I tried posting this in another forum didnt get to much help.

I have a d15b7 motor that had spun bearings. I decided to rebuild bottom end. Everything was cleaned, installed, and replaced properly. There is no problem in the bottom end. While I waited for my parts to come in for the bottom end, I decided to take apart the head and clean it too. Took all the carbon build up off the vavles, vavles looked pretty good so I did not replace them, also put new vavle stem seals in, and cleaned all other parts very good and everything looked good. Put everything back together and started it up and immeditally noticed a tick. Figured it was kinda normal since everything was so clean and the engine is pretty much new. So I put about 700 miles on it changed the oil once already with a thicker oil but it still ticks, its a little bit more quite but its still really noticable.

I have researching on here for about a week now, did a valve adjustment 3 times and it still ticks. Its not the injectors its too loud to be that. I am also only getting about 20 miles to the gallon right now when I should be getting close to 40. I did the screwdriver trick to see where its comming from and its comming from the head. Also tried checking for exhaust leaks and I dont think I have one.

check out the video i made you can definitally here the ticking I am talking about

 

If you did the valve adj. 3x's, did you do the same clearance? If you did, try to go lower in your adj. For example, if you did .008-exh./.006-int., try .006-exh./.004-int.

 

sounds like it is coming from around the #4 area.....are you sure you out everything back together right and the clearances are correct for valve adjustment?

 

sohc have a tick anyways

 

ill try going lower in the adjustment sounds like a good idea.

 

I have the same problem with my D16a1, did you ever figure this out? If yes, what was the problem and the solution?

I'm wondering if it has anything to do with the timing?

 

Yes, timing and firing order goes w/ the adjustment of your valve clearances. If you have a service manual for your specific vehicle, look up Valve Clearance/Valve Lash adjustments, and also Ignition Timing. Hope this helps.

 

I am going to be working on the car today so hopefully this fixes it. Ill let you guys know.

 

well the ignition timming was off a little that is why i was getting horrible gas mileage

and i reset the vavle clearences again to .006 and .008 and it is so quite now

Thanks honda-tech!
