i will try that , is there way of testing the sender?ive checked the price of the sender, its a fortune . is it a land rover part ?

[slideways]

not sure about testing but the terminal gets all corroded and gunked up with crap. i degreased mine and cleaned with wet and dry then alittle copper grease

Er, have you checked the oil level?

If she hasn't vandalised herself already it is probably the sender, or the connection(s); the RV8 is pretty solid. But, however unlikely, it cannot hurt to start with the basics?

Best of luck.

I had this a couple of weeks ago... Sender was knackered and needed replacing. Its not a Land Rover part, or at least my motor factor said it wasn't, so I got one from a TVR garage for about 40 quid IIRC

Mine did the opposite, read 90psi all the time, heres the thread that may or may not help......

The same happened to me a few weeks ago

A little bit concerning at the time

As long as the oil pressure light doesn't come on at the same time then the oil pressure is probably OK

I ordered a new sender from TVR parts as found it to be the cheapest. There are 2 types and they will help in determining the correct one.

I changed mine in 5 minutes with no loss of oil

Hope this helps apparently it is quite common

Must be the week for it.mine has a very solid 38lbs with about 30lbs warm on idle.last week it started hopping all over the place from 38 down to 20 and back up again.no oil light on or any loss of oil or power.is it fair to assume it is safe to drive as i assume ( not Being a mechanic )the engine oil pressure is fine and its just the instrument thats showing a odd pressure.

Yeah it'll probably be fine. I checked by opening the oil filler and verifying that there was plenty of oil on the rocker assembly, then made sure the warning light came on with ign and went off when started. My gauge dropped to 0, then shot off the scale and stayed there until I replaced the sender. When it was off I looked at the terminal and it was loose from inside so I think the unit had just broken down over the years. Putting a new one on was really easy and fixed the problem straight away. I'm told they are susceptable to water, heat and vibration - perfect then for the bottom of a TVR engine! I'm surprised mine lasted 11 years!

thanks for that.

Well if there was no oil pressure then none would get to the top of the engine. So by checking through the oil filler, you're making sure there is oil present around the rocker assembly; so you know that there must be some oil pressure.

If there was no oil pressure the lifters would clatter too (Assuming they're hydraulic)

[daz the plumber]

that was from tvr shop

I agree with WOO51E - If your oil warning light isn't coming on then there's almost certainly oil pressure there. Do check though that the light comes on when the ignition is turned on before starting.

If you're still coming over to my place on Saturday to go through your fuel problem I can test the sensor for you before you invest, only to find it's an alternative fault.
