To car gurus,
My Subaru had a problem with the engine block and finally the engine seized. I have come across divergent views from mechanics, one mechanic wants me to just get an engine block and he'll do the repairs since he says not all components are bad in the seized engine. The other mech has advised me to just get a new complete engine and fit it to the car. In comparison the block is cheaper by around 30-40k but am thinking there could be hidden costs.
Am confused btn the two choices,
saidieni...


Get a complete engine.

My friend changed his for 110k (forester).

While at it make sure you understand why the engine seized so that you do not have to go through a similar experience.

In his case some dove parts were found inside the engine. There is mystery as to how they entered there.


Only two things can make the engine seize; lack of cooling water and lack of lubricating oil; nothing more nothing less!


Its a bit more complicated than that though basically it still comes down to cooling ... you may have proper levels of oil and water but after a long, hard drive, the engine should be left running to dissipate the heat, esp turbo ones. Most newbies dont know this, after the turbo charged unit rolls off the ship, they gun the car at max speed for 500km to Nairobi, switch it off and enter the pub to brag. A forgiving engine lets you do this a few times before the turbine and/or engine seizes. That is just one. Then there are sensors. ..mods with off-shelf turbos that develop more pressure than the engine specs allow. .....there is the radiator which comes with a plastic capping which usually cracks and loses coolant. ..etc etc


Thought all turbo-charged cars these days come fitted with turbo-timers to protect such drivers from themselves... Wrong?

I don't know @seppuku, the newer turbo charged subarus are a bit expensive, have never been nice and cozy with one...
Still, a 2000, 2500 or 3000 cc naturally aspirated Subaru will easily hit 180kph and keep going for hours, and these ones have no timers.

I am not a mechanic so wouldnt know whether he lied to me or not.

But this may change your thinking that only overheating can cause engine seizure.

The engine had a faint knocking sound which was diagnosed as a slow knock or something

Just replace the engine. seized engine has to be completely rebuild if the fundi didn't clearly identify the problem you will have to deal with a myriad of problems after the rebuild and you will pay more.

dove in the engine?Laughing out loudly Laughing out loudly Laughing out loudly and how was it running before ceasing? I think that was sludge that has almost solidified. if so then the cause is poor oil and adulterated fuel, and/or lack of proper servicing like not changing the oil filter or draining the sump completely
