Exhaust question

While I tried to look myself and be more proactive I'm stuck on this one.
I have identified all the gaskets for my 1976 2.7l oem exhaust setup , I can't find any info if I need something or the crossover pipe coming from the right heat exchanger to the left.
See pic.

I don't see any claims or bolts or anything like that but I'm guessing there is something inside that seals the connection.

Thank you

HEs are identical........

Kava,

The left and right HEs are identical. As shown in your picture, the left side (driver) HE is directly bolted to the premuffler and the right side (passenger) uses a cross-over pipe to connect to the premuffler. A good way to learn and know more about your set-up is to drop the engine and do all the necessary work specially the exhaust system with the engine out of the car.

If I were in your shoes, I would fix the oil leak first before messing with exhaust. Separating the HEs with the engine installed is quite challenging compared with the engine on an engine stand. Good luck.

Thank you Tony.
All this work includes oil leak fixes but my heat exchanges are gone so need new ones.
One i remove one heat exchangers i can see how is the cross over pipe connected to the pre-muffler but again i'm asking this in advance so i can place an order for all the parts at once.

Being in Canada, shipping, customs and us dollars plays big part in what i order and how often.

Kava,

Include your location and that would be beneficial to you. Members near your location would be a good source for assistance.

I see some dents in the crossover pipe.

Go to a good muffler shop and get it redone.

Bring the gaskets in case they don't stock them.

I did and it was 150 bucks and 30 minutes.

I think that dent is for the clutch cable end so it doesn't hit the pipe. (I've been wrong before). Yes, I'm ordering all new gaskets, everything is so rusted that every bolt either breaks or I have to cut to remove. All new bolts and gaskets all around is my pland.

Agree with you.

But the pipe in your crossover set up has been replaced/repaired before

Just throwing this data out for consideration.

I bought a fabspeed pre muffler and they sent copper gaskets. Way cool, right? Well, they leaked at the flanges.

Put a tradition gasket in. Leaked. Doubled up on the traditional gaskets and used muffler sealer goop. It is such a rigid connection there the goop is not stressed and remains intact. Eight years ago. No leaks. Double gaskets may have been overkill but I did not experience a downside..

Thank you, I will remember that during assembly.
