AC compressor oil leak..

[BigRAWesty]

Well I've noticed quite a bit of oil running own around the AC compressor when under it threw the week.. It's also running down the chassis rail but I assume that is just spray..
It not enough to leave a puddle under the patrol but it was about to drip when I saw it..
I'm guessing it's my oil lube line to it, but how the f do I get to it..
I'm guessing I need to pull a bit out...

It's not power steer oil ?.

AC fluid they check with dye and fancy specs, Give it a good wipe .spray some degreaser and hopefully the culprit will reveal itself

The compressor oil and coolant runs in the same hose together doesn't it.

I had noticed bit of power steer oil leaking and making its way down around comp and chassie also.
That's why I suggested the alt explanation.

Sorry, td42 in a Q. The AC compressor is bottom passenger side under alternator, power steering is opposite top.

The A/C compressor oil is normally clear (unless a UV dye has been added to the A/C gas). It also circulates around with the A/C gas.

If the A/C compressor is leaking oil it is also leaking gas.

If your A/C is still getting cold and going by the amount of oil you have said you can see, I don't think it will be coming from the compressor.

It's possible coming from the vacuum pump on the back of the alternator.

I would give the area a good wash down and re-inspect.

Yea I've been looking a bit more and your spot on.. It looks like its coming from the vac pump..
So why??
I can see a couple of lines running back to the block. Does the vac pump has sump oil running threw it as lube?

Yes it has engine oil going to it, not really sure why.

Your leak could be coming from one of the hoses or the banjo fitting.

There is also an oil seal between the alternator and vacuum pump, normally if this seal is leaking the oil will go through your alternator.

Well there you go, its sorted, almost.
Fun and games.

Huummm, can you buy kits or recon units.
Sure Iv'e seen diesel alts on ebay?.
