I have put about 75 miles on the SBC 350 that I rebuilt. I have noticed a bit of blue smoke on startup and suspect that it is the teflon comp cams positive stop valve seals that I installed. I am planning on removing these and replacing them with the viton positive stop seals instead. I have also read quite a few threads that have mentioned using the positive stop seals on the intake valves and umbrella seals on the exhaust valves. Is there any particular reason why you shouldn't run the viton positive stop seals on all valves?
When I originally installed the valve springs I used a rented compressor from Autozone which was a piece of junk and very frustrating. I have been looking at this type of compressor manley spring compressor
and am wondering if it will work for occasional use. Does this tool provide enough leverage to easily compress the spring?
