1995 jimmy 4.3 smokes out the exhaust smells like anti-freeze

 

Check your oil cap and see if there's coolant on it. Its probably the lower intake manifold gasket. These trucks are notorious for having them fail. Its not a hard job to replace it, just takes some time. Make sure you use the updated fel pro gaskets, that are made of metal.

 

This.

 

hoping to not have to do it

 

thanks will get on it

 

The Felpro new design, (steel/rubber sandwich type) gasket is not available for CMFI engines, (late 1995 and older). If you have a late 1995 with CSFI, then use the Felpro MS98002T gasket set. On both engines, make sure you clean & seal the lower intake manifold bolt threads, and the threads in the cylinder heads. Then follow the tightening sequence and torque specs.

 

My stock LIM gaskets lasted somewhere around 150k miles. Stock gaskets will work fine.
