I've got a 2.6 v6 24v f/lift 52 plate petrol with an oil leak somewhere up top of the engine.My local garage say pos. rocker gaskets,but not for sure. They have quoted 8 hours labour,and it might not cure it, but I think that's a bit scary. I'm not the best D.I.Yer,.Is it a job I could take on myself, or are there any members in Central Scotland who would help. It's an LPG conversion, by the way

There's a very good chance that it's your rocker/cam cover gaskets that've failed. But 8 hours?????????? :o :o Has your mechanic lost the use of both arms & uses his teeth to do the job?  :o :o :o
pm andyc for a full set of gaskets for around £80 - expensive but you only do the job once instead of twice if you use pattern parts. Your 2.6 makes the job a bit easier as there's less emissions gubbins in the way but when you do the gaskets, make sure you do the breathers at the same time. Have a look through the maintenance section for a how to do.  :y It'll take you half the time quoted by your garage.  ;)

Wow. Didn't expect to get a reply so quickly at this time in the morning, and it sounds like good news for once. I will deffo look into pricing the gaskets and see if I can get a mechanic friend to help.. Thanks for your help

Yep. Clean the breathers to stop the problem reoccurring, and 8 hours is ludicrous. Although, some of the LPG gubbins will be in the way, so it will take longer than on a non LPG car. :y

here's the guide for the breathers.  :y

Depends how the lpg is fitted, if it's got straws through the plenum that won't help.

It's 3 or 4 hours work normally if there's no oil in the plug wells to sort out. Stick some plugs in at the same time if needed.

Thanks to, AndyB, Albs, and chrisgixer for all your help
