Can't find any info on this one. It's a hex bolt on end of head, below end of camshaft, you can see plug wires exiting head at top of pic, bolt is at bottom. After running the engine, I noticed a tiny weep of oil from it, and doesn't seem very tight, wonder if it's got an O ring behind it maybe? Image Unavailable, Please Login
Those are plugs that close the oil gallery drillings on both ends of each head. #4 on the drawing. Occasionally they leak. Image Unavailable, Please Login Image Unavailable, Please Login
Yes It can be removed and replaced. But if its not leaking and you dont need access to the oil galley leave it alone. Id gander a wild gues your seals above are where the oil is coming from its not spick and span clean up there. Id clean the area drive it a bit and re check where the leak is coming from.
No oil from anywhere above, it just weeped a half a drop, engine is dry above and was just in the bolt area. Gave it a half a turn and seems to be fine now,will keep an eye on it. It had me concerned about turning it in more, as it hasn't bottomed out and wasn't sure what it might be blocking or adjusting on other end. Might just pull it and add a little sealer on threads if it doesn't do any harm for anything on the inside. I take it, it's just a plug basically, correct?
Mine does the same thing, I just wipe it off on a regular basis. It is also just a weep, very little leakage. My Indy mech recommended this which is a silicone sealer. He works on Jags a lot also. Figure I will address the issue at the next service or when I do the engine out service. Of course using a Jag product on an F car could cause untold electrical issues at any moment Image Unavailable, Please Login
Lol, yes, I'd be VERY careful using the Jag product, might even induce corrosion and rusting along with electrical issues!
