I am buying a diesel (OM615) that has sat under cover for several years but ran well when it was in a car. It was removed because the body rotten tho' the drive train was good. It is now sticking.

I'd be interested in all the suggestions for what to do before attempting to unstick it.

The obvious things are:
1. Change all oil and oil filter
2. Change all fuel filters and reprime
3. Check and or change the glow plugs
4. Drain and refill the oil sump in the injection pump.

I have been advised that the only thing to do is use lot of WD40 in the cylinders after removing the injectors, and I have some doubts about that.

Others have said I MUST pull the head.

I favor adding a thin oil to every cylinder for about a week through the injector ports with a long injector-type oil can and slowly turning by hand.

Others have suggested using Rislone instead of oil, still others Ford ATF (Type F) because of its higher detergent content, compared to Dexron.

Whaddaya think?

I'm sure this thread will provide some good advice and some good discussion.

Thanks,
S (still looking for a running OM 636 for the 170DS to be)
