I’ll look over everything in detail and get decent photos later, was taking these with oil all over my gloves and lense. Just from a basic inspection, there is nothing I can tell… other than the crankshaft split in half. none of the bearings spun on this engine, some are pitted and scored but non spun. There was no event, I was driving down the highway at 65mph, pushing 8psi or so of boost and it just started clattering and knocking, still ran fine and started just fine. Figured I had spun a bearing but it turned out that the crankshaft was split. I did a long road trip across America a year before the break and proceeded to drive it around in the mountains my first year of college, pedal to the metal 3rd gear uphill most of the time anywhere just to keep 35mph. My max psi was 16, very rarely 18 if I was in low range PULLING. I would never want to hold it that high though, tried to stay around 12.
I should have explained further, these are 2 different engines. The engine with the blown crank was my first original engine, put around 50-60,000 miles on it in 2 years. Half of them were with the turbo. Then I got a 2nd engine, swapped it in, put 150 miles on it andddd it started knocking. At that point I gave up with a 3B being in a troopcarrier, especially in America. I was just done.
So the “3 cyl 3B” was my 2nd engine, still don’t know how it failed but it started knocking, took the head off and saw 1 wet cylinder. My guess is it lost compression, for some reason or another that’s why it wasn’t firing. Wether that’s related to the bottom end knocking I don’t know
I wasn’t near any water, just driving around my home town going 35mph with the 2nd engine when it started to knock
Thank you for all the info, this will be great to compare and be able to mix and match to. I haven’t checked the flywheel size, figured it was all universal. If it is 300mm that’s a great idea, a Frankenstein of parts all together!
Will get better images later, pistons have some scoring on them but some of my cylinders still have the cross hatching in them!
Last night my buddies and I had a fire out on the beach, put the crankshaft in for an hour or so. Looked awesome.
