Been away from diesel trucks for a while, and I'm not very familiar with the vp44, always had a 12v. Picked up a bone stock 99 2wd auto 3500 with 376k miles. Bought it just to haul hay and pull a cattle trailer. The truck had sat for about a year and a half before I bought it, but it fired right up and I drove it home. Topped off fluids, changed oil and filters (old oil was black as sin, no dilution). Previous owner said that the injection pump had been replaced years back, and they installed an in-tank lift pump.
This past weekend I had about 15k lbs behind it between trailer and hay. When I was getting close to home the oil pressure gauge would drop to zero when I would come to a complete stop and let the truck idle, but it would return to 40 when I stood on the brakes and gave it a lot throttle. Limped it home, got to reading and the first thread on another forum led me to checking the oil dipstick. Oil was 2 inches above full, very diluted with fuel. I fired the truck up and put a temp gun on the exhaust ports, #1 and #6 were running about 50 degrees cooler than the rest.
From what I've read on here and other forums, it sounds like I've got leaking injectors. But I just wanted to ask and see if there's anything else that I should check before I throw money at a new set.
Thanks in advance
