Oil in the water..need help

[katLOL]

Hey guys, I just recently signed up for the forum in search of some help. I just recently built a freshly new Sr20det motor. Everything has been fine for the last 145 miles on the engine and recently my oil is being pressured into the coolant. If anyone has experienced this yet or have some better ideas the what I've looked for yet that would be wonderful and greatly appreciated. No i have not been beating the car, I'm not an idiot.

cracked / blown head gasket
cracked block, cracked head.

Do a compression test, could be the head gasket.

[jamg]

Oil getting into coolant or coolant getting into oil??

Maybe your head gasket

[katLOL]

oil into the coolant, I'm yet to read anything about it happening to anybody else. I've only seen coolant into the oil.

[OrangeVirus1]

something is CRACKED. block,head,head gasket, something is.

I'm willing to bet it has a cracked head.

[spiderlone]

are your turbo lines setup correctly?

[katLOL]

Yes turbo lines are correct its just oil cooled turbo

[Frank_Jaeger]

Time to tear it apart.

[katLOL]

Well that's great everything in it is brand new!

[OrangeVirus1]

Is the ENGINE new? block and head new? I bet they are cracked like an egg. it's unfortunate :( but Sh!t happens.

take the head off, and inspect it. even the smallest hairline crack, can cause issues like this man.


How much oil was in your coolant? a few drips or are we talking quart +?

[katLOL]

Everything was machined and pressurized before being put together. Tested out fine

[OrangeVirus1]

hmm weird.

how much Oil is in the coolant? could it be old residue maybe you used a line that had oil in it , as a coolant line?

or is it continuously getting more and more oil in the coolant. if it was machined and was good, Then prolly headgasket was installed improperly, or the block/head was warped and not decked.

[katLOL]

Block and head were decked but were talking like emptied my oil pan into the coolant

[di-devol]

Is the car smoking?

[katLOL]

Nope, not at all

[karkas9]

head gasket. no other real cause since it was pressure tested pre-assembly. take that head off and replace damn gasket.
and use arp fasteners and torque in proper sequence and rating with torque wrench.
clean the head and block with a blade.
don't use sand paper or any abrasive to clean the surface.
don't put any gasket maker on the h-gasket.

Yep, headgasket. No other way around it. Didnt get a good seal between a coolant passage and a pressurized oil galley. Oil pressure is higher than coolant pressure so when it blows its gonna be oil into the coolant. Coolant into the oil is also blow headgasket between the cylinder wall and coolant passage and/or oil drain passage which sits nearby.

Crack head or block is highly unlikely. Did you deck the oil pump when you did the build. If not and the head and block were decked you might have a lip between the oil pump and block and might be causing your sealing issue.

Either way, time to take it apart.

[OrangeVirus1]

head gasket, maybe it was installed backwards or something.

OR you hooked up the OIL feed line to the turbo onto the Coolant line.

[katLOL]

First let me say thank you to all of your thoughts and ideas I did use copper coat spray on the cosworth head gasket and arp head studs torqued in the proper sequence. I was doing some reading and another guy said that his S13 has an OEM oil cooler inside the oil filter housing anybody heard of this and has anyone ever experienced this oil in the water before thank you again

[katLOL]

Yes ash the oil pump was decked with the block and do you know if the pressurized oil galley is in fact near enough to the water galley in the head gasket for this to happen

[ashtonroche]

The likelyhood of something happening to the oil cooler built into the oil filter housing is very highly unlikely. If you want to test it, just disconnect the coolant lines from it and put a straight fitting on them, run the vehicle and see if you get oil leaking out of the coolant ports on the housing. If so then you know you have a bad unit.

And here we go again with the copper spray debate. Why the hell use copper spray on an awesome cosworth headgasket. Ugh. No need for that crap and im now definitely gonna say headgasket issue.

^This, you don't need copper spray, especially when you decked the block and resurface the head.

[OrangeVirus1]

I have never heard of issues with copper spray. although most people don't recommend it anyway.

It could be the stock oil cooler has a problem.

[ashtonroche]

Again, test the oil cooler before pulling the head. Thats the only other place besides the headgasket since you dont have coolant lines running to the turbo.

Yeah the cosworth gaskets are absolutely awesome gaskets and there is no need for copper spray. If you do it all over again, get a new Cosworth gasket and clean the head and block surfaces and install without the spray please.

[jamg]

maybe the spray made the gasket uneven and is pushing oil out of it into the coolant.

[OrangeVirus1]

the spray is like 0.0001 thick though unless you coated it like 5x. I doubt it. It's more possible that you gouged / scratched the head gasket bad when re-installing the head.

[katLOL]

Thank you all again we will begin the tear down later this week and let you all know what we find. This is kats dad the copper spray was my call so dont blame him ok :)

[katLOL]

Well guys tore it down and looked for hours and finally before we left the garage we went over the gasket one more time and a small piece of steel that was in the gasket that caused it not to seal on a oil pressure port. Atleast nothing is cracked!!

[ashtonroche]

Yep, gotta be very careful not to get metal shavings on or inbetween the layers of the gasket. Get yourself a new one and put it back together without the copper spray this time :)

[katLOL]

Thank you ash and this time no spray
