over heated warped head yeah its happened...

but even when a head over heats you can get it to run..

I don't understand, either the valves are shot and your not getting compression or the rings are shot and your not getting any compression..

the valves will have a distinct sound when cranking, and the rings can be soaked...

can you make a video, camera sitting on something about 5 feet away, hood opened.. cranking the motor.. id like to hear it

Its not quite what you asked for, but I have a couple endoscope recordings from a few days ago:


Ive already made progress in taking apart pieces to get to the valve covers (all spark plugs, coils, intake, many electrical connectors, etc) so I'm not sure its in cranking condition atm.

Finally had some time to cut off a couple stripped bolts that caused me to pause the project a couple months or so back.
Pulled off the passenger side valve cover and immediately found that the damned timing chain isnt even on the camshaft! No wonder theres no compression

Wont have time to see whats up on the passenger side today, but damn this an interesting failure mode. I have yet to see any other posts with this happening.
On the upside, there is no sludge buildup from what I can see insofar.

So I'm now at the point where I can remove the heads soon. Ive seen via TIS that you have to remove the exhaust manifold on each side to remove the heads. Any tips on doing this? Youtube is sorely lacking in certain details here

you dont have to drop the sub frame to take a head off of a m62 Or n62...

BUT you did have to take the exhaust off and drop the header out thru the bottom

Bentley page 180-23 and 24

If the timing is already removed.. and the head is still connected but the head is loose,

refasten the head bolts hand tight.. then move to the manifold bolts on the head.. loosen them.. then go down under and to the flange last...

The head is tight. I have the car on jack stands currently. So you say I dont need to lower subframe to get to exhaust manifold, just loosen the top then go in from the bottom? Sounds good.

So, some small progress:
After searching and contemplating the results for weeks, I purchased an engine from eBay: Link
Decided against trying to look into and fix the current engine as its likely toast anyway (0 psi in multiple cylinders, timing popped off driver side cams gear, broken cam lobe spring observed on passenger side, etc..who knows what the hell happened to this thing)
Engine is said to have ~100k mi

Now the question is what should I go ahead and take a crack at while I have the engine on the stand? What I have so far on my mental list:
1) Valve cover gaskets
2) Oil pan gasket, upper and lower
3) Coolant pipe
4) Valve seals

I know there are more items I may be missing. Definitely dont want to miss anything that would be easier fixed outside the engine.

Purchase the AGA hook tool since you have the engine out . It will be easier to clean the secondary air channels in the exhaust valve cavity. This is where the carbon builds up , as carbon blows out and clogs the air ports ..

Semester has FINALLY ended and I have time + a little cash

Getting ready to put the new(to me) engine on a stand. I see that the transmission bell housing mounts with M6 bolts. This seems too small imo.
Can anyone point me in the correct direction

Isn't there a secondary air delete kit available for the N62B44?

For future reference in case anyone else has this question: Found the bolts to mount the N62: a mix of M8 and M10 screws. 80mm should do it, strength rate of at least 8.8

Ill likely create a new thread for keeping track of the rebuild/install process
