Increased oil temp

[Phil G]

Noticed an increase in oil temperature at WightBlat and having just returned from a run to Goodwood the problem persists - I am getting worried.

 

1] Oil temp was always around the 80deg mark (12 o-clock) but now rising to the next marker which I assume is around 90-100deg.

2] Oil pressure dropping slightly but it could be me just noticing it more.

3]No discernable difference in water temp.

4]All okay when driving in traffic or at reasonably low speeds.

 

I did top up with synthetic oil before WB. I do not know what type of oil was originally used. Could this have an effect?

 

Any ideas?

Oh and its a 1.6 K series

I'd think ambient air temp might make some difference. The change in oil usually only affects if you complete an oil change and use diff viscosity. Possible causes, on my cars in the past are usually guages or more likely senders which are known areas of weakness.

As I had an oil temp gauge many years ago I enquired with an oil company what should the temp be, I seem to remember that a bit more than 100 degrees is no problam at all.

Not a very technical reply but the memory is not what it use to be

[Phil G]

Thanks guys,

 

So, possible sender fault which is a cheap thing to fix or don't worry too much. Now all I have to do if find the sender

 

I have been told that the K suffers from weak head gaskets which alarmed me some what However, if that was the case I would expect an increase in water temp also.

Also check that you've not over filled it following your top up.

[Phil G]

Ah now funny you should say that mav. I think it may be a bit full. Would this have an adverse affect?

Over filling will have a pronounced affect on the oil temp.

 

[Phil G]

Could be my problem me thinks.........

 

Should I drain a little or let it burn off?

I guess it depends how much is in there, and how easy it is for you to work on the car.

 

Personally I'd drain some out and then top up to the reuired level.

 

Are you wet or dry sump or wet with apollo?

[Phil G]

Wet with apollo.

ok. I'd drain via the sump and then refil gradually. I usually fill mine to about the 2nd x from the top of the dip stick markings (1.6K wet with apollo)

An alternative way of bleeding a little oil off is to take the pressure sender off (just in front of the filter). The hole to the sender is much smalller than the one to the sump so you are less likely to lose all your oil or get covered in it trying to get the sump plug back in while the oil is coming out!

 

Let it run into a cut-off plastic milk bottle so you can work out roughly how much you have drained.

Phil, FYI temp sender will be in the Apollo tank.

 

I think Mav has it right about the temp. The reason being that too much oil in the sump means it gets caught by the crank (windage) and gets hotter.

Thank everyone.

 

I will do as you suggest and see what happens. Alternatively, I could take this opportunity to do a complete oil change. And GET IT RIGHT this time 😬

Standard gauges/senders for Water temp and oil pressure are not the best, for a number of reasons, such as;

 

a) Senders packing up.

b) Instrument resolution very poor.

 

After making the level changes suggested above, if you still think there are problems you may wish to consider better senders and gauges.

Do a search - you will see what other think

Thanks MAK. Good suggestion
