I have an issue on my engine which maybe can be resolved with ("only") a head gasket replacement (see details here).
An alternative to repairing the engine may be to replace it (I found an engine for a model at least similar to mine, if not the same; the engine is sligthly different from mine but might be the more powerful option that was proposed for the same model) for what seems to me to be a cheap price for an engine (400€).
Now I don't have enough money to buy it nor do I know for sure it would fit, but since I cannot know for sure that a head gasket replacement alone will repair my engine and that repair anyways would cost a lot of time, I'd like to know whether or not to try to pursue this alternative a bit further.
My main questions (before knowing if it would fit) are twofold:
Is it easier / does it cost less time for a qualified professional to install a new engine instead of trying to repair the current engine?
Which one is likely to last the longest: An engine sold as being 180,000km "old" (which would mean 34% younger than the one installed) or the current 270,000km old engine with a new head gasket? I am a noob when it comes to car mechanics so I don't know if there's parts other than the head gasket that are very likely to fail with time.
YOUNGER ENGINE DETAILS:
- 122HP (vs 82HP for mine)
- 180,000km (sold as such at least)
- Sold without injectors
- Price: 400€ without gearbox or 600€ with gearbox.
