Power Problems
PISTON AND ROD ASSEMBLY
There are a number of power related problems including excessive oil consumption, smoke, blow-by and poor performance that can be caused by
inadequate sealing between the piston rings and the cylinder walls. A blowby measurement can help detect the problem.
Verification of the damaged or worn component requires visual/dimensional inspection of rings, pistons and cylinder walls.
The cause of piston ring wear can range from wear over a long period of service to a dust-out in a short period of time because of poor
maintenance of the air intake system.
