I'm thinking of building a valve spring compressor tool....

... that will allow you to remove valve springs while the head is on the car.

I have an old rocker shaft I can use so I don't scar up my good ones. I'm looking at making it to replace valve stem seals.

That said, what kind of seals does a B3 have? Just umbrella seals? Or are they posi-lock seals?

can't you just use this?

spring compressor like you describe already exsists. Its part of the original factory tool kit for the Tracer. Prefix for the kit is T88P-. Don't recall the base part number.

Also, seals are positive type. Seal installer is also part of the original tool kit.

ps - don't forget to air-up the cylinder before, so the valve doesn't drop into the cylinder.

I used a $9 compressor from harbor freight designed for just such a task. Works like a charm.

Would the valve drop out of reach if the piston was up?
