Ok, I haven't done a valve adjustment since I bought the car which was roughly 9 months ago. I purchased it from someone who had been working on it and it was in pretty good shape. Today I go to adjust the valves and when I lift the valve cover, I notice the Pivot lock nuts are much bigger than any manual said they should be. I haven't been able to find an L28et that looks similar to mine with the cover off. Maybe I'm not looking at it right but I thought I would ask before I started loosening the nuts. Also there aren't two nuts like the manual says, just that one lock nut.
I also tried to get the feeler gauges through just to see If there was any clearance. and I couldn't get even the 0.0015" feeler through with the cam lobe pointing straight up. Is there something I'm missing?
(another note: The lock nut on there is bigger than 22mm, which was the biggest wrench I had on hand)
