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! |

QUOTE(vsg914 @ May 24 2004, 01:05 PM) Engine cooling air will be a constant velocity. Exhaust manifold leaks will have a "beat" that will quicken with engine rpm. yupp, he's right ^^^ ... cooling air is a constant flow at constant rpm, exhaust leak will oscillate ... Andy |
