Don't recall ever seeing one in the flesh, but Haynes says it's on the left side of the block. I may be wrong, but I thought the filter was at the back on the opposite side. It should be pretty easy to recognise the oil pressure switch since the temp gauge and ECU temp senders would be way up in the manifold and the oil pressure switch should be the only electrical gadget screwed into the block.

Is it?

I've looked all around the area of the oil filter and can't see anything which might be a sender. I haven't looked from underneath yet though. I was trying to avoid doing that unless it was definitely under there.

Mind you, the car (the Tasmin) doesn't appear to have an oil warning light. It does have a seat belt warning light, but no pressure switches in the seats. So I was wondering if good old TVR used the seat belt light for the oil light just as on the V8S my 'MIL' light is the oil light.

Hi Joe,
The oil pressure sender for the oil pressure gauge is on the left hand ( nearside ) of the block on the 2.8 Cologne as per Mike's pic.

There is no oil pressure switch fitted for a warning light, but perhaps you could fit a tee at this oil gallery tapping point to fit one?

The thing arrowed looks like an analog sender for a pressure gauge. A pressure switch would be quite a lot smaller, but I wouldn't be surprised if TVR fitted the gauge sender where the switch was originally fitted. If you want both, it'd probably be possible to get an adapter to let you connect both sensors to the same port.

Yep, that is the sender for a pressure gauge rather than a warning light. There is a yellow light on the dash of the 2.8 but no connector for it. If you want a warning light then take that sender out and put a simple oil pressure switch in. If you want both then CBS do a T piece which can be used to fit both but there isnt a lot of room to do so, the gauge sender has to be parallel to the block if you fit a T.

The arrow is merely pointing to where the oil pressure switch would be if Joes engine has one banghead


A simple T piece can be fitted if you wish to have a gauge and a low pressure light, can't (be bothered to) find a picture of my S which has both but here's my Taimar, early Essex V6 but very similar location, with oil light and capillary oil gauge.....

I have just received a combined sender/switch from ebay. It is the correct 0-100psi/240-33 ohms for my car and switches at 11psi. Haven't put it in yet.
Item is http://www.ebay.com/itm/181762431983 (I don't know how to turn that into a hyperlink)
Sender goes front left as previously mentioned.

Thanks Dave, very helpful thumbup

Hyperlinks? Easypeasey...

Type [ , then type 'url' , then type ] , then type your word eg "LIKE THIS" , then type | , then cut & paste your target url to here , then type [/url] . Put it all together and it looks like this...

[u*l]LIKE THIS|http://www.ebay.com/itm/181762431983?clk_rvr_id=1115655270858&afsrc=1&rmvSB=true[/url]

I've deliberately miss-typed [u*l] to stop the link working and so you can see what it should look like.

It's a lot easier just to copy & paste the URL though laugh

My copy and paste seemed to put itself in correctly. Just didn't look like on the reply page.

Link has worked perfectly Dave, thanks.thumbup If that item does work accurately enough in your car please let us all know.type At that price it is a good buy. I know some of the Chinese stuff gets slated but most of the stuff I have bought direct from China has been very good value and I would go for one of these.

Well the pressure switch/sender is in and the oil light wired up. I don't have any idea what pressure the switch is switching at as I have much more than the 11 psi it is supposed to switch at. How accurate is the gauge? That's anybody's guess. I think it is reading a bit higher than the old sender was but I didn't go far, only into town and back (about 4km each way) to get some more terminals to wire up the switch. The water was up to temperature but I doubt the oil was. It was reading 75psi at about 2000 rpm. This seems high but I do have a Melling high flow oil pump. Also I don't know how accurate the previous sender was as it was a cheap Chinese sender as well. I don't expect these gauges to be super accurate so I am getting a good indication and once I am used to where it is sitting I will know if it changes. If the sender fails again hopefully I will still have a light that works.

By coincidence I noticed an oil leak from sender on my 2.8, it's perfectly positioned over the exhaust so that a warning wisp of smoke gives notice of the leak!
