What is the left? What is the right?

Facing the direction of your car... Aka Left is drivers side, Right is passenger side (in the US) or any left drive countries.

 

Miuras are especially confusing because of the transverse arrangement.

Lamborghini used more than one scheme for cylinder numbering depending on model.

 

I believe this is correct... I will allow anyone to chime in her - but for the modern cars, yes I believe your are correct.

Try this....sit in the driver's seat. The left bank is on the left, the right bank is to your right.

 

Many people get confused because the left/right intake manifolds are on the opposite side. This pic should explain it

As they say, a picture is worth a thousand words.

An important thing to remember is that Murci and Diablo engines are, in a way, installed "backwards".

 

Now I am all confused. I'll look for some documentation. Technically, the left bank is on the US passenger side.

 

On page 18 of 2003 US/Canada Murci manual: "Cylinder No. 1 is the first one on the left looking at the engine from the flywheel side." Therefore it looks like Lambo does indeed reference sides from looking at the car from the front of the car, as correctly labeled in Jay's picture.

 

That's correct. Look at the intake tubes. They're facing diagonally down towards the cylinder bank on the opposite side.

US Passenger. Per the pic

Thanks for the confirmation Mike.

 

This is just one of the glaring reasons why Italy (in spite of the wonderful things they have created) is no longer a World Power.

Right is Left

Left is Right

I'm not sure what they were thinking with this logic.

The argument that the engine is in "backwards" (flywheel in front, timing chains in back) would be plausible EXCEPT that the Countach had an identical drivetrain layout and called the right the right and the left the left and started numbering the cylinders from the left rear.

What is really important is firing order and which cylinder is #1, #2, #3 and so forth. and of course which direction the crankshaft turns, OOPS! For some reason the Diablo turns the other way, go figure. You simply can't tell the players without a program.

If this was a British car the sides would be referred to as "Near Side" and "Off Side" whatever the heck that means.

Dear Lamborghinisti,

Wow, you really do learn something new everyday. I thought the right bank ( Diablo ) was the passenger side. That's the way Ferrari refers to it. ....sitting in the driver seat.

Sooooooo.... I guess a check engine light L is on the passenger side of a US car & and a check engine light R is on the driver side of a US car

Freeeze...Miami Vice !

 

That picture is WRONG. An "L" check engine light is the drivers side, "R" is passenger side. Just like you would assume. It's NOT backwards I just confirmed this having an "L" check engine light and an orange glowing cat on the drivers side I used that damn picture as truth and ended up replacing all my O2 sensors to find out.

 

The picture is correct. Here are the words right out of the Diablo workshop manual.

"The engine cylinder banks are defined as right and left hand as seen from the flywheel.

The No. 1 cylinder is the first of the left hand cylinder bank near the flywheel, the numbering continues following a U towards the right hand cylinder bank."

The flywheel is in the front so you are viewing from front looking toward the back. The right hand cylinder bank is on the left side of the car.

There is an accompanying illustration but I'm having trouble with my scanner right now so it will have to wait.

That apparently the check engine lights are inconsistent with this comes as no surprise.

 

Well I'm speaking from actual experience, I've wasted allot of hours over this. Luigi must have had a good chuckle when he hooked up mine.

 

It would be virtually impossible for this to be switched since the harness is not symmetrical. When you first turn on the ignition key, do you get both CEL and both cat lights lit ie are all four indicators working?

All four lights work. But they are not all on all the time. When the catalyst lights come on it's only for a moment with beeping then they go out. The CEL's stay on, but not now because I know which is which, and have replace the correct ones.

 

Perhaps the reason they changed this on the later cars...Gallardo (and I believe Murci) have CEL 1-5 and CEL 6-10...And #1 is as you say, left hand side when viewed from the flywheel Kind of takes the confusion out of it.
