Big End engine problem Brisbane - WORN OUT

Worn out big end bearings is a normal condition after a reasonable amount of kilometres. (say 180,000KM upwards) However premature wear can occur if conditions are less than satisfactory. Failure of oil pumps, oil pump drives, blocked oil pick ups, dry starts after oil filter changes, low oil levels are all conditions that can result in prematurely worn big end bearings.   Early failure after an engine recondition or rebuild can be the result of an initial dry start, incorrect bearing nip or insufficient bearing clearance. In modern engines most of the premature bearing failures are the result of low oil pressure caused from a blocked pickup. The blocked pickup is usually the legacy of insufficient oil and filter changes. As manufacturers extend the oil change intervals to try and lower the servicing costs to compete with the promotion of lower maintenance costs they are causing many engines to prematurely fail around 100,000km to 125,000km. Oil and filter change interval of 5000km is the best and cheapest protection for engines Disclaimer Agreement : Every care has been taken in writing this information and procedures, but no responsibility can be excepted for errors, omissions or misuse of this information and procedures.
