    Rover V8 Stalling, then only running for a few seconds....help...

    Hi all

    The 3.5 Rover in my Capri is playing up royally and I'm completely stumped.

    It had some intermittent stalling a while ago, but I put that down to a loose battery connection (now fixed).

    Took it for it's first proper run to a meet last Sunday.

    It ran great.

    Fired it up during the meet and it idled nicely for a couple of minutes, then just stalled.

    After that, it would start and die instantly. With a bit of throttle, it would stay running, but seemed really lumpy and misfiring. Stalled at every junction and just cut out even when driving (on A roads)....but sometimes just picked back up when moving... which was pretty terrifying.

    I'm just completely stumped.

    It's running a two barrel Solex. I was hoping it was the coil, so popped a spare one in today, with no joy.

    Before the meet on Sunday, I had tried to improve the crankcase breathing on it and had tied the rocker cover breathers into the inlet manifold. That was the only change I'd made before the meet on Sunday and I've now removed the piping and just returned them to venting to atmosphere. I can't see how that would cause the running problems, especially as it's all back to how it was before.

    I have no idea where to go with this now.....Can anyone help at all?

    I know this sounds stupid, but I'm not really sure...... it has a normal rotor, but then an odd white plastic section under it, which seems to block the view. I'm inclined to say standard points. Certainly doesn't look like an aftermarket electronic kit has been added, but I don't know what the normal standard Rover ones are like.

    I'll try to post some photos up tomorrow morning.

    I'm terrible with Rover V8s!

    "tied the rocker cover breathers into the inlet manifold"
    Introducing air between the carb and engine, leaning out the mixture. Causing the stalling.
    Just a theory!

    I thought something similar, but I'd had it set up like that for a really good run and it was working great.... Then all the problems started. The reason I did it in the first place is because I'd read about the RV8s liking the crank case under negative pressure, but I'd always suspected the idea of introducing additional air into the intake after the carb.

    I've now put it all back to open venting and blanked off the manifold stab-in, but the problem is still there.

    I know almost nothing of rover v8's but I think they have an ignition module (white box in dizzy?) that can be troublesome?

    I'd been thinking about the ignition module as well. It does seem to crop up a lot on forums. I'd replace it, but I don't know how, or which one to get.

    I've got an inline fuel filter, so I'd have thought the jets would be OK. Might take a look at them anyway, just in case. It's my first solex as well, so I have no idea where the jets are. I'll have to have a look for drawings. Would jets cause the random stalling?

    It's possible but unlikely, blocked jets would make it run badly all the time, but could certainly cause stalling.
    I'd look into the ign module - I think its a simple unplug & replace job though.
    Look on Rover v8 forums for help maybe?

    3 links which might help;

    I have a feeling mine has the ignition module inside the distributor. Does that make it "opus" type? No idea if that type can be changed. I'll have another scout through the various forums.
