Make sure you check those bolts. Bert Curtis wired mine. After we pulled the first blown engine I have not rewired them. Every time I check the driver's side, they are loose. The plan is to rewire them. My passenger side bolts are always tight. I have been around when a couple of axles came loose. Not a good sound. Can you imagine that axle flailing around under there? There are a couple of guys on this net that can tell you all about it.
Takes 3 minutes to snug them. I can wiggle around and get all of mine from the top. At least this time my header bolts remained tight. Using the thick Remflex that Jim K. gave me. We have about 3500 miles on this engine install. I had 2,000 on it last time I had to tighten the header bolts.
I think being able to see our engine, from the driver's seat, keeps me checking things before each trip. All intake bolts were tight, but as usual, had to snug the tappet cover bolts and the thermostat bolts.
Looking forward to seeing our friends next week and praying for "uneventful" trips for everyone.

BTW--the same goes for those fan clutch nuts if you recently fooled with it.

Good thought Dan,
I am going to be under the coach real soon, I'll check one those while I am there.
I am a great believer in safety wire or keepers.
I did try to drill the replacement screws, but they are grade 16 (or something like that) and it is really tough on drills - even solid carbide. If someone has a EDM drill, it would be neat to get a bunch done. That or have a water jet (cheaper than a die set) punch out a bunch of thin metal keepers we can bash over the double hex.
Dave Lenzi drilled the SHCS he put in the CV joint of his steering shaft. I've done this other times and found it took a lot of patience and more than a few scraped drills and fasteners.
Let's keep thinking about this one.

We sell lot of those bolts and washers.
They are special and expensive, but worth replacing once every 100,000 miles.
Our shop is instructed to always use the BLUE Locktite as the RED is
too much grip, and not necessary.

Michael, the replacement bolts are 12 point and they are a 7/16" wrench
size. They should be replaced each time they are removed, and should be
grade 8. The bolts used on the drivers side of the coach are slightly
shorter than the ones for the passenger side to allow for clearance on the
final drive housing. New SAE lockwashers should be fitted and it would not
hurt to use a little BLUE loctite thread locker when they are installed.
The tightening torque is 75 foot pounds, which is a lot of torque, and is
the reason that new bolts should be used every time. If they are properly
tightened, they should not loosen up, but that being said, I have
encountered many loose ones on the drivers side of the coach, like finger
tight and missing. Rarely do I find loose or missing ones on the passenger
side of the coach. A tight fitting socket must be used, and it helps to
have a 20 " extension on the socket so they can be tightened from the wheel
well. It also helps to have the shock absorbers out of the way. Lock tabs
would have been nice, but were not fitted at the factory. Replacement bolts
can be purchased that are already drilled for safety wire if you are a belt
and suspenders kind of guy. After initial run in, check that they have not
loosened up.

I have gone out on two different Black List calls for people sitting at the side of the road and their coach will not move. Both had all of the bolts missing on the driver's side. Both had recent work done and the mechanic obviously did not torque them properly. Both were on the week end so I could not get replacements from the GM places. So I used the softer grade 8 fine thread bolts from TSC and sent them on their way with instructions to get the bolts replaced with the correct ones which are harder than grade 8. After the Black List second call I ordered a set of replacement bolts and washers but no one has called for help since then.
You can get them from Jim K. (preferred), or GM, or McMaster. With Jim K. you know you will get the right item the first time and now that he is using Fed-EX it will arrive in a reasonable amount of time.
I ordered an item out of Omaha yesterday (Friday) at 11AM and had it shipped Fed-EX ground (home delivery). When I looked on my porch this morning (Saturday) at 11AM it was already delivered and sitting there. I do not know when it was delivered but it definitely was before 11AM on a Saturday morning.

This sounds dangerous.
Are you guys refering to something that is checked after an engine or tranny change out or are you saying that even from the factory there is a problem with bolts coming loose under the hoot?
Unless Jim B had checked them, I have not looked under there for loose anything.
I sure don't want to head for trouble down the road... lol get it, down the road...
