Common Cat C12 Problems: Ultimate Guide

One of the most common Cat C12 problems is its head gasket. This problem occurs in all types of engines but is more likely in the C12 because it is designed to handle higher power and constant heavy loads. Other common Cat C12 problems include water pump issues, thin cylinder head, and o-rings in cylinder lines. In addition, a Cat C12’s head gasket may become damaged sooner than it should, leading to a contaminated oil.

Lifter & roller problems

Caterpillar C12 lifter & roller problems are fairly common, and typically begin with a small bushing in the lifter. If the problem continues, it could damage the camshaft, which is more costly. These problems are not a design flaw, but they do tend to happen more after 500,000 miles. The following are some possible causes and remedies. Listed below are some common problems.

Head gasket issues

When it comes to Cat C12 engine repair, it’s worth mentioning that head gasket problems are quite common.

Other common Cat C12 engine problems include coolant contamination, thin cylinder heads, and problems with the water pump. Below are some of the most common problems.

A failed head gasket can cause your engine to overheat and damage the cylinder and engine block. If you’re driving with a failed head gasket, you’ll need to tow the car to a repair shop right away. While a bad head gasket is not a big deal at first, you’ll notice symptoms as the leak enters the engine’s oil and coolant passages.

92K GCVW is too heavy for a cat c12

The 92K GCVW on my C12 makes it a little heavy for a C-12. It will need an overhaul after 500k miles. It would also need to be rebuilt every time I remove the head. The C-12 is too heavy to drive this way. I would recommend a smaller cicada. It is also not worth the cost to overhaul the engine.
