Hi ! I have a 97 sephia . I need to replace the valve stem seals on my 1.8 dohc fuel ing. Engine ! I am trying to do this without removing the head ! I have the air tool hose that threads in the spark plug hole so that the valves will not fall through ! My problem is finding a valve spring compressor tool for that ! The tools i have seen at the part stores are all for ohv instead of cam ! There was one i came across that levers by hand but because of th size of the tool it will not work ! Please help an advice asap !
