Oil temps

Post by 58splitty » Sat May 11, 2019 8:35 pm

So, i have a 1600 running 40 dels and my temp is only 70-72 max, Ive tried 2 senders one vdo and one other and 2 different gauges and they both read they same, and they are reliable units. It does seem extra low but should i be concerned or have i created an efficient engine?

We have a 1600 with 34 icts and in this weather even going at 60mph for hours on the motorway the gauge never goes above 60/65 degC. But if the outside temperature goes up 10 degrees your oil temperatures will go up by at least the same amount. Also fully loaded, long hills etc will push temps up. The gauge in our bus reads up to 100degC+ on a long drive fully loaded in southern Europe in the heat of summer. And when you pull off the motorway after a long slog and stop at the lights for a while just watch your oil temperature climb!

Our bus has a deep sump, I think that makes quite a big difference due to the extra finned surface area in the air stream.

Partly it'll depend on where your senders are fitted. But also, CR. Type of heads + exhaust fitted. Timing settings. Fuel settings with those oversized carbs, tinware type. Thermostat fitted / working flaps etc etc

I niticed mine goes up about the same as the temp rises outside to. I shant worry, it sounds as if its correct then as ive set all the other stuff up correctly.

Just wondering, what is a temperature you should start getting worried, and could cause damage to the engine?

And what is the max revs and cruising revs of a vw block?

Cheers

I was told that the optimum revs for an Aircooled engine is 3500 rpm.

You really want the oil to reach 80-90 so it's at operating temperature and water is dispelled.

Revs - absolute max revs is 5k and when cruising max 4k (if you have any degree of mechanical sympathy and are not deaf you wouldn't get past 4k anyway!)
