2004 XC 90 T6 AWD - Drivers Side Tire Slippage

My 2004 XC 90 T6 AWD has approx 82,000 miles on it and it runs great. I have two (2) issues I'm seeking advice on:

1. When making a left turn under throttle, the engine revs as if the transmission or gear box is slipping, but once the wheel straightens out the car continues under power. At no other time in any other condition does this occur. I can hear maybe a growling sound from the left front tire. Could the CV Joints/Drive Assembly have failed? If so, I know the dealers want about $1,800 to replace both front driver and front passenger CV Joints. If this is potentially the issue, how difficult is the job if I want to replace these myself? I'd actually just replace the entire driveshafts/joints on both sides. I'm a car nut so I have all the tools. Is there a link for how to complete this repair (pictures/instructions etc)? I don't want to have to go out and purchase a repair manual just for this job.

2. I also have a very severe engine oil leak. The dealer claims this is the head gasket leaking and they quoted me about $5,000 to fix it. I laughed. The car is worth just a few thousand more than that so I might as well buy a new car. Is this a common issue with the 6 cylinder twin-turbo engines?

Any advice or anyone who has had similar experiences and could offer advice or feedback would be appreciated.

The slip/accel thing is hard to say. Maybe stripped angle drive/bevel gear input shaft and coupler? As is very common. And if you're considering spending several hundred dollars to buy some replacement axles to do yourself, it'd probably be a wise investment to spend anoth 50 bucks and buy the repair manual. As far as the oil leak goes...are you sure it's the head gaskets? That's not common at all. What is common is for the PCV system to be completely plugged and blow out the cam seals.
