My 79 (2.3/Auto) is nearly impossible to start after it gets warmed up and sits for more than about 5 minutes. Less than 5 minutes it starts OK, after that you gotta crank it for a minute or two to get it to start until it sits an hour or two. Pushing the pedal to the floor doesn't make it start, although i don't know if it would start at all if it wasn't on the floor. When it does start it starts with a hell of a cloud of blue smoke. I don't know for sure if its valve seals leaking alot of oil into the cylinder (why would it only effect the starting when it is hot tho?) or if the carburetor is leaking gas down the intake somehow and washing oil off the cylinder walls (causing the blue smoke). It has an electric fuel pump. I don't know if it could be vapor lock. It does seem to start easier when the air cleaner is off. The engine in this car is pretty worn, there is a pretty decent amount of smoke coming out the oil cap when running and there is lots of splatters of oil along with it. It doesn't use an excessive amount of oil tho. The engine did sit for several years in a junk parts car before i got a hold of it and put it in this car.
My 76 (2.3/4spd) has the same behavior, also electric pump, but it is not nearly as hard to start. It is hard-ER than normal to start when hot after sitting a minute but no where near as bad as this 79. What do you guys think is going on? If its valve seals, how the world do I get the lifters out? (so I can get the cam out, so I can get the valve spring compressor on the springs to replace the valve seals.)
