Engine replacement/repair?

Good day,

I drive a 2003 2.0l Pajero IO with the 4G94 engine.

Last week I was driving on the highway and suddenly heard a weird noise, almost sounded like car misfiring. As I pulled over, I saw smoke rising from the bonnet and  oil leaking out from the bottom in great amounts. It seems the main seal had popped and that the car has lost compression. I stay in SA so sometimes finding spares at times can be timely/tricky.

My mechanic is looking at finding out from engine importers if the engine is available and if parts are available (although most places are still closed due to the holidays so this might take time)

What I would like to ask from the forum:

1. Are there any other engines that it can be replaced with that might give a bit more power/ better fuel efficiency?

2.  Any guys from South Africa here that know of an engine that is for sale?

3. Any other advice/suggestions of the way forward?

Will appreciate any advice :)

Not the best start to my new year

Engines for Africa has an

Engines for Africa has an 4G94 GDI engine for R7950. I currently have 4g94 MPI engine. Will I need any mods to put the GDI engine in or is it just plug and play?

Definitely NOT plug and play.

I haven't looked at the 4G94 specifically, but I have explored swapping out a 4G93 GDI and replacing it with an MPI 4G93 - you're going to need the entire "front cut" to make it happen.

You'll need the complete engine with pretty much all the accessories, intake plumbing etc, the ECU and the wiring harness, throttle pedal, with ECU (yes it has it's own ECU) and wiring and this is not a complete listing.

One last thing - I'd say you're better off with the MPI engine - the GDI engines have their own problems, and MPI is better understood and easier to source spares for.

will search for MPI then :)

Thank you Fordem, I found another MPI engine from a scrapyard apparently in 'fit and start' condition or R12k. Is this a decent price?

First - I have no idea what value R12K translates to...

and second - what would be considered "a decent price" is going to vary from one country to another.

Consider the following questions ...

----------------

What condition was the original engine in immediately prior to the failure?

What would it cost to repair the original engine?

What condition is the replacement engine in - fit & start means nothing to me - I fit it, it starts, it runs - but - how well does it run - is it burning oil - is it down on power - was the timing belt ever changed - is it sludged up?

What condition is the rest of the vehicle in?

What would it cost to replace the vehicle with something of similar utility in a condition similar to what you had immediately prior to the failure?

---------------

Personally I'd rather repair/rebuild an engine than replace with a used engine of unknown condition - the idea being that at the end of the day, I know I have something reliable that I can trust to take me to my destination and bring me back.

I mentioned in an earlier post that I had considered swapping an MPI engine into my car - the plan was to buy a crashed vehicle, pull the engine, rebuild it, and then swap it over - I abandoned the idea on discovering that the MPI engine had hydrolocked when the accident occured and had possible crankshaft damage - the GDI engine I have now runs reasonably well, but burns oil, and more importantly, is very difficult to source parts for - a high pressure fuel pump, if I needed one, would cost me more than the car is worth.

Hi Fordem, Valid points you

Hi Fordem,

Valid points you raised - thanks for all the info.

The engine did before the incident consume some water and leak some oil. In April 2017 a gasket went that caused the water to leak out at a very high rate.

so the engine was not perfect condition before the incident. It is also hard to tell what the extent of the damage is - the mechanic first wants to get an idea of part availability and price before we start opening it up.
