New engine rebuild smoking and oil fouling plugs

    +1  Everything so far is "armchair speculation" though well meant , "reality" is often far different than the guesses given. As I said before , Jim Grubbs Motorsports is a top notch operation. They will find the cause , no doubt about about that.

+2 Call Grubbs and get to the bottom of the issue(s)

If the engine builder is reputable, I would ship the engine back complete to have them resolve it.

I think if you start tearing it down, you own it.

I know of several shops where the warranty ends at the shop door on a high performance engine.

Yep,  reply #1 of this 4 page thread.

I have to stop plagiarizing!   

I hope you know I didn't think that . I should have put a +1 to show my post was done in agreement.

Well, I should have acknowledged you said exactly the same thing earlier, but the wink emoji was to signal I knew you were just confirming.

Perhaps I'm a little out of touch because I tend to do most of my own work when possible but doesn't $10,500 sound steep for rebuilding a HIPO 289?

About 9 days ago Bill sent them a detailed letter with Fords scoped findings!! I was told that the dad retired from the engine builders; so far from them " crickets " ! I disagree with the lack  of concern ! I'm thinking on my own part ( not Bills) that this " may " HAVE BEEN " a reputable builder ! I'm hoping for them to step up but last I've heard they have not responded ! I've become more skeptical with age and having so many cylinders bad I would not recommend them even so many here responding have had good results!

The oil control rings are not installed properly IMO.  The original builder should make it right and if they don't there isn't a lot you can do.  Sue them ?, you can if you want to spend $20K to get $10K back.  Just tell everyone you talk to about what happened and move on.  Their reputation will suffer and a lot of times that is way more important than the $.  Hopefully they make it right and you are moving down the road :-).

  Lots of "discovery" is needed before constructing the "hanging tower".

     As stated earlier, .............and myself somewhat familiar with engines and their potential failures, even with perhaps some formed opinion of possibilities in this instance, would suggest that without observant disassembly and components in hand by knowledgeable individuals, the rest being only speculation and innuendo, I don't believe it to be honorable to pass judgement here, as is so fashionable within perhaps lesser forum groups.

     The first thing to confront is the cylinder wall condition.Don't waste your time looking at the heads because the cylinder scratches didn't come from leaky valve stem seals.

+1 . Cylinder wall condition is compelling evidence .
