I have a problem with my jdm hi-comp b20 i want to see if someone can give me a lil help. I got it from hmotorsonline since I've had it I only put 120 miles ..Its making a ticking noise I cant seem to figure out what's causing it. To me its sounds like it coming from the manifold/ fuel rail area.. I took a video to see what you guys think. Link below

setup

jdm high comp b20
walbro 255 fuel pump
skunk2 manifold with hondata gasket
Stock Ls fuel rail and fpr
type-r throttle body with p2r gasket
3 inch short ram intake
Plm (rmf) headers
2 1/4 piping with no cat and a ws2
chipped LS ecu with b20 basemap

 

the videos are private so i cant see them.

did you check the valve lash? the b20's specs are tighter than the vtec's.

also, ive seen more than a few of them have a little tick or clack to them from that area. most often it goes away once warmed up might just be the rocker arms warming up and coming into spec

 

ama check dat this weekend haven't had any time this week ..the videos should be public now

 

My thoughts are it's one of two things... valve lash or loud injectors. I've heard some nasty injectors over the years and it's amazing how much noise they can make.

If you don't have any fancy way of listening to the motor (diagnosis microphones, stethescope) you can use a long pry bar or screwdriver. Touch the pry bar to the part of the motor you suspect is making noise and put your ear directly on the end of the handle. The sound will travel right up the handle and you'll hear it perfectly.

 

Long screwdrivers work too. I swore an old car of mine had noisy valves till I realized the injectors tick louder than the valvetrain!

 

Last night I changed the injectors 3 times all different sets that are used and leaned over the valve cover /manifold area the noise was still there after trying each set. I went and got a stethoscope today put it on the injectors I can hear the injectors tick . I also put he the stethoscope all over the valve cover and the tick doesn't sound like its coming from there. since the tick is coming more from manifold/fuel rail area and is fairly loud which doesn't sound normal to me comparing it to my boys jdm low comp b20 and his stock crv high comp b20z. . im going to bring my car to a shop that works with Hondas , they build and tune there to see what the mechanics say
