Good news, Lawn Art's engine rebuild is complete and we will probably get her home this month.

Back in October of 2020 we blew a lower radiator hose and cracked the head. When we got it to the shop and they pulled the head, they found catastrophic damage to the block. There was a gouge between between a few cylinders. The last mechanic that worked on the bus reseated the piston sleeves above the top of the block to make a bandaid seal.

We chose to do it right, it's our retirement ride so we started with another block. Our mechanic Dusty at J&R Diesel in Riverside, CA built us a beautiful new engine. It runs as good as it looks.

I am not a mechanic, so any work above my ability level get done by a professional. I have found it is cheaper for my wallet in the long run.

Lawn Art's first official outing will be the SoCal Mini Rally in San Dimas, in March.

So if you want to see the bus that started the GM Survivor's List project, it will be there.

Wow - now there is some actual art in the back end of Lawn Art. That looks great. Many safe and happy miles to you!

Congratulations Jon! The engine looks and we're sure it runs great!
We have less than 15000 on our rebuild and just love it and the pep it has after driving it many years with a tired engine.
You have a unique bond with your 4104 & we admire that as we do the same. Enjoy your future years in a young old bus.

That is a beautiful thing. I have not met you but I picture a permanent smile on your face as you drive it long enough to break in a NEW engine.
Safe travels.

Nicely done Jon!

maybe we'll see you at the rally.

I've been watching the progress of this rebuild for the the past many months as I'm in and out of the shop, where I've had my own two Crowns stored, for years, as well as being friends with the guys there. I saw the old block where it was dipped down between the cylinders, very interesting indeed. I haven't been there recently to hear it run but I hear it sounds great, as it should. Congrats on a properly done what amounts to a complete re-man to include a whole new block, actually a full blown engine swap.

I'm more interested now in hearing about when and where this Rally is to be in San Dimas. I'd like to attend and bring one of my Crowns, if they'll allow a non-coach to attend. I'd also like to meet you and check out the finished 4104. There may be others there I might know.

I speak from many years of experience, there isn't anything quite as nice as a well running and tight driving 4104 on the road. I love 'em. I always wax ecstatic about how awesome Crowns are to be driven, anywhere really, so don't get me wrong, I'm not being two-faced here. I stand on everything I've ever said about Crowns on the road etc. But the fact is that the old GMC 4104, 4501 Scenicruiser, which I owned and operated for 4 years, and most of the rest of the GMC coaches are the epitome of how a coach could and should handle. They are superb and driver friendly and were the state of the art at the time. A true joy to drive, even though they do have definite limits since they were designed for flat paved highway running. That's why I balk at having one for a conversion and used for exploring unknown road conditions. Thanks but no thanks. Been there done that in commercial service. Hope you can hook me up with Rally organizers so I can make arrangements. Thanks, and Happy Motoring in your brand newly powered 4104.

The SoCal Mini Rally is at Bonelli Bluffs RV Park in San Dimas March 17th to March 20th.

Bus Conversion Magazine is sponsoring the rally. So you would need to contact Gary Hatt about bringing a seated bus to the event

Campsites were $77.00 per night last year when we booked our spot.

My understanding is we have 28 coaches booked for the event.

Was that a low block 6-71 that dipped ? DD are strange puppies I have a 8v92TA here the block deck has raised so much you cannot pull 4 liners from it even with the liner puller

siberyd · « **Reply #9 on:** January 17, 2022, 08:30:07 PM »

I believe so, it was like someone took an ice cream scooper and scooped up the metal between cylinders.

The were bad about that, we would weld the dip and grind it down to get one back online knowing the block was going to be replaced when it came in to the shop with the newer style block

Sounds like you will need to rename your bus to "Road Art".

Thanks for the Rally Info. I'll definitely contact Gary and see about bringing one
of my Crowns to visit. At least I can come by car to meet and put faces to
some of the usernames here. Have fun with your new re-powered 4104.

Coach and Crown,

Thanks, we will see you there.

It's like stepping back in time to see that engine so clean and I believe original color.
Now you could have been mean and painted it red to make it look like a CUMMINS but I digress.

luvrbus · « **Reply #15 on:** January 21, 2022, 05:18:16 AM »

Detroits come in a lot of colors me I liked the blue the aluminum block 6-71 were or the red, never was a fan of the alpine green

chessie4905 · « **Reply #16 on:** January 21, 2022, 06:12:25 AM »

Detroit probably picked that color to make it instantly recognizable. At least it made seeing oil leaks easily. Lol

The white one were easier to find oil leaks on lol

Must be why Ace painted his white.

It was Partially white, only what you could see from outside. It was what you couldn't see on the inside that was the shocker.

Silver 92's = the best

They leak too

I thought Double 0-92's were the best

Hey I have seen that engine before.

Double OO (owner operator) engines were between the green engine and the sliver they had a problem and didn't hang around long

Boomer · « **Reply #24 on:** January 24, 2022, 12:19:57 PM »

10-4 on that. I had a new black OO 92 and it only lasted 250,000 before it broke a connecting rod and destroyed it. I remember it came with flames painted on the exhaust manifolds, never seen that before. That and a broken cam follower on a V12 were the only failures I ever experienced in millions of miles on all kinds of Detroits. Oh I experienced a couple stripped blower drive shafts on 71's but that is a minor inconvenience.

BusNit · « **Reply #25 on:** January 24, 2022, 05:15:03 PM »

Yeah, I got some flack on the FB Detroit 8v92 forum when someone was touting the OO as the greatest thing. I made a comment suggesting it was a marketing ploy and some fancy paint. Didn't go over very well...

That looks really nice. Glad you were able to get it rebuilt. I am wondering how many shops local to me will be willing to help me out when I am ready to start swapping fuel lines, gaskets and such. Really don't want to do it myself. Enjoy it! Looks ready for a nice long trip.
