Don't go for 'micky mouse' named stuff! I'll give you an example about my car. I bought it 2nd hand with a an oil filter in the boot. Sometime after fitting it, the engine developed 'big end knock' for 5 secs on starting. I had the bottum end stripped down and found nothing wrong. I crossed my fingers and drove the car for a further year without mishap. On the next oil change I bought a manufacturers oil filter, from that moment on the engine never missed a beat! I decided to cut open the old filter, to find it was not fitted with a 'one way valve!' This was an expensive lesson I have not repeated again! Most cars, and I suppose boat engines are not alot different only need a filter change once a year. Modern diesel engines are very susceptable to having to problems with 'cheap filters' allowing dirt to scour the HP parts........ Please don't cut corners on a few pounds. 'Sail or drive with peace of mind.'
Unlikely to be a manufaturing fault, more likely the wrong filter for that version of the engine. If you go to a filter specialist they usually know the right item.
Sorry, I did not want to imply it was a manufacturing fault! I wanted to point out that certain manufacturers STILL specify items are suitable for XXX engines. When infact the materials are sub standard. ie corners cut, or removed! Ever put the very, very cheap brake pads on your car and driven down from the Lake District?
Bearings, seals, filters etc. etc ................ buying the "Named" item can be an expensive route .... but buying as per Type # can be rewarding in saving precious dosh. Being correct in specifying Type # and application - the item you buy .... we assume you are in civilized Trading Standards governed location ..... is to be fit for purpose. If it is not - then supplier and maker of the article is liable for your damage etc.
Why pay through the nose - if Unipart, Les Smiths, Halfords or Lucas / CAV etc. can supply same spec item ?????
Ok - I know .... there are some who have comfort knowing they have bought "correct" item .....
In the south I use Camberly Auto Factors, I expect there is a similar firm operating in the North. CAF are very obliging in matching up marine engine filters with the automotive ones.
My 4-107 ... same engine basically as the 4-99, 4-108 as well ... survives on the cheapest Diesel spec'd oil I can get .... usually via the local Auto Acc's shop.
I certainly wouldn't waste money on high priced oil !!!! The average Marine Diesel in a yacht doesn't work enough to get so cosseted !! The biggest worry is not engine wear due to use - its due to non-use ! That is acids, water etc. that accumulates in sump and destroys the oil.
But what do I know ...... hey Meow !!! Woof Bloo** Woof !!
