Another way to tell is to check the coolant. If the coolant is dirty or rusty, then you may have a cracked head.

How do you test for cracked head?

In order to test for a cracked head, a compression test or a leak down test can be performed. A compression test measures the amount of pressure that is able to build up in the cylinders of the engine. A leak down test involves hooking up a pressure gauge to the engine and checking for leaks in the head gasket.

How do you check cylinder heads?

Cylinder heads can be checked for warping, cracks, and other damage using a variety of methods. One common method is to place the cylinder head on a flat surface and measure the height of the head at various points. If the head is warped, the measurements will be different at different points. Cracks can be found using a magnifying glass or borescope. Another common method is to use a pressure tester to check for leaks.

Can you drive with a cracked cylinder head?

A cracked cylinder head can cause a number of problems with your vehicle. It can cause oil and coolant leaks, as well as engine misfires. If the cracks are severe enough, it can also cause the engine to seize. Therefore, it is not advisable to drive with a cracked cylinder head.
