She's in and running ! But I found some blue smoke coming from the tail pipes . Did a little diag with propane and in the valve cover .

I found 3 valve seals lifted , These are PFTE seals . So I'm going to change all the valve seals to viton metal body seals . The ones that comp sent me are like a hard plastic and very brittle 503-16 part number . But I'll have that done this week and I'll splash down sat at the local lake for some piston ring sealing time !! WOT - Idle ... "repeat"

. Lake test day !! I tore the entire top end off due to valve seal leakage , replaced with viton metal case seals and they are not coming off , started up and timed to 12* , will see if she wants more timing . But I'm ready to see how she feels ! Wish me luck !

Lively - with your engine build did you replace the manifolds and risers? Mine are original to the boat from 88 so I'm leaning toward changing them out since 1) I don't know the history of the boat, 2) the engine was DOA, and 3) from what I've read I'm not coming up with any conclusive way of testing them.

My original ones from 6 years ago were cracked , and were leaking , no easy way to test , but if they look like hell and rusted on the outside I would look into some new ones . I paid like $600 for the set

Went really good ! 50 mph at WOT and maintained good oil pressure . Acme 541 prop was amazing !
