Well I’ve spent 1 day on this vehicle. I’m fishing for the most information I can get. I understand I have further diagnosing to do. I’m wanting to see if anyone has seen wiring issues or ECM problems. I purchased this for $2200 and it’s super clean. So putting the money in it and doing the job...
Close to same spot as oil leak....drivers side close to the front side of engine....I bought an OE thermostat I plan on putting in also due to the code....
Compression test is a good next step....
Checking the wiring loom for cylinder 4 ignition coil and diagnosing the MAF are also on my top...
I’ll keep this thread informed as I tear into it. I’ve seen that other “thread” and hope I don’t get that far and if I do I hope I don’t have compromised threads or worse yet a broken bolt....which I seen some dude extract on a tube video
It has a coolant drip visible on the ground...but not the couple of fl oz missing from the reservoir. The cooling system was pressurized for 30 min. The oil leak was a constant drip ending mostly on top of the front differential driveshaft joint. Not sure if the smell wasn’t the unburned fuel.
I think I’m going to at least tear down enough to locate the oil leak and replace the injectors and fully inspect the cooling system components. Probably change the plugs. I’m not 100% convinced it’s the head gasket. Probably still do full timing job.
Just purchased a 2010 5.0 LR4
Codes:
P0300 random misfires
P0302 misfire cylinder2
P0304 misfire cylinder4
P0316 multiple misfires detected (1000rev)
P0354 coil circuit
P0100 MAF circuit
P0128 coolant thermostat
Plus a major oil leak.
My findings: swapping plugs and coil packs with the other...
