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 all,
Has anyone driven to Switzerland (e.g. Geneva or Zurich) in late December?
What was it like? Is it possible or does the weather make it a no-no?
Also, has anyone driven in Switzerland in December?
We are thinking of going there but I am not sure whether to:
a) fly there and use trains;
b) fly there and hire a car;
c) drive there and use the car everywhere.
Using trains seems sensible except with 2 kids and lots of luggage, cars seem far more convenient.
Any advice much appreciated.
