Does pinch in exhaust = overheating xj?

[ace]

I noticed that the downtube after the exhaust manifold looks about 40% crushed. Would this increase engine temp?

maybe. if it restricts flow enough.

does it look like it has been crushed or does it look as though it was made that way...I know sometimes from the factory they are that way for clearance...

like Jeremy said though, if it restricts flow enough it will cause it to over heat...kinda like a plugged cat...

I don't think it would be noticable. I do think you would notice more of a power loss or poor gas mileage before over heating.

agreed...if its 40% crushed (as you say) I think it should still allow enough to flow to not over heat but as Shawn said the Power loss would be noticeable...

I have seen Shawns exhaust, and he would be the expert on crushed exhaust.

Ya,, mine was crushed up to 80% and it still ran fine Back yard patch and she is ready to go... well.. when I get it done...

It's a 91 so I think it's probably got the lousy radiator. I guess I'll have to get it running so I can see what I'm up against.
