Leak from cambelt plastic cover

Cant really see where its coming down from in that picture TBH but check its not just run down from the oil filler when you have topped it up, failing that it will most likely be the cam cover seal on the cambelt end.
Aux belt looks dry, whip the top engine mount off and see if the cambelt is or not, if there is any sign of fluid on the cambelt, then you need to treat this as a major problem.

Thanks for replying. It's coming from the plastic cover at the top of the pic. Is it easy to take the engine mount off?
How major do you think it could be?

Yes its easy to take off, just 3 16mm bolts holding it on, but you need to support the engine while you do it, so stick a jack under the sump (with a lump of wood or a cloth etc on it to avoiding risking cracking the sump)

You can then see in to the belt.

Sure it's from there. OK let's say it is, what do you reckon the problem is?

If its from there, then most likely options I would say is either it is one of the seals on the cams or the join between the cam cover and the head.
Both of which are cambelt off jobs, hence a lot of work :(

That oil will have ran down from the top of the engine, most probably as above mentioned,rocker cover or cam seal. i'd take the top cam cover off and have a look,unless you can see a leak from the rocker cover through the inlet manifold......

engine in, essentially a cambelt change.

Yeah once you are as far as having the belt off its a relatively small amount of extra work to reseal the cam cover.
Hateful job though, cause you dont know if you have got it right or not till its all back together again, although thankfully it does normally go to plan if you know what you are doing.

Bear in mind that to "take it off" you have to do the cambelt, as unlike most engines the cam cover is also the the cam retaining caps all built into it as well, so when you take it off the cams will get pulled out by the tensioner yanking down on the pulleys (plus you wont get it off past the dephasor anyway IIRC)

Tell me about it! Its 'my' job at BTM, hate Fred for that.

If I take the plenum off will I see the rocker cover?

No, you will need to take off that mount I said, and shine a light in and you might see enough to tell where its coming from, if not you will need to start taking more apart sadly, the plenum doesnt need to go anywhere though, that can stay on (while you look, not while you take the camcover off to fix if its that of course!)

Sorry i meant cambelt cover not camshaft cover.......I'd take the cambelt top cover off,sometimes the rocker cover leaks inside the cambelt cover and down the engine.........
