So I have a 2001 v70 2.4t wagon. So there's not a massive oil leak but enough to leave the dipstick dry by morning. I've narrowed it down to cam seals based off the amount of oil in that area. I'm steal cleaning down the block from under. The drain plug had no gasket also I'm gonna check oilpan just to rule it out. Any other gaskets or seals would you recommend before I put oil back in?

 

Dipstick dry by morning? 2 quarts a night?

If it's leaking when it is running and the timing belt is wet - (not leaking 2 quarts from the cracked oil pan when sitting)

The cam seals will leak if the PCV system is clogged - and a 22 year old Volvo will have a clogged pcv system - unless that job has been done recently.

The VVT gear can leak also unfortunately.
