tvr 2.9 s oil pressure

[bagof]

hi there ive just bought a tvr s 2.9 111000miles runs great no knocking (TRYED pulling of in 3rd)BUT oil pressure is 0ish (5psi at best) at tick over rising to 25psi at 2000rpm and 40-50psi at 3000 plus pulls like a train to 120mph no knocking in high gear at low revs so!!!! q is should i be worryed or not??

Hi Rob and welcome to the S forum, sounds like it could be the oil pressure sender unit, i had a similar prob. with mine before it gave up the ghost and dropped off to zero. I repaired mine for the hell of it but only after fitting a replacement - one of these off ebay
http://cgi.ebay.co.uk/OIL-PRESSURE-Sensor-Sender-f...

Did the job with return to good oil pressure on turn of key, for £14.90 delivered - not worth buggering about with the old one.

Welcome Rob, where in the Midlands are you, there are a few of us, some even have a car thats in one piece!

More the merrier welcome aboard Rob.Based in Leicester myself.As for the oil pressure I believe the gauge should read between 50-70psi.As Ian says it sounds like like the sender unit.If it isn't someone on here will have the answer I'm sure.Have you got a picture of of your S .

Hi

The oil pressure gauge on my S has never worked and I've tried various places for a replacement, all of which failed to find one. And then you go and post a link to what seems perfect!

Is the part in the link a like for like replacement?

Not much to report really - I've been doing some engine fiddling Link Here but since I got made redundant earlier this year I'm being cautious with the cash, and to be honest this working for a living lark takes a lot of time up!

I've just finished one contract and have now started some other work which should take me at least till the end of Jan, possibly beyond, so fingers crossed.

Good luck with the upcoming work

Its not a like for like but works well. There are like for like replacements available from TVR car parts etc but i also heard that there is more than one type of these and may not work on your car and for a price approaching £50. This one has two terminals as opposed to the original single terminal but you just run the original wire to one post and from the other terminal post make up a wire to earth on the engine somewhere. The seller is good to deal with and i got it next day.

Latest work is actually getting my hands dirty, up and down ladders installing security equipment, cabling etc.
Hard work but if I'm honest I'm enjoying it far more than flying a desk, and there's potentially over 600 sites to do!

By chance I met a guy who has been running a fairly small innovative security company for some time, but has just secured a couple of big contracts as he has a really clever product set, chance conversation and all that.
Now I'm renting a van and have half a dozen sub contract guys, its all a bit of a growing snowball at the moment

Edited to add - sorry op I hijacked your thread, back to 2.9 oil pressure....

That is the oil pressure sender I posted on a thread a while back and several people have used it successfully since. There are some notes on my site at http://deadpineapple.net/tvr/diary/2009.php under the May 23rd entry. The zero psi resistance of the new sender was 264 ohms and which worked beautifully with my gauge.

It is worth a punt and if you find it doesn't work then I'd take it off you as a spare fr my ever expanding pile of bits.

Excellent thanks - worth a go.

[S2 Giles]

As long as it moves when you build the revs then its fine. Only worry when it never moves off zero..... then just wait for the bang

[Jed-S]

Only other thing I would add is that the idle pressure is low but the rest seem ok. Do you know what grade of oil is in the engine? Just wondering if you have a very thin oil and that coupled with the miles could explain low pressure at idle. If the oil is a 10W40 or thicker then that wouldn't be the issue and I'd go with replacing the sender considering how little they cost.

[swimmer27]

If you go to the tvrsseries website then in the left hand column click on 2.9 Datasheet under engine and cooling it states Oil pressure 1.0 (2.5) bar which is 21.7 - 36.2 psi approx, is this correct?

[Jed-S]

The Ford quoted minimum pressure is 1 bar at 750rpm and 2.5 bar at 2000rpm.

I bought the exact same unit from the same seller on Ebay but it did not work on my S2, I added the extra wire to eartb but still the gauge refused to move so I purchased one from TVR Carparts which works fine, strange.
I get 18-20 psi at idle and 38-40 psi at 2000 rpm when hot, oil is Mobile 40w Car has done 98000 miles
idles smooth pulls well with no rattles or knocks.

Bump!
The eBay £14.90 sender from hosefittings UK worked fine for me, just need to run an earth lead to the nearby chassis earth point, & change the terminal end on the sender cable.
It was still the same price last March, include vat & p/p
