I was contacted the other day by a fellow soldier here in Germany. He has a 2005 GT with 115k miles on it and it is currently in the shop.
It seems that they tore into his engine and found that on cylinder #3 he has a lash adjuster that collapsed and there is excessive wear on the rocker arm (cam follower) and some scarring on the cam itself. He is asking for my help to replace the lash adjuster and rocker arm, which he has decided to do all the lash adjusters and rocker arms because of the mileage. But I want to address the real issue. It sounds like there wasn't any oil getting up to the cam on that lobe or to the rocker. Any ideas what would cause that? If the lash adjuster collapsed would it not line up right to squirt the oil up through the hole at the top of it? I doubt it is an oil pressure issue because there is no wear on anything else, and no check engine lights. Any suggestions on what could cause the oiling issue or was the collapsing lash adjuster the cause of the oiling issue?
Thanks,
