Well-known member
Hi, I'm new to the site and to Inlines.I have a 66 Mustang coupe with a 200 in it. Mods so far are pretty simple:
- Pertronix ignitor and flamethrower coil
- Carb rebuild(autolite 1100)
- Dual outlet header and duals from Waldron's
Recently I have developed a valve ticking noise and I'm trying to figure out the fix, without going too deep into the motor. I'm kind of a rookie at engine work, but I'm pretty handy and typically understand how things work if explained.
So far I have:
-Ran some Marvel Mystery oil in it to try to clear out any clogged oil passages, etc
-Pulled the valve cover to check for good oiling and anything obvious(Bent rod, Etc)
-Rockers are not adjustable
-Checked the exhaust for leaks(has classic inlines dual header)
-Did a compression test(all were within 10 lbs at 105-115)
Also, I was recently forced to buy 93 octane gas, the station was out of 87, and I was out of gas.... Could this have contributed to the ticking noise I'm hearing?
I was considering pulling the head to replace a (minor) leaking head gasket anyway. So I was thinking this would be a good time to go ahead and do a valve job. I am considering the 1.62 ratio rockers when I put it back together, to give the engine some more air flow and allow for future adjustability. Its a stock engine now but I plan other upgrades(not sure what just yet, maybe 2v carb - Probably no cam work), this is why I'm thinking about the 1.62's now while the head is being rebuilt.
Looking for opinions on the valve noise and what is likely causing it. Also looking for someone with experience using the 1.62 rockers to see if there is a noticeable difference in performance.
Thanks!
