Front side of block oil valley plug?

[97_powerstroke77]

Just curious if the plug down below the alternator and behind the bracket is an oil valley plug or a water valley plug? It is about 1.5 inches in diameter. If so, I think it is the culprit of a major oil leak I have had for a long long long time...

there is a TSB for those leaking...they are actually the plug that seals the high pressure oil rails....when you replace it, expect a hard start as well....when it does start go run it about 10 miles hard....

it is a oil galley plug , is on the high pressure side of oil system and will cause a major leak ,94 -97 were bad for that , half inch ratchet to pull it out easy to replace

holy cow! I cant believe it is that easy! I have been looking for this for 6 months, thinking it was the turbo pedestal b/c of the buildup back there on it. I will change it and reply when I get it done, Thanks to all this is a major relief!

I bought this truck from a friend, and when he bought it it had this small oil leak that he said noone could find. Well It started getting worse after Ibought it. Ithought it was the hpop rings, nope. Then thought it was the turbo pedestal, nope. It was the oil galley plug on the front of the block.

Pulled the plug, put new o rings on it and teflon tape on the threads, voila!

No more oil leaks!!! I am happier n tick in a bucket of blood!
