MG MGA - Valve Adjustment

Time to adjust the valves for the first time on my A

Set the engine up to check valve #1 (valve #8 open) and their isn't currently any gap.

Checked another valve, no gap

My had casting number is 565394 should my gap still be .017"?

Yes. No gap is bad, bad, bad, leading to loss of compression and burned valves.

Russell - The tag on my engine (1622cc)says 15 when hot. I would expect you have a lot of noise - valve "clatter" - correct?

Ken, Russel,

If the gaps are too small, that can make the engine very quiet, especially on tickover. A slight tappet rattle on a B series engine is quite normal.
