i went to adjust the valves today, but i had a very hard time find tdc. i was using the alternator nut method. i guess with this method you need two people. do you have to push on the pin until it pushes into the gearing. i was pretty stumped on how to find it. 220,000 miles and still hasn't been adjusted. i heard of a crude way of doing it. when the #6 cylinder's intake and exhaust are both open the #1 is at tdc, or close, is this correct. a little help would be appreciated. i am taking it in next week to have the injector timing done, probably 4-5 degrees advanced. thanks guys, this site rules.

 

I did mine last weekend using the method you are talking about.

Above taken from HERE

I turned the engine over a couple of times watching it before I called it good. Adjusted the recommended springs and then rotated again for cylinder #1. Seemed to quite the engine down and help the fuel milage but I wont know that until my next tank. Mine were way out, I am guessing the PO never had them adjusted.

Its actually pretty easy using the above method and didnt really take all that long.

 

thanks, ill give it a another shot tomorrow.
