leaking front mail seal.....cheap fix? how hard?

i noticed a drop or two or oil from my front crank seal each time i park my truck after running it for awhile.never more than a few drops. this JUST started. the motor only has 30k on it, but i dont exactly trust the expertice of the shop who did the rebuild, its a good motor and uses NOT oil inbetween changes. do i need to replace the seal? or put in a bottle of "stop leak"? or leave it? BTW its a 22re. thanks

Easy fix. Go to the part store and buy a new seal with the pulley repair sleave. I think its like $13. It will take you a whole 30 min to change if your slow. Good luck. Let me know if you have any more ?'s

I wouldn't put stop leak in my motor...

The Front Main Seal shouldn't be that bad. Little farther in then a timing chain swap. Figure half to three-quarters of a day for your first time. I can't think of anything that even requires any funky tools. Getting the crank pulley bolt off is the hardest part I think... and if you use a big wrench against the frame rail and pop the starter it should loosen it right up.

Check the timing cover to make sure there is no excessive wear against the water passages and have a good look at the oil pump while you are in there (although it should be new if it is a rebuild).

I know there are a couple write ups on tchain swaps out there.

It's been awhile but I thought it was behind the timing chain cover?

Nah...

The T/C cover doesn't have to come off, you must be thinking of the 3.0 L V6.

Mine also recently started leaking, just enough to keep things rust-proofed, so I might ignore it for awhile, unless it gets worse. But if I was gonna do it, I would drain the coolant, and pull the radiator, to make it easier to get all the belts off. I know you don't have to do this, but I always prefer to take a few more minutes to get crap outta the way. Besides, it's a good chance to hose all the mud out of your radiator fins. You might need a puller to get the crank pulley off, but not always.

I changed mine when I did my timing chain over a year ago... so I am probably wrong...

Last time I replace the front main seal it took me an hour, with lunch in the middle. Not hard at all. Easier to replace the seal with the oil pump off, but not necessary. There is an o-ring behind the oil pump that also leaks sometimes.

I just replaced mine in a 22r a couple months ago. Bought the seal for like $11 almost a year ago and for some dumbass reason thought it would be difficult, then finally did it one morning with a hangover. Super easy, super cheap, felt stupid for waiting so long.

Oh yeah- put it in gear w/ the parking brake on and the pulley bolt comes right out.
