Frequently Asked Questions

How many valves does the engine use?

There are 12 valves: 6 intake valves and 6 exhaust valves.

How do I know an exhaust valve is bad?

Compression loss with the leak-down escaping out the exhaust points to a burned exhaust valve - they run hottest and burn first. This is diagnosed during head work.

Any tips for fitting the valve?

Fit exhaust valves with a fresh seat cut and lap during head work, since they run hottest, then set the valve clearances to spec.
