Hello all. I am new to this forum. I have an '06 JEtta TDI with the BRM engine (128,000 miles). I'm getting a fairly loud report back through the intake manifold. It can be heard at idle and gets significantly louder under hard acceleration. Removed the anti-shudder valve and EGR sections from the intake manifold to isolate the source of the noise, and it is definitely coming back up the intake manifold. Removed valve cover to look at cam and lifters. Without removing them, they appear to be in pretty good shape with no deforming of the lobes or the lifter tops. I've ordered tools from Metalnerd to check for timing belt alignment. Would a one tooth misalignment cause the valve train to crash into the pistons or would it just run poorly? A compression check through the glow plug ports revealed 455, 440, 450, 460 psi on the cylinders. Any help would be appreciated.
