well i just changed my front main seal on my 96 2.4l because of a oil leak all of the sudden and it is still leaking after i changed it,the only two things ive done to it lately is i switched to synthetic oil and i removed the egr but it made the car run like crap so i put it back on, it does have an underdrive pulley but it never leaked before,dont know if any of that has anything to do with it or not,but its getting kinda messy under the hood and im tired of having to add oil all the time,any insight would be appreciated,thanks in advance,joe.
