i got my oil pump cover back today thickness was .132" and i put it on the timing cover ,put it on my block with the timing chain all on and flipped the block over( its on a stand) and with out the gasket on i had around 1/16, so with the gasket i have more then enough , so i dont see how people are rubbing? i did nothing to my crank gear either...so by seeing mine all together and the clearances i have i think ill be just fine...anyone who has rubbed i think must of not put it on correctly maybe.....
