The knock sensor is bad on my Z-32 and I've read a couple of posts on
another site that suggests relocating the sensor to a drivers side head
bolt.

Anyone ever done this or heard of it done without any issues. The author
of the post does alot of engine work himself. Also read a thread about
jumping the sensor with a 1 meg-ohm resistor which reads like a bad idea =
no protection and kind of a mickey mouse approach.

Also read that the wiring sub harness sometimes will have wire breaks or
corrosion. Gonna get a new harness regardless, so that's one option.

I ordered the part for $120 from BuyNissanparts.com, cheapest price I've
seen so I've got a few days before the dreaded decision.
Also considered dropping the 5speed tranny and reaching the sensor that
way.

10 hours of work or a short cut, any advice would be appreciated. Thanks.

I just bolt them to the rear most intake manifold bolt that holds the
upper/lower intake together and tell people USE PREMIUM FUEL!!! It won't be
an issue if you use good gas.

Good luck! I have no idea how you'd get it from that direction.. It's UNDER
the lower intake manifold. You can't replace it with the engine out of the
car without removing both manifolds.

It's way more than 10 hours worth of work even if you've done it before! The
only reason to go there is if the engine also has leaking valve covers or
needs injectors, the EGR tubes cleaned out etc.

Turned out to be bad sub harness, 35 bucks well spent. I estimated 10
hours to reach the sensor, I've never changed a knock sensor, but was
guessing without looking at shop manual estimates.

Good to see others relocating to manifold.
Thanks.
