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.

It would appear that the aforementioned
"Speccy Twats" on the M6 between Knutsford
services and Holmes Chapel have been removed?
Could this be the effectiveness of Tooley & co?
Or, are they indeed the new ones i have seen
being erected between J9 and Burtonwood
Services on the M62 Warrington?
Where the roadworks are taking place for new
junction 9a.
They are not yet in service, i will post when
then are.
Can you imagine the amount of pressure the
guys who install them are under to get them
up and running?
LASH! "Come on you fu*king lazy bas*tards,
LASH! we`re losing fortune here,
LASH! Get them Speccy Twats on line!"
It`s only taken 14 years of local campaigning
and being a prisoner in my own home to get the new junction 9a, it`s taken 2 weeks to
install the Speccy twats!!!!
