Hello community, I checked valve clearences on MY06 350z RevUp, intake valves are 0.28-0.30mm all of them, exhaust valves are between 0.40-0.45mm, car has problems like slow acceleration, high fuel consumption, is this because of out of spec exhaust valve clearences? cause I checked everything and didnt found any abnormal situation, Thanks in advance

The High End Clearance Ex Lash is .416mm. (.016") this is on a brand new motor.
The difference is so very very tiny. less than .0015" thousandths of an Inch
NO.......This Will Not cause or change high fuel consumption. and I doubt you could feel a change in power because of this. You would hear excessive Noise before a loss in power.
Stock Motor?
How many miles on Motor?
How about maintenence?

No, the Value Clearance you have is fine with a motor of 100k, this is NOT the problem.
It could be so many things......
Have you done,
New Spark Plugs?
Before & After New timing chain & tensioners, was there any difference?
Does the Motor Run Smooth?

100k miles, stock motor, new timing chain & tensioners installed. So I feel that car is choking, 100-100kmh is about 15.5-16 sec, before it was between high 13s to 14, I dont know what else to blame, I really need to know if it’s valve clearences will take care of it, thank you

yeah it was running smooth after changing timing components. this started happening two weeks ago, fsm mentioning 0.29-0.37 for exhaust valve clearence, it’s 0.40-0.42-0.45 and it’s not affecting power band? btw spark plugs is the good mention, I didn’t changed yet, therefore I have them in the garage and will install this weekend

P.S car is uprev flashed, I am self tuning. however I see lot of knocks, did also leakdown test and in all cylinders is only 5-8% loss, changed MAF sensor, absolutely no codes. when logging IVT,EVTs are good too. its even knocking when I hit gas pedal on stationary position, when its cold I hear slight ticking noise, when coolant goes to 70-80 there is no ticking noise, I hope its helpful information
