cam position sensor internal seal

superwhite · 04-22-2013, 02:55 AM

I have a 1987 supra with 44k miles. I replaced the oring at the gear. There is no evidence the internal seal is leaking but I wonder if I should replace it due to its age?

I'm pretty sure that unit uses a sealed bearing and I don't recall ever seeing a compatible one reported. Do you know of one?

There is a bearing internal oil seal but not listed as a Toyota part, but available as a repair kit from Link. This is a good link for rebuilding the CPS

If it's not leaking and the bearing feels good I'd be inclined to leave it be to be honest...
