[Guest archemitis]

i guess tsb 02-88-93 has some info i would like to get, but i cant find anything about it anywhere. its about the cracks between valves in ea82s. if i show any machinist my cracked head, he laughs and says get a new one. but supposedly sometimes it ok. somebody help me out here.

Beyond paying http://www.alldata.com $25/year for access to the TSB's for one specifc car, I'm not sure. Got any buddies at a Subaru dealership? I only see that TSB listed for the '89+ cars. The Loyale is listed in 1989 for some reason.

I have service bulletin books 1, 6, and 8. But they only go to 1985.

 

Sorry, Qman

The aftermarket service manual, on CD, I have came with the service bulletins I went and posted a PDF of the one in question here.

 

<a href="http://home.attbi.com/~c.moe/EA82head.pdf" target="top">home.attbi.com/~c.moe/EA82head.pdf</a>

 

It's not exactly the same as the one from Subaru, the information is a direct quote, the graphic is the same, it just dose not have the offical Subaru letterhead.

Craig, thank you very much here is what his pdf file says

TECHNICAL SERVICE BULLETIN

CYLINDER HEAD CRACK BETWEEN THE VALVE SEATS

Model Subaru L-Series & Loyale (1.8L MPI & SPI OHC Engines)

Group Engine

Bulletin No. 02-88-93

Date February 5, 1993

NOTE: Do not replace cylinder heads for a crack between the intake

valve seats.

Some cylinder heads may exhibit cracks between the intake and

exhaust valve seats. These "bridge cracks" do not cause coolant

leaks or result in valve seat movement. "Bridge cracks" are cosmetic

in nature, and do not justify replacement of the cylinder head. See

Fig. 1.

Production Changes to Prevent Bridge Cracking

1. A chamfer was made between the valve seats and the cylinder

head.

2. Distance between the intake and exhaust valves was increased.

This condition does not affect the integrity or durability of the

cylinder head nor the operation of the engine.

Craig,

Did you get those CD manuals off E-bay?

Thats were I got mine. 6 disc Import set for $44.95 shipped. Smoki'n good deal!

[Guest GlCraigGT]

I only got 2 of the disks for roughly the same price:mad: but that's how ebay works. I am disapointed in a couple of items with it. There is nothing on transmissions execpt how to change the oil and no photos, just some drawings.

thanks alot, i have been trying to find that for about a week. im sure its somewhere in the archives, but i couldnt find it. this could save alot of people $400, because the second a machinist sees that crack he says its shot. thanks again. these discs sound interesting, better than a chiltons, i bet.
