does anyone have a copy of the under plenum dvd that Marc sells? I need a refresher course.

no one has one they'd be willing to loan? I'd be happy to pay shipping both ways and a deposit if you felt necessary

I've been meaning to buy one, but havn't gotten around to gettin it. I've had my plenum off maybe 6-8 times and rebuilt my complete secondary vac system. What do you need to know? I havn't had to work with the injector's yet since the car came with RC's and has been flawless that way. Do you have a FSM or an LT-5 engine suppliment?

Re: Marc Haibeck under plenum dvd...
 

have both the fsm and lt-5 supplement, this also isn't my first plenum pull but I haven't had to do it in probably 8 years so i'm more then a bit rusty. I know I have to drain the coolant, disconnect the fuel line, map sesnor...something under then plenum...my father thinks it's a clip and I think it's a bolt...and there's a c clip somewhere that I have to be careful not to drop...

Before you pull the plenum, get a set of new gaskets. I used the thicker versions from Jerry's Gaskets. Please know this does not cover removal of the injector housings.

1) Disconnect the 12v battery

2) Remove the air coupler from the air horn/throttle body

3) I drained the upper coolant reservoir to below the tubes with a turkey baster or you can use a siphon hose.

4) I put a good rag under the hose connection at the pass side rear of the plenum when I disconnect it as coolant usually drips some.

5) I Disconnected all the outer plenum hoses and electrical connections. This includes: PCV lines out of the sides, MAP sensor hose, IAP connector, etc . These are all visible.

6) I used a piece of cardboard about the size of the plenum (like a template) and marked the plenum bolt holes and numbered them so that as I removed the bolts holding down the plenum I could place them in the corresponding hole in the cardboard. Or you can use plastic baggies to place all the hardware you remove, labeling each bag to make putting the bolts back on easier and you won't lose any parts.

7) I used a hammer to prop up the front of the plenum so I could disconnect the ignition module and front vacuum line. You can also use a wood board or block. If you have help, they can hold it up for you. Be careful as the clips on the connections are old and can break.

8) There are (4) electrical connector's [(2) in front and (2) in back)] on the ignition module under the back of the plenum. There is also (1) vacuum hose under the front of the plenum (under the air horn) that needs to be disconnected as you lift the front of the plenum up.

9) Unbolt 1/4 bolt in main DIS connector at the rear of plenum (it will stay in the connector itself)

10) You do not have to remove the throttle cable. You can flip the plenum and lay it down on the driver's side tire

Take your time and use the manuals for reference, especially for re-installation. The plenum bolts are torqued to 20 ft lbs in a very specific sequence shown in the manual. (PLEASE ADD SEQUENCE TO POST)

It's not really that big of a job and you can do it yourself if you just take your time. The hardest part for me was holding the front of the plenum up to disconnect everything underneath. The wooden hammer handle about 12-14 inches long worked perfect.

Or, better yet, cough up the fifty bucks to get one for yourself. Show that skinny guy some respect. He does a lot to educate the rest of us about the LT5.

Like you remind us every time you post, "It's not the car, it's the people."

Re: Marc Haibeck under plenum dvd...
 

I hate the brittle old plastic. Those connectors always break. Is there a good technique for securing them again afterwards, maybe a rubber band or something? I figure the pressure and friction will hold it together anyway, and has so far.

Re: Marc Haibeck under plenum dvd...
 

Most important, DISCONNECT THE BATTERY before you do anything!!

Those plastic clips will break!! I find that the plugs will stay secure anyway, as long as you plug them in all the way.

Bob is right about supporting each other. But I also know that $50 bucks is not chicken feed. I am sure it is worth it.

We like to take care of one another if at all possible,thats what we do here.Stick around long enough,you just might need to borrow something sometime.

That was the point of the post. I'd be very surprised if he bought the DVD and found that he didn't save himself at least $50.00 in time and aggravation.
I don't know of anyone in the hobby that contributes their knowledge of this car for free more than Marc. So when he packages that expertise on a video to help you do a good job, why not let him make a few bucks from it.
Just a thought, not meant to offend anyone.
