Can anyone tell me where the oil suction port is for the engine? I need to siphon off a slight overfill and don't want to remove the sump plug.

I have a Pela siphon, but need to know where to stick it!

I think It's just next to the oil filler cap. Small black cap with a circular arrow on it. (Assuming that's what it is for in any case.) the cap twists off and pulls up.

There is no sump plug, but there is a push on hose at the bottom of the sump, which can be pulled off slowly to release a little oil. There is nothing that can't be fixed with a hammer😜😜

There is what looks like a dipstick tube front left with a black twist top

That said, I’m not sure a Pela siphon will fit down it

The tube is very thin!

Looks like it's designed to have a connector pushed on the top and the tube itself acts as the siphon pipe. There is nothing that can't be fixed with a hammer😜😜

Never seen the JLR system I’m afraid...

Thanks all, found it. That is indeed a very thin tube!

Does your Siphon tube fit?

Nope! However problem solved here; I turned the car around because it was on a slight slope and problem solved!

The siphon tube is a similar diameter to the Pela tube, so I think that I could have adapted the end of the Pela with a tube sleeve slid over the end and sealed, and then placed over the engine siphon tube.
