94 3.4 Supreme Rear Plugs.Stuck at home!!!


Recommended Posts

Posted

Searched to forum cannot find and I am in a bind as I am stuck at home unable to 1: access the rear plugs and 2: put the one rear plug wire back on that I was able to get off.

 

It seems apparent to me that on the 3.4 with the single motor mount, you do not roll the engine forward like I did on my 3.1 and even my GP GTP.

 

All I can guess at this point is that I need to remove the factory strut tower brace to give me more clearance.

 

Please help or direct me to a thread that helps.

 

Many Thanks :confused:

Yah, to get to them remove that and the weatherstripping along the firewall, and then get a really long extension and a spark plug socket.

Good Good,, thanks. Had to get a ride to work but I now know my evening project.

 

New NGK iridiums and Taylor 8mm wires are my first mods.

Amsoil synthetic/ filters etc are next.

Magnaflows and tips to follow.

Sweet!

 

Yeah, the first time is a bitch after that it's easy to the plugs.

 

Unless you have the 96 intakes and then the plenum comes off. :roll:

I plan to replace my plugs when I swap on the intake manifold I've been painting. Will definately make some easy access.

I'm dredding the day i have to do plugs. When i got my new motor it had the factory plugs in it from 1991. Of course i didn't change them when i put the motor in. :bash: The motor only has about 14000 on it right now. But still them plugs have been in there for 14 yrs.

Tony you'll soon notice that the 96 plenum makes the car overall a lot easier to work on. 7 bolts and the entire plenum, intake arm, and throttle body lifts right off. I was really impressed.

 

I think it's actually faster than with the 91-93, you don't break the wire holders, and the only added cost is a new gasket.

ALL DONE!!

 

Car runs smooth and awesome.

Red Taylor wires look great.

 

Will be putting up pics tomorrow

Aaron's right. Pulling the plenum is WAY easier than fucking with a 91-95 or a 3.1/3100/3400/3800. Took me like 10 minutes to pull it off. I could probably do all the rear spark plugs in like 5 minutes. It's great!

In addition, the gaskets are cheap. My local Chevy dealer had them IN STOCK, $6 for 2 of them, which is a very reasonable price.
