Had a leak and notice 6 inch bypass hose broke off some piece I don't know what it is , can you tell me
Bypass hose connects to what ? on 1995 Buick LeSabre
This is a very common problem with 3.8 engines. It's just a hose nipple that threads into the intake manifold. GM made it out of plastic and they all break. You can get a new metal one at any parts store or GM dealer. You need to get the old plastic out of the intake which can sometimes be tricky.
