Tim you cannot really use plastigage like we use lead wire it does not really lend itself to being removed/peeled off and then measured with calipers/mic's. Seems to me the width method is well calibrated and accurate enough for the required tolerances on this sort of application. I have often pondered screwing around with lead wire and calibrating by width in the same way.

Why would you want to go tighter you need some clearance. If the bearings look good then with figures like those there is no need to spend the money.

Tim FYI I use lead wire used for fly tying it comes in different sizes 10 - 35 thou and saves on buggering around with one size.

Plastigage is mesured by crush width not height.

if you have a uniformly round rod and crush it it won't matter if you measure height or width. The ratio of squish will be the same. Plastiguage is just way easier to measure the width then the height.

On Duetz Diesel you use lead solder ontop of the piston to check clearence to head. Head's get shimmed on them. The lead solder worked fine.
