About to pull the engine out of a ‘97 LX450 for a rebuild. Other than the usual suspects (pumps, hoses, seals, belts etc.), what are some things that I will have access to in the engine bay that I should check and replace or rebuild? Anything notorious for needing attention? PHH already done. Already planning to pull the rear heater and bypass. Gonna do the Slee dual battery washer bottle move while it is out. Firewall seals?
