Adjusted my valves 14mm not 15mm wrench used.

[Ben's Z]

In the book that came with the car it said the adjustment nut was 15mm, and I saw that somewhere else, however my adjustment nut was 14mm. However the other nut I loosened was 17mm. Was something changed on my car in the past do you think?

As far as the adjustment goes most of the exhaust valves were too tight. I believe it said .012 in the manual. I made sure that when done that .014 and .010 would not fit. On the intake valves I made sure .006 and .010 would not fit after I felt a slight drag on .008 I hope all it well. This was cold and I have not put on the valve cover as I am wet sanding the valve cover to polish it later today.

14mm/17mm is correct.

I prefer single blade feeler gauges in single increments (others like the stepped blades)

Hot intake= .009 loose/ .010 drag/ .011 won't go

exhaust= .011 loose/ .012 drag/ .013 won't go

Cold:

Intake .008

Exhaust .010

Hot:

Intake .010

Exhaust .012

Willoughby Z is correct, Ben.
