[QUOTE="TripperMike, post: 1247736, member: 27241"] Raising this thread from the dead because it had good info for me in my hour of need. Just did the clearance check today and bear this facts in mind: Old Yellow has 190K on the clock, last valve check was nearly 3 yrs and 60K miles ago, and so far only one shim has ever needed to be replaced and that was at around the 75K mark. My findings today: I1/I2 .18/.20 .19/.19 .18/.17 .20/.18 E1/E2 .23/.24 .25/.23 .23/.20 .25/.20 So my concern was that even though they were all in spec., I was concerned about those three exhaust side valves being at the very edge (.25 (2) & .24 (1)). I was relieved when I read Ionbeam's post. I wasn't really looking forward to pulling out shims and switching. It's a big enough PIA as it is just to reinstall the valve cover alone. I gotta say I am amazed. 190K and only one shim replacement. [/QUOTE]
