 2001 Sprinter 313 CDI - Injector/s Leaking Compression
Hi all, I recently purchased 2001 Sprinter 313 CDI swb. It's started to make a choofing noise which sounds more like an exhaust leak. At first it would come and go but now it's much louder and there all the time & you can see fumes around the rocker cover. I've been told the injector/s are leaking compression causing it carbon up and now it's seeping from the side of the rocker cover. I could really use some help and guidance as this is a big job and concerned the injectors may be seized in. I could really use some help diagnosing wether I need to replace the injector/s or wether the seat/seal can be replaced alone providing they are a replacement part and obviously if that's whats causing the leak and not the injector itself. Thank you in advance. |
