dorman 555-093 and dorman 555-021 is the freeze plugs. Some they that the exhaust side will burn through eventually, how long? Who knows. I don't think it will be for a long time though.
EDIT:::: Chit, now the freeze plug thing has me thinking, One dude said his exhaust melted the freeze plug and took the turbo out!
No, not back together yet. Have been swamped at work. I'm still debating on pulling the low pressure oil pump and having a look, that piece of steel has me kinda worried that I found in the oil cooler in the oil side. The truck runs flawlessly. So hopefully it was just something in the oil cooler. LOL!
