Two problems related to manifold/header/muffler/tail pipe have been reported for the 1998 Chevrolet C/k Pickups. The most recently reported issues are listed below.
Intake manifold gaskets leaking anti-freeze. Many trucks are experiencing this same problem. My truck has 74000 miles and I know of 2 others w/ 78,000 and 66,000 miles that needed gasket replacement. Talking to a dealer employee revealed that it is a popular problem with the chavy vortec motors. At a cost of around $400. 00, it is a too frequent problem. Thank you.
Intake manifold gasket failure on 5. 7 liter engine. From what the local Chevrolet dealership (w-k Chevrolet) told me, they replace 2 or 3 a week. Something to expect between 75,000 to 100,000 miles. This seems way over the line when spark plugs are expected to last 100,000 miles. Ts.
