I have a 98 K2500 Suburban with the 454 Vortec. Recently, it developed a cold knock. Meaning, when i first crank it up, it takes a little bit for it to get oil pressure and it knocks for 30secs to a minute then clears up. Let me get a few things out of the way. Its definitely a knock without question. Today, I had a mechanical oil pressure gauge installed and tested the oil pressure after sitting all night. The mechanic said I'm actually getting 7 PSI. Now lets get to the question. What's the best way to pull the oil pan, replace the oil pump, pick up tube, main bearings, and rod bearings without pulling the motor? Yes, i know this a cheap patch and yes i know its easier to pull the motor. I work two jobs, go to college, and raise a son. So I'm broke and cant afford to rebuild or replace properly nor do i have the time to have my suburban down for an entire weekend to pull a motor. Please help! Thanks.
