Just noticed my CAT, 2HP, 10 gal tank was losing pressure after sitting for a while.This compressor is used for my Altaros booster. I just thought it had a small leak, so i checked every connection, When i couldn't find any leaks i decided to remove the manifold. I don't have pics, but believe me, this was a mess. It was full of rust on both the springs. I cleaned & lubed everything up & it's holding air fine now, but you bet i will be checking my manifold more often now! CAT compressors does have a nice site where you can order parts, so that helps.
