Hi just wondering why my engines leaking oil out of the sensor on the back of the engine behind the manifold. I resealed it with thread tape and permatex and its still leaking or blowing oil up through it. Can some body let me no how
it can do this?

Are you sure its not coming out of the cork valley cover gaskit under the back of the inlet manifold? This can be common.

.............ahh, the old to cork or not to cork debate. No cork for me thanks - just a big fat gaskit sealer bead.

Get a rag and some parts cleaner and really clean the area. The best way to fix it is remove the manifold (too hard basket), just try a bead of gaskit sealer smeared over the gap and let it dry overnight. The oil will make it very reluctant to seal though.

Those manifold corners are a pain. Especially the rear ones!

Years ago, actually had the sender itself leaking - as said, degrease the area thoroughly to work out exactly where the oil is coming from.

Mine is doing this too. I don't know about yours, but mine is a mechanical sender with the little plastic tube. It doesn't seal very well at all. Even with heaps of thread tape.

Any tips?

Thats odd, as they usually don't need a sealant to seal.

Yeah i put tread tape on mine and some permatex sealant and it still leaks so i think its the sender itself leaking or a leak from the back of the manifold
