Need Help R34 2.0L Non Turbo Making Loud Ticking Noise After 2000 Revs From Head Around Cylinder 6

[ei2hrb]

Hi I just bought a r34 non turbo and it has a loud rattling noise after 2000 revs and a miss fire on cylinder 6 so she is ticking over a bit rough. Anyone got any idea what could be wrong with it have looked around the forums a bit but haven't really found an answer. I was thinking it was a lifter that was stuck but from what I read they are solid lifters so I see that the Neo engines have vtc solen ides on the intake valves could it have something to do with this and how would I check etc any help would be great full or is there shims on the lifters that might have been thrown off the lifter just find it rather strange that there is no noise when ticking over just the rough idle hope fully 1 of ye can help me cheers

have you checked the clearances in your valves ? can cause excessive ticking

No haven't done any thing yet wanted to see if anyone had a similar prob before I go stripping it down

Starting to think its prob a bent valve gonna do a compression test maybe later will have a better idea then
