Fluid Leaking Onto Crossmember... Where Is It Coming From?!

[CRoNic...]

Hey,

I've got some sort of fluid leaking onto the left hand side of the crossmember. So, if you're standing in front of the car, in front of the headlights, it's dripping from somewhere underneath the plenum or even further back towards the firewall.

I don't have any equipment to jack the car high enough to get under it, but if I lay on the ground and take a squiz, I can see it. It looks and smells like oil, and it's fresh.. plus I've lost a bit of oil, so it must be it. It must be leaking very slowly, as I've never noticed any stains on my driveway or anywhere I park.

I've checked everything at the top of the engine, and got a torch in to where the oil filter is screwed on, and that all looks fine... So what's around that area, underneath the plenum, that could be leaking? Oil pump? Any certain seals? Something with the sump? Some sort of oil line to the turbo's?

Cheers

Things to check on that side of the engine- start with the dipstick, if you have bad blow by this can pop out but if it does you'll usually see it splattered over the chassis down next to the battery and hicas pumps, and you probably would have noticed this checking with a torch where you did. Check all fittings on the oil filter block inc pressure sender and temp sensor? All turbo lines are on the other side. It's tight in the there and a real pain- you're going to need to get under and have a look. You won't see much oil on the driveway as there is a under-engine sealing tray (forgotten the proper name for it) that catches it all. You'll need to take this off for a proper look to, so befriend your nearest decent mechanic or invest in some ramps and/or a decent jack and stands.

No worries. The dip stick hasn't popped out, and I don't have a blowby issue, but I'll book it into my mechanic next week!

Yeah I noticed that tray! I guess it would get pooled up in that.

front diff breather hose has more than likely come off

Could be front diff related, diff oil a bit different to engine oil, still losing engine oil though? Do check to make sure it's engine oil or diff oil (which will probably more like a red colour)
