Is it possible for exhaust to leak out the push rods? I think its on no.6. Replaced injectors with dpp performance plus. To front load Maintenance. Wouldnt start....so put the old ones back in (hopefully refund or new inj) starts but makes a ticking noise from turbo back to tail pipe. Heres what i found. And i downloaded the shop manual for the truck and followed it step by step.
