Hi all,
After realising that the source of my rocker cover leak was due to the case being over-pressurized ( PCV on one rocker, non-breathable filler cap on the other) I replaced the filler cap with a little dome breather and no more leak.
Over time and because I have those stock MOPAR ali' rocker covers that have no baffles, the sponge in the breather has taken up oil and is now, albeit slowly, leaking out during a drive and covering all my pretty coloured plug leads in oil droplets.....
Can I find a "baffled breather" with a lock-in bayonet fit ?
Is there a "home-fix" that anyone has done without the need to remove the rocket/replace gasket ?
thanks in advance

if the rocker covers are the alloy type the gaskets are often more substantial than the usual thin cork ones so can be reused if put back the same way round and assuming they either stay on the head or come off cleanly.

as for the breather not sure to be honest

used an inverted (inside out) Lego tyre with a roll of pot scourer (like a "roach") and a cable tie and attached the rubber (lego piece) to the inside of my breather ..... ran the car for an hour and nothing melted or came adrift ......
Now that my son is 16 I've got hundreds of lego tyres I can use ...
