Good info above on the input shaft seal. Thanks, 745 TurboGreasel!
Be aware that replacing the input shaft seal may be a short-lived solution, if the shaft bushing has worn oblong (usually because of previous excessive IP belt tension). The excessive shaft runout will cause the new seal to fail.
So far happycamper, you are at hi-press head seal, and input shaft seal. Better to remove the IP for these projects. Is there a way you can measure input shaft runout to get a better idea of the bushing condition?
Yes, timing belt change requires timing tools, camshaft positioning tool, crankshaft bolt torque multiplier, and crank pulley lock holder. Sorry my terminology is off, don't have the patience to research correct tool names at the moment.
