Today is disassembly day #1. Going smoothly, but I have a few questions. The intake ports look weird.. they seem to have oil residue on them. The last time I pulled the intake, they looked brand new, but now they look like there was some a significant amount of oil flow. My vacuum modulator failed in a big way, and I the last time I checked the transmission fluid, I had lost a good 1.5 quarts in about 15 miles. But, this is dead black, not cherry red like transmission fluid. I inspected the intake gaskets, and I can't find a fluid trail, and although the intake gasket doesn't look all that great, it still looked acceptable. However the side intake seals both had split, and although only one appeared to be leaking, my oil level always seemed to be good. Right now, I am extremely disappointed in the quality of the GM Gaskets. My originals look better at 150k, then these gaskets at 40 miles.
In this picture, you will see some of the more caked on crap on the port, and the sludge looking stuff around the ports is just silicone I used on the install. So is the orange stuff.
This picture shows some sludge on the intake port, this is actual oil build up, not silicone. The far port looks much cleaner for some reason? Still pretty dirty though.. more than acceptable I'd think.
This is just an overall image with really poor lighting.
Here is a picture of the intake gaskets, and intake seal. You can only see one of the splits in the intake seals, but the other one looks about the same, maybe a little better looking. But they just look extremely poor.
This is the EGR hole port thingy, which is between the main intake and TB. This is where the vacuum distribution block is mounted. This is where the transmission fluid had come in through and you can see some of the red and broken up carbon build up. I'm guessing that red is what the intake ports on the heads should
have looked like?
*****EDIT***** Doesn't it show I have too much time on my hands?
