Smelly exhaust

[Coco620]

Hello guys !
My truck suddenly has smelly exhaust & a lil white blueish smoke... Doesn't run different just stinks makes eyes burn . Thanks in advance.

does it smell mostly like fuel?, oil? or coolant?

Are you loosing more coolant? ... Oil?

fuel mileage go down quite a bit?

When you open the oil filler tube cap, can you see a lot of extra smoke in there as well?

Just read an article where a Detroit guy had this problem and the dealership said everything was in compliance. Pittsburg Power put in some different pistons and a VG turbo on and it went to an average of 8.6mpg with no stink. Like Rawze says....what does it smell like?

Thanks guys , it's not loosing coolant or using oil at all ! The smell I would have to guess is fuel like, if I stand on the deck plate , I haven't pulled the oul cap off but will do tomorrow for sure! Thank you

By chance did you do the gear oil in the crankcase thing? That stuff stinks at first.

I did do the gear oil thing but I've been doing now since I joined this forum last year, this is new week or so ago thanks

A buddy of mine said it smells like one of his trucks did when he lost an injector, I did the injector cut out test all but #3 will stall the truck

A healthy engine will run on one cylinder at a time unless it is tight from a recent re-build.
