Ok so i finaly got my head back after $615 to do the valves. I get it allback togethor and it runs, not the best running issues. There was white smoke pouring out of my exhaust. I let it heat up and the smoke dissapeared. I then tried to restart it. Nothing it sputter starts never get over 1,000 rpms and dies out. I did check engine light test and this is what i get. 1263 Purge Valve This code is stored if there is a break or short-circuit at:
Evaporative control valve, wire from the DME control unit or
the output stage of the DME control unit is defective (M1.3
only). I did a compression test and got nothing in piston 1 and 2 got 60 psi in 3 and nothing in 4. I did a compression check in all 4 cylenders before i fired it up and it was fine. Plus my car shook like crazy when i first started it but it died down. Any suggestions?

is it timed correctly? Meaning, when you reinstalled the head, did you make sure to correctly position the timing sprockets, cams, etc?

Did you also drain out all of the old oil & coolant and put new oil & coolant back into the engine?

Did you install all new gaskets?

Did you ever check to make sure the engine deck (top of block) was 100% square and was not warped prior to reinstalling the head?

white smoke, sounds like coolant blowing out the tailpipe...

Yeah i checked everything. It started right up this morning and got warm and then died at normal operating temp. I keep getting that code 1263. I am going to mess with the o2 sensor and a couple other things today.

the o2 sensor wont solve your problem thats for sure.
white smoke is a bad sign but it could be only that some water was evaporating from the exhaust. since your car has been sitting for a little while. right?

Yeah antifreeze leaked into my head a little on the dismantle. Man i have done everything to get this thing running nothing is working. I am just probably going to have the bmw dealer come get it and take a look at it.

Drop the tools and step away from the car.

Sounds like coolant in the cylinders (white smoke, shaking crazy) and you bent your rods (no compression)

If you read the Bentley Service Manual, followed directions and put it together clean and correctly none of the above would have happened. What a waste of time and money, shame.
Its done. No compression is no compression.

Your going to get ass raped at the dealer, you know that right?

Might as well cut your loses and just sell the car at this point.

Ok well i am going to pull the head and re-do it. I am using a haynes manual. Where can i get a bently manual?

It seems like alot of people here are harsh. But it's cool i am used to it i am in the army. I am going to rip it apart and start over. If at first you fail try again... and again.. and again. One thing i forgot to mentio is tht they plained my head should i get a thicker gasket? Maybe my gasket is 2 thin?

Well, you have a good attitude. I can respect that. Lessons learned--follow instructions and double-check your work?

How much did they mill your head? More than likely not enough to warrant the thicker stock gasket.

That is a good attitude. I was a little harsh and I apologize.

I am assuming your fairly new to in-depth engine repairs. Too be honest the M42 is a pretty complex and technical engine. Certainly not the first engine I would want to learn on.

Cleanliness is critical to proper engine assembly.

When you get your cylinder head off, clean the surface and take a detailed picture. Its possible they took too much material off the head and the front profile gasket maybe keeping the head from completely seating on the block. I believe the max amount of material that can be safely taken off the head is .015". Also its very important to have the front chain cover bolted to the front of the head as it needs to be surfaced with the head.

Post back when you get it apart and hope the second time around goes better for you.

Also where are you located?

Post pics man. Post pics of each step if you can.
Hope it's a matter of timing a little off. Don't want to make any predictions on it though. You've done the work before, it'll be easy this time. I really hope it isn't catastrophic.
I've got more valves I'll take out of the spare head if you need them, just let me know.
