Rust issues in engine bay
Hey so I got some rust issues on my 240 that I am not familiar with.
And was wondering what the best way to go about dealing with these issues. Rust on hood bumper on wheel well Rust above frame rail on wheel well area, will take a better pic tomorrow I was thinking tubing it but not sure how to make it structurally sound? Updated the pics other side looks worse and seems to be painted over Last edited by DurtyD; 11-05-2016 at 06:15 PM.. |

Nah those pics are fine. For the first spot, you can just hit it with a wire brush and hit it with self etching primer if it's just surface rust. Then run a bead of seam sealer along the joint.
On the lower part, you're gonna need to clean up that paint and shit and see what's underneath. That part usually rusts because people's brake lines leak and it eats away at the paint. Water gets in and eats the metal. My car had rust there, check my build thread and you'll see how I repaired it. You need to cut the metal out and weld a new section in. No, a tube front is not a viable solution for this LOL. |

and updated the pictures other side looks worse So you just welded a strip on the bottom? I thought the strut tower was supposed to have some structural integrity? |

Well I updated the pictures the other side of the sturt tower looks worse and I was talking about tubing the wheel wells not a tube front end lol You just welded a strip along the bottom? I thought the strut tower down provides some structural integrity to the car? |

the strut top plates are rusting from the inside as they sit ontop of a seam.
drill out the spot welds to remove the plates then hit the surface with a wire wheel in a grinder till the rust has gone. use the old plates to make a template to fab up some new plates then weld them back on. rust down the inner wing to chassis rail seam is quite common. use a knife to cut out the seam sealer and see how bad the rust is, you may just get away with splashing some rust remover gel over it. |

Thanks for the heads up, well the inner wing is a lot worse than it looks cause it was sprayed over on top of what you see. Doesnt it provide some structural integrity of the car? When ever I see people doing tubs they never really replace that spot? |

New chassis is in order. If you have rust issues there, you have it every where.

It's repairable, absolutely. It's not worth it though. Find a new S-chassis or import a JDM version with fewer miles and factory turbo'd setup and enjoy.

And that's just the driver's floorpan and frame rail. I've already replaced most of the engine bay and cowl. Still have to patch one quarter panel, replace the other one, the passenger floor, and the fenders. Thinking on just selling the thing as I don't have the time or money anymore.

1967 Fairlane. Running a 289 and auto. It was my wife's grandmother's car, bought new at a family dealership in Kentucky. Then passed down to my father in law, then to my wife when she was in high school. She drove it for a bit in college, then parked it. I resurrected it from a 12 yr nap. Only has 55k miles on it and little to no rust.
