Wet sleeve explained
here is a video on wet sleeve vs dry. it also depicts the importance on maintaining coolant integrity. 8v92 6v92 and series 60 are wet sleeve the kubota gensets are drySleeved.
the two stroke V92's have intake/exhaust ports on the side of the sleeve and require more sealing surface . minor pitting near a seal on the waterside can let the seal go. and dump coolant in the oil. cylinder sleeve video The FC and SP 3208's have not a sleeve so a single cylinder inframe is not possible.some call the 3208 'throwaway engines' becauseit is always completly rebuilt at the failure of one cylinder wall (3208's are notorious for waterjacket issues at one cylinder so coolant integrity is as important).problem with a sleeved engine is once your engine looses coolant you cant tell how compramise all the other seals are and a total rebuild is prudent. kinda think that is why private coaches are rebuilt more often than just repaired Greg |

Greg: I can tell you first hand now, that a sleeved engine is flawed
and the failure of any seal, unless it is idling, will cause catastrophic failure and total rebuild. This is true especially if you expect any kind of warranty on the work. Your warranty for a partial is only 30 days. BIG DEAL!. I just lost my engine in less than 1.5 minutes from first indication of a problem. I'm sure the whole purpose behind the sleeved engine is less weight and cost in manufacture, but it makes the user the scapegoat in the case of any failure. To make matters worse, the warranty for a re-build is awful as it related to motorhome use. The factory only gives you 12 months and unlimited mileage. A commercial vehicle such as a long-haul truck can log up to 50,000 miles in that 12 months and it is a good warranty. The average motorhome owner only puts on around 10,000 miles in the same period and usually less than that. Not much of a warranty under those conditions. I could purchase a used FC for the price of one engine failure in a Detroit 8V92. Detroit gives much better warranties on the Series 60, but it too is a sleeved engine. I wonder what the failure record is on that one? R.E.

I posted that for you to have some insight info when the shop
called. Kinda thought it was a sleeve seal when you said it emptied quick. a cracked head and waterpump gasket would take some time. you can always only drop in a sleeve to repair the bad one if you didnt get things too hot. the garage is gonna sell you the works because they can and it is sure to get any other issue that may or maynot exist delt with. get a price on dropping in some sleves or just the one to bring it to a local with better US craftsmanship. a trap door in the bedroom closet would speed a rebuild up and reduce labor cost.

Wet sleeve explained
I have read the wet sleeve commentary:
In the industry we always called the DD engines dry sleeves because there are no rubber O rings to speak of when you place the sleeve in the block.It was a pressed fit. we sometimes would put the liner in a freezer to shrink it and slide it in the block, I am talking about 1970 -1980 era engines. 2,3,4,6,8- 71 series enginesA wet sleeve has o ring seals on top and bottom when installed and dish soap or other lubricants are used to seat the rings in both the sleeve and the block.
almost all of cat older engines except the 3204 and 3208 were sleeved, this allows you at over haul to install all new wearing surfaces and basically restore the engine to the orginial specs., same as DD.
although not done often 3208 can be repaired in chassis,you can hone the cylinder wall and install an over sized piston and ring in one hole only if the damaged was not to severe, i think the O/S piston and rings came in 10, 20 thousandths. you can remove the engine and have a sleeve installed in the hole and bring it back to standard. Number 7 and 8 cylinder were where the damaged usually occurred from over heating due to the design of the water circulation starting in the front and working its way to the rear of the block.
3208 you either love or hate them, I have seen many run to 300,000 miles and quite a few up to 500,00 miles

They already have it torn down. It would cost a bundle to just put it
back together to get it back. Heads overheated, but I have no way of knowing if they are really damaged or not. Overheat plugs did melt. I'm pretty much at their mercy. If they only replaced the two damaged sleeves that are obvious and the engine failed again on the return trip, I would not have any warranty at all. Most of the overheat happened after the shut down because most of the coolant was dumped. R.E.

Ron,
Sorry that you are grounded. Words can't begin to console a coach owner with a broke motor. Been there done that, three months after buying my coach. New cam & stuff $5K. Best you can hope for is they do a good job and you get the warranty. Anytime this happens I just tell them fix it like it was yours and walk away. Say a little prayer that it works out. When they are done with it go back up there, get your coach and DRIVE BABY DRIVE! It's your only good option.
