Maybe check the fuel tank vent on the fuel pump? Could be pressurized once it heats up. Or a different cap if it's not OEM.
I'd check some of those crispy wires for kinks or fraying. Might even consider tearing off the old electrical tape to check and then replace with new tape or aluminum...
Sorry, got lost in a train of thought because I was worried about rod bearings. I'll post a video when I have time.
With no CEL, I'm worried I can't trust the instrumentation. Aside from HG, no real maintenance history.
Valid points that I absolutely agree with, I bought it as a project and I...
Lots of helpful ideas guys, thank you.
Yup, first thing I checked. Light turns on then goes away when started. No codes at all except for the airbag light. No CEL with O2 pulled, engine dies without MAF, no CEL if I pinch the EGR hose and kill the engine. Can't think of anything else that would...
Its a 97 OBDII, just curious how that makes a difference? I haven't replaced any PS components yet but it doesn't sound like it's coming from the front. It sounds like it's near the top and towards the back of the engine near the intake pipe.
I have not... that's a good idea though. I'm...
It increases with RPM. I'm not ruling out an exhaust leak from the manifold, I added all new gaskets but it's an aftermarket exhaust and some manhandling was needed. It's one of the reasons I tried disconnecting the O2 sensors just to see if it made a difference. I'm really confused why it...
Yea, I read through some of those posts. I've got a stethoscope on the way to try to figure it out.
Yup, that's my move once I get the truck back together. I've never met him but I have heard of him.
I just figured I'd throw up a post since the CEL issue is non searchable. All of the posts...
I bought the truck from a mechanic back in April and it was pretty much straight piped so I never heard a knock if it was present. I haven't driven it since I bought it because I wanted to baseline it.
I've replaced full exhaust with cats and Denso O2 sensors, spark plugs, wires, valve cover...
Thanks man! That was a very detailed answer and I will bookmark it for future reference. It's definitely a labor of love and I will likely do a hundred hours of research before I even start. New armor is looking fantastic!
I bought an 80 that was beat on, it came with spare birfs/shafts that lived outside for a while and I got some birfs/shafts from an 80 that was totalled due to vandalism but really clean otherwise.
I haven't taken out my birfs to reseal everything yet but I wanted to know if there were any...
