My motor is a 1911 I got used. It has a carb cam of unknown spec. It runs pretty good. The valve adjusters are a swivel foot style adjuster and the top of the adjuster whacks the inside of the valve cover. This does two things. First, it eventually breaks a hole in the cover. Second, the tapping causes the valve cover to lift ever so slightly from the head, allowing the gasket to buckle a little and leak oil.
I assume I could swap out the adjusters with stock ones or I can cut the adjusters to make them a smidge shorter and re-tap them to make sure I can still use them. I was wondering if there is an option for a taller valve cover of some sort? I've seen screw on covers, but I am not sure how those work or if they provide any more clearance. Here is a picture of a busted valve cover from the last time this happened.  TIA |

yes balance matters.
BUT its alot better to have a screw that is 1/5 a gram off then to have a hole in your valve cover... If you measure the screws prior to cutting, you should be able to get damn close to the same size. Leave some extra material sticking out that you can grind off the sides if you decide to balance them... I bet you could buy pre-made , pre-cut, pre-balanced screws from Jake is you ask nice. Rich |
