changing spark plugs

[alex1989]

Just rolled over 90500 on my car.. I believe i still have original plugs in it.. So i am going to change them. I was looking and the driver side looks doable any tips or tricks for the passenger side? What kind of entensions or adapters do I need? Any preferences on plugs? Also how many quarts of oil do our ls1s take, I am about to do the first oil change since I bought the car as well. Thanks!

for the passenger side, remove the coils and valve cover and it really opens up that side, you wont need any special adapters or extensions. just the regular 5/8 socket and a small extension. and for the plugs i use NGK TR-55, theyre the best for LS1's. and for the oil, she'll take up about 6 quarts.

Thanks!!

Thanks just answered my questions at the same time. I bought MSD wires and NGK TR55GP but they have 2 or 3 different TR55's. Iridium, Platinum are the ones I bought and another one.

Whitch one is the one to use? Will the Platinum do or do we have to put the Iridium?

[Mr. Luos]

I use the NON-iridium ones. But they don't last as long.



Takes me about 45 minutes to change the plugs now. Would be less, but my stupid temp. gauge sender is right over #8.
I recommend a 1.75" extension. God's gift to the LS1 when changing the plugs.

noooooo dont touch the valve cover thats gona leak later, just the coil pack all togather and the exhaust hose move it to the side depends how small are ur hands u may need to remove the heater hoses from the back use a reg pliers and bend them towars the back thats pleny of room good luck!!

[V8MUSCLE]

the only thing i took off was the hose coming out of the exhaust. the rest i could get to fairly easy. for the last to go from underneath, theres plenty of room.

remember after you get the wires off to hit it with a air compressor to blow any trash out of the hole.

Had mine off at least 50 times.
No leaking.

oh my.. u have changed ur plugs 50 times??? all im sayin thats kinda to much work in vain no??? i think removing the coil pack is more then enough

Takes me 2-3 minutes to remove the valvecover. Saves me at least 20 minutes. I have large hands, and it frees up just a little more space to reach #8.

Full on plug change (including removing coilpack and valvecover) takes me 45 minutes.


I change my plugs every year. I have had the valvecovers off many times for other things. Just to inspect the rockers and springs 3-4 times a year.

i've had mine off plenty of times as well and no leaks here... just dont over tighten it! and tighten it evenly! if not, thats when the leaks come.

well yea you could go underneath.. till you get lt's!
otherwise a real good method. i used it myself.

[alex1989]

thanks for the advice!!

The 98 valve covers are really bad. LOTS of bolts. I took off the back two coilpacks and used a swivel socket. First 7 is under 15 minutes... the rest of the time is fighting with number 8.

i found the best way to change the #8 is from underneath the car

i've got pretty big hands too

[VTXrider]

I think most people will tell you to use the copper NGKs (the cheapest) and just change them more often. This is not just the people saving money who say this, but seems like 80% of the people.

Not with my headers and exhaust. Can't get to it.
Oh well, I have my method down pretty good at this point.

Back to trying to find the AR103's for Slowass.

no ac delco's?

[Mr. Luos]

no ac delco's?

The price was through the roof....
$58 for the set.

The AutoLite's are as good (if not better) and are about half that.
