Its awesome to finally be apart of the gadgetman land! I just recieve my personal license kit yesterday, and have already started on a project. I wanted to post sooner, but I was having internet trouble. My first project is an 8 passanger, 1/2 ton van-95 Ford Chatteau. It has a 5.8 L engine and a dual port TB. The TB was a pain to get at. I should have started on the car first. Oh well, I already have the TB out. Their was a lot of carbon build up. I haved it all cleaned now and just about ready for the groove here in the next day or two. Any suggestions or comments for a newbie would be greatly appreciated, but I did have two main questions. First what are some good brands of rotary tools to get to do the groove? and Does the throttle/idle srew need to be turned all the way out? or do you do the groove where the idle screw holds the plate at? the plate is pretty well closed, it might move a little more if i back out the screw. I hope to post pictures tomorrow. Oh yes!...almost forgot...I'm still a little lost with how to reroute the PVC valve or even what it really is. I don't want to cap off the wrong hose! Thanks for your time and any suggestions.
Have a gr8 day!

Hi Andrew,

Welcome to the team.

What will give you the most advantage is to read all the Documents here on the web site, browse through the forum entries and soak in as much as you can. Also, on Youtube are the Gadgetman Groove channels, lots of information there too.

As far as tools

Dremel 4000 rotary would be the best bet. More torque than the 300.
If it is more comfortable for you, get the flex shaft that mates up with either of the above tools. I find it much easier to handle than the Dremel itself.

Also get yourself a vacuum line tester if you don't already have one.

An OBD II scanner will come in handy on newer vehicles

On the idle screw, yes, close the plate completely. When you reset the idle the plate will open to the edge of the groove.

Here's your PCV valve

Welcome to gadgetmanland.
If possible fill your tank and drive gently for a few miles before you groove your car note the miles then fill your tank again note the amount off gas you can fit in tank. Repeat this mpg test after groove . This is valubale info for sceptic people. You shuld have good results as the gas will vapurise more when travelling with the groove winds. Looking forwards to follow your progress. Best wishes from sweden

Thanks for the replies. Here are some of the pics of the van and project so far. The TB is out and cleaned. Can u guys tell which line is the PVC? Thanks.

Hi Andrew,

If you use the link in my earlier post, that is to a Youtube video where the gentleman is actually showing the route and location of the PCV.

The short version is, left side of the engine (passenger side) to the back, down below the valve cover. The hose actually routes across to the drivers side and forward which is wheree you can deal with it.

I've made some notes for your TB on the Idle Air Control




It looks like the throttle plates open from the bottom. If they do open from the bottom then it will just be a matter of reducing the airway from the IAC to a 1/8" dia. hole. If you remove the IAC from the TB you can fill the hole with JB Qwik and drill a 1/8" hole through it. (this also depends on how the IAC functions, physically).

If the throttle plates open towards the idle air pathways ( A & B )then they will need to be rerouted.

Piece of cake...
