the old xr3 drove no bother this morning up to a mates garage, it sat for about an hour then i got back in turned her over & it started missing on a the 4th cylinder so i changed that plug as it looked burnt out & changed the leed & gave the distributer a wee sand with sand paper, checked for spark...no problem there but its still missing, she's been ticking away lately & theres a bit of blue smoke so im thinking valve stem seals but can they be so fucked that its filled the cylinder of oil as the plugs a bit oily???

i just need the car running for another week or 2 so a quick fix is needed

 

If it is valve stem oil seals you can change them without taking the head off. You can buy a special tool for doing them. If they are worn badly they could fill the bore with oil.

 

Where can you buy that tool mate. Cos i have a orion mk1 that needs a few newones

 

a mate has one but im just doing the whole engine & going for a turbo engine & box
