1995 3.0 V6 Big end/guidon pin knock?
Posted: Mon Mar 14, 2011 3:15 pm
After more than a 100 000 km trouble free km's the following started to become more noticeable the last 5000 km's
- When you pull away and the auto box changes over, just as you lift your foot of the pedal to let it change there is a definate ggrrrrrrrr sound coming from the engine @ exacty 3000 rpm. If I rev it up to 3000 rpm while parked in the garage and keep it there it is definately there, coming from the left hand side of the engine.
This is not hydraulic lifters ticking as I've had that before and had it repaired.
It is only there when you let the engine "coast" at 3000 rpm. While accelerationg / de-accerlerating there is no noise. Does not use any oil and I check this every Saturday. Fuel consumption is still the same as 8 years ago when I bought it.
During the 260 000 km service I did bring it to the attention of the workshop owner and and he indentified it as a possible big end/guidon pin knock?
I currently do less than 10 000 k's a year and the question is must I keep on riding like this? My answer is obviously not as I am mechanically pedantic and would like to have it repaired asap. But in fixing this the engine will have to come out and then I'm probably in for another R8k on top of the recent R4.5k service. I can borrow the money and get it done, but if I can post pone it a bit it would help.
Is this such a big issue, or can it wait another 6 months or so? What are the possible complications if its fails? Engine seize and another rebuild?
Otherwise the engine runs very well and dead quiet.
Thanks gents!
