im going to replace my valve stem seals soon without taking the head off, but yeah if you rev it nice n slowly it will be fine especially when cold....rag it and look thru your rear view youll see a cloud of smoke i did a comp test on mine 200 across all cylinders, plugs were black...the previous owner didnt drive the car as hard as i do thats why it wasnt apparent when i first got it + the crank seal was leaking so i had oil loss anyway if you want get some heavy weight oil from morrisons (asda dont have it) get 15w50 its really cheap apparently to tide you over check the oil every other time you drive and youll be grand till you can afford to fix it
