2019 Silverado trailboss 5.3l engine oil cooler line failure

TrailDemon have you check the level after they replace the oil line? You look like your 1/2 quart low on the stick now with that said if they replaced the line at the dealership then fill the motor with oil to the proper level on the stick and then started the motor the empty line and oil cooler will purge with oil (getting the air out) giving you about 1/2 quart down on the stick so fill it up to the proper level on the stick and keep an eye on it.

I did go over the oil leve days after and to me it looks like it’s missing more thn 1/2 quart 🤔

Not an oil leak, engine burning oil now because of the oil line failure and blew all the oil out. Read the thread. 

I think the last few years have shown these di gm engines consume oil, some more then others. Just look at the couple post were forum members took the head off their engines and found oil/carbon deposits all over the valves and top end of the engine. A reason why many here have chosen to install catch-canisters to help reduce the oil build up.

first service at dealer 6500 miles no signs of any oil leakage anywhere including cooler lines and crimps, at least that's what I was told!

In looking at the cooler design, it looks like you may be able to replace the whole setup with an AN fitting/braided line setup.  The attachment to the block looks to be similar to the LS designs, When I have a chance I need to look at the attachment to the radiator.  Of course if you do this and mess up its all on you.  Other option is to do a delete.  We'll have to see if its an issue like the window....bad supplier or if it a design flaw do to pressure changes.  I notice that my Oil Pressure varies quite a bit while driving and that could be stressing the connection.

Can you post a pick, if you havent already. going through all the pages

Hey, got my oil sample back from a 3rd party after this oil cooling line blew all the oil out of the engine  and it came back good no traces of any metal.👌  Good peice of mind to have after this incident. If this happened to you I’d recommend getting your oil tested too. Cheap to do for

Any updates on this? What build dates were affected? Does the green line mean the hoses are a new design? Etc.

 

Thank you

I wish the dealer cleaned the oil well before handing me the car. Very disappointed
