 | CAUSE:
If you have found this site, you are probably aware of the problem some of the Vauxhall C20XE and C20LET GM heads suffer from, commonly known as the `porous head`. The following pages will hopefully help you understand the problem and possible fixes.
Cause - Click to read up about one of the most common cause of `mayo in the water` on the C20XE and C20LET engines and the misconception that is the porous head.
FIXES:
Outlined are two guides which will help you understand how to fix the problem of the `porous head`.
Solid Tubing - Click to gain an insight on how to use a solid tubular bar to solve the problem.
Hollow Sleeving - Click to gain an insight on how to use a hollow tubular sleeve to solve the problem.
Pipe Size - As a guide the size of pipe which a few people have reported using is: 8mm in diameter and 87mm in length. I would sugest using an aliminium tube where possible so there is no cross metal corrosion, and no warping due to different expansion rates. See the visitors section for links to sites which maybe using / detailing the fix.
