Thread: DIY Lower intake manifold gasket replacement with picutes and questions

Just thought I'd chime in a small bit of info lol The Gen V blower gasket (04+) already have the o-rings built into the gasket so those o-rings are useless. You don't want to double layer o-rings or you'll have a leak. The LIM gasket kits are made for both 97-03 and 04+, both supercharged and N/A, so if you don't use a couple of the items included, you'll be okay. Other than that, Scotty is giving you good information

Haha only reason I know is bc I gen V swapped. Other then that, I'm a 97-03 guy lol

Thanks. I noticed the gasket is different also. The previous gen seemed plastic and when I watched videos it broke coming off. Mine is a big piece of metal. Almost thought if reusing it.

Actually as I go through this process I realize the improvements they made. My LIM were intact. If they just made the coolant elbows metal to start life would be good.

Ok. Ready to continue. Next list of questions.

First. New sc gasket today. It looks dirty. Do I need to clean it?


Next question. Should I clean the throttle body?


Next what connects to this? One goes to the vac line around the blower(connected). What goes on the other?


Any other advice? New injectors? Clean injectors?

Got the supercharger on and cleaned the TB. This really is not a bad job to do. Got everything ready for final assembly tomorrow (still waiting on clip that I lost for injector)

But still need help.

I id'd where all the wires and hoses go and am still left with one blank.

This is my area of concern



It is the bracket attched to the supercharger. There is one with a vac line from the front of the blower, but does anything go on the other one?

Ok. No judgement allowed.

So lets recap. To fix a coolant leak that I could not identify, I replaced the radiator, heater core, thermostat, water pump, LIM, and elbows. I got 3rd degree burns on my face. I have spent almost $400 and countless hours on the job. But tonight I announce:

I beat the leak. I got it almost all back together and pressure tested the system and had no pressure loss in 15 min (I did release the pressure to quick when I was done and sprayed the entire engine with coolant)

Now for the other parts. I made a new vacuum line. I put back on the rail (but still down 1clip-will be here tomorrow). The rail took a lot of wiggling and an hour to put on. I put tape over all the broken plastic connectors (high temp if course)

Now for the question. And no laughing or judgment. Remember one of the first posts when I asked how to get the wire off the injector? Well, I may have pried 1 or 2 or 5 off with a screw driver and now they do not click on. Is there a way to replace them?

I don't think you understant the level of my incompetence. When I took them off, instead of following your directions, I pulled the tab up, then used a screwdriver like a lever to pop the connector off instead of pushing the button. I now have three connectors that the tab is broken and won't click in. I found a replacement on line. only 4 dollars each, but now a few more days wait.

Nothing goes on the other map looking sensor. Its a barometric pressure for outside air.

Thank you. I can now rest easy. I was about to lift the car and look under.

As far as replacing the conectors, you can just pop off the end and put on another. It takes a special tool, but not a long process. If you look at the connector there are the two opening where it connects adn two others below it. Put a small pick or tool in the bottom hole and the wire pops out. The things I have learned inthe past by breaking things I never should have.

Any special tips prior to restart? Just turn the key and let it rest for a minute until fuel pressure builds up and then crank? Going to change oil after runs a bit incase anything got in there.

Oh, and the leaking coolant elbows over time leaked onto the power wteering lines and they are rusted and need replaced. Got a quote for $1000 to replace both from the dealer.
