After 3 or 4 years of dealing with performance issues with my "6 Million Dollar Motor", all is well and my '26 is purring like a little kitten. A $7800 rebuild that seized after 2500 miles, 4 more tear downs, reboring the block, a new rear cap, multiple sets of pistons and rings, knurling the cam bearings, buying new cam gears, changing out the drums, balancing the transmission parts, countless new head gaskets, realizing that new valve pins are total crap, realizing that wrist pins are usually too tight, realizing that 3 thou of piston clearance is too tight, missing tours, etc.... priceless. Sending my rods out to Herm to have him inspect and straighten them...$147.00. Yeah.
I have had Herm do babbitt work for our restoration shop over the last several years and have been extremely pleased with the quality work that he does. I first met Herm with a "problem" engine too. It was babbitted by another shop and ran but knocked like a diesel engine. After 4 tear downs I called Herm. He straightened the rods and the engine ran like a sewing machine.
Straightening the rods: Is this something that should be beaten into all of our heads like the rear axle thrust bushings?
I'm starting to think yes. Something so simple but perhaps seldom thought of...
An old Ford T friend did a light rebuild last summer on another buddy's T engine in a tractor conversion and I was sickened when I heard all the rattling downstairs.
The 23 engine in the 18 Runabout is in dire need of attention downstairs and I'm glad this subject has been brought up as I hadn't thought about it in awhile...
I like sewing machine T engines under the hood.
It definitely should be part of any rebuild and right up there with bronze thrust washers. I've got a recently purchased RPU that sounds loose in the bottom end but has beautiful compression. Rather than just re-shimming the rods and mains, I'll send those rods out to Herm, also. Time well spent for sure.
