I run a sandwich plate thermostat and all the rest of the kit including the Maxi 3 pump. Best bit was you can fit it without taking the engine out but you need an angle grinder and a welder for the support bar. Today after a run on the motorway the oil cooler hoses downstream of the thermostatic sandwich plate were just warm to the touch . The dipstick sender said 80 degrees C . It maxed out at 90 degrees C foot flat on the floor going uphill at 65 on the M27 this evening. Pre oil cooler upgrade thay would have been 110 to 120 degrees.
at 80 degrees the thermostat will start to close i guess or the sender might be measuring the oil temp coming back from cooler into the engine before it goes around again.... then again i could be wrong!!!!
If it's a VDO gauge, then they are notoriously wrong... Volksworld did a comparison test and the VDO gauge was around 10°c lower than actual
Sadly my VDO gauge was only about 2 degrees out around 110degrees C when I checked it against a reasonably accurate digital thermometer. I think that just having the full flow filter in circuit is enough to account for the cooling I am seeing. I may have to go back to 20w/50 oil and start tuning to run a bit leaner. I began the excercise with really hot temperatures round 122 degrees . With the oil cooler it dropped. With jetting changes it dropped. With thinner and more oil it dropped. Also at the moment there is so much traffic on the M27 that I can barely get to 65 mph before I am getting too close to the car in front in lane 3...
postie arrived with some of my cooler set upand from what i can work out with the thermostat valve it works like this, when oil is cold it comes in the top of the stat head and the valve is open which allows oil to flow separately to the cooler loop and past the valve down to the filter mixing with oil from cooler and then back up middle of filter and then back to engine. when this valve warms up it shuts of flow down to filter and only allows it to the cooler loop and then the filter on its way back to the engine. i had to think for a while because i thought it stopped it going to the cooler while it was cold but the way i look at it, it just splits the oil flow 2 ways
Yep I think that's the idea, not really ideal? I have a seperate thermostatic vlave that behaves the same, almost as if the manufacturer had little faith in it? It splits the flow like yours relieving the pressure on the filter, but not cutting it off completely so a lot of the oil is still getting cooled when I'd rather it wasn't. I have yet to see how fast I have to go to warm it up in the winter but I fear I'll be back to wrapping the cooler in bacofoil.
most people use fram hp1 filters but are there any other suitable filters that can be used. £25 for a filter seems a bit of a price to pay..
Any old filter will do. I believe the fram are high throughput (high revs) and have built in pressure relief which you won't need with your thermostat. Oil filters are much the same (I hope). I just get a big Wix one that fits with no valves or fancy stuff - approx £5-10.
I'll have a butchers at the number tomorrow. I specced it in the shop with filter head thread/sealing size then found a suitable big one (assumed big is better) without frills. That's no anti-drain back and no pressure relief.
I have a different head though I expect same spec... You'll know yours, Mine's an plain empi one like VW Heritage sell.
centre thread is 3/4'' which is the same aswell as most fords use so i would of thought plenty of filters would fit on.
I was lying right next to it today, now it's parked in a field. You could just pop to your motor factor and choose one?
