    Having trouble removing one of the rocker covers. Feels like it's welded on !
    Anyone have any tips for coaxing it off ? Thanks in advance :)

    Just a good jemmy bar or screw driver should do it. just yank down hard, should come ok.

    whoaa whooaa. the bail arm on the rocker cover or the actual rocker cover mating surface with the cylinder head? If its the second one and you go using screw drivers and so on all heavy handed you can damage the mating surface and hellp oil leaks.

    Try a moderate thump with a rubber mallet.

    Anyone had huge troubles getting the covers back on? They were tough to remove - I've replaced the gaskets and no matter how hard I push/pull/grunt & groan - cannot get the bail arms up past the first swelling on the cover. If I force any harder, the whole thing slides up a couple of mm and exposes the lip of where it should be attached.
    I figure it's going to be hammer time but if there's a gentler way please let me know :)

    Light smear of grease on the raised "bumps.
    I've also found that by threading a length of braided cord, looped under the retaining clip, your significant other can then pull steadily on the cord, which reduces the initial pressure on the rocker cover.
    The clip will then slip into place easily.
    Two outcomes achieved......
    1. the rocker covers are back on
    2. your significant other can now tell folks she worked on the engine.......bragging rights ! :cool:
    Cheers,
    Mark

    Backtracking a bit but I glue my gaskets to cover with silicone to prevent them dislodging.

    Use the silicone very sparingly and ensure NONE is on inside edge where it can get into the oil.

    Check that your clips are up the right way.
    Middle hump faces up.
    Allows clip to sit lower on heat exchanger thus giving more room to seat cover properly.
    They can be easily unclipped and reversed.

    Use rope to pull back as Mark has described.

    Don't force it as its important that the gaskets are seated correctly.

    A large flat screw driver can be used to ease clip over the cover bumps. Go with a bit of lube too.

    I use a 18/19mm double ended ring scanner which fit through the clip diagonally and then I lever it up from there.

    Thank you all - first thing I'll check tonight is that they are the right way around - that will be a logical start.
    The gaskets are in place with gasket glue - but the amount of pressure currently needed to even attempt getting the clips into place is forcing everything out of alignment. Hopefully the clips are just on the wrong way around and this will be resolved easily . . .

    The rope idea is great too - where I can I find a significant other though? Been looking for one a while . . . :)
    Seriously - thank you all. Lucky it's the weekend coming up and I can crawl under there with daylight for a change.

    Recommended that goo be only applied between cover and gasket. Not to head.

    Recall quite a few moons ago when I had Igor and having issue getting the rocker cover(s) back on + being flush/square :confused: ....... ended up the cover(s) was warped so had to get a replacement pair and problem solved ;)
