My car over heated and shut off. The next I found a radiator hose busted. I replaced it. when started the car there was white smoke.I pulled my spark plugs and found them soaked in oil. Any thoughts on why my sparks plugs has oil on them?
 
Head gasket? Check for water in the oil and in any case don’t drive it, you’ll only do more harm.
 
dont have any instructions. id say if you have good knolodge and experience of engines you realy need them. if not id honestly leave the job to some one who dose as you can cause a lot.of damage with a silly mistake.
guessing you have a 4.4 v8?
 
Specialist tools needed to lock cams and time up the vanos units from what a can remember from other threads on here, if your not used to working on motor you could end up with a large lump of dead metal sitting on the drive.

There are some detailed instructions on the BMW sites as you have the bmw M62TUB44 engine, YouTube has some good videos on the timing chain and vanos procedures that will get you some of the way depending on how confident you are at spannering. It is quite involved and as said already you will need some readily available special tools.
I would try and diagnose as already said above using a either a sniff test, oil pressure test, compression and ideally leak down test.
White smoke is normally burning the antifreeze , are you losing water or is the coolant over pressuring keeping in mind these engines can be a sod to bleed the air out of?
 
Gents the Head gasket was blown on cylinder 8.I'm going to have the head rebuilt and reinstall. There was water and oil mix. Cylinders had crispy burned oil on some of them. I've performed the timing on this already.
 
Nice job , amazing how small the gap is between cylinders
Is the leak between cylinder 8 and the waterway right next to it of at the 10 o clock position, can’t really tell from the photo ?
Bore 7 ok?
There is a small non return valve in the block that can be changed while the heads are off, not sure if there is one in each block but we’ll worth changing while it is apart
 
That corner on the block is where I kept having an oil leak I couldn't find. It just kept smoking in that area. Can you explain the small non return valve issue?

What did you use (or not) to lock the cams in place prior to head removal?

The oil leak in that corner if it’s the one next to cylinder 4 is normally cam cover or the degraded pcv pipes and oil return pipes.
I’ll try and find the part number for the NRV, it is for the oil system and helps to keep oil in the cylinder head to prevent drain back. They can clog or get stuck open.
I’ll find a pic and post it for you

I believe it is 7 or 8 or both, same both sides, this is from an earlier incarnation of the M62 engine but looking at your fots, you still have them or have something there.
Have a look anyway
