When you replace the crank seal, might as well do the same for cam seal since you already there; not bad, make sure you balance it out evenly when you pull the old one out; I would buy it @ toyota deal part.

SOURCE: daewoo front crank seal leak

It isn't uncommon for the cam seals to leak around that valve cover. Try using a tube of Form-A-Gasket and put a small bead around the whole cover. If that is a circular seal as I suspect and it isn't sealing up correctly then the problem is a worn cam shaft or the seal not being in place correctly.

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.

Ok ralph first off clean motor with engine brite found at any auto parts stores
next recommendation add oil base dye to motor oil allow to run for 30 min to circulate dye useing a uv lamp or black light and inspect front cover most cases the front seal is themost likely source of leaks due to contant revolutions on front main seal
in order to repar suspected seal total dissasembly of timing cover will have to be removed in some models the front main bearing journal will have to be removed as well.
upon removal of timing coverbinspect front mail seal race / face for burnishing of the crank seal face. Dirt an debri cut into the crank
you will have to order the front seal repair kit

reassemble front timing cover gaskets an sealer may be needed once all the parts are reassembled run for 15 m7n an check for leaks

Peugeot 207 1.4, small oil leak from underneath, added engine stop leak, how long before it stops leak?


oil leaks from underneath can come from front crank shaft seal --rear crank shaft seal --oil filter--sump gasket---power steering ---leaking rocker cover gaskets ---leaking oil pressure switch.--transmission seals. I suggest that you have the engine professionally cleaned and then put it on a hoist while running to see where the oil is from

The Dodge Dealer is saying the crank seal and cam seal are leaking when they went to change the oil, are these transmission seals or engine seals? do I need to place them or is there a product that will...


Crank seal could either be at the front or rear of the engine (there are two) Cam seal is at the front of the cylinder head. If the leaks are minor, a good product that may help is lucas conditioner and sealer. Larger leaks require an actual seal replacement. No sealer will work immediately. The reason most leak is because over time the seal hardens from heat. It takes a while to soften it up again.
If the leak is from the rear main seal, the transmission needs to be removed to get to it but neither seal is part of the transmission.

Oil leak in front of engine area, thinking it's a main seal


most of the time its the front crank seal, those car are known for valve cover gasket and head gasket leaks, but the front would mostlikely be the front crank seal, you will have to remove the timing belt to replace the seal. good luck hope this is helpful.

I dont know where the oil pump is on my 89 toyota


On a 22RE the oil pump is on the timing cover behind the crank pulley/harmonic balancer,it has the crank timing pointer built onto it,generally they don't leak around the pump seal but as Monster80 pointed out they leak from the front main seal wich is installed on the front of the oil pump,pretty common for the 22R/RE to leak around the timing cover gaskets or out the bolt holes on the timing cover also,usually due to uneven tourqe on the bolts,to check the front main seal you need to look at the the crank from the underside right after you've shut the motor down,if the seals bad you'll see oil starting to form a drop on the backside of the pulley or the front of the oil pump housing.
