I decided to check out the underneath of my car (94) today while i was getting my wheels rotated and i noticed a black glue/tar substance slowly leaking from my timing belt case. It isn't all that liquidy like oil or anything, however, it does look like a leak. Just got my timing belt replaced last week from the dealer. Anyone know what it could be? I'm thinking its just some protective glue or sealant that was recently applied and probably melted?
I'm gonna call the dealer and ask him wot the **** he did to my car after all that $$ i paid him !
Just wanted to know your thoughts on what it could be.

thanks,

mahesh

I was trying to figure out the same thing but no luck. I notice the same thing when i have my car on the lift to change out the rear tranny mount. If you are able to figure out what this leaky stuff is, please let me know. Thanks!

I think I know the answer

I believe you have a leak from your camshaft oil seal. If you take the plastic covers of your timing belts, and look behind the to camshaft gears and the crankshaft, you will probably find the source of the leak. I think the tar is baked oil. The fact that its hardened, means its probably a very slow leak. I have it two. the two camshaft oil seals are pretty cheap. I am going to fix mine when I change the timing belt.

Not to worry...

That tar-like substance that you are seeing is the coating for the crank angle sensor that has melted and run down the front of the block. I'm told that it is perfectly normal for that to happen and that it is not operation-affecting. FYI, I installed a new CAS last year at about 140K miles and the new one did the same thing within a week. It's all good---- :D :D :D

Yep, stevieray hit the nail on the head.

I called my dealer and he said the same thing. If it were a cam shaft leak or something of that nature, there would be oil on the ground and it wouldn't leak slowly nor would it look like tar/glue.

Alls well that ends well :D

Thanks stevieray :)

This is right on! I found the same thing after my headgasket repair. The only difference is that my car would not fire up after i took the CAS sensor off and reinstalled it. I had to replace it to get the car to start. I CAN cause issues but only once it has been removed once.
