yesterday we discovered and oil leak-took it to the oil changer where the oil was recently changed. they say the leak is from a oil cooler- husband tightend it, now no leak there but we found another leak coming from a hose under passenger side that goes nowhere. oil pressure also low. what should we check for?:(

The hose on the passenger side is probably your crankcase breather (it is probably moist with oil). It really shouldn't leak from there unless you've got way too much oil in the engine. Check your oil level and smell whether there is any diesel fuel in your oil.

Thank you for your response- sorry for not giving you our truck details- It is a 2002 Duramax Diesel 2500 HD. We did check the oil and we believe it does smell quite a bit like diesel fuel. Can you tell me more about the injectors we might possibly be looking at and would this account for the low oil pressure also?

It sounds like you may have injector problems. You didn't mention whether your oil level was way past "full"; if that's the case and your oil smells like diesel fuel then it's time to go see a dealer and have your injectors checked out. Also a lot of fuel in the oil can cause the oil pressure to come down. For that reason and also because diesel is not a good replacement for engine oil don't drive the truck if indeed your oil has a lot of fuel in it. GM warranty on injectors in 2001-2003 Duramaxes is 7 yrs/200,000 miles so you should be ok unless you've got more than 200,000 miles on the truck.
Let us know how you go!

And being an '02 and if you have less than 200,000 miles, it should be covered under warranty.:)

We are in Susanville, California about 1 hr 20min north-east of Reno Nevada. The dealership that replaced our fuel injectors under warranty is Willits Motors in Susanville. They are under new ownership and are very helpful.

We hope this helps.
