Bob_Rich Posted July 19, 2009 Share Posted July 19, 2009 Lo all U K series people. Firstly this is not a question about a Lotus or Caterham 7 but about a mate of mine with a bad problem on K series engine used in an 02 Landrover Discovery. I though some of U K series folks might have a few ideas even though his is an engine to a cooking spec. Basically it started to play up ( missing, smell of petrol, and not pulling well ) this was initially intermittent got worse over 2 days and then it finally stopped with the engine management light flashing rather than on hard. On examination the cat which had been fitted new only a few days before (because of a small crack found while a tyre was being fitted) was so badly melted inside that the innards had been burnt up and blown out and blocked the exhaust pipe. A new cat has been fitted and both the ignition coils ( is has a twin coil wasted spark type set up no distributor) changed but there is still some evidence of a slight misfire and it is not pulling well. Computer does not seem to show anything logged problems ANy ideas form those woith K engine experience?? cheers Bob Link to comment Share on other sites More sharing options...

Colin Mill Posted July 21, 2009 Share Posted July 21, 2009 Well, it might just be the vacuum pipe to the fuel pressure regulator split or come off. Although not on a K series we had this on a pals BMW 525 only last week. It was massively rich simply because the fuel pressure was being set relative to full atmospheric pressure rather than the manifold pressure (this would be OK if you could keep the engine under very high load all the time but the BiB seem to take a dim view of this sort of driving 😬) Edited by - Colin Mill on 21 Jul 2009 08:56:31 Link to comment Share on other sites More sharing options...
Frying Pan Posted July 21, 2009 Share Posted July 21, 2009 We didn't fit K-Series to Discovery. There was a 2.0 MPi model which used the T-Series engine - do you mean this, or perhaps K-Series in a Freelander? If it really is a K-Series in a Discovery, it's going to be working pretty hard... -----See some pictures of the build here. 16000 miles completed!

Bob_Rich Posted July 21, 2009 Author Share Posted July 21, 2009 Sorry about that!! I did mean a Freelander. ( its not my car and so I got the names wrong but it is definitley the 1800 K series engine without VVC) It is currently at garage and problem is proving very difficult to diagnose so comments thus far have been helpful. cheers Bob Link to comment Share on other sites More sharing options...
