Engine Pinging?

[GripEnemy1992]

K so i was driving fast one day downhill and hit a really nasty bump around 50 mph and i have stiff coilovers so it hit hard, my motor has started pinging since, i have reduced the timing because it was way advance i have it at +15 degrees right now, i just put on a front mount instead of the side mount and it pings less but still does, any more ideas to reduce pinging?

Thanks

There really is no logical reason why hitting a bump would cause "pinging".

Are you getting good fuel pressure (maybe you pinched a line somehow when you hit the pump?)

How long was the car running okay before the problem started

it can if hard enough

lol, whats up with the phone #

a vibrating bolt or fastener isnt pinging.....pinging is spark knock caused by too advanced timing, excessive boost, incorrect octane fuel, etc

That's what I was thinking the OP meant too....

oh my mistake i thought we were just reffering to the description of a sound not spark knock

Does it sound like marbles hitting. You might be experiencing detonation, maybe retard you timing to see if it goes away.

If its more of a knock could be something like rod knock or piston slap.

I'd get your problem fixed asap as det. could result in blown ring lands.
