Does anyone know the thread size for the Lamda Sensor, and also the PCV valve on the manifold ?

Need to tap the boss on the downpipe as it's been welded up.
And block off the PCV valve hole on the manifold.

Lambda boss will be M18 x 1.5

PCV AFAIK is M12 x 1.25 but not 100% sure on that.

See you at the next Aberdeen meet and we'll discuss it or Mail me and I'll see what I can do to help!

I'm planing to pick up a bolt to fit it at work, on Monday. I'll just carry the manifold in with me to check.

Also need to borrow the taps for the exhaust (And maybe borrow someone to do it for me )
