Toyota Repair: 1990 toyota pickup, pan gasket, gasket kit

Question
22r 2 wheel drive carburated. It has 185,000 still runs real well. I performed an oil change and put a new alternator belt because the old one was oil soaked and starting to squeal (from a small oil leak for about 2 years). Now I get about 30 miles to the qt of oil. I replaced the oil pressure sensor, to no avail. PCV is dry and ball works.the fan clutch blows it all over the passenger side of the compartment and it is a huge dripping mess. I thought maybe the crank seal is bad. I purchased a front end  gasket kit that I will install this weekend. Any other sources other than the pan for a leak? Thank you!

Answer
Removing the timing cover and replacing the gaskets and the oil pump seal should take care of the problem, it's not uncommon for the gasket to leak where the oil pressure port is, this is where the oil passes from the pump through a passage into the engine block. It may be a good idea to replace the oil pan gasket at the same time because the front part where it contacts the cover may break when removing it, if the oil pan is not leaking there is a shortcut we used to do which involves removing the front part of the oil pan gasket and cutting the piece from a new gasket to fit onto the oil pan, some sealer to fill in the gaps, it's a little tricky but saves some labor, another thing to lookout for is the headgasket where it makes contact with the top of the cover, in most cases the cover can be removed without damage to the headgasket, if some of the sealing material should come off you can use some PVC type sealer to seal it, there is no pressure on those surfaces so sealer will work ok to keep the oil in, do not forget to remove the 12mm bolt directly under the cam gear,it goes through the head into the block, there is normally a pool of oil that hides this bolt.
