greetings all,

in practice do you really need to re-adjust hydralic valves after replacing
push rod tube seals?  this will be the first "real" engine work i've done
since acquiring my 80 westy (only a couple months ago)  so i'm a little nervous.
 read the replacement
description on type.com tech files.  seems replacing seals is easy enough but
i'm afraid if i mess with the valve clearance i may screw things up.  

also should having non-leaking push-rods clear up the air inside the cabin?
I 've noticed lately a oil smoke haze when using the heat lately.  any way to
clean out the heat exchangers w/o removing or is this wishful thinking?
heat exchangers seem complete and not rusty.

thanks for any info.
