Can you hone cam bearings?
Honing the ID’s of cam bearings to increase clearance is not recommended because hone grit may become embedded in bearing surfaces which will cause shaft wear. Bearing ID’s may be reamed, but the most practical means is to adjust camshaft journal diameters by grinding.
How easy should a camshaft spin?
A cam should spin freely with your fingers. I have installed tons of cams in many different engines and they all spin easily when correctly installed and lubed. There is a good chance you caught a bearing installing the cam scratching it, causing a high spot.
Do cam bearings affect oil pressure?
There are also passages in the camshaft for the cam bearings (that support the camshaft). Typically worn rod bearings, not main bearings or cam bearings, result in low oil pressure at idle. If the other bearings are worn, the pressure would be low no matter what the engine speed.
Should cam bearings be installed dry?
As a case in point, earlier small-block Chevy blocks might feature only an oil-feed hole that aligns with the main cap oil passage, in which case the cam bearing’s oil hole must align with the saddle’s oil hole. The cam bearings must feature a dry installation at the block’s cam bores.

Can you turn a cam by hand?
Should You Be Able To Turn The Crankshaft Pulley By Hand? It is normal to not be able to rotate either cam or crankshaft pulleys by hand. Then you would have a problem rotating them bare handed.

What makes cam bearings go bad?
They suffer from the same operational conditions as do crankshaft bearings: overloading, oil starvation, too thin minimum oil film, misalignment, and contaminated oil. The possible failures are also similar: material fatigue, excessive wear, seizure, and corrosion.
Can you replace cam bearings without removing crank?
Not possible, or desirable. The engine needs to be completely disassembled and the proper tools used.
What is camshaft bearing clearance?
Typical oil clearance of camshaft bearings is 0.0015-0.002” *D Where D – the bearing diameter.
