A quick question to you techies.

Is the 2.5 TD engine in an Omega, fitted with an automatic gearbox, exactly the same as one fitted with a Manual gearbox i.e. will an engine taken from an auto fit into a manual car - presumably the bell-housing etc. is exactly the same, but will obviously need the flywheel changing etc. Can someone confirm this is correct?

Cheers

As far as I know the basic engines are the same. You will also need a spigot bearing for the crank, the autos dont use them.

Excuse my ignorance, what do you mean by 'spigot bearing' - is this the clutch release bearing?

[Matchless]

There is a small bearing in the end of the crankshaft, the gearbox input shaft passes right through the clutch and is supported by this bearing.

What's involved in fitting a Spigot bearing, are they difficult to do?

[Matchless]

If you are lucky your auto engine will already have one, its not used with an auto box but some seem to have it fitted anyway. If not then it just taps in with a socket or piece of tube as the drift, be sure to only apply force to the outer sleeve though, they are quite delicate.

I think that you will also require all the other extras like a pedal box, clutch switch if fitted with cruise and tech 2 to tell the ecu that it is now a manual. Apparently not a quick or easy job mate.

Thanks for the info - it's really appreciated!

Think you're mis-understanding..... I'm not converting my car from an Auto to a Manual. I'm replacing the engine in my car (which is a manual) with a second hand engine - mint with only 38,000 miles, from a late car with rear accident damage - that is fitted with an Auto.

I now have the engine and can see they are the same!

Engines are basically the same but you will need to remove all the bits that turn it into an auto and replace it with those that make it a manual, not least of which is a dual mass flywheel.  

If you already have a broken manual engine, then you already have the required parts?

What happened to the old one......was it excessive bore wear it did it do the ow to common rod throwing trick.

You're right.  Really must pay more attention.

A long story..... you may recall that I have posted on here before about a ticking / tapping noise on my engine that's been there for a while and slowly getting worse. Well, I never got to the bottom of what the cause was and my dad (who is in the trade and has his own garage) agreed to take the engine out and strip it as he too was unsure of the cause of the noise.

Anyway, once out and after speaking with the original owner of the car I became aware that the original engine had already been replaced due to pump problems, which were then subsequently incorrectly repaired and resulted in the engine been written off. As a result the previous owner had a replacement engine fitted from a much earlier car in desperation to keep costs down that had done 200K plus miles. Upon close inspection after stripping we found the cause of the noise to be excessively worn valve guides and were going to recondition the whole engine. However, we also found the casing of the block to have an engine mounting lug broken. So because of that, and the cost of overhauling we decided to source a replacement engine which ended up coming from a 2000 'W' with only 38,000 - I saw the car it came from and the mileage seemed genuine - but which was auto and hence the purpose of this thread.

I must say the engine which we took out that has covered over 200K was actually in remarkably good condition on the bottom end with minimal bore wear to say it has done this mileage. The overall reason I decided to get the engine stripped was because we thought the cause of the noise may have been the timing chain and I didn't not want to risk a big blow up a long way from home - the car is now covering more miles than it used to since I've had it.

The replacement engine is now in and sounds sweet (for a diesel) so I am back on the road! I still reckon these are not a bad car - not as powerful and hence down on performance compared to the V6's, but more refined and better than some of the 4's. To me, a good balance between economy (35 - 45mpg dependant on type of driving) and relaxed driving. In terms of performance I'm not really too fused because I also have a Subaru Impreza with over 300bhp that I use at the weekends which even the V6 Omegas would get nowhere near - but this is certainly not as smooth and relaxing to drive - but is an absolute joy when in the right mood in a totally different kind of way.
