[QUOTE="xtreme_exploder, post: 16212567, member: 153138"] Built a new motor for my car, and I had the heads completely worked over by Fox Lake. New guides, exhaust seats, valves, springs, CNC porting/chamber work, etc. Everything looked good, and the car runs great. Only problem is the driver's side head/header area makes a pretty annoying mechanical ticking noise. It's not an exhaust leak. The volume is steady and independent of engine load, but the ticking varies with RPM. It's most audible inside the header tubes when you go under the car, and there also seems to be some of the noise coming from inside the valve cover. When driving with the windows down, you can here the ticking echoing off of everything. I haven't been able to narrow it down to a specific cylinder, but my hope is just a bad or clogged lash adjuster. Those are the only used parts in the heads. Anyone have a good idea of what it could be? I'll call Fox Lake too to see what Ron thinks, but I just want to reach out for other opinions/experiences. [/QUOTE]
