All: Thank you for your responces. Any opinions on backwards connecting rods? IJ., Grumpy Old Man: Since the rods were in backwards, the rod-holes were spraying oil on the opposite side of the cylinder walls than was designed. Potential problem? Opinion? Motofool: The turbo was also...

8,000 miles and many years after an engine rebuild, my 87 Supra Turbo began to spew a large cloud of oil smoke out of the exhaust pipe and oil is found in pools throughout the intake system. The short-block (block, crank, pistons, rings, bearings) was done by a machine shop that was recommended...
