On cam-in-block engines, camshaft bearings support the camshaft and form part of the oil system. Incorrectly installed cam bearings can block oil passages or bind the camshaft.
Before Installation
- Clean the block and oil passages thoroughly after machining.
- Identify each bearing position. Cam bearings often differ in size and oil hole location.
- Inspect the cam bores for damage.
Installation
- Use a proper cam bearing installer to drive each bearing straight.
- Align oil holes with the block passages.
- Set the bearing depth as specified, especially at the front and rear.
After Installation
- Confirm oil holes are open with a light or wire.
- Lubricate and install the camshaft and check that it turns freely by hand.
- Install the rear cam plug with sealant.
