crank case pressure

[tariqzai]

Update!! Few days ago I added some head gasket sealant to the coolant, I drove about 1400 miles after that, 700 under a very light load and 700 empty, did not need to add any coolent, also the coolant stays static in reservire now, I inspected crank case filter and it was clean except few drops of oil at bottom of case, no sign of water or colant in it, I had drilled hole in new filter so filter looked pretty untouched. I think the problem is fixed for the time being, I did the exhaust gas test again and it came negative too. The only worry I have now is I think the pressure in reservire stays more than normal, it takes longer than normal to get pressure released when taking the cap off, even if truck been sitting with engine off overnight.
