Just bought a b16 head, how can I tell if the valves is bent? Without removing the valve itself

Put the head on a bench with the valves facing to the side and pour water on each port. If the water comes out the valve seats most likely you have a nice bent valve.

So the port facing to the side or up??

Ports facing up.


Same thing, but this guy uses brake cleaner

do not put water in/on anything anywhere!!!!!! and that don't mean its bent. the valve seats may just need cleaning or a valve job may need to be done. people like you should not be this area of the forums!

do like the guy said above with the brake cleaner.

Actually, that's how I've tested a few heads. I used WD40, not water though. A proper seal may drip, but a bent valve will gush out, even if it's bent just a tad.

Recently went with my neighbor so he could get heads for his shit bucket. Guys got pissed when I broke out a can of brake clean and did the same thing. Kept saying the head was good, 2 bent valves later, heads went from 200.00 down to 50.00, took em to the machine shop, had em checked for true, replaced the vlves and hes good to go.
