Blown head Gasket or ??? Your Opinions Please

[shasta]

Engine was blowing oil evrywhere but I could not find detect where the oil was originating from. Oil leaked onto both dr/pass side exhaust headers. Originally I suspected a blown head gasket so i ran a compression check and here are the results:

cylinder 1 140 cylinder 2 155
3 0 4 160
5 155 6 155

As you can see cylinder #3 reads 0. And #1 seems a little low but does not really concern me all that much. The others seem relatively okay.

There is no oil in the radiator coolant, and oil does not have the "milkshake" appearance common with blown heads.

Now I'm starting to look elsewhere and suspect other things. Possibly broken valve spring, or exhaust/intake valve, valve seals? What else could it be?

What do all you TR guru's out there think it could be?

I will not drive the car until this is resolved and will have to wait another 2 weeks until I'm finish with my finals and out of school for the semester before I can start to pull the heads off. All comments welcomed. I'll post my finding when I find the time and get a chance to to open her up.

Until then I'm curious at to what you guys think the problem is? TIA

Blown headgasket you should still have compression may be low however 0 in one cyilnder. I would pop off valve cover and check rocker arm/pushrod ETC. Also do a wet compression test, this will narrow it down for you.

When I blew #4 it had a two inch gap, so 0 or close to zero should be possible. With oil in the breathers it probably blew on the inside into the lifter valley

Let me guess it idles like crap right?

I agree with blackbuick87. The heasdgasket is done.

However he has no milk, no signs of headgasket

If it blew into the valley there would be no milk

The engine is being pressurized by the turbo, which is why oil is pouring out of the breathers

Right on the money!!!

Yeah the car does idles like crap.

I blew both headgasket once before a few years ago, but in that case there was no doubt it was a blown HG.

Thats why this time I originally assumed it was another blown HG cause it acted that way but I didn't have the symptoms (milk, oil in rad.) like I did the first time.

Now that I think about it, blowin into lifter valley makes sense, however I'm not ruling anything out jusy yet. I guess I'll definetly known when I pull the heads off.

Looks like I'll be doing my spring cleaning a little earlier than I had planned

REPLY TO "SIXAPPEAL"...

sixappeal, I had EXACTLY the same problem last september, which turned out to be the a headgasket. It was blown under the intake manifold, blowing compression inside the engine, which in turn, led to the engine spewing oil all over the place, coming out of the passenger side breather, the dipstick, etc...I'm sorry to say, that this is the answer to what you're describing!......'bye!

Had the same thing also, it was blown under the intake. I drove it home from the track like that.
