It sure has been a battle to keep the blue smoke at bay. The original O ring seals were cheap and easy to install but wouldn't stay put. The head was milled and ground and prepped for positive seals. They fixed the issue temporarily but now take a look at how the 2 piece Teflon insert positive seals have blown out and been shredded. Those seals are obviously defective or not made for life in this motor. We've moved on to a 1 piece Viton seal that we're confident will cure our blue smoke plague.
