Oil Pumps
Hi All,
Not sure this is the best place on here for this post but here it is, this has probably been covered elsewhere but I couldn't find it.
While stripping the front end for a cam belt change (and bodging tools together to do jobs I don't have one for) and after seeing so many comments regarding the oil pump/casing I checked the oil pump on my D3.
It seems to have the pre-requisite webbing to support the cam-belt tensioner, however I am curious about other later revision pumps.
I have on the front of my engine an oil pump with the number: 4R8Q-6600-AE stamped. Now I believe from other threads here that the last letter is the revision number and the latest is H ( 4R8Q-6600-AH )? I have been unable to find any categoric information as to what changed on the pump revisions, either my search terms are wrong or there doesn't appear to be a list of changes. Does anybody have any insight? Am I missing anything if I don't change it?

Hi
Don’t know about the numbers but have included pics of the old and new type ,
New one has a reinforcement
Hope that helps
Ps, if u fill in ur profile it will be easier for others to help in what model of disco u have
As long as it has the reinforced webbing on the pump it will be fine, the latest revision as far as I recall was for some sealant to be added to the allen nut blank on top of the pump.
Flack

Awesome, cheers guys. I shall look for an allan bolt/leak and add sealant if needed then.
Well, from what I can see it has the webbing, tensioner coming off shortly so will double check when I can see better.
For completeness, I believe one of the other revisions was a flange to prevent the seal being seated too deep.
Curious me would like to know more, but I suspect I shall never know.
