Does anyone see any problem areas around the EGR pipe? This is the first one I've worked on so I don't have anything to compare it to. I didn't notice any obvious cracks or breaks but, man, it had a bunch of oily tar behind the EGR pipe when I first removed TB. Looked like something you would scrape off the bottom of a crude oil tank!
Cleaned the MAF wires and removed and cleaned IAC plug. Should be good for another 150,000.
