I have a D15B8 engine in my 94 civic coupe. it has 140k on it. the head is noisey at low rpm's like it sounds like maybe a loose valve or rocker but once you push the gas pedal down past 1/4 of the way the sound lightens. it runs strong but also burns about a half a qt of oil every 1000 miles or so. should i be concerned at this point and what could the sound in the head be? not sure about the B8 heads on being noisey. I know the B8's head is designed different than a B7 head. any info would be appericiated

Probably just needs the valves adjusted. I would start there. Even then i wouldn't be overly concerned, you can usually hear some valve train noise on d series motors anyway.

The only REAL difference is the lack of valves (8 vs 16). Generally speaking, the only thing that moves inside the head are the rocker arms and valves in relation to the cam. Check your clearances.

thats what I thought to. im gonig to check my clearences and let you guys know how it turns out. thanks

I just adjusted the valves but the sound is still going on at higher rpm's like after 3,000. any ideas what I should do next?

Is the noise a tick or a knock? Are you sure it is coming from the head

r.etheridge

its more of a tick, a very rapid tick. im 90% sure its comming from the head. I can put my hand on the head and turn the throttle and feel it. I think its something to do with the valves just not sure what at this point

Did you adjust the valves when they were completely cold?

r.etheridge

yes completely cold. it set over night in the garage
