G320 Pro-Active don't Run

[Clubin]

Yes that’s the wrong gasket. That’ll never work that way.

 

[Freddie1971]

I know

 

[Rep732]

Glad you found the issue

 

[Freddie1971]

So am I .

Thanks again fore youre help in this matter.. have a great day.

 

[Freddie1971]

Well that was a disappointment.

Hmmm maybe i gotta start praying.

There is a littel dispost on the piston, the rest looks normal. The outtake is pretty wet frome the oil. I don't now if thats a problem.

 

[Rep732]

If I'm not mistaken the top of that piston is hammered and beat up. That's not good at all

Yeah, from the picture it looks pretty fugly.

 

[Freddie1971]

I saw that. But that can not be reason the engine don't suck up any gas. Sparkplug stays dry.

 

[Bizzer]

If that’s an indicator of the condition of the rest of the top it might!. Are there any scores on the cylinder walls, does it have the same compression it did when new or is it lower?

 

[Freddie1971]

That Engine is Dead...

Cylindergasket was completely gone.
Piston was indeed hammered in cylinder masive movement in the crankcase.

 

[Bizzer]

Unfortunate but now you found the real cause! If your up to the task buy a top end kit and do a rebuild, but I’d do a complete rebuild and make sure the no trash has found it’s way into the bottom end!

 

[Freddie1971]

Thanks...but i have asked advice from Kingcobra.co UK. They have build the engine.

 

[Rep732]

That engine swallowed something that it shouldn't of had. I'd stop right there because that's what caused it to stop running.
I don't think king cobra is going to help you honestly, order parts from DDM and rebuild that engine. I personally would tear it down completely because the way that piston looks as whatever it ate could be lingering in the bottom end somewhere.

I think it was the cylinder gasket. There was nothing left of it.
I want to thank everybody who has try to help me in this matter.

Much appreciated

I suspect they heve never placed a gasket between cylinder en motor house ( can emagine it completely gone). Ik found some residue that was elastic, i think they put liquid gasket between the cylinder that will resolve fast.

 

[Rep732]

That's bad news there. Always need a base gasket!

 

[Freddie1971]

Kingcobra.co told me that this reactive motor never use a normaal gasket. Reactive motors use liquid gasket .

Bought myself a new enginge The zenoah G320F3. Hopefully this last longer

 

[Seandonato73]

You don't need a base gasket if the squish band has been cut. Something let loose inside that engine. That should have made some serious noise running. Also why arnt you running the standard ngk plug?

 

[Freddie1971]

This was mine first reactive engine. I now now that there is no base gasket fore that.

I bought this engine frome a friends if mine with that ngk plug (fore mine next engine i will use the standard plug fore sure).

This week i will assemble the engine to see what went loose. I will post mine findings here.
