I dont think the transmisssion is up to the torque from the engine! Might be over reacting as I am again really pi**ed off with the car! Every time I think the car is sorted something else breaks! time to walk away and have a beer!Mike and LibbyNew diff ordered should be here tomommor.

SteveJP Posted September 20, 2010 Share Posted September 20, 2010 Made it to the Drivers meeting and back OK in the Spitfire, no real issues other than losing the tickover on the way home, - car ran well but incredibly noisy with the hood up - not used to this ;)Over the whole trip 280 miles door to door it did 42mpg so I won't touch the carbs now!Fitted some cheapo PC speakers in the front this morning to help drown out the rattles etc!Drained the oil and refilled with nice expensive VR1, topped up gearbox, checked water, points etc - now ready to go, just needs a vacuum to get rid of the 10CR crisp and sausage roll crumbs ;DTried the Stickers on the car - see my other message.Must stop tinkering Link to comment Share on other sites More sharing options...
AlanChatterton Posted September 20, 2010 Share Posted September 20, 2010 MOT passed!! Woooooooooooooo hoooooooooooooo!!Horrible front wheel wobble that I'm hoping is just balancing to sort, clean, polish, few miles, oil and filter change, sticker it up and we're away!!Phew!

AlanChatterton Posted September 20, 2010 Share Posted September 20, 2010 Andy.Few things to check first. The metering unit is the fuel metering unit, its next to the dizzy with all the pipes coming off it that feed the injectors.Make sure the timing and point gap are right.Make sure the valve clearances are right, if either of these are off, you get low vacuum and then high fuel consumption.On the side of the metering unit you will see a black rectangle with the word "lucas" on it. 4 screws hold it on, remove and take off the plastic cover.Inside you will see a roller on the end of a cam. Put some feeler gauges between this roller and the left hand side of it. this should be 57 thou EXACTLY. check and see what this is before you think about buying a new metering unit. Its fairly simple to check.Do this and then let us know what the measurement is. Link to comment Share on other sites More sharing options...

GreenV8Machine Posted September 20, 2010 Share Posted September 20, 2010 LOL. Reminds me of Beziers on the 10CR, as a 2.5pi member told me he'd put nearly twice as much fuel in his MkII compared to my MkI V8 Link to comment Share on other sites More sharing options...

Dribbly is not good obviously!The valve clearance is critical as Alan says, I was amazed the difference when I got mine right.You don't want the tappety rattle that is "OK" on a carb car. Nice and quiet is good!Then you ring Malcolm at Prestige.At 16.4mpg you will use more fuel than the cost of a recon metering unit. And a set of recon injectors. (Talk Very nicely to Mr Chinn about injector seals for a budget recon)CheersColin Link to comment Share on other sites More sharing options...
willows40 Posted September 21, 2010 Share Posted September 21, 2010 i took the cover off and as far as i can tell the gap is correct, Did do the tappets a couple of months ago but only started using it last week will check them again tomorrow, Also will check timing when i go over to ditchingham tomorrow, Don`t have a clue how pi systems work but would think i should get more mpg than i am when i get nearly 30mpg out of the 2500S auto on a run, What should i be getting in a pi auto?cheers andy Link to comment Share on other sites More sharing options...
andy thompson Posted September 21, 2010 Share Posted September 21, 2010 I got 21mpg from a well set up 1971 PI auto driving round Oz in 1992 - got 30mpg with mod :-/ Link to comment Share on other sites More sharing options...

About 14.6mpg it would appear.PI systems are very simple in their operation if it is explained by the right person!Jason uploaded a set of fault finding cards, they are useful as well.I would suspect lack of maintenance, old seals etc may be contributing to the thirst.I get 28-30mpg from a MOD PI, best is 36 on a run to Holland. Last RBRR was 26-28 being thrashed by my "mates"Time for a MOD box and sod the pain??? :-/Colin Link to comment Share on other sites More sharing options...

TRTOM2498 Posted September 21, 2010 Share Posted September 21, 2010 Hi All,It's the owner of the famous thirsty PI Auto !We got 16.4mpg, yes. The car is well set up, timings, mixture, and all butterflies sychronized.3 of us did the event, and we drove the car very hard, I guess harder than most. All service items are also new. I spoke to the previous owner, Andy Roberts on Sundy, who thinks the metering unit could probably do with being replaced, so something to look at in the future.On the 10CR last year, we had a mis fire, which was down to a cracked dizzy cap, and we managed 13.6mpg on one tankful !Great car though, drives superbly.CheersTom Link to comment Share on other sites More sharing options...

Reg Barton Posted September 21, 2010 Share Posted September 21, 2010 Enjoyed the run to Gaydon in both big Triumphs - drove up in the 2000TC and back in the Mk2 Pi!! However, took the Pi up the M5 this evening, and found that at 71 mph (or thereabouts :X) there's a very nasty vibration sets up in the drivetrain. This persists when the clutch is depressed - so Chris the co-driver, friend, and mechanic says it's time to change the propshaft. Yet another "little" job on the list then..... Oh, and to fix the music side of things, I've "bought" a Kenwood CD player off some plank in Gloucester via eBay, who is now playing hard to get with me going to fetch it - he obviously doesn't understand that I need it in my hand so that I can fit it at the weekend......

James Posted September 22, 2010 Share Posted September 22, 2010 MOT failed yesterday - nothing major just a bulb and a tiny bit of welding to the rear of the underside of the sill.Redone on Monday.Checked fluids - all ok.Resigning that EFI won't be on it but otherwise seems to be running fine - just inishing touches to do Link to comment Share on other sites More sharing options...
