DC Posted September 12, 2002 Share Posted September 12, 2002 I have just returned from the Caterham showroom, and have had a fantastic test drive in the R300. The engine is glorious, revving up to 8000, the handling superb with the new 15" Avon rubbers and the sound is out of this would (if a little loud). It really is the best Caterham I have driven with one reservation, there was a smell of petrol on the overrun. Jason informs me this is a trait with roller barrels, but I know that my dear wife would not put up with such a whiff. Is there anybody running an R300 that has the same problem, or was it peculiar to R300XPR? Dave C WEL653 Link to comment Share on other sites More sharing options...
mav Posted September 12, 2002 Share Posted September 12, 2002 May also be the breather letting a small ammount out (from the Tank). This is a well documented problem with the K series cars Link to comment Share on other sites More sharing options...
Peter Carmichael Posted September 12, 2002 Share Posted September 12, 2002 I am wondering what it is that you were smelling because engines of this type needn't be that unsociable smelling. There is the possibility of stand-off, but the R300 cams are not excessively wild so I wouldn't expect much fuel to appear at the trumpets. It is more likely to be a faint whiff coming from the engine catch tank vent, which will be a smell of burnt fuel and hot oil or a leak from the fuel tank breather - these have been known to be open, resulting in fuel spillage. Not sure if the R300 runs a charcoal cannister and purge valve but I suppose these could be responsible and related to fuel tank venting. Link to comment Share on other sites More sharing options...
Red SLR Posted September 12, 2002 Share Posted September 12, 2002 Mine stinks! I think its a combination of the exhaust and fuel tank vent! No charcoal canister either. Simon. See X777CAT here Link to comment Share on other sites More sharing options...

DC Posted September 13, 2002 Author Share Posted September 13, 2002 Simon, when you say that yours stinks, are you yet running on the road? (love the build diary and the grease girls) I have been speaking to two friends who have SLRs with roller barrels (in effect R400s) and they don’t have the same problem, although one had a slight smell until the ECU was remapped. I think I will have to have a word with Minister. Dave C WEL653 Link to comment Share on other sites More sharing options...
Bafty Crastard Posted September 13, 2002 Share Posted September 13, 2002 Simon Was today Friday, now Wednesday 16th. I understand Mr Caterham is looking at your problems next week, keep us informed on the outcome. R300 NUT Link to comment Share on other sites More sharing options...
