Clean everything and use new gaskets everywhere and avoid using gasket goo for a gasket, combining both is always better :yes:
If it's a bigport 4age, i have a set of standard acl forged rod bearings you can have for $50 :P assuming the crank isn't fooked and needs a slight grind...... Other than that thrown new everything at it, i.e bearings, piston rings, get the injectors cleaned, polish the cam covers, polish the fuel rail, the list doesn't end............
