I'm hoping someone can provide me with some insight on this one, as I'm now officially worried:
I was in the process of replacing the connecting rod bearings, and I had to rotate the crank by hand in order to get to the rods for cylinders 1 and 4 after completing cyls 2 and 3. When I went to do it, the crank was unbelieveably hard to rotate...even moreso than when I rotated it at the onset to start working. Whereas before I used both hands, this time it was 2 hands plus bracing my legs against something solid.
The spark plugs are pulled, the new bearings were lubed with assembly lube, and everything was torqued to spec (50ft-lbs on the rods, 65ft-lbs on the center main (pulled it to check for wear). The new bearings were a direct replacement (old ones were standard sized, new ones are as well).
Granted, I was on my back/under the car when I was turning the crank, and was probably a bit tired, but it seems to be <span style="font-weight: bold">a lot</span> harder than it was. Was it possible my uber-low oil pressure was being caused by loosened bottom end bits? Of the bearings I replaced, only 1 of the 4 I considered to really need replacing. The rest were in good shape, as was the crank.
Any input would be great, as I'm worried about trying to start the engine with it being as tight as it seems...
Thanks!
