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 oil I’ve determined that I need a new engine (Engine replacement 1992-1995 Holiday Rambler Vacationer).

Since folks online asked if I would keep them posted on my progress (several are interested in doing an engine replacement themselves) I’ve decided to start this thread. I’ll try to photo-document the hi-lights.

My first problem was finding a place to do the work. Fortunately, I have a friend who has a place in San Marcos TX with a large paved area. He’s kindly let me set up there. The 160 mile trip in my RV from Houston to San Marcos with an engine I now know is on the verge of failure was tense to say the least but the old gurl had at least one last trip left in her and I’m happy to say I’m now set up in San Marcos (I’m certain the 50 weight oil I put in the engine helped). Today I’ll be ordering a rebuilt long block engine assembly from O’Reilly Auto Parts (thank you enblethen) and while I await the 5-10 days for delivery I’ll begin the old engine removal. It’s getting frighteningly close to the arrival of hell (aka summertime) here in the Texas hill country so I’ll probably have to limit my work time to mornings.

In my 67 years I’ve done about a dozen engine replacements, however having to install from the front looks like it’ll present a whole new level of mechanical misery.

  • When I replaced the engine on my old Allegro (454-holed piston), we removed the front suspension assy & dropped the engine out the bottom with the front end raised way up of course.
  • Hopefully you ordered a truck motor and not the less expensive passanger car version?
  • What about the oil analysis told you the engine was on the verge of failure? Are you planning any performance mods while the engine is out?
  • MY Buddy built a engine removal tool out of some 1/4" plate metal, that was welded so that one piece was 90 degrees to the other, then cut 2" diameter holes in the top piece (that is upright) and used the hoist to pick up the engine with this. It bolts on where the carburetor is installed, and actually the engine is fairly well balanced at that point.

    So the bottom plate is the size of the carburetor, and has 4 holes in it (flat plate say 5" or 6" square with holes the same bolt pattern as the carb. ) The upright piece is about 3" tall, and has a hole cut in it, so that picking up the engine it is balanced. (I guess a lot of practice went into designing that bracket). He built a couple of these to get it right. I was able to get a van engine out of a 87 motorhome in a short time using that bracket! Went back in really easy too.

    I know one member here that took out his radiator from a Bounder, and had it cleaned. It was a ordeal!

    My guess is that once the radiator is out of the way, then getting the stuff off the front of the engine is step 2, so it will be much more compact to remove it.

    Needless to say, marking all the wiring, and taking video will help in the re-assembly. After two engine, you probably already knew that 20 years ago!

    Good luck on your project!
