Why can oil leaks cause a engine to heat seize?
Oil leaks will not cause an engine to heat or to seize. A lack of oil will cause it to get hot and seize which is caused by not checking the oil level and adding as necessary to keep it full. As long as the engine has the proper amount of oil it will run just fine. The leaks may cause a mess, waste of oil and money, but they will cause no damage to the engine.

What causes 1993 Chevrolet 5.7 to smoke oil under load Have changed intake gaskets and checked compresion.?
There are a couple possibilities: Check for "blowby", that's when exhaust gas leaks past the pistons, into the crankcase. If the engine has blowby it will be much worse when the engine is under a load. Check the vacuum lines, especially the lines from the transmission. You're looking for oil in the lines. Sometimes a broken vacuum diaphragm will allow oil to be sucked into the engine. In this case it could be that the diaphragm leaks oil only when the engine is pushing the transmission hard.
