Hi all. So after a long spell of saving and so on I finally had a full set of 273 rockers,shafts,spacers and ball and cup pushrods to go onto my 318.
now in previous posts I mentioned that since the comp cam was installed it was rattly. According to comps website one will get valve train noise with their cams if you don’t have adjustable rockers.
And that’s what was going on.
Now the 273 rockers were installed last Saturday by a friend and myself. It all bolted down perfectly and we did one valve at a time. Wound down adjusting nut in rocker til you feel drag on the pushrod then go 3/4 turn and do up the lock nut! All done.
upon starting it the first time it had a lifter tap. Never had that before?! And even now after two days of running it, if I go for a drive then stop for a while. Start it again and that one lifter taps away for maybe 30 seconds before it shuts up. Anyone got any ideas as to why all of a sudden this would happen?
bit of muck in it maybe?
also after a drive the right hand side becomes a bit tappy. I can hear it even at idle. Not there when cold. I did notice that with the rocker covers off the pushrods seem very close to the tunnel they go down. I wonder if it’s tapping on the side of that but it only does it when warm? And it only seems to be one.
any thoughts appreciated
