Iam thinking about buying a 86 F350 6.9 diesel from a family i do work for. It is a crew cab, 8ft bed, dually, manual. They are willing to give it up to me for 300 bucks which seems like an awesome deal. Iam not familiar with diesels and this one has been sitting for about 3 years, the reason he parked it was because he wasent driving it much since he has a new powerstroke and one of the injectors was sticking. He has receipts for a new clutch and bell housing he did in it 4 years ago and hardly drove with it. What type of problems should I worry about since it has been sitting for so long? Also it doesent get too cold where i live, ussually in the winter its about 15-20 degrees, very rare for it to be below 0 and it hasent been plugged in. What kind of problems can that cause?

thanks in advance and great forum

 

Your main problem will be fluid leakage. The seal/gaskets in the motor, it will need a return line kit as the o-rings will most likely leak with a vengeance. I'd pop out the glow plugs and drop some oil in there to help free up pistons, change the fuel filter and fill the new one with ATF before installing it. Change all the other fluids as well.

My friend just woke up a 6.9 from a 7 year sit with occasional starts to move it around the property.
