Hmm, MOST 940's have the distributor back there.
If you have the distributor up front, near the alternator (mounted in the normal location for a 240 engine) then you have a cap, called a Cam Plug in the back end of the head.
I'm going to go on the assumption that it's this. You can lose a LOT of oil from it when it pops out. Here's what you'll want to replace:
1378870 Valve Cover Gasket (B230F including Turbo's) $3.50 German

1336763 Rubber Cam Plug (B230F including Turbo's) $2.50 OEM

1389657 Plastic Flame Trap (Note: Turbo Models do not use a flame trap)
$0.50 Scan- Tech
3501707 Flame Trap Nipple (88-93) B230F,B234F $1.00 Scan Tech
(quotes from FCP Groton)
The breather / flame trap is probably plugged, causing your seal to blow out. The seal is just pressed in. It's thin metal with a rubber coating, take care not to deform it when installing. The valve cover area should be cleaned with carb cleaner, brake cleaner, alcohol or a similar solvent. I prefer to use blue or red silicone to seal the valve cover gaskt when reinstalling.

If you have the distributor in the back, I don't know what cap or vent you mean. More info please if this is the case.
