Any advice?
I'm currently rebuilding my 2500 lump and have all the necessary plugs from Chris Witor - the old ones were removed by the machine shop.
Do they go in dry? With Loctite? With RTV?
Are they supposed to be a tight fit? Do they bottom out, or do I just drive them in a certain depth and leave it at that?
The large one at the end behind the backplate feels quite tight going in - almost like it's cross-threading but Chris Witor's stuff is normally right for the job so maybe this is just how they are? Threads seem clean and in good condition.

Hello LLessur,
they are tapered pipe plugs (NPT I think?) and should seal dry. However I would use a modern liquid thread sealer as a belts and braces approach.
I did not follow my own advice and recently had to remove my rebuilt engine (Twice, as I blamed it on the rear oil seal which it wasn't) as the rear gallery plug behind the back plate was leaking.

Re: Oil gallery plug fitting
Thanks Alec, very helpful. I'll grab some thread sealer
Do they definitively bottom out or do they just need to be done up until tight/flush with the block etc?

Hello LLessur,
yes, the tapered thread just jams tight, not to a specific depth, depending on the tolerance of the tapping and the plug. So some liquid seal and screw in tight.
