    +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 Iím a little out of touch because I tend to do most of my own work when possible but doesnít $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 ď crickets ď ! I disagree with the lack  of concern ! Iím thinking on my own part ( not Bills) that this ď may ď HAVE BEEN ď a reputable builder ! Iím hoping for them to step up but last Iíve heard they have not responded ! Iíve 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.       :)

having so many cylinders bad Iwould not recommend them

In post #12 you indicated that cylinder #5 was the problem and then post 32 indicates oily cylinders seen from scope. Were those plugs fouled as well and all on the drivers side? What did the passenger side show? Can you post a copy of the report sent to the shop?

If the motor will be coming back out, I would start with that and look inside the exhaust ports to see if the valve stems are oily which will confirm or eliminate the exhaust guides. This will also keep the motor buttoned up and under warranty if one was given. Itís not the perfect answer but a place to start while trying to get the builder to takes some type of action.

     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.
