Question Hydraulic lash adjuster help needed

Ok, so I have my '91 Legacy turbo engine sitting in pieces while I clean it. It's time to remove the valve lash adjusters, but I cannot figure out how to remove them. Then need to come out so I can soak them in oil, and make sure they are all still good.

Anyone know how to get these things out? It LOOKS like they should just pull out, but they won't budge.

Your '91 Legacy turbo is a 2.0L engine? If not, then you asked your question in the wrong forum - which might explain the lack of response. You might also consider buying the Haynes manual that covers the 91-98 Legacy.

I have the Haynes, and yes, it's a 2.0. The haynes manual says they come right out. That is, assuming it is referring to the same thing. Which is sometimes hit or miss, as it doesn't cover the EJ20 engine.

And I'm guessing the lack of response is because it's not a WRX performance question. Those usually get the most attention.

How to rebuild a 2.2
Quote:
The HLAs used in the 2.2L engine are very small in size. Compare them to the
size of the 1800cc and 2700cc HLAs. One advantage of these HLAs is the reduction
of reciprocating weight. The HLAs are installed in the rocker arms while the
1800cc /2700cc HLAs are installed in the cylinder head. The HLAs directly contact
the valve stem instead of contacting the rocker arm as in the 1800cc/2700cc engines.
The head gaskets are carbon composition with a metal hooked core. O-rings
are used to seal the oil passages. The entire gasket surface is silicone coated to
improve sealing characteristics during initial installation. This also eliminates the
need for re-torquing the cylinder head bolts after the engine has been operated.
The N/A cylinder head gaskets are interchangeable from side to side.
The turbo engine cylinder head gaskets have been modified to match the closed
deck design of the turbo crankcase. The gaskets are not interchangeable from side
to side or with the gaskets from the N/A engine.
The water ports have been repositioned to match the passages in the heads
and crankcase. The grommet area around the cylinder has been increased for
improved sealing.

But that doesn't tell me how to get them out of the heads.
