So last summer driving home from work, i go over a 9% precent grade. On the was home its down hill for about 9 miles, started smelling burning oil, pulled over checked oil it was nearly empty so towed it home The passenger side cam seal was completely pushed out of the block. So i replaced it and the other side, with new dealer cam seals.
Now 6 months later same deal on the long down hill run, but this time the left side. So i think i have to much crank case pressure. I was told it could be the pcv, is that possible? If so where is it located?
Also after this long down hill run, i get back on the road, and for about 1 mile it puffs large amounts of blue smoke, witch i believe is valve stem seals, as it never does it other then after the the long down hill coast, both my subarus do this. My ea 81 for about a half mile as the 2.2 does it longer. I can prevent it by coasting in neutral down the hill but that puts alot of strain on my brakes.
So does this mean when coasting down hill, there is more back pressure on the motor, making crank case pressure increase?
