I have one of the switch or sensor, i am not 100% sure which one it is. ( it is a 2.0 and mounted on the block by the oil cooler. it does not appear to be leaking, but I am not sire if it would leak when broken.
Anyway, as the PO was trying to take it out, It broke. 1- should I extract it and replace? ( I never extracted a bolt before) 2- Should I just leave it alone and seal it? if so what can I use to seal it? |

Paul, please post pics of how it broke. Did it break down below the surface where it threads into the case or above? If above, you may be able to use a dremel with a cutoff wheel to grind a slot into it and use a screw driver to extract it.
If it broke below, I would pull the engine and take stock. Do NOT drill it out and run a tap through it. It is a tapered thread, and if you tap it, you will have a hard time sealing a new one. |

It's actually a straight thread, though if it were tapered you could just tap it a little deeper if you did bugger up the thread. I'd try on of the square-shaped easy outs, they work a lot better than the twisty ones I think, after enlarging the hole with a drill- just don't go all the way through and chips will not get in.

I won't even begin to guess where you got this erroneous information, but it's now in the archives where it will confuse newbies until the end of time. It's 10mm fine tapered, which is functionally the same as 1/8" NPT. The correct switch will be tapered, as well, and will not use a gasket. The Cap'n |
