Oil leak around harmonic balancer


probably the crank seal that the balancer runs against to keep the oil in the motor. you will have to pull the balancer off then pry the seal out and tap the new one into the timing cover. take a look to make sure as it could be the oil pan gasket. clean area and run car until you see oil coming out.

How do you replace front crank seal on 02 avalanche


The front crank seal is behind the oil pump on the LS series motors. There is also a seal at the crankshaft and harmonic balancer on the front timing cover. This is typical leak area. You can carefully remove the harmonic balancer with a puller, replace the timing cover seal and reinstall. Make sure not to pinch the seal lip You will have to have a special tool in order to re-install the balancer, which is extra long to squeeze it on the tapered shaft. I do not think the other crank seal is an issue since it drains to the pan behind the oil pump.

Oil leak


It is possible on these engines. If the seal becomes hardened, it can begin to wear into the harmonic balancer. It is best to replace the seal and they also sell a kit that sleeves the harmonic balancer and helps to seal any leaks. let me know if any instructions are needed.

R & r info. on front seal and crankshaft seal. Car is leaking lots of oil up to two quarts per day


Front crank shaft oil seal is located behind the crank shaft pulley (A.K.A. the harmonic balancer). If you look from under the car at the bottom pulley on the engine. It will be very wet and oily. This is not an easy job to replace the seal for the inexperienced.

Oil leak coming from "crank"


There are two main oil seal's on the crank,
1, Is behind the bottom pull, at the front of the engine. you will have disconnect the battery leads then the oil will have to be drained. After that you jack the car up and support the car with axle stand's. If the down pipe from the exhaust is directly under the engine sump? take it off.
Undo the pin's on the sump and any pipe's connected, next take the bottom pulley off.
Thats one seal.
2, You will have to take the transmission off, then the clutch and the flywheel. To get to the second one.
It will be hard. Good Luck!!
