We all like to have our Vettes purring like kittens with the power to roar like a lion when needed.  Ron leads us through the process of tuning up the LS1 engine so it can spring to life when your foot hits the acclerator.

0001

Tune up on the LS1 Corvette.  This is how your remarkably engine looks, prior to any work being done on it.

0002

First, we need to remove the passenger side engine cover. Notice the oil fill tube just above the yellow dipstick.

0003

This is the underside of the cover.  You can see the 4 mounting points. The cover simply pulls off, but be gentle when you remove it! 

0004

This is the driver’s side engine cover.  The silver hose coming through the cover on the right side is the fuel line.

0005

View of the driver's side of the engine with the cover removed.

0006

With the passenger side cover off, we can see some red wires. These are the spark plug wires.

0007

All eight wires look like this, wires are all or should be the same length.

0008

 For ease of removal, you may need to use a small screwdriver to loosen the rubber boot of the coil and the plugs.

0009

Here is a boot plug tool.  It can prove somewhat useful or useless depending on how confined  the area is where the plug is located.

0010

The battery panel is on the passenger side. Remove it for easier access. Although it looks daunting to remove due to it's size - you just have to pull a couple of pins and it comes off without any trouble.

0011

Here are the plugs wires removed. You can see that I broke one pulling it off. These were the original wires. Notice the aluminum heat shields on top of the boots.

0012

On the passenger side - one spark plug is visible here.  See the next picture for a better view of it.

0013

Visible plug, passenger side.

0014

These are some of the sockets you may need for this job. All are 5/8 sockets.  The first two are designed to make getting those hard-to-reach plugs out a little easier.

0015

Passenger side spark plugs, not bad for a 8 year old car.

0016

Driver’s side plugs.

0017

This is plug #7 near the firewall on the driver’s side. A little harder to get at.

0018

It's always about having the right tool for the job.  Here, I am using an extension and a flexible plug socket.  That round black object on the right side of the picture is the brake booster - in case you were wondering.0019

More plugs and wires from the driver’s side and the tools used to remove them.

0020

Make sure you have the parts before you start in case you do brake a wire and chances are, you probably will!

0021

 Parts used; not very expensive.  Before wire installation I used a bit of dielectric grease on the plug tip and the wire boot "For ease of installation and removal".

0022

Expect some bumps and bruises doing this! Oh and you will get dirty hands.

0024

Properly gap your spark plugs. I know they come gapped already but I like to make sure.  I put a small amount of “Antiseize “ on the threads of the spark plugs.

0025

I use a piece of rubber hose to install the spark plugs. Make sure you thread each plug in by hand and avoid cross threading the plugs.

0026

Improvisation at it's best.  A simple idea that works very well.

0027

New wires come with a set of numbers all the wires are the same ,notice the # 1,3,5,7, for the driver’s side and 2,4,6,8, for the passenger side.

0028

Plugs and wires done on the passenger side.  There is no need to install the aluminum heat shields on the boot at the end where the plugs are. I contacted MSD and they said you don’t really need them but I decided to install the shields on this engine.  It wasn't an easy thing to do.
