Some of you might recall that I did the swap involving stripping the Hyundai V6 engine down and replacing all components with parts from the Mitsubishi engine...there was a thread on here several months ago.

Soon after getting the truck on the road, I noticed a slight oil leak (size of a nickel overnight) under the truck. Looked under, and appeared to be coming from driver's side front corner of oilpan. However, upon closer inspection, it looked like it might be coming down the front of the head...bracketry involved in that area, etc, so it was tough to tell...

Long story short, it started leaking badly today. I degreased it and looked closer, but cannot really tell where it is coming from. It appears to be coming from above the AC pump area, on the front of the head. I can't see any dripping from the bottom of that bank's timing cover (the bottom edge of that is located right in the area of interest...where the oil is most prevalent). Anyway, by powers of deduction, I would say my leak is either the camshaft seal or the o-ring that's in the back of the "distributor adaptor". This o-ring is internal to the assembly. The thing is, from looking at the diagram on page 9-87 of 1989 Montero manual (free download on sticky page), I cannot tell where the o-ring sits in the housing. See, my first idea was that it was the o-ring, because the oil does not appear to be inside the timing belt cover (although I don't have it off yet). So, I assumed it might be the o-ring letting oil bypass back through the assembly toward the head, and down through the meeting flange of the distributor adaptor and head. I hope this makes sense. Anybody have any ideas here? I didn't take the distributor adaptor off the Hyundai engine, because it only had 65K, but in hindsight I should have assumed the seals might be dried up. Plus, I had the sprockets off so it would have been an EASY fix. Now, I'll have to take the whole f&^%ing front apart, retime, etc, etc, just to replace a damn o-ring and seal. (I'll naturally do both when I'm in there).

Anybody have any experience with a leak here? Please let me know, if you do...

Also, would anyone know where to get the o-ring that is in the back of the distributor adaptor? I've looked at rockauto, o'reilly, etc, and they list nothing for it. I hate to have it apart and have to try to find one from an o-ring kit at the store...that sounds a little dicey. If anyone has a part number or any info please let me know...
