The A-series uses many L-series parts like the rod bolts and the valve stem seals. Yes. Now you know why the A-series is so bulletproof.

 

You can use:

* O-ring type (not recommended)

* Lip-seal type

* Umbrella type

 

The lip-seal type is different for A-series and L-series. This is the type that fits over the valve guide. It is the "normal" type for L20B, is the same as Chevy 4, Isuzu, KA, VG and L-series.

 

I personally like the Umbrella type, famous on the ford engines.

The "How to hot rod and race your Datsun" book says to use A series seals in your L motor if you have a high lift cam.They should work.

THANK YOU ... so if i have o ring type they wont work good? How do I tell what type I have? I have a series valve stem seals. wanting to install em on a l20b im freshening up...

To tell what type they are, remove them from the box. An o-ring looks like a little circular piece of rubber. That provides very minimal sealing and only works OK if the valve guides are brand new.
