almost complete, but there are a few parts sold off it, namely the water pump, Crank sensor, starter motor alternator, air flow meter, What you see is what’s included.
it came out of a 1992 Sovereign 4.0, battery under bonnet version.
Average used condition for one of these. The engine has 135,000 miles on the clock. It was running and driving well before being removed. It’s been in storage a number of years.
Important note- valve stem seals are a common leak point on these engines. They dribble oil into the cylinders and can create some smoke at start up. Most of these engines do it at some point. When they run more often, this smoke can be very minimal, but when an engine has sat for an extended period, as this spare engine has, then it’s expected there will be some valve stem seal oil seepage into the cylinders which could create a lot of smoke on start up. Options are to either rebuild the head with new seals, or add some seal conditioner into the oil, to reduce any oil leaks.
It’s also possible there may be other minor oil leaks on this engine. At 30 years old, it’s not likely every seal will be completely tight. The outer corners of the head gasket are known to weep oil out onto the block (externally) on these engines too.
