Recently my truck had been exhibiting quite a bit of excessive blue smoke? Thinking and knowing that my injectors were worn, I went ahead and changed them all, my shutter and all performance and starting issues were taken care of with this swap and I love that. But I still have blue smoke, it is MUCH less, and mostly at idle and just getting into the throttle. What other things will cause the blue smoke, I dont have oil consumption to speak of, maybe a quart every 5000 miles, no oil is present in the tailpipe, like a blown turbo? And my turbo does not have any play in and out?
Just looking for more ideas on the smoke, thanks in advance.
I appreciate that and have looked over it in the past. I was thinking about the MAP or ICP sensors, but dont have any SES lights, or codes, what is the crankcase depression regulator valve? CCV?
Until I changed my injectors, it was enough smoke idling for me to be embarrassed? filling entire intersections, and slight haze in rearview while driving, chip has been in for alot longer than the smoke, I just started it up one day and it began smoking, after injectors the smoke is extremely less, but still has a little puff on acceleration and slight haze while driving if I look closely.
Just thought I would bring this back up in case anyone had any other suggestions, I will add that while it is smoking there does seem to be a slight lack of power, then as soon as it quits smoking I will feel the truck pull a little harder. Almost like a gasser loading up the carb? Just to make sure I pulled the valvecovers again today to double check connections on the injectors, everything was in good shape.
Update on my smoke, I guess I'm going to have to try to view some live data, My smoke is only when idling and up to about 1500 RPM. One thing I have noticed is that I now have a rough idle and will get a SES light, then when it smooths out the SES light goes out, mostly in these cooler mornings (13 F this morning) once up to temp shake(miss) is gone, but smoke is still present.
As to make an attempt at better describing my issues. I would describe my "rough" idle as more of a "lope". There are no noticable power losses about about 1500 rpm, but below that it feels like it is "loading up". Plan on viewing some data later this week, and would like suggestions on things to monitor? Whether or not they are smoke related may be a mute point, I could handle the smoke if it idled nicely. So I may have some unrelated issues. I will try searching around some more for some rough idle threads in the meantime.
Really? No one had any recommendations on things to look for with a slightly loping idle? I will of course observe ICP and IPR info, I was just looking for other things to check, MAP sure, thinking maybe EOT? My thought is that my truck is overfueling at idle? Make sense?
This happened to my truck. I did o-rings. Turned out to be a blown turbo seal and when I released throttle and the turbo spooled down it lost suction and a big plume of blue smoke shot out my stack(not the good kind). Ended up having to get a brand new turbo. Might wanna get someone to look at your turbo unless you know what you are doing.
good luck though I hate the feeling of not knowing whats wrong
