Bent valve: How to check for it?

[MunichTaxi]

Recently, the timing chain jumped 3 teeth on my M130.92 (6 cyl.) engine.

I put in a new timing chain today, and the engine turns freely with a socket on the crank. #1 TDC matches the camshaft mark. All valve springs are compressing as normal.

Seems that I should do a compression check for each cylinder next. Of course, that means using the starter.

Is there any other method to check for a bent valve that I should do first?

if one of them has way too much clearance, indicating that the bent head is preventing it from closing fully.

PS: This assumes that the clearances have been properly maintained before the timing chain problem.

azzuming that you suspect a bent valve due to contact with a piston---check for excessive clearance on all by turning over by hand--- any valves hung open should be obvious. If none appear open and you still suspect any are off slightly do a compression check to confirm-- you have the timing set per spec, the damage is done don't worry about using the starter.
good luck, James

I fiqured that the next thing to do. I just wasn't sure if there was another method to try first. As Fishslayer said "Any damge is already done".
