Are these valves bent (very, very slow leak)?

1999 EJ22 broken timing belt:

 

A couple of valves on one head slowly seep water, very slowly it gets wet around the valve edge, then very slowly gathers and drips after awhile. Can't see the water level decreasing after a couple minutes. It would take hours for it to leak the water out of the ports.

 

That doesn't sound like bent valves which normally flow water, but I'm not very well versed in valves.

 

Is that simple wear or bent valves?

 

One head has two bent exhaust valves, rest have no leak at all when ports are filled with water.

 

Second head has two bent intake valves and the other seepers mentioned above.

 

*** Normally I'd do them all, that's all I've ever done, but at $20 each I'm not interested in that on this particular vehicle/motor.

john from ky said to just lap those valves in when i lap the new ones in and he bets they hold just fine.

 

given all the "seepers" were on one head i'm wondering if something caused that? seemed like valves were adjusted and not causing them to hang.

 

sounds like a plan.

Probably just cruddy seats. Is it the exhaust valves that seep? Might be from a rich fuel mixture or coolant contamination fouling up the seats enough to leak just a little bit. It's probably something that happens all the time, but if you have the head apart might as well lap them while you're at it.

I think it was.

sold, will do.

 

thanks for the vote of confidence, first time doing this valve lapping stuff.
