Ford coilpack failing?sowen

It leans off very suddenly, trying to rev out of it didn't work on the few occasions where it's still been able to rev. I think the air temps have been ranging from 25 to 40 degrees when the loss of power has occurred, will double check the readings the next time I get an opportunity.
The ignition has to be turned off to restart on the P6, to be honest I've not tried an instant restart before it powers off (I can beat the powering off on the key, still in early stages of testing to have consciously tried it yet). The electrical noise could be a likely cause, something to consider if it happens again.
I have just swapped the coilpack with another known good unit, no issues yet but it's too early to tell....

Got a little problem with my Rover P6, it's running newly installed Megasquirt with Ford EDIS4 doing the sparky stuff. Over the past few days after leaving the engine idling to get it upto temperature there's been an intermittent roughness and loss of power causing the engine to die. It's hard to tell if it's an ignition misfire or not, spraying water onto the exhaust primaries when it's in the process of not wanting to run doesn't show an obvious colder cylinder.
It has a wideband lambda fitted and that goes off the scale lean when the loss of power happens, sometimes the engine will slowly rev up and others full throttle doesn't do anything as it's about to stall. I've even plumbed a pressure gauge into the fuel rail feed and it reads 40psi when running. Watching my laptop with TunerStudio running I can't see anything obvious on the fuel side to cause it to run badly. I've got a new set of spark plugs I'm about to try out later. The car hasn't got an mot so I can't take it out for a blast either. It was only doing it when at running temperature hot, but I've just moved the cars round and it did it again, loss of power and stalled.
Now the odd thing is turning the ignition off and restarting fixes it? This is making me wonder if I've somehow broken the coilpack and it's imminently about to fail permanently. Anyone have any thoughts?

Glad it's not just me then. Frustrating when I try to scroll down and the page goes white and hangs. Being logged in it's not as bad, and the Reader's Rides section is probably the worst for it.

Is it just me or is RR really slow to load and scroll?
This last week it's started to sometimes not load the sub-forums. Re-loading the main menu and trying again it eventually gets through. Sometimes it just won't scroll, like my computer has crashed, but it doesn't happen on any other sites/forums, just RR?
I'm on Windows XP and Google Chrome if that helps.

Best car on here . I would love to see a video of it being spanked up the road ..... Thanks , so do I, will have to wait and see what comes in the next year or two.... Nicely wrapped Megasquirt efi loom, looks the part and should last as long as I could want it to Boost pipes from the air filter relocated to the top, hoping there will be less heatsoak compared to where they were underneath the turbo before Testing the linelock in the garage Parked outside beside my other toy

Finishing off the Megasquirt install on my P6 and give it a pre-mot checkover, hoping to book for early next week

Have a read of this, it's from a guy on another forum I frequent. This is an A6 3.0TDI V6 that had engine management problems that he's converted to run a Bosch VE pump with no engine management at all! 306oc.co.uk/forum/showthread.php?tid=8107Makes me want to brush off my two spare Bosch VE pumps and find a V8 to put underneath them

Rover V8 onto a FWD Gearbox?sowen

There was an Audi V8 on an Audi transaxle fitted to an MR2, it may have required significant chopping to fit however!
To me the question is where do you want the engine, transverse, longitudinal, rear or mid mounted? Ultimately, there is no fwd Rover V8 transmission available without custom fabrication.
Have you considered a small yank V8 on fwd transmission?

There was the Oldsmobile V8 from the late 70's to early 80's, based on a beefed up petrol V8, and apparently very very unreliable. I think Perkins began development of a small V8 diesel based on the Rover V8, that project was cancelled and became the 4.2 and crossbolt variants. Alternatively, I've read of references to mounting mechanical injection pumps on more modern common rail type diesels, I've no other information or details of those. yeah I think a mechanical injection pump on a modern engine maybe the way forward, I don't want the hassle of all the electrics! unless anyone knows of a simple setup on a modern engine the audi v6 is promising but probably complicated to fit in another car? not after a big heavy lump just don't have the room. thanks guys for the input. I think the obvious car-based V6/8 diesel lumps are Audi, Mercedes and Jaguar/Land Rover. All will have fairly well integrated ecu's and looms, maybe possible to get running standalone, but costs would obviously be an issue. If it were possible to find a suitable 8 cylinder IP off a truck, or a pair of matched 4 cylinder IP's, mount and time them, pipe them in with suitable injectors assuming the combustion chambers are suitable then it could be a viable project. Not that I haven't been pondering this myself in the past Any chance of a clue as to what the plans are?

Good plan on the Jaguar front subframe, have you considered fitting the rear irs off a Jaguar too? They come with a nice selection of ratios and with optional lsd's

Getting the Vitesse mot'd before the efi conversion is just too sensible I really hope you get it done in time, took me less than a week from receiving my Megasquirt ecu and loom kit to getting the engine running with previous experience and all the leftovers to hand...

An egt can be something to research later on, I just happen to have a spare engine kicking about with an egt probe in the exhaust, not sure if it's possible to salvage that or not?

Because I'm now going efi the 15psi fuel pressure gauge in the dashboard was redundant giving me space for the pressure gauge. Monitoring exhaust pressure is more of a high end diesel tuning thing, but the curiosity is there on my homemade lash-up of parts! I'm going to assume that it would give some form of indication of when the T25 becomes a restriction and it's time to consider a T28 or equivalent?

Silicone sealer (I'm not sure on the makeup of Tigerseal) kills Lambda sensors in very short order.. Curious about the desire/need for an exhaust pressure gauge - and how did you decide a 30psi gauge is about right? I've never heard of silicone killing lambda sensors, though they can be sensitive so it really wouldn't suprise me. Looks like the exhaust paste is beginning to win now The reason for the exhaust pressure gauge apart from having a spare gauge and hole in the dashboard is that the engine is 10.2:1CR using homemade and scrapyard parts with a small Garrett T25 turbo. With the Megasquirt I can in theory start winding the boost right up, but being as I more or less have a completely one-of-a-kind setup (almost everyone else has lower or lowered CR's) I'd like to keep an eye on the pressure between the head and turbo. I've read that at best the exhaust pressure should be somewhere similar to intake pressure to help reduce the possibility of excess backpressure blowing the headgasket etc. Also I'm just curious

Tiger seal wont work. Use GTP exhaust assembly paste - heatproof and swells up as it cooks to seal joints. I used Tigerseal on the exhaust manifolds to heads on my SD1 V8, that's held up extremely well so far! I read about using silicone type sealant years ago being fine as the head acts as a heatsoak. I do have some exhaust paste, it did a good enough job of sealing up both of the turbo flanges

Either stick a V8 or turbo infront of the straight pipe Putting some 90 degree bends in and a large straight through silencer could help, but that's unlikely to fix it sounding like the exhaust has fallen off
