Big oil leak front of 2.5t - two cam seals and front crank seal - any other seals ?
I have a big oil leak in front of my 2005 XC90 2.5T. Not really sure where its coming from but the timing cover is covered with oil and so is the timing belt. Its going through a quart of oil every 2 months. From what I can tell, there are 2 cam seals and 1 crank front seal. It looks like the front crank seal is fine but the cam seal may leaking. The area around the turbo is dry and so is the turbo return oil. With 160,000 miles on it, I will replace all 3 seals up front.
Is there any other seals in front beside the two cam and crank seals?
Since I will need to remove the cam gears, is this the tool I need?
There are two cam seals one for VVT and one without VVT. How can I tell if my 2005 XC90 came with VVT ?
I will be getting seals from RockAuto along with other brake brake parts. Just want to verify that I get correct seals.
What are the correct part number for the cam and crank seals?
you may have a leak in the VVT gear. If you pop off the timing belt cover, the standard cam gear is just a gear (thin, no extra bits), the VVT gear is a bit more elaborate. pretty much all volvo engines after 99 have VVT on the exhaust cam, so a quick look with the cover off will tell you if both gears are the same.
Before you assume you have leakly front cam seals or a front main seal, you may want to test your PCV pressure as a clogged PCV system can force oil out through the seals and you'd want to fix that as part of the process.
There's also some good Youtube vids on the process for setting the VVT gear timing - they rotate like 20 degrees against the cam (which is driven by oil pressure - thus the risk of a leak) so when reinstalling the timing belt you need to follow the procedure to correctly load the hub.
yes the glove should suck in or fluff in and out - but should not inflate and stay inflated. As to the seals, I'd clean the area and then run for a few days and check again to make sure you can trace where the oil is coming from. My guess is that it could be the VVT gear or cam seals. I'd be really surprised if you have leaks in both the front main seal and the cam seals, but repairing the VVT gear or cam seals will require removing the timing belt so you can do all three front seals at the same time for just a minor extra cost. Also unless the timing belt was replaced recently, you'll want to have a new timing belt, tensioner and idler installed. If the car is already on its second belt (say your're in the 150K+ mile range) you may even want to consider doing the water pump if you plan on keeping the car for a long time.

I did complete timing belt, water pump, serpentine belt 2 years ago and now have 160,000 miles on it. I did notice that the timing belt on the Exhaust VVT is on the edge so the cam gear may be worn out. Please see my picture below. I am going to remove the timing belt and see how much play it has.
