The oil pressure was fine until my move to CO, on the way pulling a grade in Utah the oil pressure spiked and blew out the front main seal now I cab't figure out why? I thought of a rod bearing spinning, I have run this engine hard going past redline, mud, rocks everything but I have also exsessivley maintianed it with a valve job at about 35k because it was assembled with a shity head gasket. It has the stock sr5 oil pressure sender wich is electric, and the motor has about 40k on it
Now as for it being rebuilt I bought the truck with the engine in it, i know it was rebuilt because there is no way that a truck with 200k on it has no electrolisis in the head, oil leaks, new valve stem seals, rear main seal, new oil and water pump, almost no carbon build up a full seal kit, rebuilt carb now if I damaged it running it to hard and rich or the fact that you didn't rebuild the right that's fine but no one seen me coming and I just want help fixing this as i have never heard of it and I can drive the truck and it runs great until 4k rpms and the seal pops.
90-100 compression, thats not a rebuilt motor, they saw you coming I'm afraid
i always use a shotgun bore brush on oil galleys, you would be amazed at the crap that comes out even after a hot tanking
mostlikely the crank is being starved of oil and more or less your motor is slowly dieing
