Rattle
 

Just developed a harsh rattle on 87 560sel just after changing starter, which I do not think has anything to do with it,

probably timing chain, 243000, never changed as far as I know.

Compression 150-165 all aroud but does have a miss as idle.

?? Would I have this compression if the chain "jumped' and bent a valve??

Thanks

If you had a bent valve that was causing a miss you would be low on compression on that cylinder, I believe. Those numbers do not look at all low to me.

Change the timing chain, tensioner and guide rail irght away, it is waaaaay past due, you are running on borrowed time
