4 Things You Must Consider Before Engine Overhauling

Engine Overhauling can be a tough decision to make. But at times, engine overhauling is the only option you will be left with. Engine Overhauling is a quite costly procedure but it is still economical when compared to the price of new car. With reference to one of my previous articles Here’s What You Need to Know About Engine Overhauling”, I would like to discuss few aspects of an overhauled engine.

The result depends on the Mechanic:

When it comes to engine overhauling of modern cars, 80% of the after-haul result depends on the competence of the mechanic. If your mechanic is an amateur, the result of engine overhaul will likely not be reliable at any cost. Getting your engine overhauled from an untrained mechanic will surely surface issues with assembling and integration of different engine components.

Engine Parts:

Once the factory stocked parts are replaced by after-market parts, the engine performance and quality do not remain the same. The after-market parts will wear off quite earlier as compared to the factory stocked parts. Moreover, for imported cars: engine parts available in Bilal Gunj Lahore are mostly secondhand. So of course, there would be a difference of tolerance and performance after your engine is overhauled.

After-hauling Costs:

Rebuilt Engine usually does not work ideally as factory stocked engines do. Even if you get your engine overhauled from the most professional mechanic in town, you may still end up facing problems in its assembling, integration, and compatibility of parts. Running after mechanics and paying regular bills at the workshop can be very annoying especially if you have a day job. As it turns out overhauling cannot just turn out to be a monetary detriment but it may also cost you lots of hours at workshops.

No Warranty:

Parts used for overhauling engines in Pakistan are generally purchased from Scrap Market i.e. Bilal Gunj Lahore. Therefore, even after spending thousands of bucks on your engine, you will only be given a check warranty and nothing else. However, dealerships may offer you a warranty for a few thousand miles but with the additional cost that may be equal to the cost of the new engine (from the scrap market).
Have you ever got your engine swapped or rebuilt? What issues did you come across after overhauling? Share your experience in the comments below.

    Never had engine swapped but had gaskets replaced on 2 different cars from 2 different mechanics. Totally dissatisfied both times. Faced compression loss, slightly irregular idle and unreliable starting. Sold both cars not long after gaskets changed. Mechanics, parts and workmanship in Pakistan is not at all satisfactory.

    Had a Daewoo Racer (Taxi scheme) in 2003. Blew gasket, replaced it. Suffered irregular compression loss while driving. Sold it and bought 0 meter Mehran.

    Sold Mehran after a few years and got Civic 95. Drove it for 6 years, replaced gasket and got irregular idle. Sold it in 2012 and bought City 2013. All problems caused by less than competent mechanics and parts.

  3. Just overhauled Mehran 2004 engine with maximum part change caz i was having smoke , engine oil burning in 2 months and mileage performance issues due to engine overheated on moterway:

    However Here are the problems after overhaul:
    Milage as compare to earlier days before my mehran engine worn out, is still bad i mean very bad... earlier by cng i can drive 25-30 km and now 16-17 only i was told that it will take some more time but it was also told that piston size in market is bigger than original so there will always be a problem.??? although i just drive 1000 km ..so let see.
    Water is dryingout or perhaps leaking and i have to refil after 4-5 days the reserviour only.. mechanic is unable to solve it...
    Speed is limited to 100 max on cng where as earlier it can easily go to 120 on cng. I m told that it is due to poor cng availability... lets see after few more 1000 miles what will hapen....
    took almost 1-2 weeks in back and forth visits to workshop... literly my office suffered alot for 2 weeks. one issue..then other issue.. to be resolved (oh yes i also got fixed my head lights , gear box, breaks, tyre, suspension,denting painting) that might have caused such time) but 1 week is definite disturbance)
    Cost of engine over haul and subsequent oil changes and fault corrections:
    35000 over haul thereafter 3000 to 5000 extra for after running and minor issues.. like coolant loss from radiator..

    I thought of replacing 2nd hand engine but afraid that 2nd hand engine might also need over hauling then what????

    My final words
    if you can spend extra do go for better 2nd hand mehran preferably euro version with good engine (or any vehicle) and keep an eye on radiator leakage my ignorance of just Rs. 200 repair work of radiator ended up me complete engine overhaul..... After 3-5 years do service radiator
