I had the same problem a month ago with my 05. I change my oil religiously and when i pulled the valve cover it wasn't gummed up at all! I bought a new valve cover. Didnt wanna risk any of the junk from the internal pcv dropping down. Haven't lost a drop of oil since and no more smoke. Changed the oil immediately after and will be changing it again when I hit 1500 miles to make sure everything is clean. If none of that works you may need new valve seals. Good luck!!

It is either oil seeping past the rings, or Mentelo trying to mind meld with you.

Its come back off and on. Hasn’t done it in a while. One thing I noticed in winter when cold out. It will smoke a lot. Other vehicles i see on road are not smoking that much. What could it be? 162k on it now. Have had truck since 70k and only used full synthetic mobile one oil. I let truck warm up in winter months before leaving.

Smoke or just lots of steam from the exhaust?

 

I always see larger vehicles with bigger engines, more exhaust pipe to heat up show more steam from the exhaust when it's cold outside.

 

 

Blue smoke at start up is likely the valve seals or the PCV system is filling the intake with lots of oil. Switch oil brands if you have too, see if anything changes. Amsoil sells their OE brand for like $5.80 a quart or something, it's often cheaper than Mobil 1. Atleast at the Napa I shop at.

      OCI, not when but why?

      By Chuck FB · Posted

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.

      Looks nice. I still have my 2000, 1500. Bought a 2025, 1500 for retirement. Feels solid. These trucks have a bad rap on the internet. My brother has a `24 1500, 5.3 with 52,000 miles. No problems at all. Mine hasn`t either but mine`s only at 12,700 miles. Have seen some of these things with 100,000 miles with no problems.
