Inside of Bosch VE after a few 10k on bio

[Tony]

Had it apart expecting varnish and gumming blocking all sorts - after all, I don't water wash.  Pleasantly surprised to see it's all pretty shiny in there, including at the advance piston which is effectively a well at the bottom of the pump

[Dickjotec]

Very encouraging. Have you learned anything new about them?

[Twenty4Seven]

Did you find out what caused the runaway Tony?

[Jamesrl]

I took the hp pump of me hdi apart to find it as clean as the day it was made and I've never water washed.

I do get an accumulation of very liquid glyc in the bottom of the fuel filter though.

[K.H]

But if you water washed you wouldnt be able to take piccys you would be blinded by the shinyness of it!

[Head Womble]

Looks very clean in there Tony, a complete  contrast to the inside of the pump off SWMBO's old 406.

I'm starting to think its caused by the oil from my biggest supplier, manky old stuff it is.
The full return pipe on my Merc  blocked up recently , I still haven't had the time to get it fixed yet.

I was forced to wear a full face welding shield with a no.10 tint when I opened my pump and NO water washing, so there la la la ha ha ha.

That was just a reflection of the blinding light shining out of your rear, Mr RL

Couldn't have been, I have a cork fitted for the health and safety of others.

I don't want to dazzle people when I talk out of it do I.

I'd like to get the high-pressure bit off, but my screwdriver's can't shift the slotted bolts.  What is the best way to do this, invest in an impact screwdriver?

Edit: no worries, put a screwdriver bit in a 1/4" socket driver.  More photos to follow

A trick I learned when a boy was to use a screwdriver that has a shaft right through the handle (very common in my day) engage the blade, put a load on the screw and strike the shaft with a good sharp crack.

It may take a few whacks but usually works.

[Tony]

Sounds like it would.  Sadly I have no such screwdriver.

I understand that this is the modern equivalent:

Inside the pump there is some varnishing:



But!  This is only from where it has sat half-filled with fuel for the last few years - a definite tide-mark. The rest is clean

[Tony]

PS don't tell the missus this is what happens to the living room when she is away!

[Jamesrl]

Those impact drivers are good as long as you don't hit'm too hard like what I did and break the pin.

The tool I refered to earlier is known as  a Hammer through screwdriver.

[Head Womble]

I've got to ask, why are you stripping it down Tony ?
