I have the haynes manual already but it is limited in this regard.

I am leaking from the rear cam seal closest to the fire wall.
I am also leaking from the rear head area near there as well.
I also have some seepage of oil in the plug areas as well.

The entire PCV system is brand new on the car. I replace the old at 300K for which it was the original setup. Plus every time I do an oil change I'm checking that part of the system anyways, cleaning and/or replacing as necessary

So all I'm looking to do is take the top covers off up to the cams.

I have the o-rings, the volvo sealant, front and rear cam seals for parts.

I've already checked the mitchell1 software and that was totally useless for this vehicle. I just received a bunch of information from AllData with pictures, but they have me diging in much deeper than what is truly necessary.

The car has just under 331K on it now. By the end of the year I will be near 350K for mileage.

look forward to any and all information I can get here. I will be doing this tomorrow and should be able to do this in about 4 - 6 hours. The Volvo mechanics say 7 hrs., but I also know that that time is overly inflated.

Thanks for the replies and help.
