the sounds of pinging?
 

what does it sound like? I used to think it sounded like a hammer hitting an anvil, but I have a noise coming from my motor and my dad says it's pinging. it's hard to describe, it's like a bunch of BBs hitting concrete.

Re:the sounds of pinging?
 

pull timing and increase fuel, see if it goes away.

Re:the sounds of pinging?
 

awe, that means I have to get my ass off the computer and go do something? doesn't anybody have a sound file or with pinging?

Re:the sounds of pinging?
 

sounds like my pecker wailin on your lips

Re:the sounds of pinging?
 

thats exactly what it sounds like. same noise your ass cheeks make when hotrex is tappin your ass.

Re:the sounds of pinging?
 

ever take the end of your hose and bend it? (like write where the water spits out of it). That sounds ALOT like what pinging did in my car before my motor blew up. I guess the other way to think of it is as the sound of tapping from under the hood.

Re:the sounds of pinging?
 

chacko helped, hotrex and RENR can eat a dick.

I definetely have pinging then, I hear it everyday yet my motor has not blown, I must be lucky.

I only started to hear this noise after I removed everything involving heating and cooling in my car and had to make a bypass hose for my lack of heater core. at first I thought it was the air bubbles in my bypass hose, but it could also be that I can hear the engine alot better without all that ---- in the way.

Re:the sounds of pinging?
 

Explain what exactly you removed?

I would ease up on the boost until you can get this taken care of. My car ran with pinging (I didn't know what it was either) for about 6,000 miles possibly more. Then I finally spun a bearing, and everything fell apart.

But any revolution with detonation is a chance to knock apart the motor. I almost gurantee that you're already suffering internal damage (the rods are probably starting to shake loose of the connecting bearings).

So get that ---- fixed so your motor lasts bro :)

Re:the sounds of pinging?
 

well I'm running max of 0psi right now, just running on bov power.

I removed everything. I took out the blower motor, the ac condenser thing, the heater core, the whole vent routing system and my whole center console with my hot/cold control and stereo. then I just hooked up the line that goes into the heater core to the line that comes from the heater core, and the little valve thing in the coolant line is closed.

also, it seems to only do it when I put the engine under moderate strain, like driving up hill at 30% or so throttle, but it isn't noticable at wot at all. also when I'm at low rpm and I press the gas from low to about 50% or more it does it. and it does it more when I have more weight in the car.

Re:the sounds of pinging?
 

Is your engine over heating then? I'm lost in to how you can be pinging that way hrm.... things must be running way to hot on your intake. Perhaps you should consider a water injection kit, or try running higher octane. Or maybe even... running a filter straight off the intake manifold instead of through the turbo piping :(. (I"m assuming you're boosted at some level?)

Let me know what you got in your setup, maybe I can help you out.

Why were you taking out your blower? Weight reduction?

Re:the sounds of pinging?
 

I just have the stock intake pipe from a 4th gen prelude and I cut a hole in it and put the bov in and put rubber sealant around that. I have some random cylindrical filter that I got at autozone. I took out the heating/cooling assembly because I have no ac and the damn temp know was stuck in the middle so it was no good for heating since it blew kinda cold air. and for weight reduction. the temp gauge says it's good, but I have overheated this engine before and caused big problems.

Re:the sounds of pinging?
 

Hrm... I would try connecting the filter (if its possible) straight to the intact manifold and pull all the piping out for now. See if maybe that helps with the pinging?

Keep an eye on the EGT if it goes slightly above the middle of the pathway you've got a hot honda :)

Re:the sounds of pinging?
 

sorry, I don't have an egt gauge yet, you keep over estimating me chacko, what you must remember is that I'm ghetto, I probably have a bird in the intake.

Re:the sounds of pinging?
 

lol, well I'm just worried about you spinning a bearing or something. This isn't your only car is it?

Re:the sounds of pinging?
 

it is. I'm working on a deal for a 4-door that "needs work". I'm hoping it's just the engine so I can just tear that one out and put my old d15b2 in there.

Re:the sounds of pinging?
 

what car do you currently have?

Re:the sounds of pinging?
 

check out the sig. 88 dx hatch. it has a b16a in it.

I called about that 4door and the engine is fine, the suspension is fucked. I'm going to go check it out today, hopefully hmt can help me out with passenger side front suspension parts.

I am now 87.352554623% sure that it is pinging, I didn't pay too much attention to it before, but when I drove it this morning it was cold and there was no pinging in the usual places. I hope my head isn't fucked, I need it for my LS/VTEC project.

Re:the sounds of pinging?
 

check out what is happening inside my engine everyday:

you ------- detonation.

Re:the sounds of pinging?
 

I'd garage it for now if you can and get someone else to drive you around then if you need the head :( Or be ready to buy a new one. Though generally its the BLOCK that takes the front of the damage in detonation (head usually suffers damage when you rev to high).

Re:the sounds of pinging?
 

Aight, peep dis:

Or, if you prefer MP3, just change the extension.

So, that's what detonation sounds like on me 1.6L Toyoda engine.

Re:the sounds of pinging?
 

that sounds like what I have, thanks for the sound clip.

I'm going to back the timing off today and see if it goes away, if not I'll just keep driving, if I do use the block it will be for a complete build.

Re:the sounds of pinging?
 

I wonder if maybe there is no coolant flowing through your engine? Your EGT may be showing inaccurate readings, as it doesn't read whats going on inside the engine. Hrm. I don't know thats very weird to hear of a factory engine detonating...

Are you using a chipped ECU?

Re:the sounds of pinging?
 

Giving the dizzy a full retard should definitely help, you will lose some gas mileage and horsepower but for general reliability its probably worth it? :)

Re:the sounds of pinging?
 

it's running off of a zdyne modified pm6, so it's not a factory ecu. there is coolant going through, because if there wasn't my water temp gauge wouldn't give me a reading. rather than risk gas mileage and horsepower I'm just going to open up that valve and see what happens.

Re:the sounds of pinging?
 

This is an overlooked option but,
how many miles are on your engine?
if it's in the 150k+ range chances are you've got some good sized carbon deposits in the combustion chambers.
If you've never flushed out your engine give that a shot(costs like 20 bucks). I'll bet that's what's happening.
the carbon starts to glow red hot after while you're boosting, and wham, detonation.

you can buy a flush kit, but I don't know if that deals with carbon deposits.

If you want squeaky clean clyinders/valve faces then buy this:
a few quarts of ATF
some new oil

drain your oil
take out your sparkplugs anf fill each combustion chamber to the top with ATF
let it sit over night
come back the next day and suck all of the ATF out iwth a syphon or those pretty lips of yours.
then refill the engine with oil(get something cheap, you're gonna drain it)
PULL the car out of the garage
crank it up, don't mind the smoke it'll go away after a little bit.
don't boost or drive the car at all just let it warm up at idle for a good 20 mins.
then take a QUICK trip round the block, don't mind the smoke. boost it a LITTLE if you want, this is just to get the carbon warmed up to will it will break up and leave out the exhaust.

bring it back home and drain oil, add new oil(the good stuff this time) and drive around until the smoking stops.

Re:the sounds of pinging?
 

everyone keeps forgetting: I'm not boosted.

This is supposed to be one of those low mileage jdm engines with 2 miles on them or something, but the previous american owner nawwsed this ---- up. my teacher for my automotive classes said to just run atf through the engine and let it smoke like ----, I'll try your method though since I'm due for an oil change.
