2001 Silverado 1500 Z71 4x4 oil leak

I have an oil leak and 2 mechanics told me it was the rear main seal so I had it replaced. I got home from the shop and what do you know it's still leaking oil. If it isn't the main seal does anyone have any idea what else it could be?

I had the same problem and it turned out to be the gasket on the rear main seal housing not the rear main seal.

How much crankshaft end play should there be?

Virtually none. If you have significant crankshaft end play, and you are not leaking oil, don't worry about it. If you are leaking oil from the rear main seal or from the pulley seal, consider rebuilding or replacing your engine before it seizes.
Recommendation: DRIVE IT 'TIL IT DIES. Replacement engines for your vehicle are abundant and not particularly expensive.

'91 toyota celica with oil leakage/ rear main seal

that is reasonable. considering you have to pull the engine out of car and remove transmission to do it. although the car isn't worth much more then that so I would just put some oil stop leak in and keep it toped up.

How to replace a rear main seal in a 2001 chevy 2500

several things, the rear main seal is accessable by removing the transmission. if this vehicle is standard transmission, then would recomend new clutch at this time given the amount of labor involved. if automatic, remove drive shafts, transfer case, transmission, and flexplate ....replace rear main. approx 5 hrs.

Oil pressure gage goes to o then light goes on saying low oil pressure. just had an oil change. i also have a small leak between the motor and transmission.

just because you had your oil changed dosent mean that your oil pump is working and the leak is most likley a rear main seal or an intake gasket

Rear main seal on a 2001 2500 hd gas

pull the transmission, and change the seal. Either that or you can change the PCV valve, and stop the crankcase from building up the pressure that is pushing the oil out of the rear seal.
Chnging the seal is a $1200 job, and changing the PCV costs about $15.. Take your pick. If you opt for the rear seal, and don't do the PCV.. Don't come crying to me when it is still leaking.

I have a small oil leak coming from the rear side of my engine and running down to the oil pan it only leaks about a quart every two weeks depending on home much I drive.

Could be one of two things, Valve covers leaking oil due to not sealing properly against heads, try tightening retaining bolts( do not use excessive force or you could strip or break them). Also your oil pressure sending unit could be leaking. It is at the back of the motor.

Replaced rear main seals and oil pressure sending on a 2000 z71

Check the oil filter housing and the cooler lines at the housing. The oil filter housing gaskets are good for no more than 15k to 30k miles if your lucky. The lines at the housing are easy to strip out when you reinstall them so take your time if you do it yourself an once you are finished and ready to start the truck, let it run for about 15 minutes and constantly check the area for leaks prior to road testing the vehicle.
