I currently have a broke 2006 Honda Pilot exl with a j35a9. The block is no good (bad rings in cylinder 3). So i have a rebuilt block from a 99-01 odyssey j35a1. No i know i can put the heads from the pilot on this block. I'd have to get the alternator, power steering pump, and ac compressor for an odyssey for this to work. So here is the issue, the crank postion sensor is different. Now i know it can be pinned to the older sensor but will the computer recognize the older sensor or will it just simply not work? Any imput would be awesome. Thanks this is my first post on here

If it's just rings on 1 cylinder, does it make more sense to take that head off, take that cylinder out and replace the rings and then only replace 1 head gasket?

 

Also, why won't the accessories for the pilot work?  What's different?

It had piston slap in the cylinder. Block is garbage. The serpentine belt set up os different. All i really need to know is if i pin out the odyssey crank sensor into my harness will my computer recognize it

Are the crank wheels different? If they are the same i'd say there is a reasonable shot that the different sensor would still work. 

but I can confirm nothing!

The 2 blocks have a different style of crank sensor so thats why I'm worried it won't work. Don't want to do all the work to put the motor in if it won't work

Yes the crank pulley is different. The power steering went off the crank on the older motor and it's a serpentine on the newer one

But the crank sensor should be picking up on "teeth". Same number of teeth? Or is that what you mean by the crank pulley is different?

Here's just a random image but it hopefully shows what Im talking about.

The harmonic damper has nothing to do with the crank sensor.  The trigger wheel is behind the timing covers.  (IIRC it is part of the timing belt pulley/sprocket/cog)

I would recommend selling your block and buying a newer one, there are tons of them out there.

The odyssey crank sensor only has 1 pickup and the pilot one has 2

The only difference with the crank pulley is the odyssey one has the power steering belt off of it and the pilot one has a serpentine belt. But the timing belt is the same for all j35s i think.

In reply to RobDavis1284 :

Why do you need to change accessories?  All that stuff is just accessories.  Are the mounting points on the block different?

For all the effort for using an older block, I'd think it way easier to use the correct engine...

Yes the mount points are different. The reason I'm trying to use the block is because i got it fod next to nothing

Free parts are often the most expensive, once you add up all the bolts and gaskets and misc stuff you will need.

Also, assuming that the heads are compatible.  And that the trans bolt patterns are the same, didn't Honda change up the bellhousing at some ppint?

Yes i already have it 90% assembled. I know everything else will work just need to know if that crank sensor will work with my pilot ecu
