[QUOTE="ctgreddy, post: 14265075, member: 122280"] ^ His results are not normal tho. Most higher mileage cars will be off by a decent amount but not like that, like some will be 165 some will be 150. Not everything within 5psi yet one bank being 30psi more. That to me means something is off. Very well could be timing even tho it seems highly unlikely that it's jumped but hasn't jumped enough to mess anything up. I'd do a leak down on it next. That'll tell you if anything else is at play, wether that be head gaskets, rings/pistons, valves, etc. if it passes all that then I'd start looking into the timing idea. [/QUOTE]
