Coolant in oil and vice versa

[tenaciousd199]

So the car has been sitting for about 3-4 years now. It is a 99 GST, when I got it I fixed everything I came across. I fired the car up, and there is steam coming from the exhaust mani and out of the exhaust. I figured it was just start up smoke from sitting. The car died, which I think may be from the battery being low and the alt not charging it at idle or something. Battery is at 11.43 volts right now when cars off. I pulled the dipstick and it was WHITE (had straight water in coolant with some flush). Pulled thermostat housing cap when it was cool, and there was some oil in there. I pulled the plugs, and the #1 had some of the oily mix in it, same with #2 but it had steam coming from it. What do you think it is? I hope it is not a headgasket, the car is damn near stock and only has 36k miles on it. Thanks

Also, when looking by the oil filter housing, it appears to have oil or water sprayed around and getting onto the exhaust. The filter was on tight but I don't think I put it on too tight, could it be the cooler anyways?

head gasket or cracked head

If you got chocolate in your peanutbutter the head must come off. Take a sniff of the radiator or overflow tank. It will smell odd if blown into the combustion or fire ring of the headgasket. Cracked exhaust seats will just give you steamy exhaust and coolant odor. It might be an easy fix. Tres...

the oil filter housing is certainly worth a closer look. that would cause the symptoms you describe; as would a head gasket failure. however, white smoke from the exhaust is usually burning coolant, where as blue smoke is burning oil. if youre blowing white smoke, then the head gasket is the most likely culprit.

idk what it is coming out of the exhaust. The guy I bought the car from said he did a compression test before I bought it and it was good. I didnt check the compression myself though.

I'll start with the oil filter housing. there is a comin thing with these cars(seven bolt and 420a) The oil filter housing has a large bolt that goes through the cooling cylinder then into the housing. that bolt is comin to come loose and or push the large o-ring out that sits in between the cooling cylinder and housing. I would check that by grabing the oil filter and trying to shake it. if it does not shake then look around that cooling cylinder and see if you can fine the ring popped out. If not play it safe, pull the filter off then pull that bolt out and check that o- ring.

the head gasket is most likely the reason why you have all that oil on the plugs and water in the oil. there is also oil in the water so you most likely have a bad gasket. you may have a warped head and those are the only two real reasons why you have these symptoms. Either way, the head has to come off. Another thing you might want to look at is once the oil is drained, pull the oil pan off and check for metal shards and what not. It's so much better to play it smart and do that then do all this work and find out you have a spun bearing from having all that water in the oil.

supplies are easy to get and some what cheap unless that head is warped. if you have a bad o-ring in that oil filter housing then i dont know about your area but i know when i blew that ring to shreds and tried to find another one, i had to have it imported cause i couldnt find one.

The previous posts were from me on my friends acounts... so there is no possible way it could be the oil cooler? I will pull the head but i REALLY do not want to do it. Would it really be a bad headgasket on a stock 36k mile car?

ive seeen shit happen around the same time so i would just check everything. the oil cooler would be the first just get under the car and grab the oil filter and try to shake it.. if it does not shake check the o ring and then go from there

Excellent advice about the oil cooler dsm'r sk1mp. That's where I would start. I would recommend removing the oil filter and checking the spline manually. Oddly enough, the other day when I was changing my oil, my spline was loose. I didn't know until I actually pulled the filter.
