RE: Valve train noise
ORIGINAL: Nike2141
Ok, I have read just about every post about the solution for valve train noise issues, and I still cant figure this thing out. I have a set of AFR 185 heads w/1.60 ford rockers. I checked the push rods and discovered they are the correct length. I also changed the lifters for a brand new set of motorsport lifters. The cam is a launati custom grind fyi. We adjusted the rocker arms exactlyas the tech from Air Flow Research advised. Now I know these heads are going to make a little more noise than a stock set, but this is crazy loud. The pistons are notched for valve clearance so thats not the issue, and the rocker arms are not striking the valve covers. Anyone have any insight on this? Anyone have a set of these 185s with a similar problem? Also the other thing is I noticed a small amount of oil in the throttle body, I had this same issue with my 95gt, but this seems to be a little more oil than before. Any advise would be great.
TY

BikeBoy check this out....I had the same issue as it sounds like your are having on my 306 I built a while back. Mine was LOUD as hell like a bunch or rocks in the motor, or if you put on your rockers all less than finger tight and started the motor.....thats the noise mine made sounded like crazy valve train noise all across the board each cylinder every rocker it was nuts...I took to every builder/shop I knew nobody could put a finger on it......and I did all the basics like you...mine was NOT hitting the valve covers....PTV was good....I readjusted the valves four times. 1/4 turn 1/2 turn 3/4 turn 1 full turn....nothing same **** everytime....primed my lifters to all hell....and my motor read GOOD oil psi....but dude the noise NOT normal...people were like rockers are "loud" well I can tell you they are not louder than flowmasters.....is this the issue your having? I got soooo pissed I ended up pulling the motor and its sitting in my garage...that piece of $hit....

RE: Valve train noise
Dude no way? You know what bud? I had a thread on here a while back about this issue....a lot of us were going back and forth about what it could be, what was checked etc. I gave up when I went through all those options and the $hit box still was making that ticking/knocking/WTF.......I did everything under the sun....I used the pushrods that came with my topend kit. Then said F this and went back to stock....but that created a little guideplate interference so...I dont know that was one of my last measures when I had nothing left to do......like I said I took it to a bunch of shops/and builders...they were like you adjusted your valves wrong...I was like no...I've done them before many times with no issues....this time? Then they said your lifters suck.....I was like they are new.....??? And primed....but hey check this out this is what one guy told me....all of you let me know what you think for our sake....
Ok so this one builder told me sometimes depending on lifters/castings/etc. there maybe a need to "clearence" your lifter by grinding or etching away a portion of the lifter to allow "more" oil flow to oil galley. Because the galley is allowing "some" oil to flow through but not enough? Therefore not allowing the lifter to pump up "all the way"

RE: Valve train noise
If his is like mine...it cant be pin-pointed because it sounds like hell at every cylinder front to back of the valve cover....if it could be pinpointed the "problem" could be fixed...then you know "where" the issue is....
