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.

Resprayed my scuttle panel, or at least that is what I was told it was called at the front of the car (the thing that goes from right to left and the windscreen wipers attach through it) but it snapped! Has anyone got one spare that I could buy as it looks fookin shocking!
