Water In Oil After Headgasket Change On S16.

[Mark80 0]

Hi.

 

My Friend and I have recently put an s16 into his 205. We changed the headgasket just to be safe as it would be fairly easy with the engine out the car. There was a little water in the oil before the change. However after getting the engine in and running for a few minutes it was using up the water and the oil was getting water in it again. The head nor block seemed warped but we didn't get it skimmed. A compression test comes up good/same compression on all pistons. Is there any where else that water could be entering the oil system. Does the s16 have wet liners?

 

Thanks for any info.

its a cast iron block with no liners, are you sure you put the gasket on the right way?

Yeah very sure we put the gasket on the right way, it only went on one way that all the holes line up. We then torqued it down in correct sequence.

Definately not the oil-water heat exchanger at fault?

Did you clean up the head surface properly? Sometimes they need a light skim just to get all the pitting and crap off it, that could be your problem.

Ahh, not looked at that, is that where the oil filter goes onto the block and the water circulates around it?

Well we spent a long time cleaning it to get it as smooth as possible but no we didn't get it skimmed. I know how any tiny bit of crap/gasket can stop it mating properly. Would the compression test not pick up a faulty head gasket?

yes, I had that fail on my gti6 engine a few months ago actually, filled the cooling system with orange gunk, though it didn't leave water in the oil as the oil side is running at a far higher pressure than the coolant (until you turn the engine off and there's residual pressure in the rad, luckily I had a leaky rad )

 

a compression test is simply that, a test of compression!

 

best bet would be a pressure test of the cooling system, problem is the kit to do that kind of test isn't cheap so you'd need to get it to a garage.
