For most of us residing in the Midwest and Northeast, this winter has been pretty brutal so far...

 And as of today, there is no end in sight for the frigid temperatures we've been experiencing lately.

 As you can imagine, sub-zero temperatures are hard on our engines. Ice-cold oil might leave you with low oil pressure for a period after startup and gelled or frozen fuel is a possibility even if your truck only sits for a few hours. Then, there's arguably the most violent part of an engine's operation: start up. In one Diesel Power reader's case, a 0-degree cold start with a generous shot of ether mixed in yielded a bent pushrod (pictured) for his 12-valve Cummins. Early diagnosis is that the camshaft broke, but we won't know all the details until he digs a little deeper into the high-mile engine.
