Power Loss/Oil Leak
Hey guys, newbie here, hoping to get some direction/advice. My truck is a 2003 6.0 F-350, bought two years ago now with 102,000. For several months I've been getting an on/off whiff of coolant. Took it to Ford for pressure testing three months ago and they said it checked out, no leaks.
Saturday I was hauling my race car back from Thompson, OH. The antifreeze smell became consistent, turning to an even uglier smell and a serious loss of power. Boost guage was cycling back and forth and sounded like the turbo was hitting an air release valve (waste gate?). Black smoke puffing on acceleration. Limped it home and discovered oil leaking on the tranny housing and driveshaft near the coupler.
The coolant appears a bit dark (not sure of original color), but not overly oily. From what I can tell off that dinky dipstick tip there doesn't seem to be coolant in the oil, not milky looking.
No overheating, but coolant level was slightly below MIN and hadn't checked it since Ford looked at it.
Anyone have any ideas? Help! I wrench on gas, but lost on these smokers. EGR valve/sensor maybe?
