Stock sleeve gsr block with manley pistons(81.5) and pauter rods and b16 head. Top mount 35r and etc.

Throttle body gasket failure, allowed water into the intake manifold and filled the cylinders. Is now running on less than 4 cylinders. When this first happened we pulled plugs, looped fast idle and cranked to get water out. Got all water out of the intake manifold. New plugs and start again, still down a cyl or two. Oil is still clean at this point. Load car up and go home. Let the car sit for a few days and now oil is milky. Also when cranking the car with rad cap off.....shooting water out of rad.

I know what i think is wrong but i hope its just head gasket and a valve or two. Im thinking its a cracked sleeve due to the now milky oil. I dont think a rod would have bent but i really dont know.


What do you guys think.? And before you say it....I know, we should have bypassed fast idle long ago and i should have had a good gasket on my throttle body, i was using an oem gasket.

 

how did water even get to your throttle body?

 

he already told you the throttle body gasket leaked from coolant port to the intake.

 

I think I ran into you at parkette. But you could have crack a sleeve or even your cylinder head could be f'ed. I am not thinking headgasket. But you never know til you tear it apart

I'm going with cracked sleeve. I had the same symptoms, hoping it was something minor, and in the end when I took the head off, the #4 sleeve was cracked. It wasn't hydrolock though, mine was detonation, so YMMV.

 

Red eg Ran a 10.7 sec 1/4. ?? Is that the car your talking about?

 

yeah.

 

I never remember the TB gasket actually seperating coolant. All it does is air passages.

So I can't see a TB Gasket causing the IM to fill up with coolant.

 

I understand the doubts as i have them myself. I am just telling you guys that you could actually see where the gasket had been allowing coolant to flow into the intake mani. Now..something could have easily broken(idle air or fast idle) and allowed the water in....but i promise this is what happened.

 

All the obd1/2 TB's i've seen keep the water passage seperate and use orings or sealed passage for the coolant. Only the crappy obd0 IM/TB's have the water passages crossac into the IM.

 

This.

 

Sounds to me like a cracked sleeve.
