high oil consumption per gm manual. car under warranty for a bit longer. diagnosis not covered. diagnosis estimate 800 bucks from non-gm local/small eng shop. performing leakage test also while spark plugs are removed.need to find tdc of cylinder #1. worked on recips in school we had a tdc peg. you find compression stroke, turn eng till piston hits tdc peg that was screwed into sparkplug hole and bam tdc of first cylinder in firing order. use degree wheel from there to get tdc of all pistons. dont make em for gm from what i found. they make generics, some people make their own. but only a true peg made for that engine is dead on. since gm doesnt make em, since the dealer was like wtf when i asked on the phone (that would be parts clerk and service tech) there must be another way. several online forums, etc. say about markings but i have seen none. have actual gm manufacturers maint. manuals to perform tasks. nothing stated about timing or how to achieve tdc with timing markings. only need to find tdc of cylinder #1 for sure. If the action i described in the 1st post (which im new so is under introduction cause i got no clue about this site yet) above is correct, obviously i have a problem. i am working on the vehicle to try and narrow down/diagnose myself as i cant afford pricy diagnosis or an iffy shot in the dark repair. boredom/learning plays a role as well.
