Tappet clearance

[les]

I’m going to adjust my vans tappets to 12 thou, some sources suggest 15 for exhaust, why would this be? I’ve never had any issues with the factory settings. I would imagine 15 would make a racket, which I wouldn’t want.

Thanks should have done a search first ——- I’ll do a loose 12 thou I think.

Probably as well you didn't search for it - along with claiming that coils were never at fault, it was one of Roy Allingham's favourite topics. I suspect you'd still be reading the posts now

I'd say it's worth it if you use the car 'hard' - I do quite a few motorway miles in mine and it's also pepped up so I've always used 15 thou on the exhaust valves. It isn't too noisy

He he - always a subject of debate with Roy! I have to say, like Les, I go for a 'loose' 12 thou.....and that after a conversation with a well-respected Minor enthusiast mechanic.....
