Plugs and wires

[John Robinson]

I just changed my plugs and wires on my 93. As others have said the #8 plug is the though one to work on. Removeing the plug was not the big issue I had on this plug. I had purchased a new 5/8 plug socket with the 3/4 drive on the end. My real problem came after I put the plug in the head. I used my new plug socket and the rubber piece in it gripped the plug so tight I could not remove the socket from the plug. After about 3 hours of trying to pop it off I finally got a thorch and heated the socket until the rubber insert burnt up. So I would recommend that if you use a plug socket with the rubber insert remove it before you start using it.

Did you get all of the plugs from top or some from underneath on a lift? Thanks, Brian.

If the plug fits that snugly, maybe pull the rubber insert out and ream the inside out a little to ease the removal of the socket after the plug is in. Mine is worn enough to make it easy to remove.

I replaced the plug wires on my '94 last week. It wasn't that hard. Time consuming, though.

Pass. side was a piece of cake. The drivers side had to remove the middle inner fender well, serpentine belt and unbolted the ASR unit.

Yes I did. I put the car on jack stands and removed the front tires and inner fenders. This was partly because I was going to remove the water pump. I had the pump replaced about four years ago and I had an oil leak around it. It was a big surprise to find out that some of the bolts holding it on were finger loose. Back to the plugs and wires the best set up I think is to get a long 3/8 extension and a 5/8 swivel socket for the plugs. I used a swivel with a 5/8 plug socket.This worked but I had to fight interference from the swivel.It gave me trouble with the knuckle binding against the engine. Another option is to buy the 3/8 extensions that have the ends made so you can work off center with them.

If you are not afraid to get your hands dirty and nuckles busted this is a job that can be done by the average home mechanic (If they are patient and don't try to hurry or short cut the steps needed to do a good clean job)

Thanks, I think I am going to give it a try.

Don't forget to use anti-sieze compound on the new plugs to prevent galling those aluminum heads. I like the NGK TR-55 Double Platinum Plugs in my LT1.

And for the wires, don't forget to order new looms and wire holders, too. The O.E.M. ones get brittle from engine heat and fatigue and will break as you remove the old wires from thier holders.
