MARK 99STS Posted July 18, 2005 Report Share Posted July 18, 2005 Ok. Here is the latest on my engine. There is a spoke(Guru?) on the very back cam that rides higher than the lobes. We didn't see it before as it must have been down when we took the cover off the first time and that is what carved a groove into the valve cover. It rides higher than the lobes. The groove was right in the baffle for the PVC so the shop that screwed it up welded the groove in the cover, but the tolerance must be very close. All the caps were removed and inspected and appeared fine. As Guru said they apparently can take some abuse. After the caps were torqued down properly and the cover replaced, when we fired it up we still heard a noise. The peformance shop said it is just touching the weld that they did. Sure enough when we took the cover off you could see where the spoke was just hitting the weld. We ground it down, put the cover back on and it makes no noise and runs fine. We flushed it with new oil, changed the oil and filter and it now seems to run fine. I have no grounds to demand a new motor as I can't prove there is anything wrong with this one as they did fix it and cooperated fully. My concern is the longevity of the motor given the stress it has gone thru. It runs great now but I guess it is impossible to know what the long term effects will be if any and as I said I have no justification to demand any thing else as it appears to be fine. In talking to three different Cadillac techs at three different dealers, they all said the same thing. " If it is going to go it will happen right away otherwise it will be fine". Guru, any comments?
