For the 2nd time I tore into my air suspension compressor
The first time was for a piston ring replacement a la Bagpipin Andy. Got me working for a while but I could see the cylinder bore had some scoring and I was hoping for the best, but it was not to be. Here is the scoring of the bore that I had going on and the piston ring fit very loosely at the opening of the bore.
The suspension codes just kept coming and I knew the piston ring fix wasn't holding things together.
So today I installed a $22 complete cylinder head replacement from China

I got some surprises in the amount of rust that had occurred inside the unit and how much less spring I have left in my unit.
Here is the new component cylinder head and the pieces that must be swapped over from the old one. Note the rust signature in the silver cover.
Cleared the codes and so far so good. A complete 25 mile drive without the suspension code being thrown.
My unit is a 2003 vintage (2002 build) and has 113K miles on it, so one might want to go the full monty of a cylinder head if you desire a more long term durable fix.
