Will the Ford L8 Duratec engine fit in a MX5 Mk3?

I need to replace the engine of my MX5 MK3 and I have been told that the Ford Duratec engines with the chain drive camshafts will fit. What I am mainly concerned about is whether the the gearbox bell housing bolt location holes are in the same place.
The reason I ask is that used Ford Duratec engines are a lot cheaper than used MX5 engines.

Thank you,

William Young

Experienced mechanics share their insights in answering this question :
Hi there. The Ford engine will not bolt up to your Mazda transmission, however, you can purchase a conversion plate that would allow the engine to bolt up to the transmission. If you do this, you will need to get a stepper plate for the flex plate that brings it closer to the transmission, change all of the engine mounts to a custom fit, and have to adjust the exhaust plumbing to adapt to a 1/2 inch change. I recommend finding a MX5 MK3 engine and replace it with yours. This will save you the trouble of customizing parts. If you need further assistance with your engine swap, then seek out a professional, such as one from Your Mechanic, to help you.

Would the Ford ka x reg engine fit an 08 Ford ka ??
ANSWER : Hello. It may be possible to swap those engines if the chassis are similar, the correct transmission and mounts are used, and all of the wiring and engine management components are swapped over. If the factory components do not work for the swap, then it may even be possible to have custom mounts made, however, it will probably be an expensive job. I would contact your local Ford dealership for details on whether or not the engines will swap easily. I would also inquire about what transmission, axles, mounts, and computer are needed for the swap to work.

I have a 96 Ford ranger with cel p0340 I have recently done a timing belt, engine runs great replaced cmp sensor cel still on
ANSWER : Hi There,
This may happen for a couple of reasons. First, check to be sure that the connections to the sensor are clean and not faulty or broken. Secondly, check to be sure you replaced the correct sensor as there are two camshaft position sensors in some applications.

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

I have a 2010 camry. I just recently replaced the engine with a 2014 camry engine. Now I have Four engine lights on. I replaced on
ANSWER : If you swapped the engine from a vehicle that is 4 years newer than the car is then you are going to have electrical and sensor incompatibilities that may not be able to be fixed by just a few sensor replacements. There were many changes in computer and emission related items between 2010 and 2014 engines. I would recommend having a mechanic like one from YourMechanic come to you and compare the two engines to isolate the possible differences and see if the problem can be fixed.

Engine malfunction light, reduced engine power, engine powered down
ANSWER : Hi there. There are a lot of things that can cause this on your 2012 BMW M5. I usually start by scanning the computer for codes to see what comes up. If there are not codes then I load test the alternator and the battery to see if they are failing. Low voltage in the electrical system will cause this. If that is fine, then it is usually caused by a failing throttle body. I have seen a lot of these fail due to the motors in them hanging up. If the problem is only happening intermittently, this can make the issue hard to duplicate, but you can still have tests done on the car. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to test the vehicle and diagnose the Engine Malfunction Light.

How do you replace the rear & side engine mounts without lifting out the engine? & how do you lift the engine out?
ANSWER : Hi…thank you for your questions. If required in the application, a portable engine support bar is used to support an engine during mount replacement. The support bar has lifting capability as well so that the mount can be unloaded and removed. If a particular repair application requires a "crane" (complete engine removal for instance), such are portable these days in any event. With regard to the exhaust system repair, mechanics use ramps to gain access. Six ton portable jack stands will safely support a car two feet into the air which provides more than enough access to repair or replace any exhaust system component. If you desire replacement of the mounts, please refer to YourMechanic’s motor mount replacement service page. For exhaust leaks, please use the exhaust system inspection/repair page page. Once on each of those service pages, if you click on "Get a Quote" and enter your vehicle information (year, make, model) you can obtain cost info and schedule the service. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.
