Hey guys,
Have a 89 k1500 5.7, when I bought it I put about a quarter of seafoam into the gas tank and ran almost all the gas back up, then filled it to about a quarter/half tank. That was about 3 weeks or so ago.
I've noticed that everytime I start it up recently the exhaust puffs white smoke for the first 5-7 seconds then it goes away. Not sure if coolant is leaking into the head gasket? Any way to tell?
Thanks again
