Are ea82t heads different from ea82 heads?

Recommended Posts

Found a MINT '89 gl-10 ea82t, guy said head gasket was blown. tore engine apart, found tiny cracks in between the valve seats. is this terribly bad? should i replace them? And if so, where can i find refurb heads?

Cracks between the valves are very common and are to be expected/ignored. Subaru refers to them as "bridging cracks". But do look for a crack up in the port runner. A crack there and time for another head. The heads used on the XT and any model with a turbo are the same. Engine has to be the MPFI type.

Just check the back of the passenger-side head. The holes used to mount the turbo should be there, just not threaded. Also the provision for the turbo oil-return line should be there but will need drilled.

Keep in mind, that while Subaru was building EA82 Turbos, they phased through 3 generation of EA82T head designs. If you are looking to replace your heads, you might do good by looking through the junkyards and see if you can find a new(er) EA82T Motor with Gen3 heads on it.
