M50 '92 Valve Job - Any advice?
I may have bent a valve at my last track event. I've got a 92 325is 279,000 miles. The compression on #2 cylinder is 0! The others are all 210-220 ft/lb The car still runs OK, but you can tell there is a problem. No smoke at all, but the exhaust smells rich.
Has anyone done a valve job on this head and had anything interesting come up?
Is there anything I should have done when I get the head worked? I was planning to replace the valves in the bad cylinder, but if the others look good I was just going to have them cleaned up. I will replace the timing chain(s) regardless.
Any performance mods I should consider? Better springs, etc.
I will pull the head myself, but I am going to have someone do the work to it.
Any advice would be appreciated.
