I'm replacing a pair of exhaust valves because the previous owner was negligent with oil changes and allowed one of the valves to burn. I've already got the head off of the car and am confident I can do the procedure myself.

Originally I wanted to get some Honda valves, but apparently Honda has discontinued replacement valves for the D15B7 engine. There appears to be a few different aftermarket valves available that would fit my engine, but I don't know which ones are trustworthy.

Does anyone have any experience with the following brands? Does the brand even matter?

Dokuro
DNJ
Enginetech
Supertech

Thanks guys!

 

What are your goals? For the most part, it would be easier and cheaper to just buy another good cylinder head, maybe upgrade to a vtec head.

 

^^good advice

 

Thanks for the replies guys. I looked into doing maybe a mini-me swap, or just get a new head. I'll have to check around at junkyards for a new head, but in Maine most cars older than 20 years old just get crushed due to the rust so I'm not sure how much luck I'll have.

My goals are pretty much just to make the engine run without burning oil. The engine only has 104k on it, and I'd like to use the car as a daily driver once the project is completed.

 

If you are just trying to get it running again, then getting another head would be best. Any D15 or D16 head will work, so whatever you can find for a good price, and in good condition will work

 

Is there anything necessarily wrong with installing a pair of new exhaust valves on the burning cylinder? I would spin the new valves in the head with a suction cup and some lapping compound to get a good valve seat.

Maybe what you're thinking is that there's something wrong with the head that burns valves? I'm worried about that too, but I'm 99% confident that this burned valve happened because the previous owner never changed the oil and never got the engine hot. It was a daily driver for an elderly man who used it on a 7 mile round-trip journey every day. The inside of the crank case is nasty. Old oil gunk on everything. And there's a HUGE amount of carbon stuck to the head.

I'm still gonna call around because it's better to be safe than sorry, however there's a pretty big appeal to me that 2 new valves cost $30, and a full set of exhaust valves is $80. I have to buy the rest of the stuff (head gasket, valve seals, water pump, ect.) new head or not anyways.
