Adjusting valves while idling...

Another one of my rockers is ticking so I might just try to adjust the rockers while the car is idling. Is this a more accurate method than spinning the pushrod? I guess more than anything else Im looking for consistency.

Also what do you do on the passenger side with the alternator? Do you put it back on to run the car?

The driver side is easy, as for the passenger side it suck taking all the stuff off and then replace it back on so the car will run. By doing this method it will be messy with oil spashing onto the exhaust manifold. Fine something that will caught the oil, but be careful not to burn something like I did. I used a towel and it burn up but didn't caught on fire.

Another way is to get a second set of valve covers and cut out the top to adjust the valves and keep the oil splattering down to a min.

Mr. Gasket used to make rocker arm clips that snap over the ends of the rockers and deflects spurting oil. You still get some splash out on manifolds but not as bad. I use clips with half valve covers and it works great. I only adjust while running.

You could also just leave the alternator off while you adjust the rockers. Just make sure you remove the serp. belt and keep the wire that hooks up to the back of the alternator from arching on anything. That way you only have to remove and install the alternator once instead of twice.

Autozone sells the clips, as does Lee auto parts. I used them and there was no oil splash at all. But it was more difficult to get at the adjusting nut.

I had alot of trouble adjusting mine using spin pushrod tech. I ended up doing the 1/4 turn past clack, so loosen them until the rocker clacks, then tighten slowly until gone, then 1/4 past that. It worked, but I question the job I did.

Shoebox's website has several ways of doing it described very well. (dont know it off hand, its in his signature)

Hope this helps...

I have used the Martha Stewart method

Get some aluminum foil from the my wifey's kitchen and pull out enough that will go the length of the head. Lip the aluminum over the cylinder head, just short of the springs and keep it off the headers. Generally it prevents the oil from getting all over. It may not be the best method, but it is the lowest cost.

Not a bad idea about the foil.

The foil is a good idea. I cut up some card board from a box and tucked it all the way around the head. Did both at once put a rag on the one I wasn't adjusting worked good for me.
