Series 60 Tune Up ?
-
Adjust the valves at 100000 miles its cheap insurance I do all my trucks at 50000 miles when they are new then at 100,000 miles never a problem with them if people say not to tell them to pay for repairs when it breaks down on highway just my thoughts had generator done at 2500 hours they where out put new thermostat in also poor maintenance means break downs take your chances or do it just my thoughts

My royale has had overhead done runs great good mileage

My opinion, unasked, but with some past exposure and industrial training is; unless there is evidence such as a significant drop in mileage or performance, or oil analysis that suggests top end wear or damage, there is no need to do a valve adjustment that soon. For one thing, RV use will never approach the severity of fleet/comercial use. Another is that the materials/metallurgy used for pushrod ends, valve stem ends, camshafts, rollers, etc., is far superior (and far more costly) to consumer gas engines. I have checked clearances on a number of gasoline engines, and a few diesels – particularly the 3208T and 1145 Cats. After 125K or so miles, on a (non auto) diesel I would expect to see no appreciable wear measureable with feeler gauges or dial indicator, even with mechanical (non-hydraulic) lifters. Checking valve train clearances was reassuring, but a pain, and thankfully proved unnecessary. I might add that a series 60 is much more of an engine to manufacture than the Cats I mentioned; the 60 is a sleeved and slippered engine. I think I would expect injector issues before valve clearance problems. If something non-catastrophic has gone off, I think it reasonable to expect to see evidence in the oil.
Having said that, I will have to have my oil sent off for analysis now.

I wander if adding pre oiler on the diesel engine that sets a long time can help the lifter and cam condition. Many airplanes the set a long time use a pre oiler prior to starting the engine, that improve the cylinder, cam and lifter life.

Pre-oilers have been widely debated on some yacht forums. The general feeling is that they can’t hurt. It’s also the opinion of some with lubricant expertise that sufficient oil film is maintained for quite a while.
