Re: KA Laser firing order ? and other problems
As far back as I can remember, the Laser engine firing order has always been 1-3-4-2. Tappet clearences are a different issue altogether because these change for different year models, types of engines, and capacities.
You'll probably need to know what engine model you have before you can find any accurate info on it, say B series (B3, B5, B6) or E series (E3, E5) and so on.
About your last comment, a valve that is longer than what it should be will always be pushed by the camshaft (or tappet or whatever the case may be) and therefore will always be open. This causes your engine to loose compression because the inlet valves stay open when they should be closed and never have fresh air in the cylinder because it will suck from the exhaust as well as the inlet. You'll also loose a part of the fuel that's injected through the open exhaust valve and in a short time you'll burn the valve seats and faces. So, the noise you're hearing may be the normal combustion coming through the open valves. I think you should either repair that head properly or get a second hand one that's similar to the one you removed first. Your firing order is probably right but the car will never idle properly unless the valves are fixed. Hope this helps, cheers
