Guest steelcabby Posted July 11, 2009 Share Posted July 11, 2009 (edited) Pinking is the nicely descriptive word for knocking or detonation. (i.e. you can hear 'pink' 'pink' when detonation is occuring in your engine). Detonation occurs when your fuel/air mixture prematurely detonates due to high heat/pressure or a high octane fuel with a dumb car (no knock sensor). Normally only an issue with highly modified cars or badly set up part modified cars. This can cause damage to points, valves and engine block. Having the combustion occur when the cylinder is not in the correct position to deal with the small explosion (i.e. on its way back up) can knacker your cylinders, and all the gubbins that's attached to it. Like most of your engine.. so basically you need to get your car set-up. probably badly timed or bad fueling. it can most likely be abit of both TBH. get it done right. if your not clued up on setting your car up. your kill your engine. if you lived close i could set it for you.

Guest Ady Posted July 11, 2009 Share Posted July 11, 2009 hi everyone, can anyone tell me what engine "pinking" actuallly is? how its caused and how you sort it? thanks! not the colour, hehe. its mainly caused by unleaded fuel in older engines pinto suffered bad from it, some times timing can reduce problem, it happens under load from engine, its a discription of the noise it makes ie : pinking, some engines u can put the lead replacement in fuel which will help.

Guest steelcabby Posted July 11, 2009 Share Posted July 11, 2009 cam side timing might be perfect, but dizzy timing might be wrong. i would turn your boost down to standard and put some decent engine cleaner in. what spec is it running BTW??

Guest steelcabby Posted July 11, 2009 Share Posted July 11, 2009 also what boost and chip? Quote Link to comment Share on other sites More sharing options...

Guest steelcabby Posted July 11, 2009 Share Posted July 11, 2009 so it was running fine before hand?? oh and sorry, didn't know it was a non-turb. not many of them left these days...lol. i would say you have a fueling issue somewhere then. or maybe even a ecu problem Quote Link to comment Share on other sites More sharing options...
gingergman Posted July 11, 2009 Author Share Posted July 11, 2009 yeah itwas fine before the rebuild and during running in. i didnt wanna turbo it cos of more probs but im having enuf with the 3i lump lol. shall i rolling road it? i dont wana damage the engine if somthings wrong! thank you for you advise mate Quote Link to comment Share on other sites More sharing options...
Guest steelcabby Posted July 11, 2009 Share Posted July 11, 2009 it would be good to see what the problem is.........you could get the compression tested and the fuel pressure tested. could have a dodgy fuel pressure regulator or a problem with the metering unit its self blocked up injectors could be another possibility. sorry but there are tons of options for you to try.

gingergman Posted July 11, 2009 Author Share Posted July 11, 2009 the compression has been tested and is max, if a rolling road speciaist can find the fault il give that a bash Quote Link to comment Share on other sites More sharing options...
