I think I developed a lifter tick on #1. this started a few k mi after I switched to gold GC with LC20. engine was whisper quiet before.
how do you fix a noisy lifter - adjust valve clearance?
will this cause excessive wear if not corrected?

 

I doubt its your valve ticking...

 

not sure I understand your reply... isn't valve clearance the play between the rocker arm and the valve stem when the cam lobe is not acting on the lifter -- if there's too much play the system makes noise, a "tick", right? if not, then where is the noise coming from.

 

Injectors make that noise.."tick" Ive heard soo many maxima's that tick.....check them

yeah my injectors make that tick - but this is something different. a little bit lower pitch, slower, and more metallic than injector noise. and it seems like it's coming from inside the head cover as opposed to on top/center where the injectors are.

on a side note - is the injector tick a bad thing? I always thought it was normal.

thanks for the replies.

 

There are no rockers in your engine.
The cam lobe acts directly on a bucket style lifter that sits right on the end of the valve. Valve clearance in a VQ30 is adjusted through changing lifter shims. In a VQ35, you change the actual lifter.

 

Exactly...

 

Crikey, just the same as on my 1958 XK-150SSS Jag. Hope I never have to do the adjustment.... argh. I hope the cause is not breakup of the surface of the cam lobe. I don't know if the Max uses a surface or case-hardened shaft or the whole shaft is of tool steel. Surface hardened sometimes fails.

 

all nissans have that tick.......its normal/////giggity giggity

 

the injector tick is nothing to worry about, a little fuel power quiets but doesnt silence mine...

 

If you drove a 3rd gen with the VTC's clacking a little tick wouldn't even get noticed. Those VE's run like a mofus though.
