Mate if the mechanic is coming down anyway leave it alone. All you can probably do right now is make it worse.

are you sure theres a gasket?,usually there's just precision shim/shims,btw from the pix it looks to have been leaking for some time,if you do remove the retainer be sure to replace with the exact same thickness shims and torque

No, I'm not sure there's a gasket. There's nothing specifically stated in the Workshop Manual, but there must be something there to keep the fuel in... and yes, I suspect it's been leaking for a while, filling the bilges with diesel at $1.30 a litre..

As I mentioned in the first post, I'm mechanically-illiterate. That's one reason I called the mechanic when it looked like there was more than just brute force required to fix this.

I was hoping that someone here may have come across this before. I have no idea how an injection pump works - and the Workshop Manual seems to indicate "if it needs fixing, remove the whole thing and return it to Volvo for repair.."!!!

an injection pump is precisely machined so much that a gasket isn't necessary,a gasket wouldn't be able to withstand the enormous pressure also it wouldn't be conducive to the critical clearance required,your right to repair this sooner than later because the leak will only get worse and eventually damage the the pump mating surface.

What you are saying makes sense - except that I don't see how shoving a shim between the "precisely machined mating surfaces" (as per the Manual) won't cause a leak!

The mechanc is supposed to be coming down to "have a look after lunch". These are the people who put the engine in, so they should (hopefuly) know what they're doing..

'kay.. that was a waste of time. The apprentice showed up and said his Dad is on holidays in Bali and won't get back till next week.

After scraping away some of the flaking paint it does seem that the leak is coming from underneath 2 of the 3 "faceplates" that hold the injector pipes onto the body of the pump - trouble is, you need a special 5-pointed wrench to undo them.

The workshop manual says "Send the pump to Bosch if the workshop does not have specially trained personnel with the necessary testing equipment".

But this engine wasn't made yesterday. It sounds like I'm totally stuffed this time..

Anyone got any other ideas??
