I could have sworn there was a dude in FL that does an injector cleaning service. Contact info would be awesome.
I think Greg posted he'd sold his half to his partner but it doesn't matter, still going. I've sent them injectors several times, always great service.
Mid 80’s is likely an L25, if so he’s fuk’d except used, or an old school diesel shop. That engine was built on a British Leyland long block. What’s it not doing that points to injectors? Will it run on ether?
I’m not 100% sure as I haven’t actually looked at it myself, but he says it feels like it’s running on three cylinders. It will run on normal diesel, just rough. He’s got a decent amount of mechanical aptitude so I didn’t question his findings, just tried to point him toward a guy we know.
With diesel it’s pretty simple, fuel, air and compression. He can crack the injector lines nuts loose at each injector to isolate the bad cylinder. Then pull the injector, reconnect it to the fuel pipe, crank the engine and see if it sprays fuel. If so, check valve adjustment and compression on that hole.
