shn7 Posted September 16, 2006 Share Posted September 16, 2006 Scenario. 1.8 K SS with dry sump (purple pump) Believed to be 72 degree stat. Oil temp sender in bottom of belltankhousing. Std Ali rad. Road use the coolant gets to about 80 and oil about 70 degrees. Track use, coolant runs to about 90 but oil heads towards 120 and looks like it would go further if I kept going. What's the best way to resolve this as clearly the oil temp is getting rather high? Steve. Not forgetting Percy the Polar Bear Link to comment Share on other sites More sharing options...
Normans_Ghost Posted September 16, 2006 Share Posted September 16, 2006 Steve have you checked the sender unit? Other than that it sound like an oil cooler needed but I don't think they all do that.

shn7 Posted September 16, 2006 Author Share Posted September 16, 2006 Norm, I've not checked it but have no real reason to doubt it as the behaviour is consistent. I suppose I could swap the oil and coolant senders (think they are identical). I wondered if a laminova would be better than and oil cooler given that on the road the oil temp struggles to get warm enough. Silly me sold an oil cooler that had sat on the shelf for years only a few months ago. Steve. Not forgetting Percy the Polar Bear Link to comment Share on other sites More sharing options...
Blade Runner Posted September 16, 2006 Share Posted September 16, 2006 Steve I have the cooler sitting on my shelf now as i never fitted it. No pipes though as Grubbster "borrowed " them when he fitted his Apollo. Blatmail me if you want it. Trevor Link to comment Share on other sites More sharing options...

Unclefester Posted September 16, 2006 Share Posted September 16, 2006 Don't ALL oilcoolers have a thermostat built in nowadays? normally in the sandwich plate housing.....

shn7 Posted September 20, 2006 Author Share Posted September 20, 2006 Trevor, Thanks for the offer and I may take you up on it but I'm not sure it's the correct solution as yet. I'm thinking that a laminova may be more appropriate to help get the oil temp up for road use and keep it down on track. Steve.

Blade Runner Posted September 20, 2006 Share Posted September 20, 2006 Steve No problem. Have you done a search for laminovas. I recall finding a few posts when i had problems. Trevor Link to comment Share on other sites More sharing options...

Paul McKenzie Posted September 20, 2006 Share Posted September 20, 2006 Oil cooler with thermostat for fit and forget...Laminova if you're prepared to 'tune' it after installation Paul Link to comment Share on other sites More sharing options...
shn7 Posted September 20, 2006 Author Share Posted September 20, 2006 Paul, What do you mean by tune it? Steve. Not forgetting Percy the Polar Bear Link to comment Share on other sites More sharing options...
John Howe Posted September 20, 2006 Share Posted September 20, 2006 Steve, senders for oil and water are common, have couple of spares if you needt to borrow them. Also have a new unwanted Laminova sitting on the self. Contact me direct if you are interested...

Paul McKenzie Posted September 21, 2006 Share Posted September 21, 2006 Ask for opinions on Laminova performance from people who have installed them and you'll get a variety of answers ranging from 'It works' to 'It doesn't work' and everything in between. IMHO that's because there are many variables with Laminova installation, such as Size of Unit, Installation location, and presence or absence of a variety of different water restrictors (see Think catalogue on website). For this reason the installation permutations are vast, and remember you don't have much hard data (oil/water temps and flow rates) on which to make your selections. Because of this I concluded that you'd have to be very lucky to get it right first time, and realistically you'd need to do a considerable amount of 'tuning' post installation. That's the reason I went for a conventional cooler and stat. Link to comment Share on other sites More sharing options...
Unclefester Posted September 21, 2006 Share Posted September 21, 2006 I had real problems with my Lotus twincam engined car blowing coolant out of the overflow, then overheating. I fitted an oilcooler with thermostat in the sandwich plate where the filter mounts (DemonTweeks..comes with braided tubes), then a Pacet type fan, as the original was junk and blocked the oil rad position anyway, but the thing that has finally cured it was a Polo Diesel spherical expansion tank mounted on the bulkhead. Now the water volume is bigger and the level is higher, all seems fine, it runs at a steady 165/170F and the level is always the same! Before I did this I had to top the thing up every time I used it, expensive in antifreeze. 😬 Blackout!!! 😬 😬here *eek* Link to comment Share on other sites More sharing options...
andymal Posted September 21, 2006 Share Posted September 21, 2006 Hi Steve Have you checked whether the rad is sludged up? I have the old rad of mine if you want to swap them over and see if it improves. I know the old rad was starting to sludge so it will not be perfect but is likely to have about 4 years less use (I think the cars are roughly the same age and it is about 4 years since i swapped).

Unclefester Posted September 21, 2006 Share Posted September 21, 2006 Not too hard to clean them out using a desludging liquid and reverse hosing till clear. Blackout!!! 😬 😬here *eek* Link to comment Share on other sites More sharing options...
shn7 Posted September 22, 2006 Author Share Posted September 22, 2006 Hadn't thought about the rad though my feeling is that it's not that given that the coolant temp isn't a problem. Steve. Not forgetting Percy the Polar Bear Link to comment Share on other sites More sharing options...
Unclefester Posted September 22, 2006 Share Posted September 22, 2006 Steve, Cheapest and most effective is stick a normal oilcooler on...they all come with a thermostat normally. Check DemonTweeks they seem good value, I fitted one recently and no complaints. Blackout!!! 😬 😬here *eek* Link to comment Share on other sites More sharing options...
