Buy extra blades for the tool, you will bend a few as you learn the technique to get the blade in.

As you will see the blade is paper thin and any imperfections in it will give a false reading. Ask me how I know.

Make sure the nuts and bolts that hold the blade to the tool are tight or they may come apart will you are in there. Ask me how I know.

Car should be cold, try to get it to the workspace the night before and let the oil drain overnight.

Get some ratcheting box wrenches for the tight spots.

Don't over tighten the lock nut. Just snug it down.

TAKE YOUR TIME AND CHECK YOUR WORK BEFORE YOU BUTTON IT BACK UP.

Do NOT be worried about doing it in 4 hours or less especially since it is your first time.

Expect it to take a day. If you know of someone that has a motor out of the car or a local shop that has an open motor it's not a bad idea to take a good look at it and try your hand at getting the gauge in. It's tough to visualize what you are trying to do and is easier to understand if you've tried it on a motor that is out of a car.

good luck
