My l84 5.3 cracked some pistons now thinking of doing a light hone but wanted to know if it would even save the engine ? The scratches are pretty light my nail doesn’t get stuck but I do feel em. The pours on the other hand I’m not sure what could have caused those little things ?
Okay so I broke my foot a last month so my truck has been sitting during the winter. Just recently the check engine light has came on.
I used my code reader and is said the thermostat was running cold.
And the engine fan automatically comes on and stays on for a little even after I turn the truck off.
My question is there a simple fix to this? Or would this require a replacement?
96 Chevy K3500 with the 5.7l It has about 215K miles. I am trying to diagnose a fuel pressure issue. My truck first started to run rough like it had a miss. Check engine light came on. I had codes for both banks being lean. I cleaned the MAF sensor with no change. I checked for vacuum leaks. I hooked up a scan tool and checked the LTFT for both banks. They are both at 25%. I hooked up a fuel pressure gauge to the rail test port. Key on engine off it is around 45. As soon as the pump shuts off it almost instantly drops to 0. I am trying to figure out if I have a bad check valve in my fuel pump or if my FPR is bad. Before this all started, I noticed a loss in power. It could barely get a trailer up the slightest incline. I was trying to see if I could find out the difference in the speed of fuel pressure dropping when the check valve in the pump is bad and when the FPR is bad, to try and isolate the issue.

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 !
Got my full console from Ebay used in like new condition. I did alot of research to figure out how to wire it so all the functions would work. I.e. wireless phone charger and usb/ cigarette liter ports for the rear passenger.
I have a currently have a 22 2.7l Custom that doesn't have the required connection under the front passenger seat. After hours of looking at schematics and testing wires, I managed to hard wire my center console to the fuse box on the passenger side.
Wire on the CC harness to Fuse box
Both Red/white to F5 (Battery positive)
Violet to F20 (Accessory on)
Violet/yellow to F23 (Accessory on)
BOTH Black to Ground below the Fuse box.
The only section I wasn't able to get working yet is the USB in the middle of the console (the one with the map SD card). This one I believe needs to be connected to the radio that has the built in navigation. (once I get one I'll update this post.
