I bought this car with this tick and I am really wanting to fix it for good its annoying first of all second it cant be good. I have verified that it is the valve lifter lash making the noise.

I have also searched up and down and thank you for the good information i have already gained from here!

I have been messing with this car for a few days now and I have measured everything at least three times and checked my math several times. I have a pretty solid Honda background so i'm new to all this complicated quad cam timing chain stuff but i can manage that. My real issue is i have ab 8 lifters out of spec and they have been that way since i bought my car. 2 of the lifters i can get replacements for the rest are too big of gap i assume and they don't make them sooo what causes the larger gaps and how do i go about getting my car back on the road? I'm about to upload my spec sheets i have if that will help any.

the Attatchments are pretty self explanatory the first one is valve lash and lifter thickness the second one is my math to figure out my new lifter thickness.

Thanks for the help ahead of time. :thumbup:

 

Might want to post this in the engine/drive train section on my350z.com (not forced induction) to elicit more responses. There is a slightly more technical membership over there and the engines are the same.

 

Thank you I will do that next

 

no luck there either. sadly
