Hi All Part ERR4686 arrived and fits perfectly. Thanks for all the help...much appreciated Dave

Thanks Discool....I'll order a ERR4686 and see if it fits. The ERR4686B is a Brass version and the ERR4686 is the plastic one. Will let you know how I get on Cheers Dave

It is bizarre...I've been thru Microcat and the full parts PDF files from lrservice.ru and I don't see this pipe. It does exist, believe me. Here is a photo of the 3.5 V8i in the 1992 Disco before I remove the inlet manifold. Dave

Hi The picture is just for illustration purposes. The engine is out of a 1992 Disco 3.5 V8i and I've planted into my 90. The cap that I need is made of plastic. The err4686b part is the brass radiator cap and does not fit :-( Cheers Dave

Hi I need to replace this plastic cap on a heater pipe going to the heater matrix. See the attached photo. What is the part number and where can I get one? Its made of plastic and the last owner mangled it with pliers or vice grips. Cheers Dave

Thanks for the response "eightinavee". It's kind of what I suspected. To fit the AFR gauge, can I use the sensor of the EFI system, or do I need to fit a new sensor? Cheers

Hi I recently purchased a 1992 Disco 1 V8i, with the Hotwire system. There are no cats nor Lambda sensors, so its running on Open Loop mode. The wagon starts first time, no matter how cold the weather. It runs very well and revs all the way up to about 4,500 rpm, where it goes not more...
