I have a '98 Z28 and I'm in the process of changing the sparkplugs. I had no trouble changing the driver's side, but how in the heck do you get to the ones on the passagener's side of the engine? I'm using a rachet with a flex head on it. I can't get my hands or a wrench down to the spark plugs. Does anybody have any suggestions???

Thanks

 

never changed plugs on LS1, but I assume going from under the car will help you with a lot of the plugs. It's a must for my thirdgen.

 

I had to remove coil pack and remove the two bolts securing the AIR tube to the exhaust manifold and pull it up to the top of the intake out of the way, and be very patient.

The #8 plug is PITA (some people remove it from the underside), took me almost an hour just to remove it and my arms looked like I just went 12 rounds with one pissed off tomcat.

This may help...

i can change all my plugs in an hour...

pull the coil pack off..and unbolt the AIR tube...cake after that

 

Thanks for that link, I think it will help a bunch.

 

When you put that pakcs back on, leave the rear (hard to reach) bolts out. Makes it easier for next time and the fronts hold it fine.

 

u hve to remove the air tubes and some of the coil packs to make it a little easier.

 

i removed the air tube, but not the coil packs.. Wish i would have though after i cut up my arms on them. I got the back plug from under the car. I had a bigger pain putting the #8 wire on the coil than anything... All in all it took right about an hour for plugs/wires. No where near as bad as my lt1 car was when it was stock.

 

I agree 100% ........ I changed my plugs two weeks ago, except the one on the passenger side rear I could reach all from the top. The wire is a bigger pain than the plug (number 8)....

 

When I did mine, I went from under the car, with me laying on the ground right behind the passenger front tire, without the car lifted at all. The rest were done from the engine bay. I don't have the air assembly in mine, so that make it eaiser, however I NEVER removed coil packs or the A/C unit, so keep in mine you don't HAVE to do that if you don't want to

 

Good thing you dont have an LT1....change plugs on that thing and youll be in tears . Id almost rather put a clutch in my car then change plugs no the LT1 .

LT1camaroman93 gave pretty good advice for that change

 

id like to try changeing an LT1s plugs since i always hear how hard it would be.

 

On LT1's you change them from underneath. If you have a machine shop drill out the fitting on the inside of your plug socket and use a box end to turn it, it makes it a little easier. SLP sells a socket like this for $20.
