Front main seal leaking??

    Well I think my front main seal is leaking. The bottom of my engine is covered in oil and it only happens when the truck is running. Never once have it left a spot of oil on the ground. Nor is it bad enough to make the level drop on the dip stick (which I check weekly after discovering this). The leak appears to be coming from the front main seal as opposed to an of the oil lines. I have yet to pull off the crank pulley and check under that.


    I was just wondering if anyone else has ever heard of this problem??

    Not nearly that bad.. I just have a light film of oil that occassionally forms a drop if I dont clean it off for more than a week.

    I was looking around on here, it seems like the timing cover is a place known to develop leaks

    I just have a light film basically everywhere but it seems to start around the front main/crank seal, so thats my best guess for now

    i had my front timing cover seal start leaking. It would leak at the bottom left corner very light then it got a little bad over time. Dealer wanted $1500 to fix it i bought oem toyota parts and fixed it for $90.

    I replaced my front engine oil seal (crank seal) myself about 2 months ago. The seal was around $20 and can be done in a few hours. I made a pulley holder from a piece of flat stock. Tried using the ratchet strap/chain to the frame method without luck. Loosened the bolt by bumping the starter with the breaker bar against the frame.

    I forgot about this thread.. well they replaced the main seal and reinstalled my stock pulley.

    Ans then the leak started again... turns out the stock pulley wasn't creating a good seal either and it needs to be replaced too. Good news is that the dealer is replacing the seal again without charging me any labor. I only have to pay for the new pulley ($300 but it could be worse)
