Ok we'll after the new alternator drove truck a couple days bluish whitish smoke came back. Parked truck on incline overnight. Pulled egr valve today and very bottom of valve and bottom of manifold are gooey, ever so slightly. So I know cooler is no good but my question is will the mix of coolant and carbon cause this bluish color? I noticed lately that it is always worse at initial start and drive, as soon as motor is to temp for a bit it is usually small amount a smoke unless it idles in traffic for a bit the cloud is bigger. My assumption is as its hot it burns it before it has time to pool up till you get on it again. Also my deltas are always in check, usually 10 to 12 on long highway and never breaks 14 towing. So the oil cooler is partially clogged but is that enough to crack a cooler? I have cleaned valve and it never looked to coked up. Thanks josh
Lucky I already bought the egr gen two from ipr so no an oil cooler and some work!
