1929 Super Six pistons
Hi, I have recently bought a nice tidy, low mileage 1929 Super Six. However, the engine is suffering from quite a bit of piston blow-by, which smokes out of the side cover breathers. I am keen to rebore the block but see that replacement pistons are quite expensive (over $1000). Has anyone played with installing "other" pistons into a 1929 Essex? I see that Triumph 650 motorcycle pistons are a pretty close match - 71mm OD, the right compression height, 18mm gudgeon (which could be bored out to suit the standard Essex) and only around 2.5mm shorter overall piston length. Good quality pistons are available for around half the cost of aftermarket Essex pistons.
