Rear cam plug question

[Horsman]

I had an oil leak at the rear cam plug, then installed a new cam plug with sealant and it still is leaking, see pics.

My engine builder used a 2 5/32 inch plug, wondering if it is the wrong size.

Thanks in advance.

It is put in the wrong way!  FEs ( with the proper FE style cam plug) go in the OPPOSITE way of what you have done. The "cupped" portion goes TOWARD the camshaft and the plug is tapered to allow that. That should fix your problem.

PARDON MY STUPIDITY , I now realize the engine is a small block. The plug IS installed correctly. All I can suggest is spray with brake parts cleaner and apply silicone sealer all around the plug's edge.
    I am wearing the "dunce" hat and writing pardon my stupidity  on the chalk board.

      FE?   Randy, put your glasses on!       

      Yes, 2-5/32" is correct for the SBF.

    I drink HEAVILY!!! Seriously I didn't look at the oil gallery plug orientation. My bad. At least I kept saying FE. My apologies to those I misled!

Thanks for the information.

Any ideas why the second install is still leaking oil?

Thanks for the information.

Two guesses:

1. There is a nic in the area of the block that the plug goes into maybe from when a previous one was removed
2. The plugs are out of tolerance. Are they made in the US or are they off-shored where close enough is good enough

Checked for a nic when I installed the first plug, all looked good.

Engine builder provided the plugs both times, I feel they are probably not US made. Any recommendations for a good US product?

I've always had good luck with Dorman. I checked their website and they recommend two cam expansion plugs for a 289 which seems strange:

1. 555-051 which is 2 3/16
2. 555-070 which is 2 1/8

Their site says both are 0.060" oversized

I would go with the 555-051 but you may want to first call their tech support line to see why they list 2 different sizes 1-866-933-2911
