1985 300d
Had a compression test done on a possible purchase. The car is VERY NICE.....spoke of $4,000, if compression was within 10% twixt cylinders AND within 20% of factory spec.
I did NOT get back to the test shop in time last friday, and only spoke on the phone briefly.
The test came back as follows: timing chain stretch 2 degrees...
#1=240, #2=370, #3=240, #4=335, #5=310
I DID NOT have time to discuss these numbers with the shop owner. This I will do on monday.
The car had the valves adjusted by this same shop aprox 3,500 miles ago.
MY QUESTION:
As evidenced by the great power and the 2 degree stretch, I believe that the car has been maintained with frequent oil changes etc.
WHY THE EXTREME DIFFERENCE IN CYLINDERS #1 and #3?
I do know that the car is driven by the wife for a 25 mile round trip for work daily and that they have very good records.
IS IT POSSIBLE THAT THE CAR HAS NOT REALLY BEEN DRIVEN HARD AND may have sticking rings????? Just a thought as I am wondering about this.
Other than the compression, MOST people would JUMP on the car very quickly.
I have NOT spoken with the owner yet. I believe that he is shocked at the compression development amd will be MOST disapointed as a result. He will PROBABLY play ignorant to this matter and just sell it to SOMEONE ELSE.
Please, lets hear some thoughts on this subject.
Best wishes always, and lets keep those diesels humming!
