[Vwdiesel] running out of oil

[Kenneth E. Oldrid]

I recently swapped a 91 ecodiesel motor into my 82 westfalia vanagon. 
Things were going well until the passenger side motor mount bolts 
loosened and snapped. This poked a hole in the oil filter while I was 
going up a hill on the highway. I shut the engine off as soon as I 
could, after the oil light flickered several times. I watched the 
coolant temp the whole time, and it didn't go over the halfway mark. 
After installing a new oil filter and filling with oil, I started it 
up. It runs, but blows white smoke and makes a loud pinging or rapping 
noise.
I removed the engine from the van. A quick look unde rthe valve cover 
and things look fine. Oil and coolant did not mix, and there are no 
cracks or leaking from head hasket that I see. Could I just bent some 
valves? What should I inspect or replace? The ease of starting suggest 
the compression is still good. What tends to go first when oil runs 
out? I have access to an 89 non-turbo diesel motor, but would rather 
try and resurect this one if possible. Up until now it was in excellent 
condition and
started perfectly 1st turn with no smoke. thanks in advance for any input,
Ken
