Dave Hunt and other victims: Just got 2-OH! started this weekend, still runs shitty, but that's another story... What I'm bothering you about is your exhaust leaks...I assume you had a bad seal between the heads, the copper gaskets and the manifolds... How did you know...and a quick and dirty on how you fixed em'...The nuts are torqued correctly, and honestly, I would hate to torque them any more...Afraid of breakage... With the car running, I get a pretty good downdraft of hot air if I hold my hand under the manifold area...Not scorching enough so that I have to move my hand but hot none-the-less...But is that blow-by or just the cooling fan/tin/ducting/cooling air moving over the cylinder heads doing it's job and exiting under the car... When running, it doesn't backfire or spit...How can I tell if the manifolds are sealed or not... New gaskets, new nuts, old manifolds but they fit right in, fresh head rework with a couple of new studs... 2-OH! |

I did all of the above and still had leaks. It always popped on decel at the same stop sign about a mile and a half from my house. It didn't leak when cold and it didn't leak when hot just on warm up. I was so pissed the next time I had it in the garage I said to myself I'm either gonna fix it or bust it so I grabbed the HE's and started shaking them around. Enough so I could see the engine moving on the mounts. I tugged and pulled then tried to take up a little on the exhaust nuts. I got a little on a couple so I the whole thing until all were snug again. No exhaust leak. I supect that stuff was cocked a little and wrestling with it loosened the binding. Some people wrestle other people, some wrestle gators, I wrestle cars Good luck Dave |
