OIL Temperature

[LCR mat]

when your oil pressure goes low on most cars the light goes nuts on the dash

the easiest test would be to unscrew the sump plug & go for a sporting drive - if no oil light shows then I'm wrong & I'll buy you a pint

if the oil light shows, then you should have stopped earlier - your engine has no oil pressure!

dont know if this is true but i was told that the warning light on the dash for low pressure is set for idle so if it comes on while on throttle- bye bye engine (idle pressures seem to be about 2 bar- on throttle anything up to 8 bar)

just thought id mention before I changed to quantum synta gold id get oil pressure on WOT of upto 10bar.
also after ragging it would drop below 2bar far more requently when returning to idle

Steady motorway journey too and from scotland over the weekend and normal operating temp was 120 C.

I wasn't giving it beans and i never went above 3500-4000 rpm in any gear.

I really need to get comparisons of other chipped LCR's oil temps to compare with mine.

 

[m0rk]

nowhere near that high. either something's wrong, you're using the wrong oil or your version of steady is different to everyone elses

(or the guage is wrong?)

really should look at an oil cooler if that's just cruising

That is very hot. I hope you are on high quality oil with regular/6 month changes.

i have heard of comparible temps on chipped 1.8T's. seems the norm from what ive heard. Question is is it damaging or just normal for the engine???

 

[Mitchy]

I'll do an oil change this week to see if it helps.

I averaged 34.8mpg over 330 miles on the way up and 32.9mpg on the way down so i've been taking it very easy and still 120C

I'm not to sure if the temps would be different between LC's/LCR's and chipped examples of both

Perhaps i should change the sender or buy another gauge to compare.

If i give it the beans and high speed stuff, it will rise to 150 C 120 C is normal operating temp it seems

Ive thought about a cooler but will the engine bay allow any room for 1?

 

[edc]

If you are seeing 150c regularly then I would check asap to see if your oil is capable of providing any sort of protection up there without breaking down.

 

[Mitchy]

Not regularly mate, only if the car is pushed hard. Revving hard and travelling at high speed it will rise to 150 C but never seen it go beyond that. 120 C is regular temperature.

Im getting a bit worried about this now as if its not a dodgy gauge/sender then i doubt im the only chipped LCR owner suffering from high oil temps

 

[edc]

A handful of times before the next change is enough to be regular

If your oil temp goes up to 150 deg C is your water temp not up pretty high aswell and the high temp alarm not sounding?

 

[m0rk]

water temp is not the same - that has a radiator & is used to cool the block

when on track my 16v bouncing off the limiter in each gear got to 128C pretty quickly, but I backed off & came off, water temp was still where it should be

99% sure you could look at oil temp on Vag-com, so it'd be interesting to compare on that

@ Mat - just because other people have it doesn't mean it's right.... just means they're mutually ignorant.

oil cooler anyone?

I was looking into one for the summer.

A nice RS4 one which should be direct fit.

The only real problem i seen was the lower intercooler crossover pipe. As the lcr has a rather long oil filter.

However this can be solved by using a pasat oil filter.

I know but, would the hot oil/engine temps not effect the water temp?

 

[m0rk]

the water has a 6ft square radiator.

 

[cuprabaz]

Ah good point! i'll go back to sleep

If the temp sensor is reading wrongly though - you might see the same temps through vag-com.

 

[LCR mat]

Dont know of any block to log oil temps

Oil cooler in my case will be fitted where the left hand Inter cooler was.

dint say it was right for them to be at these temps, just that it seems the norm. the question I posed was is it dangerous for the engine? or could it be that these operational temps are not harmful to the engine.


I wonder if these higher temps make the internals(such as conrods) weaker???

 

[YerMother]

How would you connect up the oil cooler? Where would you take the feed and the return from?

 

[m0rk]

The higher oil temps means the oil is thinner turning to vapour, so it just won't lubricate, then inturn the friction will build up causing wear / ceizing.

friction causes geater temps- higher temps will weaken the metal- possibly leading to bent conrods???
