Hey guys, I'm Ryan. I'm 16 but just bought my first project car- a 1987 turbo supra 5 speed. The car has 201k on it but I have some pretty big plans, including a complete rebuild. However, I have a few preliminary questions about the car. First of all, it needs an A/C recharge, but my R134a hose will not fit on the attachment. any suggestions? also, there is a light tapping in the top half of the motor somewhere about 3500 rpm. I think its the valves or head gasket but I'm not sure. Thanks!
