For the benefit of others, a strong shop vacuum can be your friend here. My experience is to remove the intake manifold as carefully as you can without disturbing the turkey tray. Vacuum out everything you can that OS on top of the tray, then carefully remove the tray all together. Now vacuum everything down in the valley. When you think you have sucked up everything, vacuum twice more, this time using a paint brush along with the vacuum to be sure all the nooks and crannies are clean and clear. That will usually get the hard crusty junk out before it can get washed down into the engine. Mount the gaskets with RTV on both sides around the water jackets and cross over blocking plates. Let them sit for a while so they won't easily move. Put a good bead of RTV along the china walls and let it tack up a bit. Use the stud trick to align the manifold and drop it cleanly and gently into place. If the gasket does not sit properly aligned with the bolt holes, lift the manifo
ld off, clean everything and try again. When all is right the manifold will go into place and the gaskets will stay in place as they should. If you are doing this with the engine in the coach it will help if you employ a strong young mechanic to do the lifting and positioning. Follow the manual sequence for torquing the bolts as that sequence is different from other vehicles. Once the manifold is torqued down, put a glob of RTV on your finger and wipe it along the edge where the manifold meets the china wall to make sure that area is properly sealed. This process worked for me anyway.

I did this process twice. First time I had too much silicone and it leaked antifreeze. Second time right. You will find crud when you remove the mfld. Be very careful to prevent crud from dropping down into crank. ?Very careful. ?I think I lose some stuff and even drainging the oil and flushing more oil thru something got in. I got 500 miles and a bearing went. No fun.

Jim Hupy as well as the shop working on our coach said that they recommend
using "Right Stuff" rather than the Black RTV.
I triple vacuumed and sealed off the bottom while cleaning.
Having done it twice - I would NEVER attempt it again.
