[euro911sc]

I purchased a Lonacre 73010 Leak Down tester. Longacre leak down instructions state to remove the rocker arms prior to doing the leak down test. I assume this is to ensure the valves are closed. This is not something I'm lookin forward to doing with the engine in the car... Ideally, I'd like not to mess with that stuf till I get the engine out.

If I am running a euro SC stock cam do I still have to remove the rockers? At BDC, prior to the compression stroke, both valves are closed, correct? Could I simply loosen the valve tappets all the way instead? Sounds a lot easier...

Just to check, from TDC, BDC prior to compression is 1.5 rev (540 deg) or so?

Thanks!
