oil in coolent..

[xxkoadyxx]

Sooo I drove home one day and there was oil coming out of the overflow bottle and spilling everywhere..sooo I replaced the head gasket with a new one, cleaned the matting surfaces annd put new bolts in. I also replaced the timming belt and tensioner.

Iv flushed the coolent system out for over and hour with the car running..and oil still keeps coimg out. I drove to work and on the way back, it was blowing oil out of the bottle again..I'm lost..this is my daily soo I need it fixed. Its a 93 1.9td 400kms.

Iv asked around and had a couple people say oil cooler? What do you guys think?

I'd look there too.  Anywhere the oil and coolant are in close proximity to each other, but that would be the first place I'd check.

i would have replaced the oil cooler before the head gasket..

the coolers are known to fail, the head gaskets are NOT.

Me too, although when I had oil in the coolant, I replaced the oil cooler first--head gasket was at fault.

sometimes that IS the case, but more often than not, its the oil cooler..

i would always suspect cooler first, unless you did something to the car recently that would warrant the head gasket being compromised
(over heater, turned up the boost, whatever)

If you did that good a job of cleaning your head gasket surfaces and made sure the y were perfectly flat, then as everyone says definitely do the oil cooler.  As R.O.R. said, they are known to fail; I in fact just did one on a 03 Passat at work today.  Definitely not the first.  So go ahead and replace that, and don't forget a new oil cooler gasket when you get it.

Oh, I figured it was the head gasket. I will be buying a used oil cooler and trying that. See if that works. If soo, ill save up for a new one..just kinda broke from doing head gasket and belt -_-.. Also guys anything I should look for when doing the cooler? Ill need a new oil filter again? I just but a new bosch one in there 2 days ago with new oil.soo I'm gonna have to replace them again?

why would you have to replace your oil and filter? as long as you dont contaminate the filter, i see no reason to replace it..

all you need, when replacing the cooler, is a new seal for the cooler..

i use oil filter gaskets as oil cooler seals, FWIW..

What he sez; don't worry about the oil filter.  The oil system is way more pressurized than the cooling system, so oil only goes into the coolant and not the other way around.  And taking off the cooler will not in any way get coolant in the oil.  Just make sure the used one you get is a known good one, from a reputable source.

is there a way to pull off his old one and maybe put water pressure to the coolant lines to test it? see if water comes out the oil ports? (off the engine of course)

also, I would like to mention. yes the oil pressure is HIGHER then the coolant pressure, UNTIL YOU SHUT OFF YOUR ENGINE. at this point, hot spots on the engine normally increase pressure to as high as the cap will hold, and at the same time the oil pressure has dropped off, normally pretty rapidly too. so for the first 2-5 minutes after the engine has shut off, technically the coolant pressure is higher then the oil pressure

I have to agree with this, because when the car is running, the coolent/oil is slowly overdlowing the bottle, when I shut the car off, it sucks it back in.. Also I put 15-w40 in it cause I didn't wanna spend a lot on. Oil. Good thing I didn't cause I might have to change it..when I wipe the oil off, it wipes off into the white rag kinda gray..on the dip stick it shows its full..but not much oil seems to come off

You should be able to run tap water through the coolant sides of the oil cooler. Most houses kick the pump on at 40psi, usually above that with the pump running, and that should do it as the vw system will only show about 1/4 of that.

Soo I had the running for an hour again today, checked oil before "1/2" on the grid. Flushing and flushing and flushing. I think my rad is clogged cause water won't flow through it... Also took forever for the car to get up to temp. Got annoyed with it so shut the car off..now only a little bit of oil on the dip stick..sooo its going somewhere.I'm pretty sure into the coolent cause when I took bottom hose , oil came out. I'm gettinf pretty fit up with it..

[bajacalal]

Are you flushing it with regular water or with a detergent added?

And, if you still have a faulty oil-cooler (or head gasket) you are just going to be adding more oil to the system. Until you actually solve the problem there is no point in flushing it.

[xxkoadyxx]

I'm using just water, cause idk what is safe to use. Also iv just done the head gasket and all tq'ed down.. The only thing I can see, is the oil cooler.
