Lend me you ears

Yep I used to go no-go gauges, I have that exact set. And i verified with a standard set

And for some background I've been doing valve adjustments on many many other vehicles for 20 years. Primarily Land Rover diesels, airhead BMW motorcycles, and other early European cars.

First slant.

what really threw me off is how absolutely silent the car was when running prior to doing this. and that the valves were adjusted so tight I couldn't even fit the feeler gauge underneath of it before I did the adjustment.

This seems right it's just so much noisier than what it was! I do appreciate the insight
