Got a 95 k2500 6.5 just picked up on the drive home the radiator hose blew cuz of the turbo heat ran for about 2 min after over heating got it towed and replaced all the hoses and now there's about 18 lbs of oil pressure on cold start and then 0 on warm idle if I told it at 2k rpm oil pressure will stay at 17lbs any ideas what it could be (was checked with a manual gauge)
Truck starts and runs fine has 240k on it don't no if motor was ever rebuilt I am the 3rd owner
