FWIW I had a bad one from ZZP (cam) that triggered a permanent code. That was quite fun to troubleshoot but I've been driving around with the 3 good ones since the weekend with no issues. He is sending me a new 3 wire one. It doesn't look or test bad but maybe the cam position sensors fitment is slightly sloppy.
The cheaper sensors probably just stole the eBay picture from ZZP.

What boggles my mind is how this can’t be remedied by re-designing adjusters and solenoids that don’t leak…

Rhetorical statement, cause I’ve never seen this type of issue on any other car I’ve owned. Oil leaks? Yes. But not through a damn wiring harness that goes straight to the ECU. Wonder if anyone who’s changes their sensors in the last year can comment on wether they’ve started leaking or not? I have the newest revision and changed them out last summer. So far no oil coming out of any of them.

Latest part number sensors and magnets seem to not leak by the group wisdom on this site.

Damn, we’ve been played. Same exact picture too.
Found another seller that’s got it for a nickel cheaper.

The fact that they stole ZZ’s photo makes my apprehensive to purchase from them 😂
i did message the seller and they confirmed it fits the m157 even though it’s not listed on the description which I found odd.

I ended up taking one for the team. Seller accepted my offer of $60 for the set. I wanna see if these are the same exact thing or if they’re knockoffs.

Edited my reply to be more clear. I was referring to the extension harnesses. I used OEM sensors. I did FCP Euro for the warranty but maybe I should have just saved $40 be gotten them from the dealer if they won't leak.

Just got these wiring harness pigtails in today - they are the exact same thing as what ZZ sells. Calling it right now, these are probably made by a Chinese 3rd party and not either of the two sellers on eBay.

Are these the magnet sensors, or the cps sensors? Do you have a link?

So one thought I have had. the reason the capillary oil wicking action occurs is partly because the wires are stranded... which you obviously want in a car for flexibility and technically a smaller wire can handle a larger amp load with less resistance. Couldn't the extension harnesses be made out of solid wire for the short run, which would lessen the wicking action?

a drop of solder at the beginning and end of the wire would accomplish the same thing you're thinking of
