As you all know I just got my rebuilt 302 running. I have roller lifters and Harland Sharp roller rockers. I adjusted the rockers with the intake off when I built motor. I turned the motor over until the lifters were all the way up, then tighten the nut till I felt the push rod was barely turning. Then I turned 2 turns and locked the nut. The reason I`m asking this question is because I hear a ticking noise. Is that normal for my set up? Thanks, Tony------------------

2 turns!!!  1/4 to 1/2 turn would be more like it! DO NOT RUN THE ENGINE UNTIL YOU CORRECT THIS!!! ------------------

I guess I should've piped up sooner... not having ever run a roller, thought maybe they took a different preload  I hope that 'ticking' isn't what I think it is

Sorry Steve, I was confused when I posted that I turned the nut 2 turns. I remember now that I just did 1/2 turn but where I did mess up was I did it with the lifters all the way up when they should have been down. Is that correct?Thanks,Tony------------------

Tony,
To adjust Hydraulic lifters they should be positioned on the base circle of the cam, meaning the valve should be closed. There are many ways you can do this. My preferred way is to have the harmonic balancer marked every 90 degrees. Starting at TDC, top dead center of #1, check the position of the rotor in the distributor to make sure. Ajdust #1 intake and exhaust, rotate the crank 90 degrees, adjust #5 intake and exhaust, rotate another 90 degrees and do #4. Go all the way through the firing order. This way it takes the worry out of missing a valve adjustment. There are other ways, but I'm old and this way is easiest on my feable mind.Mike

Phew! You scared me there, buddy!  Kcode adjusts his valves the same way I do. A lot of guys like to adjust the intake as the exhaust starts to open and vice versa, but the way kcode and I use allows you to just turn the engine three times. If you did adjust the valves with your lobes up, there's no doubt they aren't adjusted right. These methods of valve adjustments are all preliminary, by the way. The best way to adjust them are with the engine running. You back them off until they clack, then slowly tighten them until the clacking goes away, then tighten 1/4 - 1/2 turn further. {Some guys prefer more} Even though it's messy, it's the best way. There are oil restrictors you can put on the rocker arms temporarily, but they often don't work on roller rockers. An oil valve cover with holes drilled to access the rocker arms nuts works real well. ------------------

OK I did them with the valves closed and it sounds alot better now. No clacking noise at all.I was putting on my air conditioner bracket today and had to take a few bolts out of my water pump, so I had to take my fan and pulley off to get the long bolt off.I was taking the bolts off my fan blade and I dont have much room so I was scraping the radiator just a little bit and I be damn if it didn`t spring a leak.If it aint one thing its another.Oh well it will be worth it when I get all the bugs out,I hope.
Thanks,Tony------------------
