Just pulled the motor on my daughters VT and had trouble removing the clip on the D/S knock sensor (bloody fat finger syndrome lol) and managed to damage it, now the car seems to be running fine in the driveway (no road test yet) since being refitted. What I need to know is how inportant is this and is it ok to drive untill it is replaced ?

Secondly it is recomended that Holden part number M40124 be placed into the radiator after the coolant has been replaced, 3 pelets i beleive, is this also a must do or just something that Holden come up with to make a bit of extra cash ???

Thanks for looking and all answer appreciated Cheers Barry

Thanks Pete at least I can let the knock sensor slide now till after christmas, as for the water pump being original mmmmmmmmm I could not tell you if it was the factory motor or not lol. I may just chuck them in to be on the safe side, if they are not obsolete ! lol


Thanks again Cheers Barry

Thanks BluHJ, Now you have said that I remember the stuff now, I used it once before. This old VT my daughter has is an ex-cop car with nearly 280,000k on the clock and I just had to replace the aluminium plate on the rear of the motor due to corrosion (an obsolete part from canada now aparently) The rest of the welch plugs looked ok put I would say someone has put bars leak in it at some stage and I got stuck with the problem. So due to its age I think I will be adding the extra sealing compunds lol.

Cheers Barry

No probs Barry but I wouldn't buy an ex police car. I've driven them for the last 30 years and know how they're treated. Admittedly, they are usually well serviced BUT......they are usually driven hard, hot or cold. I've heard them on occasions leaving the station fully cold and hitting the governor or in the earlier ones, valve bounce before they changed. Maybe I would buy a country highway patrol car but definately not a metro one. I wouldn't even consider a general duties (station) car under any circumstances.
You've done well to get to 280 on the motor. Bars leaks tends to block up the radiator as well.
Even though the pellets are for the V6, I don't see a problem using it. You could try silverseal instead. My son in law had a big crack in the plastic tank of his commodore and used silverseal. Lasted 18 months before he had to replace it.

Good luck...Andrew
