I came across a puddle after letting the car sit in the garage for 3 days (i.e. I've been to busy the past few days to take a look at the car. I knew it had a coolant issue. I now know that issue to be a cracked radiator). The photos are after I somewhat dabbed the seam area circled to determine what was leaking. It appears to lack any red tint, so I assume it's oil.



Would replacing the applicable seal for this be within the scope of a beginner mechanic?



It also looks like I need a new seal for the camshaft sensor.

Im not sure what is shown in the top middle pic. Can you see any oil leaking from a higher point? The rear valve cover gaskets tends to crap out

 

The middle and right pics are of the same spot, the middle pics being from an angle slightly more to the left.

Thanks for the mentioning that about the rear valve cover gasket. I'll look into that.

 

Rear main seal(half-moon seal as well) on the tranny pic Ive had a few max's with this issue....

It will require to drop the tranny and the upper oil pan to replace.

 

Where is the rear valve cover gasket? I see the front. Also, is it complicated for a garage to replace the main rear seal? There is no danger that the tranny could be not in the same shape when they put it back together?

 

The rear VC is on the opposite side of the front VC underneath the upper intake manifold.

A shop would be to replace the RMS but it would come with a price. And they dont take apart the tranny they just need to drop it to gain access to the RMS. They might reccomend to replace the clutch and flywheel since there in the area.

 

Thanks Product_Of_Korea for your comments and link. I'm going to have to preuse that link and search for other threads here very thoroughly. I guess I'll just watch my oil consumption for now as it's such a slight leak. I am actually running slightly overfilled, so it's kind of a blessing in disguise right now.

Besides the clutch and flywheel, which I'll pass on personally, any other "may as well replace while in there" parts?


Ed O, welcome to the forum.

 

the oil could soak the clutch to much. you may see some slippage....

 

I second the notion of the possibility of valve cover leak. I had a small amount of oil residue in the same area, but it was dripping down from the rear valve cover. Once I replaced the rear valve cover gasket it was gone.
