Just about every 94-95 GT that I have encountered in my time has had a leaky rear main seal. I have had a lot of friends that had these cars, and only one that the rear main didn't leak. I was looking through the owners manual of the car the other day, and Ford says that you need to change that PCV screen (located at the back of the lower intake) every 30K miles. Well in this day and age, 30K miles comes a lot sooner than most people think. Even back in the 90's when these cars were still "new". And when I changed mine, the PCV filter screen was pretty well closed off due to being caked over time. And thats not the only thing. My car has a leaky rear main just like all the other cars I've been around. But when I changed that PCV screen in the lower intake, it stopped leaking oil. I have been driving the car for many miles, and there is no oil in the driveway, and there is no oil loss on the dipstick reading. Hmm... The guy with the boost thread blowing oil reminded me of this. Do yall think it is possible that all these rear main leaks are due to people's little PCV screens just finally getting too caked up to flow air, and then the pressure just gets a little too high and it ruins an already aging rear main seal? Cause of course the pressure is going to look for a way out. If it can get out through a small crack or something in the rear main, its going to do it.</blockquote>
