Hi Guys

I am running my b210 after a rebuild these days i am on the process of test run, there are few issues about to be verified

1.after running about few kms i notices a strange noise from the rear side when moving bumpy roads,came and checked and noticed that oil has leaked down towards leaf spring from both rear shock absorbers, what is a good brand to buy set, is KYB ok ?

2. i got a burned head light ,it has become milky white color inside the glass and none of the pilamant are working why is that ? is it wiring issue or water or anything else ?

3. for some reason i have not closed the Heater side water outlet from the back side of the engine,for all these days,radiator water level did not go down even though i did not run the car i have kept it on start few times earlier ,but today i have noticed all water has gone out from that outlet i must have run it about 6-8 km( i dont know whether it has overheated becs i did not fix the dash board yet) ,will that affect my gasket later on ? but after that also i filled water and started it and kept few minutes so far no sign of gasket failure,

4. i have voltage meter and AMP meter on my b210 ,when idling voltge meter stays arround on 13V and AMP meter reads 0 , on 1200 to 1500 rpm voltage meter moves to the 14 + and AMP meter stays towards positive side of the guage, when head light are on voltage meter reads 12.5 -13 V and AMP meter reds little below zero , is it ok or do i need to adjust it from voltage regulator ? ( i have replaced everything to the alternator with brand new parts)

thanks
regards
