I've got a 94 mercury cougar after about 5 minutes the oil filter gasket blows out and pukes oil all over the place. any ideas?

Sounds like the pressure relief valve is stuck closed. Get your mechanic to check it.

Final(?) edit: Go to the GM dealer and get one. Last I checked they still sell them. Only thing I can think of is that the bypass in the adapter is malfunctioning. Oil filter normally only does about 10% of the oil filtering per pass (the rest simply bypasses the filter) but it's common at least among racers to modify the bypass so that the oil filter must filter all oil. I've not heard of the adapter gasket blowing out though, is it a gasket or an O-ring? The ones I'm familiar with use an o-ring in a channel to seal to the block, not a gasket. Edit: I would agree IF it's not a factory o-ring that might be part of the issue, there are various. As I recall the factory replacements are orange, and viton? Material is just as important as durometer. Dunno what others are talking about, the factory has used integral oil coolers in radiators since the 70's, starting on the Olds diesels. Not all, but they are there, and the newer vehicles even more likely. As to the pressure to blow through the cooling lines, did you try reversing the directon of airflow? (IE, put the air through the other line). I am not entirely certain, but on my external (factory 80's) oil cooler I can hear something rattle in it when shaken. I have taken this to mean there is a check ball in there that may help oil prevent oil drainback, so *maybe* (although unlikely) perhaps the flow through the cooler is one-way. And towards the engine oil pressure...it doesn't matter that it's 35 PSI or 100. If the oil filter bypass is working, pressure is NOT forced through the filter at the same PSI. IF the bypass is not working correctly, oil pressure is forced through the filter at the same PSI as the motor, which CAN lead to things like exploding oil filters, damaged filter media, etc.

I agree with the guy who said it could be the gasket. Get a very small flathead, or maybe something small and pointy, and poke around for the old gasket from a previous oil filter. Don't scratch or poke too hard, but you should be able to tell if there's something there or not.
Try that first...it's free.
Next time, put some oil on your oil filter gasket too.

although I'm a GM tech, I agree with Doug k. your problem is the oil pump . I've seen this happen on some GM vehicles and the fix was an oil pump replacement. I am sure ford/mercury work the same .

You have a chunk of something on the gasket surface. Clean it till it shines and don't tighten the filter any more than the directions say to.

Make sure that the last gasket ( ORING ) isn't still stuck on the block. This has happened to many people before. If thats not the problem then just try a different filter.

PVC is stopped up. You can put a bolt in it to hold it open till you drive to a auto parts.
