OK, so the truck I just bought has I think some major issues, mostly lack of maintenance, but I think they're fixable. In the past, I've (a couple times) filled the crankcase full of diesel fuel and ran the engine at idle until it was up to temp with an oil pressure gauge installed to monitor pressure to ensure no damage.
On this truck, I'm considering half and half. half full of oil, half full of diesel. Run it, dump it, change filters. Run it with a cheap <$10 per jug oil, dump it and change filter again. Replace oil, install new filter, and go. This truck is a '97 Chevy 2500HD with an unknown mileage Vortec 350 in it. Compression numbers are all over the place, and the top end is full of carbon as well, which I plan to attack with seafoam. I think a majority of the problem is just stuck rings, and I'd like to attack it well now and be done with it. I figure a strong attack to the crankcase while monitoring pressure for a short period of time should do no damage to anything. Thoughts?
