My 1932 did run pretty ok, but began to loose water at each trip, so I did some testing including compression test, which showed lower values on cylinder 4 & 5.
I then did a leakdown test, and could see bubbles in radiator when testing cylinder 4 & 5.
I decided to overhaul engine, so I removed engine from the car.
I removed the head, and could see there were blow through from cylinder 4 & 5 to waterchannel, and also beginning around cylinder 2 & 3.
Head is now at engine shop and will have a crack repaired, machined flat including manifold surfaces, and exhaust seats will be machined or replaced.
I now want to check my main and rod bearings.
When I look through old threads and in manuals, I can see that best way to check bearings are by removing shims until engine is binding, and then reinstall shims.
I only have shims in 1 rod, what is then the best way to check bearings?
For the mains I plan to use Plastigage to get an indication of clearance, is this the best way, or can I for the test put a shim behind the bearing shell?
Rods can be slightly moved sideways by hand, but can`t feel any slap when I lift in the rods, any good ways to check clearance?
I didn`t have any knocking sounds when driving, so think bearings are ok, but at the very end of their lifetime.
For now I hope just to do an overhaul and get the last miles out of it, and then do an rebuild in some years.
