front seal on the crank. behind the balancer.get some brake cleaner wipe down real good than start it up and let it warm up and crawl under and see if you can tell where its coming from.

I see it dripping from the front seal. I changed the gasket once. Could it be more than just the gasket?

the seal goes in the timing cover. it also could be where the rubber part on the front where it meets the cork on the pan. i always put a dab of gasket sealer on the corners along with under and on top of the rubber. but if its the seal than you need to pull the balancer off and get a new crank seal. if the oil is above the pan that would tell me its the crank seal.

To start drain and remove the radiator, remove the belts, the crank pulley, and then the balancer. You will need a tool to pull the balancer, there is a bolt in the center that you have to remove. After the balancer is removed you can then remove the seal, it's best that you use a tool for this also. after you have removed the old seal clean the area, and you are ready to install the new seal. There is a tool for this. I have used a large socket in a pinch but you run the risk of getting the seal in crooked. This is a shortened version on how to do this, it's not that hard, just take your time. Install is the reverse, torque the bolt on the balancer to I think 80 psi (someone correct me if I'm wrong)You can rent some of the tools at Auto Zone, or you can buy inexpensive tools at Harbor Freight. Search the forum I believe that there is a link to the factory manual.

When putting in a new front seal in the timing cover, I like to set the seal in place, then pre fit the harmonic balancer so the seal centers nicely on it and start tightening up the cover. I get 3 or 4 opposing bolts pretty tight, then I remove the balancer again to get the bolts under it and finish the cover tightening with a final run around torque.

I have seen more than a few front seals 'fail' because the play in the bolt holes of the timing cover will allow the seal to be 'just' off center enough to leak.

just curious, yes probably an obvious question, but im new and need to know. Can you place the seal in backwards? i think i may have.. and i can't remember how i took it out weeks ago, my manual does'n't specify if i put it in with the "covered Ring hole" side towards the balancer or the Open end(no cover with hole) towards the balancer..

any help?
