Subject: Re: Spark Knock is back.... and I figured out why... And it's BACK AGAIN!!!! by bogus on 2011/10/24 0:48:43 I think I have isolated it. Both manifolds have issues. 1. Left, #1 port, signs of blow by between the layers of the gasket. 2. Right, EGR fitting to manifold, once the bolts to the intake were removed, the fitting flopped... smoke and liquid test confirm that there is a leak point there. The problem? I replace that line several years ago, and had to work around beat up threads to make it fit. 3. The bars between cylinder are bent, causing potential load and/or tweak issues. In short, 180k and they are done. Time is my primary constraint here, so I am going to take the manifolds off of bastet's new LT1 and use them for the moment. |
