Be sure to have the cam bearings replaced. That is the one thing that cannot be replaced with a “in frame” overhaul.
Pulling the engine is always the best way. I grew up working at my Dad’s mechanic shop and he was one of the type that believed in rebuilding the engine in the vehicle. I definitely do not miss those days!
Now it is on a stand I'll probably do a complete overhaul. Right now dealing with "interference". Christmas and visiting relatives interfering with garage time.
Back at my engine at last. Very strange but finding engine in pretty good shape. In another post it was determined engine is a 1960 223 car engine. Nothing indicates engine has ever been apart. Standard rod bearings in good shape with 1960 dates. No ridge in cylinders except a little carbon in top. No oversize numbers on rod caps, pistons, etc. Have to mic everything yet. Timing chain completely worn out. I could almost lift chain off gears so it has plenty of miles. So far it looks like I can avoid the machine shop.
Have not pulled the crankshaft yet. Rod bearings look good. Got diverted again but hopefully back to it soon.
timing chain looks like how I feel sometimes.
Growing up helping at my Dad’s auto shop I can relate to that. I can remember removing valve covers and it looked like a solid mass where you could not see the rocker arms. And then under the intake manifold removing the sludge by the hand full!
On the plus side, I finally justified buying the parts washer I always wanted. I changed the oil and cartridge filter way back when I bought the truck. Poor thing only ran a few times each year hauling tree branches to my burn pile and a few days every few months hauling blow sand back to the dry river a half mile away. Should have done it annually I guess.
No copper showing on the crank bearings? They really did use better material to cast these things.
Ok, pulled the crankshaft. Bottom half of rear main lots of copper. Other bearings tiny bit of copper showing on edges. Camshaft needs replacing though. Pitted and a couple of lobes worn. Adding up fast. Complete kits are starting at $900. Starting to wish I would have found a 292.
I think the inline 6's run nice and smooth! Had one in my Comet before switching to more power but it got 25-28 MPG with 3 on the tree (289 with C4 only provides 18-20MPG). Are you too far along to do a good cost analysis on keeping the 6 vs going 292?
Yes. I found through Cleggs a complete kit for the 223. Since I don't need pistons it lowered price to $750, no tax, free shipping. If it was a truck for the highway the 292 would be my first choice. For this old dump truck, the six will be fine. I am amazed it ran at all. Low compression, burned valve, one cam lobe worn round, timing chain shot. If I get the whopping 139 hp back it will feel like a rocket. A friend saw an ad for running 292 for $500. I would want to go through it too while out of truck so would be out lots more, I think.
