Hey everyone I've got a 2010 Silverado 1500 with the 6.2L L9H and 100k miles and it's got a pretty bad rod knock. I decided to do a oil change to check for copper shavings and to no surprise the oil as well as in the filter was filled with copper shavings. I'm gonna assume it's from a piston bearing destroying itself. At this point am I better off rebuilding the motor or swapping in a motor with similar miles like another 6.2 or a 6.0?

I'm hoping to spend no more than 3.5k but I wouldn't be surprised if it costs more than that

You could fix it for under a grand if the crank is not damaged. If you pulled the engine and opened it up, I'd remove all the pistons and rods and check over the crank. Send it to a machine shop to see what they say. If the crank can be cleaned up and ready to go again all you'd need is a full bearing kit and new gaskets to make it run again. But I'd also flush the engine out and put in a new oil pump as well.

 

A used engine around me is in the $1,000-2,000 range depending on miles.

 

Doing it yourself just requires a lot of time to clean things up and make it good again. Your labor is free and it's just parts you are buying. Aside from a possible machine shop needing to clean up the crank.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.

      I can't believe that could possibly be the case. It should be 36mo/100k miles from installation. Then again, it also seems like since a dealership installed it, it'd all be in the system and you wouldn't need to worry about registering, either. Shows you what I know. 😄 Hope this one outlives the warranty!

      I haven't seen inventory recovery from COVID.    In the few random times I 'build my own' truck or SUV, no one has the exact one I want.   GM has been working to lower incentives too for a long time.    A $500 incentive isn't getting me off the couch to go truck shopping.
