340 oil galley plugs

Yes I'm using new set of rings with a light bore hone and unfortunately a new set of Hughes retro lifters$. I suspect the trash is in the lifters and I can't take them apart to clean because the piston below the snap ring wont come out past the tie bar rivet. If I get the rivet out I'm not confident it'll stay in on reassembly.


OK on the hyd roller cam; you may be perfectly safe with that being the case. Examine the lobes and rollers before putting back in. I'd look for any signs of heated metal or scraping marks or anything like that.

Are you gonna replace the rings? I would certainly look hard at doing that. I suspect they will never seat in now; the surfaces may be hardened up. New rings would require a light fresh hone in the bores. No point in messing around on the ring seal, IMHO.[/QUOTE]
