Another Warning: Run away Diesels

[cully]

be warned over filling the oil on a hdi will cause it to run away too
had this experience going up haldon hill nr Exeter on full boost then it took off filled the whole hill with thick black smoke behind .
throttle peddle did nothing. it eventually eased off towards the top of the hill, cars been running fine ever since

think i was lucky the engine was under load or it would be toast
