Mine smokes. Those TBI's are great, easy, reliable engines.
I love mine. It runs and runs....even though mine is an oil burning machine.
How many miles can you go before you burn a quart of oil?
Also, pull off the PCV vacuum line at the base of manifold and make sure there is good suction there at the metal nipple. And then make sure the PCV valve and hose are clean and not plugged up.
Once you do all that, when is the last time you changed the plugs? If you do, look at them all and see if any of them are extra sooty/fouled. Cylinder #1 is common, which is the at the front of the engine (nearest the radiator) on the driver's side.
But my truck has really worn valve guides. They make a ton of noise too. I have leaky lifters that start to collapse at a hot idle too. But she keeps on running. No problems.
