Lower Intake Manifold Job
#31
Got my valve cover gaskets replaced (front needed it badly), 3 rear plugs and wires are done, tried to clean up the LIM as best as I could, but IMO it needs to be resurfaced, just not sure who near me could do it...
One of my coolant ports on the block side was full of crud, it was one that is not an actual port on the LIM, cleaned that all out...
I am just not sure what to do about this LIM....

I'd really appreciate some suggestions on this pitting issue, mainly the pitting is worst in the first pic, note this is a blocked off port in the LIM, still as bad as it is pitted I am wondering if I could try the JB Weld fix on it?
Everywhere else the pitting is mild, but there are still areas that you can see old gasket marks, you can not feel them, but you can see them, no matter how much I scrapped, or how much brake cleaner I used that was as clean as I could get it...
I don't want to have to do this job again, if it is best I'll get a new LIM.
I'd rather pay a few bucks to have it refaced, but I do not know anybody that does this.
Last but not least I could JB Weld the pitting, let it cure than lightly sand it, if I do that I'm probably buying two good carbide bits and gasket matching the ports, hell if I had the bit right now I'd probably be doing it, just for the experience of doing it...
I really hoped to get this all back together tomorrow, but it is looking like that may not happen, granted I feel the reinstall wwill go quicker than the tear down, still I have to go get some EVAP hose connectors, and I still have to pick up some upper injector o-rings..

The area is and will be surrounded by gasket material from the Fel Pro LIM Gasket, and it is a dead port, so that should work, as long as the coolant that runs up to that dead port somehow removes the gasket sealer and sucks it back into the coolant system...
I have some Permatex Ultra Black Max Oil Resistance RTV, I could use that..
Using the JB Weld is not a big deal if I need to do it, the only set back would be the cure time...
Thanks!

Thanks a lot man, so far so good.
I am trying to figure out how I am supposed to install these yellow coolant o-rings into SC, the holes are no where near the same size on the manifold or the SC.
I am looking at that DuBob vid for the 2000 GP and his manifold has a bit of a recess for the rings, I am guessing his SC does also..
I did not see any when I uninstalled it...
I read that "The OEM Gen 5 gasket has coolant O-rings fixed to it.' and my gasket does have rings around the area..

Got it all together and started it, ran for a minute then motor was kind off jumping a little, and started running rough, then it turned off, and on my DIC it said Engine Reduced Power.
The codes were P0068 & P0102
P0068 means that the Powertrain Control Module (PCM) has detected an excessive degree of variation in the input voltage signal from the throttle position sensor (TPS) as compared with voltage input signals from the mass air flow (MAF) sensor and the manifold air pressure (MAP) sensor.
OBD-II Code P0102is defined as a Mass or Volume Air Flow Circuit Low Input. The Mass Airflow Sensor (MAF) measures the amount of air entering the engine and the Engine Control Module (ECM) uses the information to determine the proper amount of fuel quantity and ignition timing.
Now my EVAP hoses from my MAP did break and I am replacing them tomorrow, I did not think that would make it run so rough..
The MAF, not sure what its issue is, unless that code happened because of the MAP code, my MAF worked fine before...
Another issue I am having is the wiring going to my ICM, I cannot get it situated so it does not have the belts rubbing on them, I tried running the wire another way, I tried pulling more slack from thee driver side of the harness, but nothing worked.
So somehow I need to fix that first, then the EVAP issue with the MAP, and then hope the MAF will run right afterwards...

ICM issue is my goof, I ran the wires the wrong way, they go under the ICM brace, dohhhhh
Still hoping th MAP and MAF issues are easily fixed, that way I can hit DMV and get my tags, then put my repairs to thee test.
I am really glad I did the LIM Gasket job, it needed it badly, the LIM gaskets were the old plastic ones, and they were damn near melted to the block..
I'm going to drive it a while before I start flushing the coolant, I want to be sure I get as much let over crud out of there as possible.
