  right then after my previous thread ,,
i know this is long but bide your time !

 i have got my car started and sounds sweet as u can imagine im very pleased  
 took a while to start but did kick in ,
  charged the  battery  and checked the earth straps and gave it a go and fired up she went .

    right then now for the bad news ,
  1 ,  oil leak on the breather from the sump
  2 ,  slight tapping noise .sounds from the bottom end as ear to sump ,
  ,
  i have put 15/40 oil in at the mo and going to run it a while then drain it while red hot to clean it out as water could still in places ,
  what grade of oil would you reccommend?
 thanks ,

10/40 vaux semi syn  

  daft question but how does the grade work with the thickness ??

[markey mark]

Drain that goo out (15/40) as is no good for the mig engine at all it don't lik it. Replace with 10/40 which is recommended from vx. If you are getting a knocking noise from the botoom end that could be becuase you have pu 15/40 in on the other hand it could be th oil pump onit's way out. The tapping noise you are getting from the top end could be a hydraulic lifter rattling but will go quiet after a few minuetes. The oil leak could be the crankcase breather not done up enough. I am sure someone else will be along to say something else.

I think its something like 10 is the thickness it is and the 40 is temp it is ok to as -40 i think. Someone else will be along soon to give accurate  info

  good question , i checked everything and gave it a whirl and she fired up took some time ,
  the oil def coming from breather tube  and tight , going to replace the gasket , , is 10/40  thicker than 15/40 ,  
   i took the rocker cover off after letting it run for a while and get to temp and found slight gundge still , so just wondering if water could be in some places ,
   going to use the oil in to flush it out !!

Yes 15/40 is thicker than 10/40. Did you check the crankcase breather tube was clear?

Did you use a new gasket on the breater tube that bolts on the crankcase at the back?

I always thought the numbers related to the viscocity of the oil at operating and room temp. So 10/40 would be thinner than 15/40 at operating temp but the same when cold.  I could be mistaken though
