Author	Topic: '97 F-150 exhaust studs problems
stang106 Gearhead Posts: 774 From: God's Country!... Port Alberni B.C. Canada Registered: Jul 2001	posted 05-19-2004 08:11 AM An exhaust leak and inspection revealed broken studs both from exhaust manifolds to heads and from manifolds to tubing flange. The cause seems to be extream corrosion to the studs; the manifolds also are very corroded. Nothing else on the truck is corroded, the truck is very well cared for and aside from towing a 6,000 lbs trailer is not driven hard. I searched both the recalls and TSB's and found none. The F-150 online site also has no references to this problem, but the ocal dealer has seen a few. Should I not use Ford studs again? Is headers woth the cost? Any ideas of this failure?

Anywhere we go is over mountain passes, and that also probably explains why my rear-end oil is black every year. Too bad I only have 3:55 gears, I will get smaller tires this fall. Dave IP: Logged
