we had the car out on Saturday out cruzing. had it sitting at 7000rmp in third gear bout to change into 4th.
and the motor made a ping sound then just shut down. got the car back homeand done afew tests on it.eg got spark, fuel. done a comp test sitting on 100 pound over all 6. lifters and push rods are fine. the dissy gear is fine. the only thing I can put it down to is. with the motor at tdc on number 1 the rotor button is pointing past no1 on the cap. could that mean we have striped the timming gear on the cam sharft??? anyhelp would be good

I does sound like the timing gear. If you crrank the engine over does the rotor button turn? |

It must be turning, otherwise he would have no spark or fuel. It could just have jumped a tooth on either the cam gear or the distributor drive gear. BTW, 7,000 rpm is serious revving for a street Holden 6. Dr Terry |
If at first you don't succeed, just call it Version 1.0 |

.... and in 3rd gear most likely a considerable speed. Edited by user Thursday, 31 January 2013 8:40:15 PM(UTC)

If you reckon you've got comp, spark & fuel...start from scratch. TDC on No.1 comp stroke. Move distributor to get rotor on No.1. Then try for start up.

At a rough guess.....150k's??? Perhaps have your tacho calibrated too. Edited by user Thursday, 31 January 2013 11:16:08 PM(UTC)
