Just a quicky!

I'm replacing my Lambda sensor this weekend, - the sensor has been bought, along with a new exhaust header gasket, and if needed, a new exhaust gasket.

Now, I've managed to purchase a new wobble socket set with a 150mm bar, but the exhaust header nuts are in a really tricky place. Any idea what size the nuts are 12mm? 13mm???

Cheers

Graham

If those nuts look rusty, the night before I'd apply some rust penetrating fluid on them. It might just help in getting them undone.
