After many hours research and consulting OCS, I decided to try something somewhat new with my piston rings. I have decided to run Total Seal Gapless pistons rings. The setup includes a gapless top ring, with conventional second and oil control rings. To my knowledge I’m the only person in the UK to be running gapless rings on a VG30, but I know of at least one other in the states that have shown very positive results. The term gapless is a bit of a misnomer. It’s a 2 piece ring, with their individual ring gaps rotated 180 degrees from each other, effectively making the area around the ring gapless. The positives include virtually 0 blowby (so a 0-1% leakdown vs 5% on a conventional ring), increased vacuum and reduced oil fuel dilution. The other benefit is you can run a larger ring gap on the 2 pieces, allowing the a wider margin for thermal expansion without the downside of increased blow by The only real downside that I can see is the cost, at around 30% more than a CP Piston ring pack. Hopefully this will help with slightly improving my idle vacuum (due to my cam profile) and a generally more efficient engine.

Hi guys,
Am thinking of storing my car over winter due to the poor weather conditions we are likely to have.Also she is out of tax at the end of this month. What are your thoughts on this matter? And, what do you need to be careful about with the zed when storing it?
Cheers
