Non adjustable rockers
Anybody have issues with getting good oil supply to top rocker shaft on their fe. My one side rockers have good oil flow to shaft and down the top of pushrod while preoiling but otherside only gets oil to top shaft without dripping down pushrods. Motor is fresh and just broken in now but it has a tick from the side I think was not flowing ideal. I swapped 2 other stock rockers I had laying around and they all did the same thing . Only the one set oils proper and it doesn't matter if I swapped sides.. Any hints on a fix??

I could be wrong, but seems like the rocker hold-down bolt securing the one through which oil feeds upward to the shaft is a BIT longer than the others, too.

It is shanked (smaller diameter in the the middle) so the oil can get past the bolt and if the bolt in that hole is a regular bolt you will get what you are getting. Check the bolts on the low oil rocker.

Yes I have restrictors. Yes I have the right bolts in proper locations. Even with the restrictor removed I couldn't get the one rocker to oil proper. Oil would go up into shaft but not down pushrod like I said. I tried 2 other rockers kicking around with again no luck.

Yeah but I an swap the good rocker from either side and it works like it should with or without restrictors.

I need to read closer. You can have the rocker shaft mounted backwards in the stands and cause this. Then the holes doe the oil to the rockers don't line up right.

I messed around with it for a good 2 hours. I took a couple sets of rockers apart and checked the line up holes. I found my good rockers had the hole elongated from just a simple hole. I die grinded the other bad one to the same as the good one with not much better success other than just seeing oil under the rocker pivot arm but again no drip down pushrod. I called it quits after just not getting a good 100% fix. It was just ok

I have all the shaft oil holes facing down.
I'm assuming the tick noise is from lack of lubrication on that rocker as the noise comes from that side of rocker I knew wasn't 100% after install. The tick gets less under throttle increase and is worse at idle.
I don't think it can cause too much of a worry for damage other than just the pushrods themselves which are an easy replacement.. Is this the regular tick/ knock noise in an fe?

Could an oil passage hole in the rocker shaft maybe be plugged with crud? Before I put my assembly back together I hit the oil passages with some air to clear them out. I knew they were clear when it sprayed a bunch of oil on me...lol.
