oil for a 2001 Subaru Ouybac 2.5
I have a oil leak with my 2001 Subaru outback it has 244,000 miles on it . The oil leak is coming from my oilpump area I jad my cam shafts seals replace about a year and a half ago . If I change out the oil pump seal do i have to do anything with the timing belt besides take it off and put it back on or other words by just changing the oil seal will I have to adjust the timing when i put it back together??? one more question I switch from 5w30 wgt oil to 10 w 40 wgt oil will this be ok or should i go back to the lighter wgt oil. I thought by doing this it would slow the leak down . Thanks for any help
