I have a 98 legacy with a transplant motor. It is a n ej22 HLA OBD2, so maybe like 95 or 96 I guess, anyways I am having trouble getting the HLA's to "pump up". I had one that was ticking real bad, removed it, it was sticky so I cleaned it up now it is springs up but no luck in submerging it into oil and pumping it to get it hard. Am I using the wrong technique?

Thanks for your help

There isn't a lot to the technique, so if following the procedure in the link below doesn't work, either the HLA needs further cleaning or the surfaces no longer are mating well. If the latter, it's best to just replace it.

There is a check valve in them. You have to "open" it to fill them with oil. Use a pin to poke the plunger in the bottom of the HLA while compressing it in oil. This will release the goopy old oil inside, and let it fill.

 

They should not be "springy" when you are done. Should be pumped up real tight....just barely able to compress by hand.

 

That is why EJ HLAs are so much better than EA. The Check valve in them.

Thanks, In the haynes manual it doesn't tell you to depress the check ball, that will make all of the difference.

Will try that procedure this afternoon.

 

Thanks, Dave
