help! bm owners

I am checking my cylinder heads, NOW! Clymer says the valves cannot be
ground.

Don't know if I need to, but I need to know!

Both look smooth, in & ex, ie uninterrupted contact all round.

Inlet is metal coloured , exhaust is black coloured.

<40K and generally good nick.

Erm, I'll wait for an answer.

TIA UKRM!

 

HBOL sas you can, as per normal valves

Just another BOL really. Better than Haynes, but still a BOL.

Less than 40k and you've stripped a BMW engine? I'm not surprised you
haven't found anything wrong.

I'd just get some fine grinding paste and do a few spins only per valve.

Tum-tee-tum-tee-tum-tum..........

So why would you?
If there is no pitting and no leaks through if you fill the combustion
chamber with paraffin don't worry. Some boxers have a dodgy welded 2 piece
exhaust valve thats worth replacing at 40k mind.

 

All hail UKRM, I'm off to the garage.

Take careful note of that advice!

So how do I recognise these dodgy exhaust valves?

Sounds like someone's speaking from painful experience.

I think it affects boxers of a certain age )
