pre chamber gas leak

[rg2098]

Well let me start by saying I hate my engine, it shakes after Tomj balanced my new bosio nozzles and everything else I've done. Heres the problem... now the #5 injector has a large amount of smoke pouring from it. The only thing I could think of was a bad pre-chamber? What do I need to know about pre-chambers, removal, etc...?

(on the shake i've;
replaced injectors
valve adjustment last year
rack dampner bolt
new motor mounts
cam offset key)

number 6 injector? in an 83 om617? what

[pawoSD]

That could explain why its smoking if its the #6 injector on an OM617!

Just kidding.

Obviously its an OM617 with 5. I apologize for the typo. Now any actual advice?

By smoke, am thinking you mean external diesel fuel cooking at the injector indent on the cyl head. First thing I'd check is return lines, then the coupling where the tube meets the injector. I once cracked the pipe under the fitting where it meets the #1 injector on my 240D by NOT attaching all the pipe couplings, it cracked right above the flared end of the pipe probly through engine vibration. What makes you accuse the pre-comb chamber of leaking? If it was me I'd suspect installation of the injector.

I can feel air puffing in tune with the RPMs.
