how do you go about cleaning the valves and the surrounding area w/out removing them?

picture for refference

 

Best way would be to take it apart and have the valves and combustion chamber glass beaded... but you said you don't want to take it apart.
(thats what I used to do. clean and rebuild heads)

yeah i really don't want to. would carb/brake cleaner hurt?

 

I just realized I have my old D15B7 head in my shed.. I went to look at it again and saw the valves are filthy. I can't see how to even clean them . Just chipping it off seems to work. The stuff caked on it is so hard it feels like cement. Does yours feel like that?

i don't think so...its just has a lot of carbon build up all underneath. btw picture isnt mine, just using as a reference.

 

Yea you could use carb spray and a brush (WEAR SAFETY GLASSES! CARB SPRAY IN THE EYE SUCCCCKS!!) but you wont be able to get the buildup on the back side of the valve.

coo ill try that. how hard is it to remove the valves anyways?

 

You don't need to clean those. They're going to look like that 10 seconds after you start your car again.

 

You can try to Seafoam your motor and that might take a little off but i think Archidictus is right its just going to come back 10-15 seconds anfter you start the car
