Gary-Cornwall Posted November 27, 2002 Share Posted November 27, 2002 Does anyone know if the original 2.0 16v Vauxhall engine needs an oil cooler to run in the 7 (standard on Webbers)? as I'm currently upgrading from the 8v 1600 engine. Link to comment Share on other sites More sharing options...
Paul McKenzie Posted November 27, 2002 Share Posted November 27, 2002 Not normally, or so we are led to believe. I am in the process of fitting a temp. sender to find out what really happens. Paul Link to comment Share on other sites More sharing options...
Alex Wong1697456877 Posted November 28, 2002 Share Posted November 28, 2002 I don't think an oil cooler is needed. Mine's done 35,000 miles without one. Link to comment Share on other sites More sharing options...
ian balson Posted November 28, 2002 Share Posted November 28, 2002 Gary, I run a std HPC 175bhp VX on Webers. No oil cooler in std spec from Caterham. Paul, how/where are you fitting the oil temp sender? Thanks Ian HPC150 ian_balson@yahoo.co.uk Link to comment Share on other sites More sharing options...
Paul McKenzie Posted November 28, 2002 Share Posted November 28, 2002 Ian, To avoid having to weld a boss onto the wet sump, I got a new sump plug and had it drilled and tapped to take a standard water temp. sender. I will now connect this as recommended by Dave Kimberly through an on/on switch on the dash so I can switch between water and oil temps. on the existing water temp. guage.

Chelspeed Posted November 28, 2002 Share Posted November 28, 2002 My Vauxhall on injection with no internal mods was allegedly making 208bhp. I fitted a temp gauge and the oil temp was up around 120degC most of the time. I fitted an oil cooler the next week. Link to comment Share on other sites More sharing options...

Paul Deslandes Posted December 2, 2002 Share Posted December 2, 2002 I had serious low oil pressure problems on my 16v VX on the track until I fitted a cooler. All the experts (!!!) said it wasn't necessary but it made the difference between 60psi and 20psi-and-falling. If the problem wasn't temperature it could be that the extra capacity of the cooler and external oil filter improved the availability of oil to the engine which runs on wet sump with foam insert. Either way, the cooler did the trick and no more anxious moments!! Link to comment Share on other sites More sharing options...
Paul McKenzie Posted December 2, 2002 Share Posted December 2, 2002 Paul, Where did you get your cooler and how much Thanks, Paul Link to comment Share on other sites More sharing options...
stevefoster Posted December 3, 2002 Share Posted December 3, 2002 I don't run a cooler and have carbs at the mo'. My wet sump system ran at max 90 degrees. The Dry sump system I have now runs with more oil etc and hits about 85 degrees max. Both in lap after lap track conditions. /Steve My racing pics, 7 DIY, race prep.

Paul Deslandes Posted December 3, 2002 Share Posted December 3, 2002 Paul Think Automotive in Isleworth have everything including the cooler, external cartridge oil filter, sandwich plates, temperature takeoff if needed, hoses etc. I can't remember the prices but as I did the job three years ago they have probably changed anyway. Best is to look at their website www.thinkauto.com. I mounted my cooler in front of the rad using ally brackets that I made up and bolt onto the radiator av mounts. Had to use a slightly shorter av mount to avoid fouling the grill. Other wise pretty easy to fit apart from the filter which was a b....r! If you decide to go ahead email me at pauldeslan@aol.com and I will email you some digi pics of my installation. Link to comment Share on other sites More sharing options...
John_Salmon Posted December 3, 2002 Share Posted December 3, 2002 Gary I run a VX 2.0 wet sump without oil cooler using Mobil 1 15/50 and had various oil preassure problems. I have now fitted an Apollo tank with a remote filter. The oil preassure is now improved and constant Link to comment Share on other sites More sharing options...
Paul Deslandes Posted December 4, 2002 Share Posted December 4, 2002 That's very interesting John 'cos I think that may bear out my theory that lack of oil, or rather, lots of it in the wrong place, may be the cause rather than temperature. The interesting thing was that the pressure would drop after a moderate period of high sustained revs, e.g. Lavant straight at Goodwood, and return to normal very quickly after slowing down. Having since fitted an oil temp gauge it is obvious that the oil temperature takes far longer to cool down than would account for the rapid recovery in pressure. Paul, I would try John's tank method first, or fit an oil temp gauge to be sure that temp is the real problem, before lashing out on a cooler. I know there are lots of people out there who have never had this problem, even though they drive extremely hard. I wonder what the variability of the engines is to cause this.

John_Salmon Posted December 4, 2002 Share Posted December 4, 2002 After a high speed run the tappets would be noisey and the oil preassure would drop,although after a short period at idle afterwards all would be ok. Fitting the Apollo must be removeing air from the oil. Rember most VX2.0 run dry sump anyway so do not have this problem. Link to comment Share on other sites More sharing options...

Paul Deslandes Posted December 5, 2002 Share Posted December 5, 2002 The frothy oil theory might also explain why some oils seem better than others. ie they are more or less inclined to froth. As a matter of interest John. how did you install the Apollo tank? Is it line with an external filter bowl, similar to a cooler fit but with the tank instead of the cooler? I find this subject quite interesting because I had some really scary moments with my car on the track and I know others have had the same problem. If we know the correct explanation we can advise accordingly!! Link to comment Share on other sites More sharing options...
John_Salmon Posted December 5, 2002 Share Posted December 5, 2002 Paul Sandwich plate preassure side to top of Apollo, bottom of Apollo to "in" of remote filter,mounted between rad and rack,"out" of filter back to sandwich plate. The sandwich plate is capped with a blanking disk supplied by Think Automotive. I also fitted a one way valve to the vent pipe to prvent drain back. Seems to work well !!! You can now fit a bigger size filter. Link to comment Share on other sites More sharing options...

EFA Posted December 8, 2002 Share Posted December 8, 2002 Graham, I do not get over 125deg C from my crankcase mounted (SPLASHED not imersed) sender after 20 mins thrashing on the track. I think the low pressure is a factor of 0w40 and 5w40 oils which are too thin at higer engine temps. 15w50 seems to cure the problem.

Paul McKenzie Posted December 8, 2002 Share Posted December 8, 2002 Arnie et al, The one thing which seems to be missing from this discussion is what temp. is "too high". Has anyone had any sensible response from either engine manufacturers or oil companies as to what is the optimum oil temp. for engines, in particular, the 2.0 XE?
