Hi all,
I've got a strangely intermittent diesel leak on a Jeep Grand Cherokee 2.7 CRD (believe it's the same engine as an ML270 CDI). Essentially engine had Black Death which I fixed and engine was running sweet with no leaks or smells. Drove it around for a week until Saturday morning when it decided to gush diesel out like it was going out of fashion - 5-6 simultaneous almost constant drops coming from the high pressure fuel pump (Bosch unit with 748 CN7 stamped on the casing). Left it overnight and started it this morning and there appears to be little to no diesel leaking?? How can this be? Does the HP pump need the seals replacing or is there another common issue that could cause this? Any help always greatly appreciated!
