Gadgetman Posted September 9, 2016 Report Share Posted September 9, 2016 I have got hold of a new set of old stock Hepolite +30 pistons and rings for my Vitesse 6. The Pistons have a second oil control ring below the gudgeon pin, has anyone else come across this before? It's new to me! 1 Link to comment Share on other sites More sharing options...
dougbgt6 Posted September 9, 2016 Report Share Posted September 9, 2016 Yes, my GT6 replacement pistons had that last time I did a rebuild. Funny I remember it, but not whether the pistons were domed or not! Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 9, 2016 Report Share Posted September 9, 2016 of the day oil control rings below the pin was quite a common feature Pete Link to comment Share on other sites More sharing options...
efp Posted September 17, 2016 Report Share Posted September 17, 2016 Folk knowlege, and I believe the standard tome on setting our cars up for racing has it that the extra ring creates extra drag hence inhibiting performance. I'm no expert but I've learned over the years to have a healthy respect for the original engineers' wisdom and doubt they'd have gone to the trouble and expense of tooling up the extra ring without any good reason.
