Cracked them Sleeved? Pulled the head of my new 40 sedan due to low compression on #2 cylinder. Found a bad exhaust valve. When I was cleaning up the block I noticed a few cracks one from the valve seat to the cylinder and one from the coolant passage to the cylinder. All cylinders seem to be sleeved with a .100” wall thickness. All stamped with FC Also one stud looks to have a thread insert installed It’s an old Ford rebuilt flathead with a date tag of 1948. I’m wondering if the reasons this engine is sleeved is due to cracks and this was Fords Fix. Just asking if anyone has seen this before? The engines getting a new valve lapped in and going back together to see how it runs.
Love that Ford Canada valve. I’ll have to check my pile of stuff to see if I have any. Love your avatar! Picked up my ‘32 5W off my uncles farm in Airdrie which he traded and old house furnace for...
Not an answer, but I have read Ford sleeved blocks, maybe for replacements? Also regarding your tag, may have been one from an authorized Ford place? That was a thing way back when.
Years ago, the Ford Authorized rebuilder in St. Louis was called Mendenhall Rebuilders. The building is still standing, but I think they are gone. I’ve installed more than a few of their engines.
Yes, the equivalent of a 1948 crate engine....remanufactured by a Ford Factory authorized builder and very likely swapped at a Ford dealer. Yes, sleeves can be used to address cracks into the cylinder. I am betting you have a real good runner there.....let us know
Thanks yes my Roadster has been a blast the last to years only thing it lacks is seats for tge entire family. Hence the 40 sedan. I’m thinking there is not to many 32’s sitting on farms around Calgary any more. The engine has a mix of old mushroom valves and newer straight valves. The Ford script valves are the straight ones
Lou Meyer and Lew Welch (Indy 500 winner and the gent who funded the Novi, respectively), ran the Ford authorized rebuilding plant in LA, before WW II. More useless trivia popping into my head.
I’m hoping so. The cylinder walks are glazed with some pitting but we’re all around 85PSI compression. It seemed to run well and no smoke on 7 cylinders so hopefully 8 will make it even better.
Ford really pioneered the remanufacturing industry, and you have an artifact from the early days of an industry that really got it's legs under it during the war rationing of WWII. I rebuilt a flathead for a friend a number of years ago that had all 8 holes sleeved back to the stock bore by a Ford authorized remanufacturer. Pretty amazing that these things can still be rebuilt and run happily 80+ years after they were first manufactured.
https://www.jalopyjournal.com/forum/attachments/img_1588-jpeg.5858746/ The stamped characters in the deck that lead across the sealing surface look like a potential leak to me. The other scrapes and knicks suggest the block needs to be decked maybe .015" - .020", maybe more.
Yeah all the liners were punched with FC. Not sure why you would stamp a combustion sealing area. It could use a good decking but hopefully a graphite head gasket will seal it up. I’m not planning on going to far into this engine if it’s going to need more than a valve and gaskets I will go another route. managed to clean the rust scale out of the one cylinder head. I will have to pull the other side and clean out the block as well. The round nuts look to be cherry pits I flushed out of the rad at sone point this was a nice little home for rodents
I might be wrong but I think there were 40 Fords that came from the factory with sleeved engines. I built one years ago That came out of a sedan that had never been touched and we pulled the sleeves, honed the walls and used Ford tractor pistons for the rebuild. The sleeves in that engine had nothing to do with cracks.
The 59A that came in my 40 has all 8:cylinders with thin wall sleeves and a factory relieved block. This crack from valve to cylinder was apparently the cause of its occasional overheating that eventually led to its demise. It’s been yanked now for a (gasp) SBC.
HotrodA, that block doesn’t have the thin sleeves in there anymore. And, that’s not a factory relief. Looks like a hot rodder pulled the sleeves and cut their own relief. Then beat on it til it cracked.
