I cant seem to get the cyl. heads off of my spare ea81

I dont want to hurt the heads but its stuck in place

Cant get rocker assembly hard ware off but head bolts are out

Rods are able to wiggle around

tried some different solvents but no go

What gives?


Any suggestions to safely remove the heads

Put the spark plugs in an roll it over by hand, just make sure you have 2 helpers to catch em or just thread the head bolts back in a bit

Look 3 more times for hidden or missed fasteners ;) The head may also be glued to the studs with rusty corrosion type stuff. Try flipping the block up on it's side (studs up) and soak each stud area with LOTS of Deep Creep, or PB Blaster or something. Be careful and patient if it's a good engine.
