What do i need for this?

[toenailclippers]

OK, Ive been putting off a tune-up for TOO long. I know I need the usual, air filter, plugs, wires....but what else is there? Im thinking O2 sensors as well, but ive heard that gets expesive. also would that cause my service angine soon light to come on? what about the coil pack,? IM used to working on pre-1980 vehicles, without all this fancy computer controlled crap. I say F*** emissions and everybody convert their electronic ignition over to points! Anyway, a list of stuff i would need to do an extensive tune-up would be great, that way i can get some better gas milage!

Do a complete tuneup with cap, rotor, wires, AC Delco plugs gapped properly, PCV valve, fuel filter, air filter.

Also note, might want to do a cooling system flush with a new Non AC Delco rad cap along with a transmission flush and filter change and to drain your tranfer case and differentials and fill them with fresh fluids.

It might seem like a lot, but you can do most of it yourself and your truck will be completely perfect and performing to its maximum potential and will lengthen the life greatly.

Why time to zero? I figured there would be no reason to time a new one, I thought the computer would control most of that unless the timing chain was bad or something like that.

[BlazerLT]

oops, my bad.

What brands of fuel filter do you recommend? I'm ready to change mine again, I perfer AC Delco, but none of the parts stores around here have them, I have to go to the Chevy Dealer ($20) 45 miles away. Any others you recommend or is it worth the trip and the extra money?

[toenailclippers]

where would the PCV valve be located on the engine?

[blazee]

Driver side valve cover, It slides in the valve cover and has a hose that slides on it.

When it comes to fuel filters, it really doesn't matter as long as they are changed every 40,000 miles.

Thanks, I'll just pick one up at NAPA tomorrow. You have been on this forum a lot longer than I have, I figured I'd make sure you hadn't heard of any problems with the cheap ones first.

Make sure you use a AC PCV valve. Have had problems with most other brands.

Reason for Electronic ignition over points: the normal point dwell is 30 degrees while the electronic is 45. More dwell equals better performance. OEM high performance had electronic as far back as the 1963.

[BlazerLT]

I have yet to see any real difference between Fram, Help, AC Delco or any other brand.

I haven't had any problems with my PCV valve. It's deutsch or some thing like that, I got it at Autozone for about $3. I think next time I'll buy a brand I can pronounce, though.

[BlazerLT]

Nah, as long as it rattles and as long as you replace it every 2-3 years, you will be fine.

You'll notice at an idle sometimes, the other brands will buzz. Sometimes they flow too much acting like a vacuum leak. I'll stick with OEM for my PCV valve.
