Just about a week ago was thinking that my 98 XC's oil consumption was pretty decent, all things considered, at about 2K miles per quart since its last oil and filter change at around 201K miles. Then it started drinking oil pretty rapidly. Now its blowing a LOT of oil out the dipstick tube, leaving a heavy film on the top of the cam cover hood liner pad and radiator shroud. Even a run of 20 odd miles to work results in a fair amount of mess. No indication of other leaks such as the rear main seal so far, thankfully. The o ring on the dipstick is new, as is the seal ring on the filler cap. Engine is running strong and smooth, no significant tailpipe smoking.
So it looks like its time for a PVC system overhaul again...this was previously done about 3 years/50K miles ago when I had a head/timing belt and tensioner/water pump job replacement done.
Surprised this has come up again in only 50K....cars has always had frequent oil changes and I have been running Castrol synthetic 10W30 for the last couple of years since the head work. Drained oil has has never looked sludgy, and everything looks clean from what I can see under the cam cover through the oil filler cap hole. Car has done a lot of mostly highway miles in the last few months. I don t feel a strong vacuum or pressure buildup at the dipstick tube, but can see the oil mist being spit out when revving the engine when its warmed up with the dipstick out.
What's a typical cost of this job in an indie shop these days? Anything to watch out for that might be overlooked/not properly accomplished when this done? Going to the shop, needs to be done quickly and I don't have time to do myself right now because of work and other commitments. Sure sucks that Volvo's engine designers buried all that plumbing under the intake manifold. Makes changing/cleaning simple inexpensive parts an expensive undertaking.
