front hole not plugged .. I accidentally broke the hose twisting it off cover / dried out

put fresh new hose to air box .. air box does have a slight bit of oil drip from that hose



rear valve on head cover was very grimey .. pulled it out, sprayed it clean ..in/out

any tips to check if a bad valve? not sure how it works

it does have vacuum / engine running .. I put my finger on its engine side vaccum port .. idle slowed down alot /bogged



got new o-ring for oil filter adapter .. changing oil tomorrow, might as well do it .. just to do it


I did one years ago .. cant remember .... hex key thru the L (where adapter bends) to motor ? what size bolt head? 1993 HO 4L

I also thought there were 2 o-rings .. parts store only have 1 .. looks like a 1 piece elbow to filter / motor

thanks in advance
