1998 Volvo S90 Q&A
1998 Volvo S90 Question: oil leak
Usually its the valve cover or the oil drain plug and start by putting a piece of card board under the engine area and that will help zero in on the location - Valleyautotech
Like Valleytech said, try to see where it's coming from. These engines generally leak from a few places, oil cooler, rear main seal an the crankcase breather housing to name a few. - Bret Bodas
Grandaughter pulled in to have her oil changed and mechanic told her leak was coming from around the camshaft area. Is this an expensive repair? I know difficult to estimate without seeing vehicle.
