91 Chevy s10 pickup - When i start that truck a cloud of whitish blue smoke comes out of the exhaust pipe but after a minute of running not more smoke - What will cause this?
That would be clasic exhaust valve guides and or valve stem seals. They leak oil into the exhaust ports, when you start it the oil burns causing the smoke. when it is running the leak is so mimimal because the oil burns before it leaks into the exhaust port. had same thing on mine they had problem with valve gaskets i just did rebuild with upgrades on lifters and its fine some upgraded gasket kits…
