[Tretola]

I have a '98 12 valve and there is an oil leak from the back of the vacuum pump. I bought a 38 mm od. 28 mm id. 7mm thick viton seal to replace the leaking one but I was unable to remove the vacuum pump. I removed the oil supply line, the vacuum line, and the 2 bolts holding it in but I could not get it to slide out. It seems like the drive gear is holding it in. Any help would be appreciated. Also if you know of any other seals or gaskets I should get or any other surprises to know about.
