He should also measure the piston pins and pin bores. Plastigage clearance is usually around .0015" - .0020". If the journals are still at spec then stock bearings will be fine. Otherwise, with such a small amount of clearance it doesn't take much before you need to look for oversized bearings. Was the engine ever hurt or make any noise? If not and it is just a maintenance rebuild you should have no problems. I don't have torque specs at the moment but that tells me that your friend should get a repair manual for his car. If you are going to do your own work it is worth it's weight in gold.ALWAYS change both timing gears when replacing the timing chain. It's kinda like a new flat tappet camshaft and new lifters. You don't ever re-use the old lifters. The gears and chain are typically sold as a set anyways. Best to get a double roller.Even if he is not going to get any machine work done he should hone the cylinders. They are likely to be glazed and this will not let the new pistons rings break in correctly. Steve</blockquote>
