WARNING new cosworth oil pumps!!

Tim,
I'm saying it as I see it
. Something machined from a billet is always going to have better tolerances than a cast item. So from this point of view the new one IS better made and gives better oil pressure consistancy than the OE item, I agree that this is of little use if there is a structural design issue. I also agree that this needs urgent clarification / rectification / confirmation that it is a one off.
This is the first failure I am aware of of a new billet pump, so it needs to be high-lighted to Cosworth (which I have now done). Previous failures of pumps have been the cheap copy cast ones, which people soon started to avoid in the promise of a better one from Cosworth. If this "better" one is failing as well, then it needs looking at ASAP....

I recently sent the first one of this batch back to Matt as it had jammed when timing up my new engine build so had to strip it down again! Matt replaced it with a new one stright away which is in the car now so hope it will be ok!
Its not Matts fault this pump the same as mine is direct from cosworth themselves Matt is just a supplier of there product they have replaced the cast steal original items with this supposedley stronger billet aluminium item i would say it remains to be seen!

i had this argument with jeremy scott two years ago, they made a batch of faulty oil pumps, because a certain person who makes the pumps for cosworth cant measure for shit.
they made the internal components to big, and the pump made way too much pressure, burst an oil filter at idle, and fudged alot of my engine.
i complained like hell to cosworth, who just didnt give a shit, there atitude was "heres a new pump, tough shit about the damage"
tbh they arnt even worth talking too, there pumps are complete shit, and there attiude and customer service is even worse.
and jeremy scott, is a waste of time. he even had the nerve to slag off the supplier of the pump to me via email ......so i showned the supplier what he said..ha ha!
anyway , they just dont seem to understand...giving me a new pump did not solve my problem, someone has to take the time and cost of the repair into consderation aswell....and it should be up to the manufactures of the problem parts imo....

From Cosworth Racing:
Hello Mike,
I have read the posts and have also spoken to Matt Lewis. I will be in contact with the supplier this afternoon and get him to have a look at the images on the forum.
It looks to me like the central rotor bore has been machined off centre and caused a structural weakness. We will work with the supplier to rectify the possible issue. I will let you know our findings.
I suspect this may well be a one off as we have not had any issues or failures with the new design of oil pump. However, we take this issue very seriously and we will do all we can to resolve the situation.

The engine did 1500+ miles with it fitted including being run in and it was holding perfect 3.5 bar oil preassure once warm
I bought the pump off Tim Finch as he had a batch load he got from M-Sport At the time

As Martin says how can it be a one off if they are cnc billet they will get made in batches all identical.

no it was on another engine
they have bored in throu the side of the pump to do machining inside it then pressed in a blank into the side of it to blank the hole and machined round the out side so from outside it looks like one piece

Hmm, good oil pumps, like 200 blocks - worth more 2nd hand it seems! (handy that, as I have most of my old engine to strip and sell shortly!)

The engine andrew is talking about is a very trick spec engine thts in a mk2 escort 570 bhp , nikasil linered block ect so the cost of this could have been massive i agree they should at least send him new shells mains ect that he replaced , considering the engine hasnt done any sort of mileage
