Boxster engine advice needed.
Goal to build one good engine out of three 2.5 Boxster engines I have. Two had a cly. sleeve move down toward the crank. All IMS bearings good BTW. OK questions:
1. Prepping the one good block for new rings. Looks like air cooled Alusyls cly coating? Conventional honing? OR Use Scotch Brite pads buy hand, as we do w/Alusyls.
2. Was my pulling head studs out of bearing carrier, when torquing down heads in my first 2.5 head gasket replacement common? See above. Wondering if I need to go threw all the trouble of Time Serts? Never herd of anyone else having that happen to them. Factory head torque specks to high?? maybe? Sure seem like it to me.
