Hi Guys,
Over the past four months, I've been redoing my GLH-T. I recently installed a completely overhauled 88 Daytona Shelby 2.2 T2 engine and bathtub head. Everything is back in the car and looking great. Here's my problem. When I added coolant, I noticed a leak coming out of the backside of the engine, in the area of the passenger side firewall. When I got a mirror and a flashlight in there, I saw the apparent source. It appears that coolant was coming off of the far right exhaust manifold bolt nut. There was no apparent coolant anywhere above the bolt, to the right or left, it seemed very clearly to be coming out of the bolt, accumulating on the nut and then dripping off the nut, rolling down the exhaust manifold and dripping onto the power steering pump bracket and ultimately onto the ground. It wasn't pooring out, but rather came out about one solid drip every couple of minutes. Keeping in mind that at that rate with the engine having never been run, it will probably lose coolant very quickly once the engine is warmed and over time. It may be helpful to know that when we were putting the engine back together, we put the threaded exhaust manifold bolt in and then used new brass manifold nuts. The mechanic that I'm working with says the brass one's have just as much clamping power and they were the smallest diameter to best fit into those little slots. Also, all new gaskets, etc., were used. So, here's my questions: 1. How is it possible that coolant would come out of an exhaust manifold bolt hole? Has anyone ever seen this before? Depending on the answer to #1, what do I do from here? Any help would be appreciated!!
