Hi all: Someone recently posted the following link http://home.hiwaay.net/~langford/corvair/valvejob.html which details, among other things, setting the Compression Ratio (CR) of a Corvair engine. It's a pretty good write-up and very pertinent to folks who work on VW engines. However, about 3/4ths of the way down the page there's a picture of a setup, which employs a dial gauge, that the author used to determine deck height, but he doesn't describe *how* this setup is used. When I've measured deck height on the Vanagon engines I've rebuilt I've used a dial gauge to get the piston to TDC, then used a straightedge and feeler gauges to determine deck height. I've often wondered if there was some way I could use the dial gauge to directly measure deck height, but haven't figured out how. Do you think the author is merely using the flat bar across the top of the cylinder as a straightedge, to be used with feeler gauges? Or is there some way, using the pictured setup, that you can use the dial gauge to determine TDC *and* deck height? TIA. --------------------------------------------------------------- Tom Young '81 Vanagon Lafayette, CA 94549 '82 Westfalia --------------------------------------------------------------- |
