Sensor problem?

[RAIDEN]

Ive got a MK2 16v with a problem.  After using it for 40mins the oil light came on but there is oil and water in it.  my uncle who I got the car off sez it happened to him months ago and that it woz a dodgy sensor but the thing that bugs me is that the engine temp gets to 100 degreass in 10mins.  should i worry?

is your fan kicking in?

[RAIDEN]

Yep the fan still works

[monkeyalan]

when the fan kicks in does the temp drop a little? If so my next port of call would be the thermostat. If the temp is genuinely high i doubt it's the sensor as i think that just monitors temperature. i'm looking at a mk3 manual for this so i may be wrong.

It does drop. the highist its got is 108 then i drove slow and it went down to 92.  should i take it to a mechenic??

[monkeyalan]

depends how much you can do yourself. If you can get the thermostat out, test it by putting it on some string and dipping it in boiling water. if it doesn't open it's knackered. if you are going to drive it i'd take it short bits at a time as letting it get too hot is very bad.

Cool ill give it ago. thanx

i assume your talking about the digital oil temp reading on the MFA? 92-108 is fine. thats normal temp for them

If u say thats normal then thats cool.  anthor that bothers me tho when I timed the car the temp gets to 80 in about 2mins.  is this normal?
