I had both the sleeve and crank worked on. I'll see if I can get pics loaded up.

ok, ive had my tr turbo for about a gallon of fuel and have been very dissapointed in its performance. I went to the track today and discovered the main front bearing has a leak, and a bad one, if i pressurize the engine fuel just pours out the bearing. Im not sure how long its been leaking as i didnt think to check it untill i realized today i had fuel under the engine. as far as performace i knew something was wrong today because it had a constant idle problem and was getting real hot when rich. so the leak explains it. before the leak problem tho the engine seemed to have very little bottom end power, but ok top end power, and no matter how much tuning was done to it it always seemed to run very rich and didnt really perform well runing at 220 degrees. When leaned out too 240ish it seemed to be fine on the top end but not on the bottom and was still rich. So i need to call os and send the engine in to be fixed, but i heard somebody saying they werent doing warranty for this engine because it was discontinued, is this true?

i think os does not cover warraty for the ostr turbo engine mainly because it's a high performance engine. what i do know is that they carry warranty for the bashing type of engines like the os cv series. by the way, it's the first time i have heard about a poorly performing os engine. all the os engines i have bought are in very good condition. in fact, i have an os hyper cv engine is use for bashing around and still in very good condition considering its 3 years old. no parts have been changed yet...

guys i've countered my heat problem with lowering the body as much as i could! too the point it scraps the ground when running with very low foam tyres. it was a unexpecting find as i did this as an experiment as i witnessed all the other pro drivers at my club having their bodies very extremely low. now the window hole covers most of the bottom part of my engine as well now. and now im running 230-240F at the speed i use to run at 270...
