recently had our timing chain replaced on a 2008 2.4l Malibu. last night the engine
would not start, took it back to shop and they told us there is no oil pressure and the cam shafts are not turning and all the intake vales stuck open. ruined engine. could these be related to the timing chain on this engine. not sure how the oil pump is driven, probably off of the crack shaft?
JA: How old is your oil pump? Has the check engine light come on?
Customer: the oil pump is original with 125000 miles, the engine light had come on and my son kept driving it for a week or so around town
JA: Are you fixing your Malibu yourself? What have you tried so far?
Customer: I have not tried anything yet, might trash the whole car as it is only worth $4500 - $5000. new/rebuilt motor will be to much. thought about trying to get one from salvage yard, don't know yet
JA: Anything else you want the mechanic to know before I connect you?
Customer: not that I can think of
