I reckon I can see the flying lead connector below the inlet to the manifold but that's about it. Anyone know where it attaches to the engine and what needs to come out to replace it? Oh it's a late 90 degree engine.

1999? You mean a late 60 degree engine?

The engine sits straight up and down in the engine bay. That's a 90 degree is it not.

It is, but has no relevence to the 'v' angle. The 60 degree or 90 degree is the inside angle that one bank of 3 cylinders make with the other bank of 3 when viewed from either end.

...... and the one in your photo is a 60 degree engine (type ES9J4).

Sorry I can't help with the location of the speed sensor.

The PRV V6, 90degrees with 12v looks like this:

...like this:

And the PRV 24v 90degrees, looks like that:

There is NO external difference between the 24v and 12v 90 deg units, as study by me has found that the original 12v design had left PLEANTY of room for an extra set of valves in the current space to make 24v!! Hence them looking identical with just the additiion of 24v on the rocker covers, they too being interchangable

Albiet with a single cam, but they do the job perfectly!

Were did you get the 24v pictutre from, do you know of the car and its Registraion??

Hi citroenxm,

I'm not sure what u mean but, I think I cannot agree with you, if we speak of appearence. Those photos are from ebay cars and I've seen them (12 and 24vs) many-many times the last years. As u open the bonnet, they *do* look different, as per the photos. My 12v looks like the photo 12v. Doesn't your 24v look like the 24v in photo?

When I first saw a 24v engine photo I was surprised how little care they took of the "looks" of the top of the engine, having previously seen the good aestehtical result of the 12v cap (even my BMW-obsessed friend appreciated it). Their caps are different. Looks like they designed the 24v in 5 minutes

Now, technically, I have no info except that indeed the 24v is a single-cam engine, and, also, I have the impression one bank of valves (inlet?) uses 1 rocker per valve while the other bank (exhaust?) uses 1 rocker for each 2 valves. On top of this, the inlet manifolds are totally different as u prob. know, technically and aesthetically as well.

George

Jorgy9,

I have a spare 24v engine, will have to remove the cover to see what drives what.

As for Rocker covers they are completely interchangeable!

The only difference between the 12 and 24 v 90 deg IS the design of the inlet manifolds...

The 12v has a single inlet throttle body were as the 24v has twin throttle bodys..

I wouldn't be AT ALL surprised if the manifolds were interchangeable... which gives me an idea...

I wonder if my spre 24v inlet manifold WILL fit one of my 12v engines to fit back into my Green K reg 12v... Hmmmm not that sounds interesting.
