Timing Chain & Rough Idle...Cause and Effect?
Forum, Sanity check please.....after having head work done, I suspect the mechanic replaced the timimg chain 1-2 links off the cam sprockets which has resulted in a rough idle. Does this make sense as to cause? I've eliminated everything else (I think). How do I test/check this? Valve clearance at TDC? Which cylinder valve? What should measurement be. TIA for your help!
