SOURCE: knocking or ticking in the

you are right its either a rocker arm broken or loose or it also could be a broken valve spring so look for all three While you have the valve cover off to save you coming back and looking again ... thanks Jerry

SOURCE: Have a 1990 Z71 4wd that with loud engine knock.

I'd consider some fresh, clean oil & filter change first of all, if it hasn't been done . drive it for a while providing it isn't too bad, & see if it goes away, if not get back to us.

SOURCE: putting distributor back in the right way

Okay. Turn the engine untill you have the crank mark lined up with the 0 on the pointer. At that point, look at the valves on #1 cylinder. They should both be closed, or in the "up" position. If they aren't, you'll have to turn it one revolution, to get to compression stroke. Now, you're ready to put the distributor in. Take the top off the cap, and position it in the hole, so that the rotor lines up with #1 on the distributor cap. If it's a newer one, take a close look inside at where #1 actually is because the newer ones are off set a little. Now, tighten the cap on, and hook up the plug wires, one at a time in the proper order and rotation. When you try to start it, it should run where it is, but you may have to turn the distributor slightly one direction or the other to make it start. Try your best to keep it running for 20 minutes or so the first time so your gaskets will set. ( not always an easy task when the valves aren't adjusted, and antifreeze can still vapour lock on you) If you need to know more, let me know.

Testimonial: "Thank you , but still hoping i had it at tdc to start with when i set the rocker arms but checked comp good on all but #1 and #3 "

SOURCE: my 89 chevy is making a knocking sound i just

Did you check the knock sensor located on the passenger side of the block, behind the starter, The sensor can be bad sending a signal to the Computer causing the computer to readjust the spark advanced timing causing Knocking and pinging....... or it could be as simple as bad gas. If you changed the timing chain, the gears should both be set with the the timing marks at 12 oclock for the 89 chevy K1500 5.7 350 V8 TBI OHV 16V if you set the timing at 12 oclock on the cam and 6 oclock for the valve and Distr. the number 6 is firing as number 1 you can recheck by bringing the No. 1 piston back up to TDC and check to see if your Distr. is pointing to the No. 1 Plug Hope this helps

SOURCE: it was backfire'n thru carb i removed valve cover

It is probably still getting oil, but if it is not moving as much as the other exhuast rockers chances are the cam shaft lobe for that valve is wearing away.

Same thing happened to me. As it turns out the EPA mandated that most of the anti-wear (zinc and phosphorus) additives be removed from most motor oils. This is because of emissions and because thier presence can damage the catalytic converter. Diesel oils still have all of the additives. I have been putting at least one quart of shell rotella-T into every vehicle we own. Running pure Rotella-T in the one I just put the cam in for now.
