Welcome. Im not real fimiliar with 12v but where at are they blowing out at? If it is a quick connect fitting i would say ditch it and get a good aftermarket kit. Not too many of us diesel guys on unlike some diesel only sites out there, so it may take a few days to get a good answer.

 

What does the oil pressure gauge in the dash say? (not that I trust the damn thing....) I would be tempted to put a mechanical gauge on it, and see what the pressure looks like.

 

Diesels have an oil cooler in the radiator?
