I have had a lifter noise for some time now but finally got around to taking the valve covers of but nothing that i can see seems to be causing it. Anyone ever had any lifter problems. I have a 2004 350z with 117,000 miles. Are the lifters solid or hydraulic?

 

Is it a clicking sound from the engine?

 

yeah it is def coming from the valve train.

 

what oil filter are you using

 

follow service manual instructions for checking valve lash,you don't have lifters in a vq.the cams act directly on valve,different thickness buckets determine lash.

 

Those buckets are called lifters

to the op. get a feeler gauge and check the clearances. Refer to Service manual for specs

 

what do they lift?

 

they are not called lifters. they are called buckets. or bucket tappets I think.

lifters are different.

 

Hmm I have the same noise also but don't have knowledge or tools to fix this.
Would the dealer warranty this?
Sorry for the thread jack

 

you actually have to take out the cam and install a thicker bucket and check the clearance. The service manual will tell you what clearances you're supposed to have.
Its a PAIN in the @$$ to do.

 

you do have to pull cams to adjust,but not to check.you actually need cams in to check.you might only need to change a bucket or two,so check and do the math.to determine what you need compare to service chart.bucket # is underside of bucket so expect some down time unless shop you go to has spares saved up.

 

I know Jeremy from Performance Factory keeps plenty of them around.
