The Dark Wob

(If the Mazda grenades I'm buying a Jag).

What made you do a compression test?

Bad running and suspected something wrong? Or just being inquisitive?

What did it improve to?

If the car wasn't expensive I'd just run it until the engine fails, then lob another (compression-tested) engine from a breakers into it. As has already been said, they are cheap & plentiful as rust usually kills MX-5s.

I certainly wouldn't bother tearing the engine down to re-lap a valve or two. Not unless I really had to.

WHY DID YOU DO A COMPRESSION TEST AND MENTION VALVE STEM SEALS?

Probably because he was misinformed by somebody, and doesn't yet have the experience to know better?

One way or the other, it doesn't really matter.

You're confused? think of the poor youngster who buys a sportscar but gets it with a junkman gearbox.

Possibly not half as confused as the lady in the passenger seat who discovers young ghosty has a free hand whilst changing gears!

And that Mr rover is why autos are great fun. Don't have to move her head out the way to change gear.
