Chevy 5.3 Burning Oil, smoking, how to fix.

[@211milkman]

Just did this on 2011 Silverado. No more smoking on start up. Thanks for sharing this informative video.

[@stevewollschlager469]

This was misdiagnosed by several dealers, or they just wanted to over charge me for some other issue. My 2010 Silverado smoked like yours with a very rough start up. Could not get the check engine light to turn off for over a year. which also means you can not use auto start. I did use the Dorman though, not knowing any details about that part vs GM. Long story short I fired it up after installing and low and behold my check engine light turned off immediately and has not come back on for about 500 miles. Knock on wood. No more smoke on start up. Thanks for the video.

[@chrisheffernan6600]

Did you have problems with the Dorman part? All the reviews I've seen people rave about the Dorman valve cover.

[@Wollsch1970]

@chrisheffernan6600 No problems at all. Changed drivers side only. Took a maybe 30 min.

[@abdben1101]

Hey ! Did your truck smoke on the high way too on high RPMs and when you go up hill ?? Or only at startup ?

[@troyseaman1045]

You can also use the old valve cover, you just need to drill about 5 holes in the baffle on the inside for more drainage, it works well!

[@troyseaman1045]

Always check the rubber connectors at both ends of the hose from the back of the valve cover and the intake side , mine were split creating a vacuum leak

[@amandazimmerman5128]

Any chance you have a picture for reference?

[@alexlora6058]

Awesome video! Thank you for showing before and after results. Also for showing the difference between the old and new cover.

[@SamAceRothstein]

You should wipe down the surface of the heads where the valve cover gasket sits using a rag damp with brake cleaner before reinstalling. I had the blue smoke too, but I instead drilled some extra holes in the original valve cover and enlarged the original weep hole which seemed to fix the problem. I haven't had a chance to check the oil consumption yet, but the blue smoke is gone

[@2Jeezuzisreal]

We decided to drill out our old valve cover as suggested by several KZbin tutorials for the LS engines. We have a Yukon 2005 5.3 and we did this drilling out at least 10 holes and it all went well we test drove it the first day for 10 milrs and shut it off. the next day unfortunately it started leaking down on the exhaust manifold and smoking. I assumed the original OEM gasket would be sufficient

[@tristatetrifecta]

I had the exact same issue... valve cover replacement fixed my issue also.. great video!

[@jesusreal2658]

I have a 02 suburban 5.3, I removed the catalyst and it started to burn oil, I changed the pcv valve but after driving it still blows between white or bluewish, if its stays parked and turned on is does thorw as well and even after accelerating it seems that it accumulates the oil and it throws a big cloud of smoke then it disappears while driving, any experience with this?

[@jayzon31]

Valve seals are worth changing as well brother, just did mine yesterday, lots of oil leaking... something to think about.

[@georgelugenalt200]

Great job bro. Now get that underbody rust dealt with. Even bare primer is better than rust!!

[@c956rubber]

I have a 1992 gmc sierra 1500 that I bought for a project, had this issue of blue smoke on every startup...well I changed the valve stem seals and no more blue smoke

[@RustBucketRepair]

Your 92 will have a totally different pcv system.

[@c956rubber]

@@RustBucketRepair I also changed the pcv valve with a brand new pcv valve and tubing, unbeknownst to me when I bought it, I found out that the black tubing that goes connected to the pcv valve and carburetor had a hole in it...just glad the blue smoke is gone and wasn't a more serious issue like the piston rings.

[@DougHinVA]

PCV valves are cheap to buy for a 2000 Toyota Corolla and easy to install (new) and the hose is fairly cheap.

[@RustBucketRepair]

Not on this model. The pcv valve is built into the valve cover. You have to replace the whole valve cover. I was surprised too. Not like the old days.

[@brianlivingston7303]

You have to do an additional update to the new valve cover...You have to drill 5 I believe are 5/16 drill bit, the exact location for the procedure is online...5 additional holes...

[@GhettoWagon]

Did yours also smoke alot at Wide open throttle? Have an 06 5.3 doing this now, besides the smoke it runs fine. I know it used to drink a little oil but it leaks out so much from about every seal and gasket now its hard to tell how much more oil its consuming. 176,000 mile Poj it is. Ruined

[@RustBucketRepair]

Smoked the most at startup, but did also smoke at w.o.t.

[@GhettoWagon]

@@RustBucketRepair YA i have no smoke at startup I thought I had the updated cover on the 06 but that was the 2nd update. Then they went to a 3rd update which is the "427" cover Arrgh!

[@Kevin_Yagoonie]

I really need help because this got me scratching my head. 05 5.3 270k. Every once in awhile I'd get a bit of smoke on startup nothing major. Well couple weeks ago I was out running errands. Truck drove great like always. Got home and parked it for a few hours. Had to go to corner store and while backing out my driveway I had no brakes (brake line from master cylinder blew under driver's side door) so pulled back in and also noticed idle was a little off and bouncing like it wanted to stall. Truck sat for 4 days until I could replace the brake line. Well I started it and now it smokes out the tailpipe and has a jumpy idle. No check engine light or overheating and oil looks good with good pressure. I know about the pcv valve problem these have but I don't think a pcv would cause this much smoke. I'm scared to drive it. Weird this happened when my brake line gave out. Help would be greatly appreciated

[@RustBucketRepair]

First off, I'm not a mechanic, so take what I say with a grain of salt. If it's the pcv valve, the smoke should clear up after the truck runs for a few minutes. The bouncing idle could be a fouled plug from the burning oil. My #1 plug would foul, but I'd also get a check engine light. Run the truck for a while and see if the smoke clears. Also, pull off the hose from the pcv and see if there is any oil in it. It will be very little. Wipe it with a paper towel and see if there is any oil on it. The only way the brakes are connected to the motor is through the vacuum line. Could that be part of your problem?? I don't think so.

[@jimmydavis6254]

I know this is a couple of months old, but I bet your master cylinder is leaking brake fluid into your brake booster and the vacuum is pulling it into the intake manifold and burning it along with the gas causing the white smoke.

[@Kevin_Yagoonie]

@@jimmydavis6254 yeah that's what it was

[@mrmoparrr]

Seemed like moisture which is Byproduct of combustion, nice fix !

[@roltyd22]

Is this applicable on a 2003 Tahoe 5.3 or no? Its got just the hollow shell pcv valve

[@RustBucketRepair]

From the little research I did it looks like your truck takes the same valve cover as mine, so I'd say yes.

[@christiancervantes1769]

Before you did the Valve cover change, Did your cabin smell like burnt oil when you shutoff the vehicle?

[@RustBucketRepair]

No it did not.

[@billydenham9313]

I've got a 2012 Chevy Silverado 1500 5.3L and when I pull out at a red light or stop sign sometimes, I see a cloud of smoke behind me. I've replaced the valve covers on both sides, but I'm still seeing the cloud of smoke. The cloud of smoke doesn't show up every time I pull out, but I'd still like to know what the problem is so I can fix it before something bad happens. I just bought this truck last year for $18K so I'm pretty much stuck with it for a while. Any ideas on what could be causing this? Reply

[@ryanwebster2470]

[@ginoa1663]

My 2008 avalanche ltz smokes a white cloud when I use the remote start and when I check the spark plugs on cylinder one there was oil on the spark plug. Do you know if this fix the problem with oil on the spark plug? Great video on the process of changing the cover. Thanks

[@RustBucketRepair]

Yes. My #1 spark plug got so oil soaked I"d get a misfire and I"d have to replace the plug.

[@RustBucketRepair]

Well over a year and and still no smoke!

[@andycue38956]

I got a similarity with white smoke but not on start up, only when in Park and running for awhile then as some as I place into drive position then a huge cloud of smoke comes out once I step on the gas then after awhile it goes away but as I place it back in Park and just let run it starts to smoke again

[@RustBucketRepair]

@@andycue38956 Pull off the PCV line. If there is any sign of oil in the line I'd replace the valve cover.
