Yeah did a oil change Saturday. Had done 7000 so will change at 5000 now religiously it disappeared at idle after the change and is only 2800-3200 on no6 under gentle acceleration in second? Rattle rattle - gone? No noise with 6 coil pack disconnected! Weird.

how loud is it? 
 
not sure if you can use an oil flush to get the gunk out... they arent too bad to clean apart from having to get them out. there are also a couple different varieties on our engines. look the same externally but different sizing internally

Haven't pulled the cam cover but goes away with no 6 H.t. Disconnected? So I would assume a cam lifter follower issue? Seeing as its on the exhaust side?

may sound like a dumb idea when your so confident of where the noise is buuuuuuuuutttt.......

 

its not an exhaust leak at the back?

Can only pick up the rattle in 2nd gear under mild acceleration?

 

 

 

 

U should have a lisren to my engine, rattles at idle (suspect the turbo may well be dying lol) about 3k its got a ting ting noise and at the top it sounds like a big ol straight six on heat ? 

Wouldnt be lifter, weather u disconect the coil or not it the lifters gonna do its job. However, if u disconnect the coil and it goes away ur taking the combustion away from that cyclinder. So id be looking for a leaky manifold around nunber 6 or anything in general todo with number 6

Yeah i panicked at first thinking ouch turbo, bearings, piston slap, gudgeon pin, big end knock etc. but can fully pinpoint the sound to no6 rear exhaust cam cover at only that tiny rev range. Will sus it out better on the w/end? Might need a real mechanic! Would assume tig welding it won't help!

Will suss it out better Saturday. Thanks for the advice guys, I appreciate it. It will give me a better starting point for trouble shooting. Never owned or worked on a car with a turbo or the cam shaft/s in the right spot except the last 8 months. Show us your v8's. She's running absolutely trick except for that! My wife and jack recond the noise is in my head! What noise! (perhaps the loony bin would be a better fix?) done all the turbo/dump pipe studs gaskets etc. So will check the manifold.
when you drive something often enough you can hear noises before anyone else or before it becomes a problem

Spent 3 months of weekends when I got it fixing rattles blips blurts knocks and bumps! Only drive her on w/ends. The captain always goes down with his ship. Then emerges with less money and More power!

I remember having issues with the escort (when I was 18) flushed and cleaned everything new radiator, heater core, plugs points gaskets leads jets etc. I was putting a new head gasket on when dad came out and wiggled the no.4 piston with his hand. Think I found your problem mate! Sell it now.

    • Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.
    • Does the scanner do all the CUs in the car, or only the ECU?
    • @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man
    • Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?
    • Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
