Ok so for the last while my car has been hard starting 500k on new motor. Rebuilt top to bottom new pistons valves gaskets waterpump etc car has been cranking but then spitting and kicking and finally turing over smoking white for 5-10 then clears up runs great so i pull the plugs. And they all have coolant on them so i decided to crank the motor over with them out and bam coolant shooting out of every hole whice if it was a headgasket is very unlikley to be every cylinder so now i pulled the supercharger and manifold and there was no coolant sitting in the manifold but very distinctfuly coolant was visible behind the valves and in the intake port in all 4 ports so am i crazy or is it possible the laminova orings are leaking causing this i never changed them with the new motor but i think the machine shop put the intake manifold threw the parts washer withought taking it apart .any ideas would be great ..

Thanks Kyle

you either have a bad o-ring or bad core you can get new o-rings from zzp or C.E.D.

I am pretty sure Powell has a bunch of them as well if you don't want to bother calling with shipping from the us

I had a problem with coolant leaking past my laminova O-rings, picked up a set from ZZP to replace them.

Ok so i just replaced the laminova orings poured out the milky oil all new coolant started up fine smoked for a sec like before and missed for a sec (as to be expected with residual coolant in cylinders ) started up again 10 min later no miss no smoke now im just going to wait till tom and see if it hard starts when cold ..

So its still doing the same thing going to do a coolant pressure test tom see where its going hopefully my new motor wasnt put together incorectly. Only thing i can think of is machine shop used a 2.2 headgasket..

Just pressurized my cooling system (engine side ) and it held pressure just fine put it too 14 psi and it would bleed off less the a half psi within 10 min so i guessing thats normal the only thing is is the kit i bought wont fit the supercharger side for testing anyone know where i can buy an adapter ?
