hi guys, not too long ago I started experiencing a weird idle issues, this came right after adjusting the valves, it doesn't bounce off idle like it would if it was an icv problem, it idles like if it was a cammed V8, the idle is straight a 600 rpm, no problem at all there, and just off idle it revs perfectly smooth and has lots of power up to redline. now i didn't adjust the valve myself, i did it with an old mechanic that had worked on old bmw's all his life, we changed all that is required when removing the cover, valve cover gasket and the 4 rubber thigny at each end of the head. now two things, he told me he adjusted the valves a tad tighter than specs to compensate for the wear of the engine, and it is not the valve cover that was on there before, it is one i sandblasted and painted. i am a little concerned it might of been warped (if thats even possible) and letting air go into the valve train while the engine is running, i would've tried putting my other one back on but i dont have access to it at the moment. i have looked around forums and youtube trying to find something similar but can seem to find anything, has anybody ever experienced this problem? i am quite confused as to what could've caused this after a simple valve adjustment, it was running perfectly fine the day before.

you didnt adjust your valves correctly.
the engine must be dead cold
.01" feeler gauge
measured under the eccentric - top of valve
should be snug to pull in and out the feeler when tight. but not hard or loose.
Much wow
I hate 4 doors

Just out of curiosity, how would the engine benefit from valves a bit tighter for the track? What advantages does it give!
