about the St. Moritz meeting... It^s sold out... maybe i'll try to be at freddys...

So, after another day of: - Changing inlet manifold gasket (to get a better look at the valves) - Changing all the Injectors (from another engine) - Test Drive - Changing the ECU and Immobiliser - Test Drive The problem is solved... IT WAS THE ECU! Now it's running like hell ... Thank you all and specially Andrew for the help!!!! Regards Patrick

no news... was abroad working... ECU arrived this week... tomorrow there will be news!

Hi Andrew The Plugs on Cyl 2-4 look all the same (almost white coated). I bought an ECU on Ebay today (complete with AS5 and FOB)... I hope the Parcel arrives until Friday*driving*....

Hi Andrew I will be away the whole next week (working to get the money to try every possible solution*loser*)... Next weekend i will try your suggestions above... Exhaust is standard as described by you. I'll try on... patrick

Here pictures of the plugs: The right one is cyl 1.... The left one was on Cyl1 before, after approx 15min running the black surface changed to almost white...

Do I understand correctly that you have re-used an EU2 cam cover to allow you to use the original EU2 ignition components, loom and ECU on what is otherwise an EU3 engine (with bigger throttle body, stronger pistons etc.)? Exactly, but i used the original TB, Injectors, Inlet Plenum.... From the EU2 Engine. So basicly it's just the Block and head from the EU 3 Engine, all the electrical components and anciliarys are from the EU2 Engine...

Hi Andrew A VVC EU2 Engine was already fitted in the 7. i took a EU3 Engine, rebiult it, took all the sensors and the head-cover of the old engine and fitted these to the new one. Si i don't thin, that the fault is a general wiring fault... 1) and 3) i already checked. 2) i will try to get a complete ECU to test this out 4) There is no leakage of coolant, there is also no white smoke from the exhaust 5) there is a tapping noise.I can' t lokate it, where on the Engine. The old engine made approx. the same noises, so i was thinking that this could be normal with the VVC engines. When i took of the Cam Carrier i tryed the lifters if they are hard. all the Lifters felt like pumped up... 6) the Piston in Cyl 1 looks wet (not as much now as before, when Plug was also wet). I swapped the Piston with a little piece of cloth and tryed to find out if its Petrol or Engine oil. i'm not shure which it is,but i think it's Petrol. All the gaskets on the Engine habe been changed while rebuilding. I will post a picture of the plugs tomorrow, so maybee you can see if its running lean on the other cylinders... Thank you for the good inputs...

Hi Blatchat This is my first post on Blatchat… some info about me, my name is Patrick, living in Switzerland, Seven owner since 3 years. Last year i started to rebuild a VVC Engine (160PS from a MG) to fit in the 7.So far no problem (with a little help from my friends and some mails with DVA*smile*). Fitting the new Engine in the Car also no problem. The following modifications have been made: - Lighter Flywheel from TTV Racing - New clutch (also delivered by TTV) - EU Head Cover - Timing of the Camshafts - New Lambda-Sensor When i started the Engine first time idle was at about 1200RPM. When checking the Plugs, first Plug was wet and black the other 3 Plugs in a light brown (ok according to mi colleague). I changed the following: - Changed Injectors Cyl 1 - 2 - Ignition Leads - Ignition Coils (delivered by Elise-Parts) After Changing of the Ignition components, there was no change in the behavior. I took a ride and found the Engine lacking power, lots of rough running and missfires. I bought a PSCAN-Interface and found out, that the VVC mechanism is stuck in the fully increased position (290°). I then fixed this by taking of the Cam-Carrier and honing the bearing surfaces oft he crosshaft. Afterwards VVC is working properly, angle is 223-225° at idle, idle is around 860RPM. Compression measured, 15 bar on all cylinders the same reading. But Cyl 1 still running rich (Plug wet and black). I cheked the live-data again with the PSCAN and found out that the Oxygen-sensor shows a very low reading and state „inactive“. I changed the Lambda-Sensor with the old one, now the readings are correct. Afterwards i took another ride. The Engine is running ok (but not really good). After the ride (of approx 15min) i took out the plugs. Plug of Cyl 1 is still black (but not wet), the others are gray-brown. Big question is there anybody out there with the answers, whats wrong…. Greetings Patrick edited: added changing of injectors, measuring of compression.
