i noticed yestrerday that my rear window on thmy 3ltr v6 mv6 estate had some shit on it but didnt realize it was oil. Today driving dlown the motorway a check my rearview mirror and the motorway is full of blue smoke from my car....
im right next to the services so pull in and turn the car straight off , get out and look at the the top of the engine .... no leak. then i kneel down and there is oil pissing out from underneath. The aa turn up and he jacks it up wipes it and when i run it (its cold by know) it hardly leaks at all but he thinks its rear main oul seal.
the largest quontity of oil is all over the gearbox but it aint gerbox oil.
im sorry to say it but ihate taking the aa for gosple as they have led me up the garden path before . anyone got any other ideas?

I had this on my 2.0ltr when one of the camcover gaskets let go at speed going up a steep hill. Same as you, no rear view vision (smoke). Pulled over, engine top clean, oil over the road, took nearly a litre to top up. Check the plugwells first, you might be lucky

cheers mate will do

Which engine?
The crank seal is unlikely to leak so much, a tiny amount causes clutch judder and slip.
Much more likely to be blocked breathers allowing pressure to build in the crankcase which then escapes from the weakest point....usually the cam cover gaskets.
Get some gunk or jizer in a garden sprayer to soak the old oil then wash off with hose. You should then be able to see where it is coming from.
If there is oil in the spark plug wells as mentioned before then defo camcover gaskets but you still need to clean the breathers.

its a 3ltr v6 auto 2000
this is sounding more promising tbh i aint even looked at the car since cos im so anoyed . this weekend im going to try and get to the bottem of it though.
any other ideas????

As said by others ... my money is on the cam covers .... how often has the oil been changed ?? when were the breathers last cleaned PROPERLY ?
Its a one day job the first time to do both cam covers and a full clean of the breathers and it will solve a lot of problems.
Check the plug wells, any sign of oil and you've identified the problem ... :)
The guides section has several usefull guides on covers, breathers, and plenum removal ... I printed them all off and had em propped up under the bonnet. They are now laminated and kept for future reference. (I just wish I'd laminated them the first time .. would have been so much easier !!!)

spot on .....
right thats it this weekend its a rocker cover chance i feel
-
i am so anoyed .....
i really do aprecate the help ive had here and really need some more......
i went out yesterday and bought all the bits needed for the riocker gasket change plus a heater control valve to do that while i hade the engine in bits too .
spent all day doing it today including cleaning all the breathers too , and it still has the same problem.
so i jacked it up myself ( cos only the aa man went under there ) and there is oil everywhere but i think it may be sump gasket now, what do you guys think .
im pritty shore its not rear main cos looking thought the inspection hole the back of the fly wheel is dry and i prosume that would be covered in oil .
