Always make me nervous when Gregg [scooterG] makes sense.
.. and they admitted their mistake which is huge. That said, I'm not happy about the valve shims either. I'd always have that on my mind..... but they did look for and find what was wrong, so I applaud them quite a lot for that.
Great idea, but then we'd just wonder if redzg was just appeasing us. I'd think it preferable to be labeled Obsession Gifted though, not OC.I know that it would drive me crazy thinking about what was going on under that valve cover. But then, I checked my valves only 5,000 miles after adjusting all of them. Maybe if redzgrider just tells us that he checked them, then we would all shut up and the OC members could get back to cleaning and organizing their tools, with supporting documentation, of course.
Hmm-not likely that there was much carbon buildup.... but if they screwed up the clearance on just one valve,holding it open or not opening at all,it would run like sheeit...Yeah, yeah... I get it. I'm obsessive compulsive about these kind of details. But here's why I think it could be important in this circumstance: The shop claims the clearances were found to be too large. Experience and collective data shows that the valves on this engine wear in a way that reduces the clearances, not increases them. So the most likely reason for increasing clearances would be carbon buildup on the faces of the seats and valves not allowing them to seat coeectly.
If they have changed the shims by a large amount and then the buildup later burns off the result could be some acutely tight clearances, which as we all know is what we are striving to avoid in this whole valve check/adjust thing. If the shim changes they made were small, or had they erred and measured them too tight and then added too much clearance, it would be less worrisome.
