This doesn't exactly apply to fords only as i've seen it recently on a friends mazda 929. Before that i'd only seen it on Family Laser.
Engine was running fine with no issues then all of a sudden had a major pinging with light load. Originally sounded like piston slap or broken rings.
To get rid of the pinging the timing has to be brought back around 10 degree's and it seems to rev up fine. Put into gear and it stalls coz its so retarded the motor cant take the load and dies.
Bring timing back to normal... will idle happily in drive, but touch the throttle and it pings again.
Thoughts?
I'm wondering if the weights have gone in the dizzy or something?
Same tank of fuel.. still plenty left in the tank too, so its not gulping up bottom tank sludge either.
The friend has little money too.. so hoping to get this fixed at little cost. Guess he'll get my EA S 5spd next week unless we sort this out quick! (yes i'm generous enough to lend out the car)
Put a timing light on it, and as soon as you rev it up from idle.. like going from 800 revs to 1000 revs, it advanced about 30 degree's. Not a gradual climb as the revs lift, instant jump.
Ripped the rocker cover off (dizzy driven from front of camshaft), and there was cuts into a spacer from the dizzy cog teeth. The previous mechanic had installed it ass about face, so the teeth were hitting. Whacked all back together in the right way.. seems to turn better.
Once the battery recovers.. will try starting *crosses fingers*
Would the slight bump on the shaft be enough to throw the dizzy weights out that quick?
