Ive retarded the timing to 16btdc, Ive added fuel additive and 93 octane and this damn engine still pings like a champ. any ideas would help greatly

 

any details on spcifics of what engine this is??

mods?

when does it ping?

 

The motor is a First Gen B16 and It only pings under load. It is completely Stock. Im running some Boush plugs...

 

I would change those plugs and use some NGK's. Have you checked and adjusted your valves? If not, I would check that out as well. Maybe you have a lot of carbon built up on either the valves and/or the pistons.

 

try adjust your valves

 

Have your fuel injectors serviced.

Get an aftermarket oil catch can.

 

change your fuel filter also and get rid of those plugs and get some ngk's

Using the stock PR3, I didnt go with the NGK's cause the only plugs they had in stock were iridium plugs and they wanted 10-15bux a piece.

 

like they said before, oil catch cans rock, the cleaner the better, and if its not just carbon build up its problay worn guides

 

well if you are pinging id retard it even more, at least temporarily til you figure out what's up. also just to name another one of many possibilities, i remember someone saying that if you are using a smaller fuel rail (possibly a dseries?) then it can cause problems with fuel delivery.

 

I have the ign timing as far as it will go on the dizzy. Im also using a timing light. I dont think an oil catch can will fix the problem. I know its not the valves making the noise. How could the valve seals create detonation? Should I try some SeaFoam to rid of excess carbon?

 

as far as trying seafoam id give it a shot, its already pinging,what have u got to lose? i also dont think an oil catch can would fix the problem, but theyre good to have nevertheless...

 

u should try and adjust your valves, its free to do, only requires time, well maybe a new valve cover gasket.

 

Are we sure it's pinging we're hearing? A loose timing belt can cause a pinging like noise that can really mess with your head...

I hate the night shift!
