My car has been pinging like a b!tch ever since i put the b16a2 block in it. I just did a compression test, and the results came out good. The block only has 20,000 miles on it, and everything else on the car has 40k on it.
My current setup:
B16a2 block
ITR everything else
Drag III turbo kit
It starts pinging at around 3-4k rpm when i give it 1/2 throttle gas. It sounds like pebbles hitting my windsheild. I am still running the stock injectors, and an fmu. Also, today after i did the compression test, and put everything back together, it started pinging at idle..( After i revved the engine a little bit ) I checked the sparkplugs for any signs of detonation, and nothing was there. I am open for suggestions! Thanks

 

You may have broken one of your injectors, FMU's are hard on injectors do you have a high pressure fuel pump?

 

injectors..time to upgrade that and get rid of the fmu and do afc hack instead.

I imed you back earlier but I was away from replying it. I'll take a look tomorrow and we'll figure out what the problem is..

Jeff-

 

Pinging at idle?????
Are you sure your hearing pinging and not the valves?
Whats your timing set at?

 

I've never in my life heard real detonation or preignition (pinging) at idle. Its like the guy who called at work the other day claiming to have over 260 Hz on the input line to a 3 phase machine that draws over 60 amps. Sure it COULD happen, but its not happening. Their is a better explanation...............

 

b16 block? thought it was gsr?

 

he cracked his pistons on his type-r. b16 is just for now while the b18c5 is being built.

Jeff-

 

Yeah, Dave, its b16..i wasn't able to find a gsr that quick. Found a b16 for cheap, and hopped on it. Anyway, you guys think its the injectors?? I'll upgrade them and see what happens. BTW, call me tomorrow or leave me an IM jeff. So we can figure this **** out. Thanks

 

Hmm, i don't think its detonation anymore...This morning, when i started my car, i revved it up to see if the noise was still there, and it was...could it be the valves?? or something wrong in the head? It sounds like pebbles hitting my windshield. After the car is warm, it doesn't do it when i revv..I don't know..this is weird, and its annoying..ehh, if anyone has any suggestions, hit me up

 

timing. Could be your cam timing is off, ie. timing belt is off a tooth. Do you have adjustable gears?

When the motor is warmed up the timing map changes and this could explain why the sound goes away.

 

bad gas?

 

these are the following problems

-valve dropped (ping ping ping ping ping)
-blown headgasket most likely caused by stretched head stud

solution....rebuild the head, rebuild the itr buttom end. he got a b16a long block from me and put it on for the time being..

Yup, but we wont' find out for sure what the problem was untill we rip apart the head. Anyway, thanks for the b16 long block for the time being Jeff. The turbo should *somewhat* make up for the slow *** b16 lol. *cries* Anyway, hit me up cliff, and i'll fill you in on the details.
Cheers to the siR. hahahaha

 

Check your valves.
Have you adjusted them recently? They do need to be adjusted every 15k miles.
It sounds like it's just valve tick to me (meaning valves need adjusted).
Every honda that i've owned has ticked louder when I first started it up, and as soon as it warmed up it got significantly quieter
