Hey CRE, thanks for all of the input, I will drain the oil and coolant to see whats up with them, the compression test will be done sunday, a freinds is bringing the kit by to assist.

Well I drained the oil, no coolant in it and it no other debries or anything same with the coolant...no oil.
The coolant came out more water than coolant...must have been when I was topping it off i was mixing it too weak. Not a whole lot of coolant came out!

I got the valve covers and the gasket of course is shot...there are four bolts holding it on what do I use to remove these.

There was still alot of oil that drained so it did not lose a whole lot...

If the car would have overheated really badly why would have I lost all oil pressure and nothing but white smoke coming from the exhaust?

No worries there unless it's been a good bit below freezing temps there. Water by itself is a better heat exchanger than the components in coolant. The term "coolant" is a misnomer... it's a dielectric agent and a freeze temp modifier.

I believe it's a 10mm allen socket that you want. PROTIP: a 10mm long nut and a 10mm socket wors very well if you can't find an allen socket or they're over priced.

It could be two unrelated issues. White smoke is indicative of coolant entering the combustion chamber. A compression test may reveal it or pressurizing the coolant system may. This does not bode well for your HG though. Of course if your oil pump failed your pressure would fall to nothing and the extra friction could generate enough heat to warp things, blow the HG, causing the white smoke and crack the head allowing the gas from the combustion chamber to blow out the tensions wires.... Let's all take a moment to pray or wish or whatever it is you may do that this is not the case. This whole scenario is quite unlikely.... and a bit silly to even speculate on.

Well lets hope it's nothing too serious...
I will know more on Sunday after the compression test.
I will keep you posted?

If you're talking about the 4 bolts for the no. 3 cylinder head cover (between the valve covers), then they're 14mm hex keys. I think I paid around $10 for one of those hex keys from NAPA awhile back, they were the only people in town that had one in stock

Okay, thanks I will have to go out and get one at the local parts store.

Well, did a compression test this weekend past and was not good...didn't get any readings on #1 and 2 and about 50 on #3, and around 25 on the rest..so just going to look around for a new engine.
