5.9 valve seal install

Worked at a O 'Reillys. Tried to use(actually bought that one). Locked up,on initial tryout. Threw that ,in the trash ,immediately. Ran down ,to the local Napa. Napa/K.d. tools(same piece),about 30-40 bucks.And well worth it. The last thing you want to do,is fumble with a bad tool with valve spring pressure
I am as cheap,as they get. Not here,not worth the frustration. I recommend ,buying/borrowing a Kd tools 2078. Night and day difference..
