P38A Old member new issue

goreden · Jun 3, 2020

Hi all, not been around for a while but i’m back in a P reg P38 diesel and i’m pretty pleased with it
However i appear to have a leaking injector pump
It’s quite hard to see exactly where it’s leaking from but have read it’s quite common and can be done in situ
Was wondering if you helpful chaps would be so kind to point me in the direction of a repair guide and where to get new seals/gaskets form
Any help greatly appreciated
Many thanks

It's often the top cover seal that leaks, easy job apart from the special bolt head. This is the kit I used as recommended by Mark Piercy:-

If you need to go down to the next level, it needs marking up very carefully, I think there is a write up in the tech archive.

Thanks Datatek
Just looked at that on ebay but they won’t ship to the UK at the moment, i did find this earlier

Do you think it’s the same and is it worth buying the special sockets as well?
Many thanks

Sacrificial socket & hammer will take the security bolt off and replace with new normal bolt., can’t remember socket size - something tight

11mm socket rings a bell, hammered on.
I bet those irwin extractors would do the same job.

Same, use one of those 1/4" sockets that roll around the bottom of your toolbox, somewhere around 8mm. I'm too tight to replace the bolt so just leave the socket on there and reuse the bolt

You are selling them today son

RangeRoller dt · Jun 3, 2020

I’m gonna say 7mm?

Its raining so I'm not going outside to check

It’s in searchbar somewhere, he will find out when he compares odd sockets to the bolt which fits

goreden · Jun 3, 2020

Thanks for all the replies fellas, i’ll leave the special socket
I have searched the tech section for a guide on how to repair but can’t seem to find it (probably being a bit thick)
One other question i do have is that does the injector pump have to “timed” with the rest of the engine?

Yes, known as ‘static timing’

BTD’s guide is in here but it’s a zip file I can’t access

Best leave static timing alone unless you have the tools. Not required if you leave the pump in situ. Mark up the pump top on all sides as a tiny difference could result in no-go. If the pump has done 140k or over then the FIP is probably due a refurb anyway.
