removing the spacers between throttle body and engine block as per hurricane's recommendations

Agree 100% I will hopefully never do it again but if I do the throttlebodys are coming off !

Much quicker

A boost leak test might be the first thing to do here as its possible there are other places that may be leaking, and those clamps may not be leaking at all on many sleds.
Also, imo, these would be more likely to leak as the miles pile up because heat cycles cause rubber to slowly shrink and/or harden. If you are trading every year or two, I'm not sure I'd bother.

This has been one of the most unpleasant jobs I have ever done!!!!! Lol
I had all sorts of tricks...lol
I used a pick (straight and 90*) and slide the spacer on to tip and held the bolt with the 4 mm allen wrench and carefully slide spacer on the bolt.
Once i got the spacer on I would put a dab of grease at the end of a flat head screwdriver and stuck the nut to it then hoped for the best...lol

To do this over again I think I would strip er right down

Hey Marc, I tol ya it would be fun!! It's an ugly job!

If I ever have to do it again, I would also remove throttle bodies. It would make it much easier.

What time frame are we looking at for complete job?

Marc said it’s a 12-pack job. Hard stuff too not the watered down stuff. Plan accordingly!

Was there any sign of the clamps on your sleds either being loose or not clamping tightly?

I managed to squeeze a turn /turn and half on all the gear clamps .
The one gear clamp (intake to compressor on turbo) was just sitting there I was able to turn it on hose! Was tightened at beginning of season so must have rattled loose

Yeah, I was curious about that too so before I loosened any of those clamps I tried moving or wiggling the throttle bodies in those rubber boots. On both sides, the boots have ridges or steps to match steps in either throttle bodies or spigots on head so they seem to lock in pretty well (even without any clamps). Once I shortened the spacers, I could see there was definitely more clamp force as evidenced by very slight bulge in boots at all connections. You don't want to shorten the spacers so much that it crushes the boot out of round.
I shortened mine .075" (from .250 down to .175") and I think Marc shortened his .0625" (from .250 down to .1875"). Seems to be about the right amount.

I am curious if this will be a permanent fix or if they will need to be tightened again over time? It may be that the rubber the boot is made of is done compressing after a few years and then again time will tell. I started seeing leaks in the data log on my 2017 for the first time this year so just thinking I might save some hassle and just replace the boots instead of screwing with the clamps. Anybody having issues with leaks on the newer sleds or is this more of a problem for the sleds getting long in the tooth?

Don't know for sure. Maybe chat with Dave at Hurricane since he was the one who said they've seen it multiple times.
I think they can leak even when new. Especially for those of us who have more boost than stock. From what I saw, there really isn't that much compression on the boot with the stock spacers at .250" length. Maybe Yamamarc has thoughts?
