Ticking started a few weeks ago.
383, aluminum heads, Schumacher headers.
I changed the collector gaskets recently as one failed before this tick. I used a straight file on both sides and a little copper spray.
No leaks at collector or heads, no signs of a leak on either side, no air flow felt anywhere.
Ticking started a few weeks after I replaced gaskets, but sounded different.
A mechanic friend listened to it running, told me to bring each cylinder to tdc and push down on the rockers/lifters.
If there was a bad lifter, or lobe, I would be able to push down fairly easily, or the pushrod would be loose.
No can do.
Pushrods spin at tdc, no signs of being bent.
I don't see any wear on the spacers between the rockers, or on the brackets under the shaft bolts.
There does seem to be more side to side movement on #7, which is in the area of the ticking.
I thought for sure I'd be swapping a lifter or pushrod, now I'm stumped.
