Hi,

Been out in my type r today and when I gave it a little blast at the end of the rev range the oil pressure light flashes and the engine kind of shudders.

The first thing I checked was the oil (obviously lol) and thats fine, may have a little too much if anything but that was with the engine hot.

Anyone have any ideas

The oil light only measures oil pressure i think you could have a problem with your oil pump i wouldnt drive it till you get it looked at mate

Cheers mate, any idea how to diagnose a faulty oil pump? Its running an apexi ecu with hand commander so have a lot of sensors everywhere. Dont know what most of them do tho lol. Will any of them be ablr to tell me?

Keithys

I dont to be honest mate i know if it flashes on at idle on a highish mileage engine its not much of a deal but at high revs its more of a worry sorry i cant be more help mate i would deffo get it checked out before you used it though

Ask a garage to check the oil pressure?

TBH, the OE switch comes on at about 14psi, which is when the engine is fekked anyway.

I'd be particularly worried now......

Oh god.... I have been reading up and the symptoms (shuddering a bit under hard acceleration) sound a lot like fuel surge. Also when it did it my fuel was almost down on reserve. Could it just be that? (He says hopefully lol)?

Yes, but why would the OIL light come on?

You sure it wasn't the CEL?

Get the oil pressure checked for peace of mind and fit an oil pressure gauge to keep an eye on things.

im pretty sure it said oil pressure, I only saw it for a split second and after that I left it alone.

However I have also been out today as I had to take it to the body shop for a quote on the rusty arches and put a load of pet back in so decided to hold my breath and test if it did it again on the way back and it didn't? came on boost nice and held it all the way to the top of 6k??

im going to get an oil gauge to keep it anyway and its going to thwaites development in a couple of weeks to have a check over and discus different turbos and a simtek so ill get them to have a look at it as well.

im hoping its one of the classic Scooby "hissy fits" I have heard about lol so I can spend the money more boost lol

also when I was out in it yesterday and it did the shudder thing it was when it was hammering it down for about half an hr, could it be anything to do with water getting in somewhere??

do you know what oil is in it at the mo?
could be that with hard driving its thinned out (ie got very hot) and is not making pressure.

optimum oil temp is around 120 degrees, above 140 and the oil starts to break down.

apparently its Millers 10/50 NT, I cant confirm as its not had a service yet in my position, the oil is very clean though so don't think its very old

hmm, oil should be ok then as thats good stuff.
could be a faulty oil pressure switch, pump etc.

Haha. Just more impatient lol

More like 90/95Deg C on a scoob, you should only see 120 degrees on track or continuous hard road use IMO

Fudgey

Depends on oil a lot too, but optimum running temp is higher than that.
makes me laugh when you see people with oil coolers fitted to road cars that just arnt needed and could actually damage the engine they are trying to protect.

ideally above 100 degrees is good as it boils off water vapour etc

update on this, the oil pressure is fine, it did it again today and i caught a look at the light that was falshing and it is the check engine light. does this mean its fuel surge/cut?? if so how do i fix it?

ill start a new thread with a better title

Are there any codes stored?
Do a search on how to read the codes, read whatever is stored and come back to us.

just tried it but its not doing anything at all, its running an apexi power fc ecu so will it still work on the black connectors?

JTinnovations

iTrader: (2)

Nope

BigZee87

iTrader: (3)

That's helpful :/

so how do I read the fault codes off it??

You either re-fit the original ECU, or I think you can use some kind of Apexi device to look at sensor values to see what's up. I didn't elucidate as Apexi is not something I know much about (other than that the OEM-style code readers won't work, just as they won't for Syvecs, AlcaTek, MoTeC, GEMs etc etc).
