Eliminating the stock crank angle sensor

I've got a 6 port 13B running on an Electromotive TEC-GT, and was cleaning up the engine bay, removing everything that's unnecessary. The stock crank angle sensor isn't used anymore with the TEC-GT, so I want to remove it. I just can't find anyone else who has done that.

Does the stock crank angle sensor hold anything together inside the motor, or now that I'm running my timing off the 60-2 tooth external crank sensor and not using the stock one, is it a simple case of removing the stock sensor assembly?

I originally posted this in the Electromotive section, but there were no answers. I hoped the race car section might supply an answer.

Does nothing but spin itself, pull it and put a freeze plug in the hole with a little RTV.

Full Function has a nice billet cap they include with their trigger wheel kits if you want some bling. Otherwise, use the freeze plug as suggested.

Thanks! I just shot off an email to Full Throttle about their block-off plate. I'm a fan of solutions other people have engineered...it minimizes the chances of me screwing something up. If all else fails, I'll go the freeze plug route.

Oops, yes, Full Function. I called Full Function, and the price seemed right for the block-off plate (admittedly, not as cheap as a freeze plug), so I ordered it last week. It arrived today.



I'm hoping to install it tomorrow. Thanks for the tip about Full Function. I'd never heard of them, but they seem to make decent stuff.

Very clean, and an easy install, too.

Stock:


I removed the top of the crank angle sensor to see what was in there, but all you really do is remove the 10mm nut to remove the stock sensor:


Pull the stock sensor out:


Remove the stud:


And install the Full Function piece, using the supplied screw:


And for those wondering what it looks like down the hole:

I'd run a large breather out of that block-off plate.

Any reason in particular for doing this? The stock sensor didn't have a breather, and I already have a breather elsewhere on the motor.

Just realized that you have an n/a engine, so no, there is no reason to do it in your case.

With turbo engines though, that would be an ideal location. The blowby issue and the related oil pushing out of the engine that is common to road racing cars with turbo engines is well documented on this site. Some have come up with clever and not so clever methods of addressing the problem. None have a better solution than me though

Didn't mean to hijack your thread.
