Punto (Mk2/2b) Damaged Cylinder Bore!

[MarkM83]

I've just bought a 2001 Punto with only 47,000 miles on the clock for £100! It had a lumpy idle, tried a few things such as cleaning injectors and change spark plugs but no better! Did a block test and went immediately green so whipped head off this morning hoping cylinder head gasket had gone! No
obvious signs of gasket failure but found something even worse!!!! No 1 cylinder has had debris flying around which has scored the bore and damaged piston crown to the point where there is a small hole! Account for the blue smoke on start up and lumpy idle!
My question is if I buy another engine and fit it will I get Engine Management Lights on galore? I know I bought this car cheap but spending £150 or so on another engine the budget is getting tight on whether the car is actually worth the time and expense?
Any suggestions on how much a headache changing engines over would be appreciated before I buy one?

Car for hundred quid at that mileage, you must be mad someone sell you a fault engine or a fake mileage. I think buy other perfect condition car would be a lot better than fit a new engine in it.
I am not risk to tell if the engine management lights will come on because ECU was register the exactly same engine code if swap mind have different code to confuse the ECU.
That what is happen to my very first car Ford Fiesta 1.25 engine failed cylinder rod crack and swap the engine was much cheap then cost of rod but the light come on everywhere was hard job and very waste my time and the money
It is not worth swap unless if it was a old non-electric engine

U need to keep original cars engine ecu with the car


Dont use the donor ecu as it will never unlock the immboliser


The biggest ball ache is getting all wires to sit right in place for reconnection

I did put a 2nd hand engine in mine, it took a little crank longer on its forst start up and missed but the ecu will quickly adapt, itd need a few drive cycles and it shud be good as new so to say

If u have mes full version, u can run the phlonic wheel relearn, this requires a throttle procedure but itd allow engine and ecu learn each other no problems

Cheers for your replies. What I can't understand is how a block test on the water showed head gasket problems? When I took the water header tank cap off water poured out of the filler neck? This to me said that the combustion chamber was blowing past head gasket pressurising the water?
Not sure whether or not just to put this engine back together obviously with a new head gasket even with the score on the cylinder wall and see how much life I can get out of this engine before swapping it anyhow?
