Oil leak - looking for hints

[John_W]

Ian,
These pictures show an O-ring which has done about 50,000 miles. You may just be able to make out that the outer circumference has become slightly flattened. This has happened with age and allows oil to leak past it.

The new ones you get should be nice and round in cross-section.

Sy, John,

Thanks for the advice, I have managed to order the seals from my local Advance Auto parts store, total cost $10.60, and they'll have them Saturday. The part is a different part number as it is not the Isuzu item but an alternate manufacturer, I'll compare with John's picture for size and scale, and if they match will post the details in the parts cross-ref.

And the plot thickens as I've discovered my vehicle registration (DVLA documents for those back home) and insurance documents which have to be in the vehicle over here, were stolen whilst it was at the garage. I won't be returning there for more work right away!!! The complaints have been delivered though.

Thanks again,
Ian

Mine leaked in exactly the same place as in your first pic i.e. under the cas. It turned out it was the rear cam blanking plug at fault.
Try this first prior to messing around with your cas as its easier.

P.s.

The 'O' ring i was sent seemed a poor fit so i added some gasket sealant also, and it hasnt leaked since.

Okay, in my father-in-law's words "It took an English half hour to fix."

In that we discovered on removal that we had the wrong o-ring, and had to trawl around for a parts store open on Sunday afternoons to find a better fitting, and more akin to the original, replacement.

That said, once we had the parts and the tools, the job itself is quick and easy, and the car ran afterwards, so a result I'll be checking for any fluid loss as the week progresses.

Ian's Project Tip: Surgical forceps like these http://www.krystalkut.com/50845000.jpg are the ideal tool for carefully grasping the bolt and washers and preventing their drop into the bowels of the engine. They are also handy tools for guiding everything back togther again.

Before anyone asks why I have forceps in my tool kit, my father-in-law used to drive an MGB in his youth, and has three sets of these forceps for engine tinkering purposes! That is his excuse, and he is sticking to it
