Re: 9 1/2 Engine rebuild and other stuff

Hi All Next problem is no idle. It just disappeared after ecu got a proper ground and everything was back to more normal. TPS is adjusted, but air screws are closed as many of us have when throttles are balanced with this rod and now i think they should be opened but how much? As i recall one thrott...

9,5 Wind shield and front springs

Hi

I have these parts over.

Springs ok and windshield (org) is possible to repair as it has some scratches on.

Just make a bid.

Re: Start motor

Forgot to mention...

One scary thing is to remove flywheel, but last time used Air Impact Wrench as they use when removing and tightening car wheel nuts professionally. Works like charm with some heat and proper puller.

Re: Einlassventil verrust

Hi We need to think by exclusion and a few things are clear already. When only one valve is suffering of this, then it is obvious that oil must come in very near of it. This is between valve stem and valve guide, around valve guide or there is a hole in intake channel..? Oil coming from here (red ar...

And discussion about front cylinder right side intake valve contamination.

It would be interesting to know if we have anyone who do not have this problem as per my hypothesis problem is by design.

Re: Einlassventil verrust

Hello

...one hypothesis left is to install one way valve and hope it will create under pressure in crank case thus reducing pressure which pushes oil in to intake channel

Re: 9 1/2 Engine rebuild and other stuff

Removing dynamo will rise TPS to 2.4 but removing regulator have no effect. Connector of regulator is heated up (red arrow), but operational. This may be side effect of similar melt down: https://www.ital-web.de/forum/viewtopic.php?p=53175#p53175. Cause of this i replaced connectors with straight wi...

Re: Einlassventil verrust

Hi I have same problem and valve guides are new and sealing is changed three times now, which did not help any. There is no oil in air box, so blow by function cannot be directly guilty for this, but maybe blow by function is creating a shock wave under the front valve cover and this pushes oil thru...

Re: 9 1/2 Engine rebuild and other stuff

Hi You have right. There obviously has been some problem with original ground cable, but now it is solved for ECU at least. This episode might be the root cause for the ground problem: https://www.ital-web.de/forum/viewtopic.php?p=47421#p47421 At the moment only part i am still worried about is regu...

Re: 9 1/2 Engine rebuild and other stuff

Yes Wire from battery to ECU fixed all problems discussed. Now idle TPS is between 2-2.1 when warm. First TPS value is changed accordingly from standard 2.4 -> 1.9 Now starting is easy, idle stable and engine feels sharp. Conclusion: if your TPS is below 2 or you have strange errors. Then you might ...

Re: 9 1/2 Engine rebuild and other stuff

Hi Jogant

Connecting diagnostic tool ground to battery removed errors and TPS fluctuation.
Now even measured values makes more sense. Tomorrow i will make permanent ground for ECU and try different ignition maps for good starting.

Thanks a lot!

Re: 9 1/2 Engine rebuild and other stuff

Saldo of yesterday... Went thru wiring diagram, but it is hard to check if all earth wires are ok. Need to think this over... As you see there is one new error. P0105 It came after i removed sensor, just for testing and put it back. No sure if i had electricity on, but this caused yellow light to co...

Re: 9 1/2 Engine rebuild and other stuff

Hello guys Some problems solved :) By changing back the mapping 2 degrees issue was solved. Furba obviously is based on Granpasso mapping as per Heinz. Lambda was on. Removing dynamo did not help. Checked also airbox connectors and wires. They measure ok and looks good, both sides. Ordered a new TPS...
