Coolant in oil = BHG or cracked block/head. A compression test won't always show a BHG but the facts speak for themselves.

^ya and 99% your head gasket is blown or a cracked head. either way replace hg and get the head checked out. if you want to test it some more get a block test done as grimreaper said

As poodles said "DO NOT DRIVE IT!"

There are three ways to blow a head gasket.
1) Coolant in cylinder
2) Oil in cylinder
3) Coolant and oil mix

You may or may not have a BHG but you definitely have a problem.

You could have a cracked block as others said. Or your block could have actually rusted out internally. My dad used to have a 22RE pickup, and he didnt change the coolant often enough. Long story short the wall between the coolant and oil passages rusted out, of course the mechanic replaced the head gasket w/o realizing this wasting time and money. Also possible is a cracked cylinder head.

Fully built 7m, had coolant in the oil and the motor only lasted 1500k.
Stop driving it as mentioned, and do a leak down test.

What kind of gasket is on it?

ok i dont have a leak down tester/block tester, but i did check the o2 sensor and it was all white and when i pulled the spark plugs #1 and #2 were covered in oil. these are usually signs of a blown headgasket right?

im not really sure what kind of headgasket it has right now but its probably just the stock one. i already started pulling everything off to get the head out so i should know soon.

Well now you have a little of an idea of what is the problem. I blew my head gasket, and you would think you would have more coolant in the cylinders, well like you, I had oil in the cylinders. I took a cue tip with an wood kabob stick and went to each cylinder. I had more oil in there, but also coolant. I am sure you blew a head gasket.

Remember though, once everything is torn apart, have a shop inspect it, the worst thing you could do is tear it apart, and then put it back together and still have issues.

Also when my HG blew I am not sure if it was before I owned the car ( I had it blow up on me the night I bought it ) 62-1 full 3" blitz, HKD FCD ( Pile of shit ) Blitz filter, cooleeze DP, coolze intake, stuff like that and it blew a compression ring the 2nd one.. I have no idea how, or why.. it may have been like that when i bough it, but yeah check everything.

Not to mention you can eat your bearings as well... with that coolant.

well you COULD eat the but they wouldnt taste too good... metal with coolant and oil just doesnt taste as good as a good southern fried chicken, ya know?

dont worry i haven't driven it since i first thought it might have a bhg.

i would have known for sure today but 3 of the head bolts striped out on me so know i need to figure out how to get those loose.

you deffinetly have symptoms of BHG, However, about a month ago my 60-1 ct turbo went bad and i had all the signs of BHG from the bad turbo. I had coolant in my oil, car was over heating, fouling spark plugs. Turned out to be just the turbo was shot. Just an idea for you to keep in mind. Also my compression was perfect all the way accross to.

What were your compression numbers?

Thing is Teal, Nate is not posting nonsense...in fact, what he pointed out was the opposite is true. At the risk of becoming a power hungry mod (in your eyes), you might want to consider posting less and thinking more before you do.

What i posted makes just as much sense as everyone else saying they had the same symptoms when they had BHG.

No one knows right now what the problem is, my theory of a bad turbo is just as likely as eveyone elses theory of BHG. Seeing how he has the exact same symptoms I did PLUS good compression, gives me reason to believe it could be the turbo.


Some how my turbo was blowing coolant and oil into the cylinders and it was fouling out some of the plugs. When i pulled my plugs i could see coolant in the cylinders. I thought for sure i had BHG, when in fact I didn't.

At any rate i'll take your pennies anyway :p

My "non-sense" is your ignorance.

And incase you haven't been following I actualy have been doing some good. Building a supra right and giving a good reputation to Mkiii supra owners out on the street.

Im not saying that his turbo IS bad, im simply throwing out an idea. Granted, if he has a stock head gasket he should replace it anyway. But BHG isn't always the answer. I hated when I had all these symptoms everyone was jumping down my throat telling me I had BHG when infact I didn't.

And what are the chances of his compression being fine if he has BHG? Seriously. He stated there is coolant and oil getting into the cylinders. IF he has BHG that means coolant is leaking into the cylinders from the head gasket. IF he did a compression test the compressed air would be leaking back out where the coolant and oil were leaking in. Meaning his compression would not be fine. Does that not make sense??

To make things more clear it would be nice to know exactly what the compression numbers where for each cylinder.
