Reply to "Engine rebuild"

I just did a search of composite / poly gears. One guy whose engine just stopped, showed a picture where the gear sheared at the roll pin. His mechanic had drilled an additional hole and most likely weakened it. http://www.ffcars.com/forums/1...or-gear-failure.html
A couple of other threads, with completely stripped gears, one running 20w50 oil with a hv oil pump. No failures on Tri-Tec that I saw, interested to hear any real world experiences with them.
With the bronze gear I presume you might see the sparkly shivers in the oil, not sure about the poly / composite. I checked my timing the other day to see if anything had changed, maybe one or 2 degrees less than where I last set it. I will check it again ~500 miles, I engraved my timing marks on the flywheel so I can check it from the back of the engine.
