Diesel Smell

Lately I have been getting a faint burnt diesel smell coming from my truck, outside and inside. At first I thought it was exhaust from other trucks near by. It comes and goes.

I have look all over the engine compartment using a flash light: topside, underside both sides and do not see any signs or hints of a diesel leak anywhere. If there was even the slightiest leak one would be able to dust sticking to wherever there was diesel and there is none.

Anyone ever have this happen to them??? Can't find the source.

Truck has 60,000+ miles, stock, with 6 speed auto

check the EGR system for leaks, if it is a burnt smell. That would be the first place I would expect it to leak.

If it is a unburnt diesel smell check you fuel filter housing and filter. Also has the filter been replaced recently? If so the small drain hose on the bottom of the filter may have gotten diesel on the frame, block. but you did say you don't see any wet spots. If you still don't find anything I would check the CP3 IP as I know others have had warranty claims for leaky CP3s.

Good luck to you, as I hope its nothing serious.

Got the truck back today. It was a gasket leak on the EGR cooler. Covered by warrantee and they did my free oil change early since it was in the shop so I did not have to bring it back in 2 weeks.
