Manifold leak detection V70-XC70

Problem solved! The intake manifold was leaking. I completely tore the whole thing back down tonight and redid everything. I can't believe I made such a dumb mistake. I had two vacuum leaks, the hose that attaches to the throttle body rolled over when I installed it and the manifold itself was not tight. Tonight was the third time I have pulled it apart since Sunday. The entire job tonight took me 2.5 hours, and I spent around 30 minutes getting the two bolts that support the intake manifold from the bottom back in. It took me over eight hours to do the complete job the first time. This job could be done easily in 2 hours by somebody with some experience and the right tools. I would recommend taking the two bolts that secure the intake manifold from the bottom out by accessing from the top of the engine compartment and using a box end 12mm ratchet wrench. I spent hours trying to get them out from the bottom the first time, took me around five minutes to get them out tonight. Also a 1/4" drive socket set with a universal would be perfect for getting to the intake manifold bolts on the head.

I'd say overall, I am very happy I did the job. I've been using mobil 1 since I got the car with 50,000 miles on it, and it has 160,000 on it now. There were no clogs in the tubing, oil box or even the nipple in the fresh air line. I didn't have the tell tale puffs of smoke from the dip stick hole. However, I was able to replace all of the vacuum lines on the car, they were all rotted. Plus I stumbled on the exhaust cam seal that had blown out of the head, causing the massive oil leak. Price for all the part was reasonable-I got the ipd kit and it was $115 delivered. I purchased a handful of extra clamps and some vacuum line at the local auto parts store for about $15. I purchased cam seals from the dealer and got them for a bit over $9 each using my mechanic's account and bought the turbo return line gasket and seal also. My oil leak has been greatly reduced. The performance improvement is unbelievable. The car pulls hard to 6000 rpm (I have an upsolute chip) running regular gas. No misfires, no bucking, smooth power all the way. Real fun to drive again. Thanks to all for the help and suggestions.
