Pulling away from the dieselizing crowd for a moment.

I think I might not put the Audi I5 diesel I have in the Syncro. No, I crave something a little less rare.

D24 owners, and I know you're out there, I need to know: How big is your engine?

Not the displacement, but physical external measurements. How long, wide, tall is that block? What's your bolt pattern?

What's the stick on the oil starvation issues in the head? Gasket failures and timing belt problems? Any fixes for these that you've come across?

I like the D24's torque @RPM value; If it fit I could regear the transmission and cruise at a lower RPM to save fuel. I'm not looking for a heavy hauler or a speed demon (Yet), but I do drive a wagon that's all wheel drive and i do use it to haul things in.

I imagine I would need an adapter plate to mate the engine and the trans together, but that doesn't bother me. I just need to know, before I go any further, "Will it physically fit?"

Hi, total lenght from front crank pulley to where the bell housing bolts onto the block is 27".

Bellhousing bolt pattern is the same as Audi.

Motor mounts are 10.5 " from clutch side of block compared to 6.25" on Audi. (driverside)

Oil pan is bigger, has wide bag near clutch end.

Flywheel is heavier, will take same size clutch plate as Audi, pilot bearing in crankshaft is bigger than Audi, but you could install a different bearing.

For the rest, the width and height are the same as Audi.

This engine has the same issues with headgaskets and oiling systems as the Audi diesels, but overall a good engine IMHO.

You could probably weld 2 oil pans together to make it fit in the Audi, but I think you will have a problem with the total lenght.

The turbo engine has lots of power but the N/A is slow.

Hope this was helpful.

So the bolt pattern is the same as the Audi I5 diesel? Sweeet, means it'll bolt right up.

I need to go out and measure how much total space I have in that engine bay; It's a Quantum Syncro and with the 5-cylinder in there I have a good amount of room up front...

I put a 5 banger TD into a syncro, there is VERY little room left behind the front valence, you will have to cut and rebuild the front valence farther out if you want to use the D24, the front bumper will likely have to be altered as well.

I went out and measured... I need about an inch and a half's worth of sheet metal work out of it.

I'm fairly certain I can do the modifications needed, I know some good welders and have access to wonderful things like sheet metal and brakes.

Probably going to need to modify a hood, too. Anyone have an idea where I can get a second hood, or should I start going junkyard crawling?

Okay, next big question, bound to start some kind of discussion:

What's the best service manual for these engines? Haynes? Bentley? Someone I don't know of yet?

AFAIK Bently does not make a manual that covers the D24.

Hi, here are some pictures that I have made from the Audi 5 TD and the Volvo 2.4 NA side by side, so you can compare actual size and differences between the two. ( The tranny is for a Vanagon Syncro and is different from your car tranny)

Hmmmmmm... looks marvelous from here!

Is that a D24, D24TD, or D24TIC engine there? (Doh! Didn't read the post, stupid. NA. Durrrrrrr~)

Looking to get rid of it? I'm (I will be?) in the market soon...

Definitely bigger, yeah, and are those the engine mounts all the way on the back? That big chunk of metal in the bottom right corner, in the fifth picture? Hopefully not, that would certainly not match up and be in the way of steering components...

And that is one clean Audi I5, just want you to know that.

Thanks.

It shows the motor mount and oil pan in the 5th picture, it is rather large and I don't think it will fit in your car. You could take two oil pans from a gasser engine, cut it and weld the two of them back together so that you get a longer pan. You also have to use the oil pickup tube from the gasser.

The cooling fan that is in picture 2 comes off and is in the same place that your front motor mount fits.

I have a turbo charger and exhaust manifold from a D24TD that I would like to install on this engine together with oil squirters etc when I rebuild it in the future.

Where is the oil pump on the Volvo engine?

itzdshtz · « **Reply #11 on:** September 02, 2006, 10:15:12 am »

The oil pump is mounted on the crankshaft end right behind the pulley.

Turbinepowered · « **Reply #12 on:** September 02, 2006, 07:26:21 pm »

So what manual would you recommend, Itz? For the D24, that is.

itzdshtz · « **Reply #13 on:** September 02, 2006, 09:16:21 pm »

Hi, try to get a Volvo manual, they seem to be a bit better than the Audi one. They list piston weights, valve seat insert sizes etc.

You could also buy the Bentley Audi 5000 manual, it is the same engine minus one cylinder. All the specs are the same as the D24.

Look at this website for some examples of the Volvo manual :http://volvoturbodiesel.blogspot.com/
