Car Forum / MINI / January 2006Rubber Rocker cover gasket?
Anyone know where you can get a rubber rocker cover gasket from, Im getting p***** off with having to reseal mine. Ben > Anyone know where you can get a rubber rocker cover gasket from, Im > getting p***** off with having to reseal mine. > > Ben Lol! No such thing I'm afraid! Some rocker gaskets are thicker than others, I use unipart ones if I can find them locally. Other than that make sure all surfaces are dry. If I'm having probs with a particular gasket then I'll use hermetite blue 'instant gasket' to stick the rocker gasket to the rocker cover only, then fit it! Another common problem is people overtightening them - they can leak quite badly. Haynes lists the torque as about 3 or 4 ft/lbs I believe! Also replace the oil cap! This should have a breather in it, again unipart are best here as cheap pattern ones wouldn't close properly on my MPi. chris > Anyone know where you can get a rubber rocker cover gasket from, Im getting > p***** off with having to reseal mine. > > Ben Hi, For years I have been sticking the gasket to the cover using evostick, and NEVER had any leaks. The evostick cleans off easily when the time comes to replace the gasket, after a service or rocker adjustment.

Recommends a good quaity alloy replacement. Haven't got round to testing the theory yet.

I wanted one of the alloy ones but the financial controller said I didnt need it! I guess she was wrong! (or at least misguided, when was the last time your financial controller was wrong guys?) Where does the main crankcase breather come from? Is it still on the valve chest cover? Any ideas on increasing performace, Ive got a little Pipercross thingy on my X1/9 can you get a similer doofer for the mini? Ben. >Where does the main crankcase breather come from?

You can get a K and N replacement element for the standard filter box. Don't go for anything more extreme as the ecu can't cope. Replace the exhaust with a freeflow system from the cat back. Replace the manifold with an lcb-type, but don't forget to get one with the take-off for the lambda sensor. These basic changes make a huge difference as the engine is strangled in standard spec. Don't be surprised if you get a bit of a flat spot at low revs with a low throttle opening, though. The ecu isn't very bright ;-)>. If you want to go for more (ie full 90bhp Cooper S Works spec), you'll need a new head and rockers.

I don't have problems with either original Mini's or MG tappet covers. I usually stick the cork gasket to the tappet cover with a gasket cement. Important - make sure that you get a fresh gasket that has not shrunk with age/storage. As I've posed before, I use two cork gaskets; one stuck with rtv sealant to the head, and one similarly to the cover. > Anyone know where you can get a rubber rocker cover gasket from, Im getting > p***** off with having to reseal mine. > > Ben |
