I bought my 98 with the vortec 350 with 252k miles and have been having coolant issues since day one. First was the water neck in the intake, next the intake gaskets blew out a month later, then the water pump started leaking from one of the weep holes. After water pump change I went to recheck coolant level and it was low so I filled it to ensure the system was burped. A week after I changed it I triple checked the coolant and it’s low again...
After the intake change I noticed whitish smoke coming out of the pass side tail pipe along with a misfire on cyl 5. Gave a tune up and there’s a small mid on start up but smooths out and goes away. The white smoke is pretty heavy, like when it’s below freezing out it takes the exhaust a bit to go “clear” per say and it’s 75° out and when you drive away it looks like it’s super cold out. If that makes any sense. It clears up after the engine warms up to temp and been driving for 15 mins or so.
The tail pipe it’s coming out of is coming from the drivers side of the engine, even though the tail pipe is exiting on the passenger side.
I assume it’s the head. I haven’t preformed a compression test or leak down yet. Oil isn’t in the coolant nor coolant in the oil. It’s the only conclusion for the coolant disappearing I can think of.
What are the other signs if any?
