If that was mine and it has done any damage I'd be speaking to..... Citizens Advice, Trading Standards and a bloody good lawyer, I'm sure that if you supply a part which isn't up to the desired job the company should be liable for any costs incurred.... I'd fight it coz I'm a cunt like that....lol

lol, i never meant it that way, i meant it that there is now 'another' scare from the oil pumps.

there was one a while back about the cast ones,now the new ones are not right.

andrewg

ok sorry just seemed that way!

Dan

... and why not act a cunt like that Steve! We've every right to these days, whether it be faulty oil pumps or something else, the consumer gets fucked every time in this country now!

Glad you found it early Andrew but thats not the point, you should try for something more on this one!...

SteveB

Too right we get fucked left right and centre!!!!!!!

im sooo glad you guys are posting this up on here so COSWORTH can read it....you see guys i got absolutly nothing from them for my trouble....FOOK ALL. its wrong!

they have a name to live up to.... COSWORTH used to have a good rep, but today they certainly dont live up to the name.

i cant imagen this happenig 20 years ago, when real people were in charge.

Dan

Yup!

rapidcossie

I was just about to change my oil pump too...


Think ill stick with the one I have for the time being as it always showed good pressure and has no score marks in the drive etc.

glancy2081

whats happening to your car euan freshen up

PAUL V

Guess what turned up in the post today

Yes a New Cosworth oil pump What the F do i do with it

cossiedave

iTrader: (1)

i got told that pete mason cnc,s them and joe steven,s puts them together and cosworth sells them on from there dont know how true this is tho

Stavros

if it makes anyone feel better, i had a faulty "uprated" oil pump on my cossie give mentalist oil pressure, bursting the filter, and killing the engine while still cranking it over, right back in 2001.

so cossie oil pumps being shite isnt a new phenominon

fraser9764

iTrader: (3)

surely the sollution to this it to just weld up any new pumps like andrew has done before they are fitted to the car?

i know you shouldnt have to but it solves the problem....

rapidcossie

Engine is being checked over and few things changed/uprated

Alot of the parts on my build were never meant to run 550 bhp so we are adding proper oil squirts and a better head gasket/headbolt set up.

Chip

iTrader: (3)

Not really, as both the housing and the rotating bit both wear.
So only wat to repalce would be to machine it out to the next size up or whatever, which isnt something you can do at home.

andrewg

thats what i'll be doing from now on

watch this space--welded up cnc pumps for sale!!!

Chip

iTrader: (3)

The problem is though, if that bit has become dislodged because there is a significant force being applied to it by the pump (ie something not running true) then welding it up will stop that bit of the problem but will NOT correct the fault taht caused it, and will almost certainly mean a VERY short life for the pump!

andrewg

nothing to do with it not running true. its no where near a moving part.


its just small plate welded on the side then machined back so it looks one piece


the only force it gets is oil pressure

Chip

iTrader: (3)

I heard he was really pleased at getting on the official suppliers list for cosworth, and rumour had it that he was losing money on each pump sold just to do so.

He's going to be properly GUTTED if this does turn out to be anything but a one off

Chip

iTrader: (3)

Was just going by this bit mate:

If its off centre, then surely there will be a side loading?

Martin-Hadland

iTrader: (2)

How could he tell from the pictures we have seen that it's machined off centre??

andrewg

no its not that don't know why he has said that,

-beefy-

iTrader: (6)

umm anyone else smell shit ??

its not cow ?

its not horse ?

must be bullshit !!!!

the blokes talking out his fucking ass

whats the bet they know there a shit design ,

but as with most products , its cheaper to replace than completely recall a product ,

major brands been doing it for years !!!!

Chip

iTrader: (3)

He couldnt but he might know that already from inspecting others in the batch, oh no wait, hang on, this is a one off.......

Gatecrasher

Ohh FFS Totaly missed this post

Mike Should i be worried? what with bedfored saterday ect

As you know when i bent my Crank and harv put the engine back together in the box of bits i got back was my old oil pump

Also when the gearbox went the car wouldnt hold any presure in the pit lane we put this down to the oil being 10/40 and because i didnt change the oil as it was only just run in before the track day

since i have dumped the oil and it now has 10/60 whitch i was going to do Bedford with before changing it again for 10/50 as i assumed by then it will be proper run in and on its 3rd oil change so it should be ok to leave the oil for a while

im now shitting myself that im goinng to kill the car i know i have had a few good blasts in it since but nothing like the abuse it gets on track so i havent really put it to the test and the oil preasure only went shit when i started to get quicker pushing the car harder and harder

Im deff going to turn the boost down anyway now but where do i stand if the engine goes pop down to the oil pump

Ollie.

Didnt it blow up at daddy thrash?

MARCOSWORTH

iTrader: (24)

After months of waiting for these "good" oilpumps from Cosworth you get this,what a load of crap for such a company

Jim Green

Gatecrasher : Where do you stand if the engine goes POP.......On the infield, or next to your car.

Sad times when people put so much money into their engines only to find that a vital part could let go at anytime. It doesn't give an owner much confidence in his otherwise perfect engine build.

Don't know what to say guys.

Maxest : Your Ok.....Your engine was fitted with a genuine original equipment pump by Karl. No Worries There.

Sticky.

iTrader: (4)

Exactly what im doing, i was gonna put a new Cosworth oil pump in but im gonna stick with mine as it seems ok (just me being paranoid ) No disrespect to Matt thou as he only supplies them.....i'll stick with my pump.

Rod-Tarry

You are a real alarmist Chip .
I consider mine a high power engine & it aint dry sump. Done over 40k miles on engines over 500bhp & guess what no oil pump failures.
Dont think Mark has ever had a failure on dozens of high power engines.
If you want to discuss blocks failing im more likely to agree

Chip

iTrader: (3)

Mark hasnt built a lot of cosworth engines recently as far as im aware, so I fail to see what relevence that has to the problem of modern oil pumps, yours was built what, 5 years ago?

Ridgey

iTrader: (5)

A couple of questions:

Is this problem 2 or 4wd pumps ?

Is it mainly an issue for high pressure pumps ?

cheers

Martin-Hadland

iTrader: (2)

4x4 pump and maybe normal pressure as well as high.

Ridgey

iTrader: (5)

So replacement 2wd pumps are OK

Lambchop

iTrader: (1)

looks like it! thank fuck for that

Can I ask you why are you using a standard type wet sump system on a 700bhp plus engine?

Even the 300bhp WRC cars go dry sump for reliability.

Using a relatively standardish pump on an engine with over 3 times its original power seems a bit daft to me



Every race engine I've come across with big power always go to a dry sump system for reliability.

I know quite a few people who have suffered similar problems with diferent types of engines at around this power level. The main failure is it shattering the gears.


If the side of the pump hadn't of blown it would either have been the gears or oil filter next, this is not the fault of the pump its the fact its coping with 3 times the level it was designed for in the first place.

Because the engine is reving that quickly due to the large bhp increase it creates a spike in oil preasure with nowhere to go in the pump.

I suspect the relief valve was wide open too and couldn't cope with the huge flow of oil so instantly

Martin-Hadland

iTrader: (2)

Why not? It works on my car with no issues

AustenW

Not Yet but you never know

I wouldn't risk it if i were you Martin

My mate ran 800bhp for a years season and then had 2 pumps let go in the space of a few months. (Not YB might I add)

He's now going to a dry sump set up with remote oil pump

A grand well spent with Pace if i were you.

Martin-Hadland

iTrader: (2)

Thing is I have been running a standard pump for years without any issues but the only one time I have ever had oil pump problems was when I ran an external belt driven pump.

Maybe I will run a dry sump in the future but it will be another 'just in case' mod and will only be carried out when the engine has to come out.

What type of engine does your mate have that suffered failures?
