BY U BOY

have you ruled ut reversion yet?
whats the cam profile?

UNSANE

have you done a leakdown test? if it passes that, then a HG might be gone between an oil and water jacket. That's what happened with me.

reversion is not a option exhaust is completly dry

My old leaky exhaust passed the pressure test, but leaked like a sieve when heated up.

But.... I'll take intake manifold gasket for 200, Alex

That is what i was told, but i filled the manifolds with water and 60 pounds of air pressure, then took 4 propane torches and laid them in each port..........Still no leaks..................gotta be intke or head gaskets eh

Just went thru this with my boat.Leak down test indicated a blown head gasket on port side.Since the intake was off told the shop to replace both gaskets.

Also,in my case but not yours, the exhaust riser gasket on starbord side was leaking too.Did you pull the plugs to see if their wet?

I'll also take the intake for $200.

nocigarette

yup plugs just wet from first run and break in.....I like to run a touch fat the first time out...Then lean my way down slowly....None of the plugs were washed clean ie reversion.......I read back to your posts before i posted this.....
