Reconditioning, Refurbishing, Remanufacturing Or Rebuilding?


Lowest form of repair. Quick and cheap to get the motor running again.
Not a long term reliable repair, if a repair at all.

...disassembly and the replacement of worn parts with new or in spec parts.

I'm not about to tell you how to recondition an engine, I'm not a mechanic and I don't have the
time to learn how to do this properly to teach you lot. Personally, I think if you want something
doing right and you don't know how to do it, pay someone who does know to do it for you.

Why bother taking all that time and effort? Remember, time is money.
What guarantee do you have that your repair will last!
You might save a few hundred quid but it could be false economy.

Can You Recommend Anyone?




Do it yourself, there is no skill involved. Just take it apart, clean it and put it back together.
 Don't expect the fix to last very long, if at all. Not a service you'd want to pay for.

Can I have A Banner Here?

Yeah, contact me and let's discuss money and previous happy customers.

If the above companies can't help you then find a qualified rebuilder

Any Companies I Should Avoid?

NEVER use also known as:
Heathrow Engines
Heathrow Motor Services
Bray Engineering Repair Centre
Engines Direct
Brentsouth TradingEngine Warehouse
MPH Engineering Ltd

Why So Many Names?

Because Trading Standards are always on them and they have appeared on Watchdog.
As 1 of their company names gets bad reputation they will change the name of the company.

They quote low prices with a ridiculously high 5 year/60K mile warranty.
However, if you
search the internet you will find a lot of very unhappy customers.
They tend to find a lot wrong with the engine which bumps the price up and if you don't
pay it, you then have to pick a car up with a stripped down engine. They also charge
storage for the time the car is sitting there in pieces waiting to be collected.
