After purchasing the Arnworx tools, a quarter-inch torque wrench, all four belts, tensioners and rollers I think I’m ready to complete the front end engine belt job on my 87 NA. I feel like I should replace some of the seals as well but am not quite sure which ones to purchase. There are kits but that might be overkill. Could anyone recommend which seals to replace while the front of the engine is apart?
