Oil in the antifreeze

[Akauf587]

So the car is a 92 gsx. It has less than three thousand miles on the new head and headgasket. The problem started the other week when it sprung a leak in the oil return line. By the time the leak was spotted it lost a quart and a half of oil. Once that was fixed and the car was back on the road oil was making its way into the colant system. The oil looks brand new still, no sign of coolant anywhere. Any idea where the oil pressure would be higher than the coolant pressure???

I would guess the head gasket is leaking. Are you sure everything is torque down to specs? Do you check for warping on the head before putting it on? Any smoke out of you tail pipe?

Thats a leak, what about the torque specs? did you followed them?

 

[Akauf587]

Compression is good in every cylinder. Everything is torqued down and in spec. Moved it about 50 feet today and there was oil coming out of the exhaust. It has a good coating on the back of the car too. Would that most likely be coming from the turbo?

oil in the coolant system could be due to doing the head gasket, oil floats to the top in coolant, you could have just spilled some oil in the coolant system during the job.

look for a milky/brown condition with your oil or it being overfull. if you have a leak between the head and the block its usually coolant in the oil.

also you said you have a new head so I doubt it is warped, but did you check the block with a plane/fealer gauge?

I would flush the coolant system and see what happens if you dont see any coolant in the oil

failed turbos can cause oil burning, do you mean liquid oil or blue smoke though?

I know EXACTLY what the problem is! if the car is running fine it is NOT the head gasket. I would pull apart the oil cooler that the oil filter threads onto and presure check where the coolant flows into and out of it(be aware u will need to catch some coolant that will leak out). gauranteed someone over tightend the filter and crushed the cooling fins inside. and that is where the oil is getting into the coolant. if u need more help i can describe the procedure in more detail. But be aware to replace this oil cooler is EXPENSIVE. i bought a new housing and a 28,000 btu cooiler with oil lines for half of what the stock cooler was going to cost, and this way is soooooooooo much better than stock. Lemme know how it goes.....u can pm me if u want too. You will need a pail filled with water, and an air compressor to pressure up one of the coolant lines that flows into the cooler. plug the other end with your finger(it actually takes quite a bit of pressure to see the leak.....make note that there should be NO bubbles coming through where the filter fits onto.) Testing this cooler is very simple and requires basically no mechanical knowledge to remove and test.(in case your worried like i was).

(This would be an educated guess as to what the problem is.....symptoms are the same as mine were....and mechanics could not figure it out....cause it is hard to trouble shoot....try this test see if it is the problem,...if not im sorry for wasting your time.)

Sounds like it might be the turbo. Pull your intake and check for shaft play and look for oil in intake (after compressor). Was the return line leak at the pan or at the turbo? Maybe an obstruction in the return line. If that all checks out pull your exhaust manifold and look for oil in exhaust ports (valve stem seals).

It smokes blue and there is liquid oil in the exhaust. Did all the measurements and everything was good. Already flushed the coolant and it was nice and brown in a very short time. I only realized it had a problem when i noticed the coolant. It doesn't overheat or run any differently and the coolant system doesn't overflow.

***sorry, no oil in the exhaust. it was just a lkot of condensation. All the oil on the back of the car came from the leak. I'm gunna go check the oil cooler now, i'll let you guys know what i find. Thanks for all the help

Just saw bnpimpn's post. Here is some more info on that. http://www.vfaq.com/mods/oilcool.html

the oil cooler is fine. it was a little loose though.

My Bonneville has a rolled gasket and did the same thing... I still haven't fixed it... Maybe that could be it, but it seems like some people shot that idea down.

One thing everyone miss's when doing a head gasket is you need to clean the bolt holes for the head bolts. Material(oil, dirt, coolent) can get down inside these holes and when you start to torque it will give you a false reading.

Did you blow all the holes out with compressed air before you started to torque everything? If not I almost guarantee this is why you blew the gasket.

 

[blkdudeinaz]

it's your head those other things are plausible but you go with the thing is most recent and that's the head and head gasket I'd would suspect that your compression test came back wrong. What were the reading for your compression test? What head gasket did you use if it isn't 4 layer steel it's probably gone.

 

[blkdudeinaz]

also ditto to what jayrolla said My other car is a 944 and I've seen every style of blown head gasket and that's what you have

 

[Cs4g63]

If you can do the work yourself its only going to cost you a weekend and some gaskets. You might as well do it to make it certain that its not going to be a blown head gasket anymore. Gives you peace of mind if nothing else.

 

[JayRolla]

Yea also do not use a felpro gasket. Not sure what you used.

 

[Akauf587]

It looks like its the gasket. without the cap the fluid system belches quite a bit and builds to much pressure. Also it does have a metal headgasket. I didn't do the work myself i just rechecked the torque when i had the valve cover off to redo the gasket. I guess i'll tear it down this week and see what i find

 

[bnpimpn]

thats funny because when i started having oil in my coolant...i also had head work done...(they must have changed to oil afterwards) which REALLY through me for a loop. did you pull the assembly right appart and pressure check it? it only takes like a half hour to do it....
