Thanks. If you dont mind look at my UOA in the Gas UOA section. Im worried that over several o/c the oil that doesnt drain out of the engine will tend to let the ti continue to creep up. Virgin oil has 60ppm ti and over 2 o/c the ti is up to 80ppm. If this trend continues what will happen if ti gets up around 150-200ppm. Im thinking this could cause issues from residual oil in the engine. Not sure though just curious

I've heard of titanium rods, but I seriously doubt there are pistons made from it.
Some modern production cars use titanium connecting rods and valves. I have never heard of titanium pistons and cams in production engines. Drag racers experimented with Ti pistons back in the 70's, but they didn't work. WoO sprint cars were using Ti cranks in the nineties, but those were outlawed due to cost.
