I have an 88 with a 305 FI engine. The engine has 130K miles on it. If the engine is cold and I start it, I notice a lot of white smoke which eventualy goes away after the engine is warm. However, after it is warm my oil pressure drops almost to 0 and the oil light comes on. This is especially true when braking. I realize the engine probably needs to be rebuilt, but does anyone have any cheep sugestions to get me by for a while ie.. thicker oil? Do you think it could be the valves, or am I going to have to rebuild? Thanks.
