On start up (especially when cold ) the white smoke which almost goes after a few minutes, but a heavy bit of throttle and it does smoke (but not blue or black still white). Also does not seem 100 percent smooth , possible one cylinder (or more?) not firing? ...so starting with simple items and I did try small change on dizzy advance , putting in injector cleaner in the tank, the Italian tune up ( but bottled that after I think the neighbours think I,ve set fire to the garage). The air con is out so I can get to spark plugs...some were a bit oily ( not yet re-checked after running for a while.) Crank Breather cleaned...did look at fuel vacuum in boot but possible need to take things apart a bit to see behind it and if it's correctly connected. So next steps? Check all spark plugs, compression test, check injector (listen with screw driver to ear listening for clicks? Buy a noid tester, clean injectors (bit scary taking off fuel line off the top?...ummm what's simplest try try first ( or should I lie and get RAC home start and say it drove in OK last night!)
Had a Mk IX that'd been part of a collection for 12 or so years (53k miles only documented for a '59MY). It'd start but virtually immediately oil up the plugs. Change the plugs and it'd start, run and then oil them up again after a few mins. Eventually found out that engine oil seperates after a time of stagnation, and it'd carbon up the plugs.
So use a Meggar on them (a 600V one will do -- I had one left over from my ships' servicing days). If there's any sign of leakage then ditch them. And get that engine oil and filter changed. It's gotta be done anyway. Use a fully synthetic
How's your coolant level? Has that been changed, flushed thru? Any bubbles in the header tank when you leave engine running on tickover? Does the white smoke eventually lessen when engine fully up to temperature? What does the white smoke smell of?
Keep us uptodate?
