I was looking down into my engine bay the other day, checking my fluids when I noticed something that didn't quite look right. It seemed that my drive belt wasn't connected to every pully in the bay. In fact there are three pullies that when the engines on are just not doing anything it looks like. At the moment theres a JDM engine sitting in the bay of my 87...could that be the reason? I know the shop that I had the work done had to replace a lot of the JDM external parts of the engine with their USDM counterparts for smog reasons. What do you guys think?
