Please help with ticking noise
Ok so here's the deal. My buddy and I've been trying to figure this ticking noise out for over a year, on and off as we get frustrated. For the life of us we just can't figure out what it is. We upgraded the top-end and have had this problem since first start-up. The engine specs are as follows:
-69 383, bottom-end has about 10k miles on it. We did not touch rotating assembly.
-440 Source heads installed out of the box
-Hughes adjustable rockers
-Hughes pushrods
-Comp XE275 cam
-Comp flat tappet hydraulic lifters
-Comp timing set
-MP oil pump
-MP fuel pump (reused old pump rod)
-MP windage tray
-Eddy Airgap intake
Is that enough info? If not I'll be happy to elaborate on anything about this combo.
This is what we've done so far.
-Checked, double checked, and triple checked the rocker adjustments.
-Pulled intake manifold and inspected for a wiped cam lobe. Not saying there is no way, but we didn't see any signs of scarring or anything like that on the lobes or lifters. Though neither of us have seen a wiped cam.
-Replaced lifters with new Comp units.
-Replaced header gaskets.
Both of us have gone over this engine high and low with a stethescope trying to locate the problem. We've isolated the tick to cylinder #6, or atleast that's where our best guess it. We did not hear anything on the side of the block. The intake port for cylinder #6 is the spot where we can hear the tick the loudest. Here is a pic of the location where we believe the tick is originating. Or atleast as close as we can get.
Do you guys have any ideas of where we need to go from here? This tick is so loud you can hear it from several feet away with the hood closed and it's driving us crazy! Any help will be greatly appreciated.
