I decided to call my new (15 year old!) RRC 'Monty' There is a blip in the power now & again & he has told me it is a very slightly tappety. I think if its bad enough I'll stick a new camshaft in etc. Seems an easy enough job, I'll also swap the tappets & rockers etc. All seems easy enough (It's a LONG time since I did my 381 C&G, as I went on to become an electrical engineer as opposed to Motor Vehicle Technician!) How important is the pre-load on the tappets etc? What else would be required parts wise & is there any other (cheap) job whilst I'm in there? I want to sort the tappets out first, then borrow an ECU to try sort the 'missing a beat' as its already had a new dizzy, new rotor arm, plugs, leads etc. I can get a used ECU for £90 with a 30 day returnable warranty. I'm not suggesting the tappets/cam are causing the blip, but I really would like a nice smooth sounding V8 before I go any further, or am I talking bollocks & there's miles more important things that this???
Some kind of a checklist would be good, is the one on the Rover V8 site (rpi I believe) any good, or anything you chaps know?
Cheers
