well, no... i don't want to do it if I don't have to. But, I can't afford too much down time and I also can't afford to pay someone to fix it (and it's also a matter of principle, heh)... I haven't bought any replacement parts or rented any tools yet, but I did want to know how bad it could get money-wise so I had an idea.

It could be a clogged radiator or a bunch of other stuff, especially since the compression appeared decent across the board to me (@ 200 to 220 psi per cylinder).

That, and the temp gauge only hit "H" once after a cold start at 9F after like 10 minutes... It doesn't add up.

holy smokes man, pelican gave you all the parts for a head gasket change, valve cover change, CCV change, entier cooling system overhaul, etc etc etc. jesus. that's a little excessive if you ask me.

you don't need the Bentley manual, I have one, paid $70 for it and have used it like twice over the past 5 years. 99% of the DIY's i've done have come from the wonderful pictorials on this site...

Oh, and if I want to run quick tests on the car, can i run it without that PCV hose (since it broke)?? On my Hondas, it's no big deal, but I figured I'd ask someone more experienced w/ BMWs.

My current plan once I'm back near the car is:

1. Drain coolant completely
2. Re-bleed w/ Deionized water until what comes out is clear and then use BMW coolant / DI water mix - 50/50
3. Change spark plugs & replace PCV hose if necessary
4. Reinstall coil packs and run it - monitor water temp gauge and smoke scent / quantity as the car warms up
5. Note symptoms -> temp gauge on "H" & smoking after warm up period & coolant level after it cools back down

If temp gauge reads H, but no smoking, or coolant loss, replace water temp sensor
If coolant loss, but no H or smoking, check for leaks (i'll be doing this anyway)

Do you guys agree that with my compression test results, a bad head gasket is NOT the issue here?

thanks for the info. i have no problem saving the cash instead of buying that manual... Pelican also does have decent DIYs as well. It's just a matter of taking the time to get familiar with the different techniques used.

If you run the car with no PCV hose, that would cause a massive beyond words vacuum leak most likely. Thats like having a cracked intake manifold.

Just because your car went to H once and the car smokes a little in 9 degree weather, doesnt mean you have a blown head gasket. Condensation will cause all cars to smoke in cold weather like that. Now, if your filling the whole street with huge clouds of smoke, then you have a problem.

Do you have coolant loss or do you not? I don't get it.

After the car was smoking, I checked the coolant level in the expansion tank and the indicator was still at full. Is there any way the indicator could still read full and also lose coolant in the process (like a clog somewhere)??

Well if the indicator reads full, why do you think your losing coolant? Clogs are usually in the radiator, and that might be why you overheated. Also the thermostat being stuck closed could do that. I think you jumped on this head gasket thing way too quick.

Well, because of the smoking thing... I guess I really need to do those tests I outlined and confirm the smoke content.

U can do a Pcv/ccv delete and see if that fixes ur problem....If if was ur head gasket u would know. Did I get ur Tests back on the oil? If the indicator is full then most likely ur coolant is full, check ur radiator; if the car overheated once in 9f after 10 min that doesn't sound right. Check ur entire cooling system, if that's fine then u can rule that out and work on hg but it's very important, especially when working on cars urself, to check EVERY POSSIBLITY, it sounds like there is something in your cooling sys.

Is there a way to "check" the radiator at home? What is a good way to confirm it is not clogged?

If temp gauge reads H, but no smoking, or coolant loss, replace water temp sensor
If coolant loss, but no H or smoking, check for leaks (i'll be doing this anyway)

I guess I could add to the above if symptoms persist:

6. Drain coolant again
7. Inspect radiator (replace if necessary)
8. Inspect waterpump (replace if necessary)
9. Inspect thermostat (replace if necessary)
10. Inspect expansion tank (replace if necessary)
11. Replace hoses involved with these assemblies

Also, concerning the condensation issue... Are you guys generally saying that the milky residue goes away by itself once the car reaches operating temperature?? If so, that could be another check.

Not to my knowledge. You know it's clogged for sure when your driving down the highway and the damn thing still overheats at -0 temps. Thats why Im replacing mine. Also when you go to drain it, it should be pretty constipated. I could get no more then half a quart out of mine.

Milky residue!? Why is this the first time we're hearing about this? Where do you see this milky residue?

Ah... because it's on the video I shot that never got uploaded.... But yeah, when the PCV hose broke off, there was some greenish/brownish sludge as well as on the underside of the oil cap. I was in the process of pulling off the valve cover to see how much was under there and compare it to the pictures of carnage from other head gasket failure pics/threads...

Greenish/brownish doesnt sound bad. Light milky colored mixed with brown is a different story. That is oil mixing with coolant.

Take some pics for us.

You don't wanna know. It will clog your radiator up so quick, that you won't have a chance to ask "why did it clog up my radiator?" Plus it only worked for like 2 weeks for me. Then the leak came back. Except I need a new radiator now.
