hello gm-trucks commuinty i’m having issues with a smog readiness monitor not completing. any information on this issue would be greatly appreciated. my truck is a 2001 Chevy Silverado LS 1500 with a 5.3L v8 and it’s 4x2. all the readiness monitors complete except the secondary air system causing the truck to fail smog in california. i’ve heard the air pump turn on at cold starts and even replaced the passenger side check valve. also replaced the solenoid that sends vacuum. everything in the secondary air system seems to be operating properly but the monitor won’t complete. i’ve driven 100s of miles and done countless cold starts but no luck. even the smog referee said the system is working properly and i should just drive the truck more. anyone else experience this issue and what did you have to do to complete the monitor? there are no codes stored currently and the truck runs fine. thank you to anyone that helps
Good evening, I have 2020 Chevy Trailboss 1500 5.3 I recently ran into the issue of the water pump pulley breaking and wanted to see if anybody knows if it’s possible to just change out the pulley or would I have to change out the whole water pump?
I had just finished installing my cam and put everything back together but as soon as I go to turn on the truck it won’t turn on it just cranks and a lot of smoke starts coming out of the engine. At first i thought it was some oil that had spilled on the headers or on the block. But i don’t know what to do please help

I recently bought a (Gen 3) LQ4.
I'm trying to swap this into an (Gen 4) 07' Silverado which uses 58x Reluctor, 4x Cam Gear, Front Timing Cover/Crank Sensor, and 2 Knock Sensors located in the sides of the block.
I have a (Gen 4) Truck, So the timing cover/ crank sensor/ knock sensors can be used. I also have a (Gen 4) ECM/Harness.
I know I need to get 58x Reluctor Gear put on & get a 4x cam gear already
My questions are as follows:
1. Can I put a 4x Cam Gear on a (Gen 3 Cam) ? or do I need to get a (Gen 4 Cam) for the (Gen 4 Cam Gear) to work ?
2. Can I use the (Gen 4 Knock sensors) on the side of the (Gen 3 LQ4) ? Just drill/tap & mount them ?
3. If I keep the (Gen 4 Fuel Setup) could I just install that on the (Gen 3 LQ4) ?
Any help or advice will be appreciated.
I'll be documenting everything so others will have better knowledge when putting a Gen 3 Block into a Gen 4 Vehicle.
Thanks guys !

I just bought an LQ4/6.0 out of a 2006 Denali XL
Complete Long Block
Engine Harness /w ECU
The swap will be going into a 2007 Reg Cab Silverado.
Truck came factory with the 4.8L Vortec.
My questions go as follows.
1. Would the swap work easier since I have the ECU/ECM that came with it ?
2. 06' Below uses 24x Crank Sens... 07+ 58x Crank Sens... Could it work since i have the ECU/Harness ?
3. Would the truck still start up/drive without unlocking the ECU ?
4. What other things should i be worried about ?
5. What things should I get for the swap if needed ?
I will be using a JEGS adapter/4.8 Flexplate to mount the 4l60e to it "4l80 will be put in later"
