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.

as the title say i have two females nagging me.
Both like to have a go at me whether it be beeping or shouting.
Both require regular servicing.
Both are expensive
Both like to treat themselves to new treads regulary
Both suffer effects of older age :nelson:
Both require a good oiling once in a while ;)
Both require constant attention :-)
Both make me look good :cool:
both can make me look like an idiot :cry:
but more importantly........... I love them both to bits and when things go smooth there is nothing that gives me more happiness
sorry but it had to get a bit soppy in the end :dance:
