exaust leak

[chapter]

There is a exaust leak at the Y joint. We clearly see that the gasket is gone... The pipes are rusted but solid enough. So is it possible for a muffler shop to change only the gasket without changing all the Y????

I had a hard time with the gaskets on my '87 when I did the exhaust. It seemed like once I repaired one another would start leaking. I ended up using Permatex ULTRA COPPER Hi-Temp RTV Silicone Gasket Maker for the connection between the header and Y-pipe. Works better than any of the replacement gaskets I tried. Its available at most any auto parts store but here's a link so you know what to look for.

If you can get to the bolts and pull the flange apart you could prolly repair it yourself.

 

Good luck.

I would think so. Although they're liable to give you the standard disclaimer. The hi-temp copper is good stuff as well but you'll still have to split the joint. Head for the sawsall and either a gasket from the parts house or a tube of copper and some nuts, bolts and washers. Wear some eye protection if you choose to do it. There is going to be a lot of junk falling while your working on it. Eyes the pair without a spare.

Ditto to both of the above; ultra copper is great when used with gaskets, it may be problematical to get apart, and use safety glasses ALWAYS ! I didn't have a manifold leak until I broke open the Y to remove the tranny for the clutch. It started leaking 2 months later... Different stress loads I think.

Perhaps a shop will argue to change the y pipes, but the difference in labor and the new exhaust parts may well equal additional issues in the future; they will have to gaurentee it. Depends on the price... Update us...

It depends on the condition of the piping and your budget. If you can afford to have the affected exhaust pipe replaced, it's all good. Otherwise, do what you can with what you have.
