You know how you can set the idle and timing really good and quick on an old v8 like you did to Keith’s duster at Carlisle last year?
well that’s me with the cummins ISB series. I’ve played with them so much as I was growing up, I can detect the slightest pitch change and usually tell you what’s wrong before it majorly goes wrong.
That said, as loud as the ***** is, the screw driver trick seems to work much better on it than on quieter engines. Not sure why.
anyway, with the ticking coming from the intake manifold, which is where the injectors go in, my guess is the diaphragms inside to nozzle have cracked on at least one injector, meaning the tip is smacking the nozzle. I’ll pull them and send them out to be check for 10 bucks each.
