I installed a set of full 1.6 roller rockers in my 36K mile L98 about 6 weeks ago. Ever since I have noticed that they get noisy (ticking) in the 1800 to 2000 rpm range. I've gone back and re-adjusted them 3 times now. The last time I did them while running...you know...back off the retaining nut till they start to clack, adjust to where the clacking just stops then tighten half a turn and set the lock nut. The only thing I have accomplished is the move the ticking into the 2000 to 2200 range.
The car runs exceptionally well with a smooth idle. I expected to get a little more valve noise with the RR's but this condition at RPM concerns me. Above and below this RPM range they are quiet. I don't think it's a lifter problem because it should just be one or two making noise. This sounds like the whole bunch.
My question is...is this normal (can't imagine)
Could all my lifters be a problem? (unlike likely at this low mileage, on a very clean engine with no varish build up)
Could the rockers be out of spec? (possible..they are an off brand)
Any other ideas?
Thanks
