Rocker shaft plug
 

Which way does the rear rocker assembly plug go in? Exposed metal cup facing in or out?

Flush side out.
I usually install those plugs DRY.....and when I am installing the rear Camshaft Cap......and I place the Ultra Gray RTV in the "shaded areas" shown in the factory service manual.

This pic is from the Haynes B2200 manual though.....

Confirmed. I think we got it right this time. I did wipe the excess flat on the front surface before it set so the front cover gasket had a flush surface to seal against. Used a skim coat of rtv grey on both sides of that gasket too

I have that same Haynes manual. I’ve done this rocker shaft removal and install more than once before this time. It sealed up good the first time but for some reason it didn’t the second time.

I remember being skeptical about putting the sealer too close to the cam bearing surface. I didn’t want the sealer spooging onto the cam bearing surface. This time I just put it ​​​​​​in the entire shaded area as suggested in the manual. I did have the mating surfaces spotless clean and dry. However I took a clean rag and soaked a corner with wd40 and rubbed it on the cam bearing surface. My goal is that when the sealer hits the bearing surface the WD40 would repel it from sticking where it should not be. I also but a small dab of assembly lube in the top of the cam bearing surface. Just enough so when the cam rotates it will distribute the lube. At the same time, the small dabble on top won’t smear all down into the flange sealer and prevent it from setting properly. After setting it all together like this I have not rotated it yet. I want that sealer to set up good before it starts sloshing oil all around in there.
