Anthony Posted January 17, 2003 Share Posted January 17, 2003 I have a VX with std Caterham oil pump/basic dry sump system. Has anyone had any experience with the oil pump failure ( ala K-series ) on VX engines in competition/track day use ? Apologies if I am being completely paranoid.

ECR Posted January 17, 2003 Share Posted January 17, 2003 I assume you are talking about the 16V 2 litre... Never actualy met anyone who has had a failure with the VX oil pump but it is good practice to swap the inner gear (which is sintered) for a steel one (just to be safe). Swindon also recommend swapping the pressure relief valve piston for a "plastic" one as the steel ones have been known to sieze. If the engine is to experience very high revs then cavitation can be a problem and the pump gearing can be reduced. Not heard of or experienced any problems with the Caterham scavenge pump (other than the drive belt coming off). which was quickly spotted and rectified.

EFA Posted January 18, 2003 Share Posted January 18, 2003 Anthony, Dave Brown had the std pump gear shatter I think. Regarding Rogers comments, I do not think it possible to adjkust the gearing on the std pump - for high RPM you should look at a 3 stage external and a blamnk cover plate for the front cover. Pace do both of these items. Arnie Webb The Fat Bloke back @ 512k Link to comment Share on other sites More sharing options...
StewartG Posted January 19, 2003 Share Posted January 19, 2003 I suspect some of the plastic pressure relief valves cause more problems than they solve. Just make sure the original is in good condition and nicely polished for smooth operation. Link to comment Share on other sites More sharing options...
