I have a main seal leaking. the 72 buick 350 has 60,000 miles on it. Never Raced, maybe punched it here and there. The car has been sitting and started now and then for the past 5-6 years. I assumed that the seal may have dried up. The mechanic says there may be a deeper issue than just the main seal. I just wanted to run this buy you guys. I really don't want to spend 1900 for a mainseal and bearings. A friend said he would do it for $800.
