might be able to tell what cylinder it's comming from.

 

any follow up to your problem? I have my heads removed right now from a 4.3. I have felpro gaskets and the only thing i noticed was the rear water port should be covered by the gaskets on both sides of the intake manifold.
