2001 Tahoe oil leak
#61
01 chevy tahoe 5.3 4wd has a oil leak.
i have a 01 chevy tahoe with the 5.3 with 4wd. i have a really bad oil leak that iam not sure where it is coming from. it is leaking in the middle of truck right under the tranny and engine meet. i have to add about 1 qt every 2 or 3 days. the whole undercarriage from front to back is covered in oil. last time it was a bad oil pressure switch that was bad and leaked 1 qt every 2 days. when oil leak came back i checked and put another pressure switch on. but it still leaked.i think it is a rear main leak but not 100% sure.i heard it could be a oil pan gasket that is leaking. how can i find out for sure what it is. if it is a rear main seal leak i have a buddy that works at a transmission shop and will putt new one on for $350.00. but not sure what it is. if anybody can help. iam ready to get it fixed but i want it to be the right part i get put on.

Chevy Silverado 5.3 ABS and Parking Brake lights on
To resolve this issue with the ABS and Parking Brake lights coming on I pulled the ABS module of the frame under the drives side. Disconnect the two wire connections and 2 blots (no need to remove any brake lines). Undo the Torx screws and remove the top plate. There are some bad soldier joints the need to be heated up so they dried correctly (i believe there were 3 cold soldier joints that I found). I put everything back together and the lights have stayed off for 4 years now.

fuel gage going from full to empty
My fuel gage was going from full to empty, after a couple years of dealing with this my fuel pump finally went out. I replace the fuel pump and that resolved the issue. However I think it is a design issue. after 2 years with the new fuel pump, it started doing it again.

Main Seal Leak
Have the same problem with a 2004 5.3 Tahoe w/ 206k miles. I don't think it’s worth repairing (b/c it’s going to leak again). I just threw some 20w50 and bars main seal repair in it. It still leaks! The only way i’ve found the leaking will stop is to park it facing down hill.

2002 Tahoe 5.3 Infamous Oil Leak
THANKS to all who posted their input on this topic. After reading all replies, I'm going to replace intake manifold gasket, drive a few days after a thorough cleaning and decide if the leak is over. If not I'm gonna replace the valve cover gaskets and repeat. Also intending on Replacing PCV valve, and tighten some screws on the back of the block towards the firewall (guy on YouTube verified this fix so why not).
Will be back on with updates and solutions.
