Do you know whether not they actually did it oil pressure test? Is the engine making any unusual noises?Skyvisions
If you do not have any oil pressure the engine should belocking up or making noise. If they put an actual oil pressure gauge on thisand it shows zero the engine probably is no good. At this point you're probablygoing to be better off trying to find a used engine. This will more than likelybe your cheapest route. Unfortunately I do not know anybody in that area thecountry that can give you assistance. Your only other possibility would be totry a new oil pump and save the engine that you have.
