My Engine replacement odyssey - 1994 HR
My engine replacement odyssey has begun. I posted questions about the 460 V8 in my 1994 Holiday Rambler some time back and after much engine diagnosis and finally laboratory analysis of my crankcase o...

Another milestone in my engine replacement odyssey this past Sunday! With the help of an old friend Mike and my new friend mpaton who I met through this board, the three of us installed the newly rebuilt engine in my RV, and what an ordeal it was. However, it was particularly useful that mpaton had done a 460 V8 install on his RV and knew many of the pitfalls from hard earned experience. I was pretty achy this morning so I spent my time on the internet searching parts and doing things like taking the alternator and radiator to a local rebuilding shops for inspection and refreshing. I really don’t want to have to dig into my RV’s mechanicals for a long time to come!
Here’s a photo of my RV’s newly installed motor, ain’t she pretty!
BTW, though I was satisfied (though not happy of course) with a chemical analysis of my crankcase oil showing highly elevated metals that were associated with engine bearing failure, mpaton wanted to autopsy my old engine. I’d traced the knock down to the upper end of the #8 cylinder, hence the valve lifter misdiagnosis, so we took the bearing cap off the #8 connecting rod.
Yep, no doubt about it now, it was a rod knock! However, it’s still disturbing to me that three separate cylinder balance tests and a thorough running engine survey using a stethoscope wasn’t able to pinpoint the location of the noise to the bottom of the engine. Nor did the noise decrease when the spark ignition to the #8 cylinder was cut off.
All I have left to do is reinstall the myriad of parts and accessories I removed to finally get the engine out. Unfortunately, the dreaded summer heat is now a daily reality (it’s currently over 90 degrees as I write this) I’ll probably only be able to work a few hours each morning before the heat shuts down my efforts. Still, completion is now on the horizon!
