I hope that the plugs are the same for the two blocks, the P and the P40. From old posts from RiverPatrol I have them at 40mm for the side plugs, and 50mm for the ones on the rear (block and head). But I think they should match exactly a measurement in inches for the P engine, which they don't.
Again, you are the guiney pig on this one! Thanks.
My side ones match perfectly - 1.57 inches, which is 40mm on the dot.
The larger ones also measure 1.97 inches, which is 50mm ...
I found a full set of PPU freeze plugs, and the more research I do, the more I am coming to the conclusion that the PPU engine and the P engine are one and the same... So I am ordering the PPU set.
Let's hope I'm right
