The intelligence you have received here (mostly from a generous set of questions and explanations from member v8volvo) will not help you much until you answer all the questions. So far you have not or could not answer so are not taking advantage of the "intelligence" you value that has been presented to you here.

WE want you to succeed in restoring the performance and reliability to your rare vehicle. YOU need to do your part.

Will you please review closely v8volvo's recent posts and answer ALL the questions one by one? If you don't know, just state don't know. But try to answer ALL the questions. Before people get fatigued from repeatedly asking.

OK so got some more info. He timed the motor to the spec in the pinzgauer service manual, which is (he didn't have it front of him) +085 or 088. Does that make sense?
If the timing was 180 degrees off would the engine even run at all?

Even if the reading on the dial is correct, meaning the IP is timed correctly to the crankshaft, you still can be 180 out on the camshaft. Does he understand how that works?

We're not trying to question his competence. However, it's very common with these engines for a skilled and experienced mechanic to do a lot of excellent high quality work on mechanical reconditioning, but then get tripped up on the final steps with the timing process. What makes it tricky is that it is very specific, and demands patience and a real internalized understanding not just of the physical procedures involved, but of what they are fundamentally meant to accomplish. Those who don't try to reach that understanding are always tempted to take shortcuts on the steps, not realizing why they are so necessary. This is why the first questions we all asked were about the timing process used.

Those bare numbers look familiar but this is a specific minute range, notice the decimal: Factory specs I'm looking at shows setting range from 0.75mm - 0.90mm, depending on version. Checking timing range = 0.72mm - 0.95mm. Not sure what the + sign means.

Yes, interestingly enough, here are two recent accounts:

(starting at post #23)

NOT saying that is your problem, but the answer to your question is yes, engine can indeed run with IP 180 deg out.
