Hazing on idle, is my timing advanced or retarded
Hey guys, new to the cummins side of this forum. I have a 12 valve cummin in my Chevy. Just did a bit of work to it and now it hazes a fair bit of greyish white smoke on first start of the day after sitting all night. It did it before but not as much. I always figured the truck had a fair amount of timing advance as I read somewhere that close to 20 degrees will cause this. Since I put 90 horse injectors and hybrid delivery valves. Now it hazes quite a bit, cleans up after about 5-10 of idling and after sitting all day after driving to work it doesn't haze at all. Just a small puff of black smoke. So I'm wondering if this is timing advance or timing retard I'm dealing with. Don't wanna pay someone 300$ just to find out I have around 20 degrees because I'm ok with that. Any insight would be greatly appreciated!

Sounds fairly normal to me ... might toss a Tork-Tek OFV adjustable in the return side to boost the Fuel pressure .. Helped mine quite a bit ..
