I have a 1997 Pontiac which has 65 thousand Mile and the engine blew up. They said it because of they intake manifold was leaking. Has anybody every heard of this problem.

had problem repaired 1600.00 then one year later same problem. a used engine put in 2200.00 less than a year later the same problem after putting 40,000 miles on the used engine which supposedly only had 40,000 miles on it from a 1999 montana van.
