Hi all need some valued help and advice if possible just had my rocker gaskets done after more than selveral attemps the right sealer,original recormended gaskets oil breathers clear and still a ongoing mega head ache but after a drive out the other day and checked under the car nearly died oil down both sides of the box again and dropping off the bottom bolts.
Been assured by my man at my garage whom I tend not to dissagree with but just checking you understand with you guys ,Hes said  that the rocker gaskets are deffinatly ok now.
But after my test over the weekend out into the country thought id hit the sport button and give her a bit of a zip you know all seem ok until i got back and i checked underneath. 
But my man is pretty sure its now or has also been  the rear crankshaft oil seal leakin (still checking)my question is what sort of job is that to do time wise  difficulty and the cost.
You see We have been deliberating with that much oil that has come out of the rocker covers overtime and one time inperticular that could get in the  box then thrown back out via the flywheel or is!! it the oil seal.
Help please guys thanks

are the half moon covers at the rear of the rockers covers in securely just a thought

Rear crank seal leaks INSIDE the gear box bell housing. Then drips off the two bolts on the bottom as you describe. There is a gromit to the bell housing that can be removed. If its dry in there the rear crank seal is fine.

Print the breather cleaning guide off and show him...?

Rear cranck seal involves dropping the gearbox. I paid a local garage £250 to repalce mine ..... too heavy to do myself.

As said it cant possibly be rear crank seal,if its leaking down the sides from the top of the bellhousing. It can only be from the camcovers. Either the half moons aren't seated properly at the rear of the camshaft covers,or he has overtightened the *covers so they are warping and leaking.

* strictly 8nm only.

Try and get as much of the gearbox/rear of engine steam cleaned so that you can see where the oil is coming from. It's hard to tell where leaks are if the area is full of old oil & geaneral crap.

Hi  guys thanks for your replys to this, in responce to them .This last attemp he did mention that he did come across oil in the box which he cleared as much out as he could I guess through this gromet you speak of and assured me half moons etc were ok and  all areas dry and clear of oil.
But as Ive mentioned after i got back from my run out with it found fresh oil from high up running down both sides of the box and dripping off the bottom bolts.

Well, that's certainly not from the crank oil seal. Either the cam cover gaskets are still leaking or perhaps the oil lines to the cooler are leaking inside the valley.

If you've oil high up on each side of the block, it's not the rear crank seal. Cam cover seals are still goingto be the culprit ...... How about the breathers? If they're stil blocked, you're piddling in the wind with the cover seal till you sort the breathers.

Imo you would be better off getting an OOFer to have a look at it. Guffer does mechanic work,and I believe hes not that far away from you ?

Main pint being, it can't possibly be oil from the crank seal, if the oil is outside and above the bell housing. As Kev says, the only possibles are cam covers and oil lines to banjo bolts in the v of the engine. To check this the plenum, inlet manifold and plastic wedge need to be removed. But a leak there is rare, especially to the extent you describe.

 For oil to leak from both sides, and from the top of the engine, I would suspect cam cover seals poorly fitted .... or cam seals(not likely to the extent you describe)

[CG2]

In other words... I think he's cocked it up!

What seals and sealant where used...?

Also...

Keep a very close eye on the oil level. At that rate of loss damage could easily result. Keep some oil in the boot.
