Can anyone tell me what this orange sludge around my oil cap is? I just noticed it when I changed the oil for the first time because I just bought the truck. It also smells like exhaust fumes.

 

Just that - sludge. Usually a result of short trips, with insufficient warm-up.

 

Wouldn't normal sludge be like brown blakish? Is this bad for my engine? Its an 06 with 104 thousand miles.

 

orange is the color of two things in an around the cyl, head.antifeeze and rust. neither is good outside near an engine opening. pull the valve cover if it's rusty sludge or sludge mixed with antifreeze. your gonna need engine work if none exists your one step better off. next look at your dipstick, don't laugh it should look like oil brown or black anything else and again your in for repairs.
no normal sludge is grey or blck and you can use a fork too scoop it up,.

 

Well I changed the oil and the oil was black. And then when I checked the stick after the oil change it was normal oil brown.

 

Here are some pictures

 

thats good/ oil pressure good/? then run it and enjoy,I wouldn't beat on it though. have fun enjoy the mods in this forum and welcome btw we are all ;picture ****** where are yours??1!!

 

Well mine is pretty much bone stock so the truck is just a 2500 big horn. The oil pressure is fine.

 

So?! Got a camera phone and an e-mail address?? If I can post you should cuz I'm an idiot with posting pix, just so you know.

 

Yeah ill post some soon. Did you see the pictures of the sludge that i posted?
