2) it is not safe to assume that;) does snowbum have a long, wordy article about it? re-read it a few times OR find yourself some local airheads (I did). It is not complicated, but you want to be sure you have measured everything appropriately and add/subtract shims as required. the danger is not having correct oil pressure.
Thanks! I'll take another look at Snowbum's article and break out the calipers for the oil filter cylinder measurements. Do you have a picture by chance of what the shims look like and where they go?
ETA: Nevermind, I found this: http://www.largiader.com/tech/filters/canister.html
My canister definitely has the sharp edge, and no shim was installed when I removed the filter. Where are these shims available?
