I recently had my Ford 201 cid 3 cylinder Diesel engine from my 1971 Ford 4500 TLB completely rebuilt. I installed it and have it up and running and it currently has about 4 hours on the engine. I have been running it without a muffler and have noticed I am getting a bunch of small oily soot spots / freckles on the tractor hood and surrounding area.
I know diesels can be “dirty”, but is this to be expected even from a newly rebuilt engine? It may have been happening before the rebuild, but I never noticed it with the muffler on and blue smoke.
It does have new aftermarket injectors and the original untouched injector pump set at the proper timing. It starts right up even after sitting for weeks and appears to burn pretty clean without any noticeable smoke above 900 rpms. When idling below 800 rpms you do start to notice some gray smoke and roughness.
Should I be concerned with the soot or rough idle below 800 rpms?
Thanks
