Thanks guys. Had a friend listen to it the other night and he agreed that it sounded like one cylinder was not firing. His thoughts were an injector which seemed plausible but when I thought about it later I realised it couldn't be as I'm running single point log and the rough running was on gas too. Today I pulled all the plugs and they all looked the same, I had expected one to look a lot different. Couldn't see anything else so put it back together and started it up and it ran smooth as so took it for a test run and it seems fine now. Will keep an ear on it over the next few runs.

Good Morning. I noticed something odd with my Disco 1 this morning on the way in to work and possibly last time it was driven. It seems to be running odd upto about 3000rpm, I want to say it feels likes its not firing on all cylinders but I'm not sure that is what is happening as it doesn't feel rough enough. Get the revs past 3000 and it is as smooth as normal but below that it is almost hesitant and seems a bit down on power and lumpy (but a smooth lumpyness if that makes sense). My drive in this morning was mainly in slow traffic and under 6 miles so not really the ideal conditions but it did certainly feel different to normal. It was no different on petrol or PLG. 500 miles ago I had to replace the valley gasket due to a leak and it had been running fine before that and since until this raised its head. Where should I start investigating? Thanks

Thank you for the replies guys but in the end decided that spending £300 on a new pump and a new rad and getting it all fitted and working for a system I hadn't used for years was a bit of a waste of money. So I tracked down the correct length belt, the correct pulley and removed the pump. Now she purrs like a V8 should with no irritating squeal. If anyone else want to do the same the parts I used were: ERR6439g Pulley, ERR4461 Belt.

Morning guys. My aircon pump has decided that its new sole purpose in life it to irritate me by squealing. When I rebuilt to top end of my V8 in mid 2013 I ran in to a problem when it came to reconnecting the aircon rad as some grease monkey in the past had cross threaded all the ally connectors, this didn't really bother me as i hardly used the aircon anyway so just left it all loosely connected with the intention of fixing it sometime never. Now it seems the pulley on the aircon pump is squealing like a banshee and ruining the lovely V8 sound. As I've not missed the aircon i thought about removing the pump completely, that will mean a different Serpentine belt as the one I have would be too long. Also I think I might need a new tensioner but can't find an answer anywhere on line. Bit annoying as the current tensioner was new during the rebuild. So does anyone know the parts that I will need? part numbers would help if possible. Disco 1 Anniversary. 3.9 V8 Serpentine engine. Cheers Dean

Ive just been through this with my MGB. Heritage certificate was £50 well spent. Sent all the required docs of on the Monday and got the new tax disc and my docs back ten days later. My MGB was built in the middle of 73 but not registered until May 74 so would have caused me problems on the rolling date next year as well.

My own comic reading is decreasing and the only reason i have not unsubscribed is the Mike Manifold section, it is the first thing i read when the mag falls through the door. Dean
