Thanks,

From what I can tell SNR 4.412.912 has the new style impeller, so the ceramic seal, oil seal, impellershaft and oilseal in the ign. housing should all be ordered. As well as the 2x 5x2mm o.rings in the ign housing. Right ?

Hi Tomas

I would say yes. There is only 1x o ring in the housing.

I know someone who put the bolts in the wrong positions when rebuilding an engine. Don't look at the drawing to identify a bolt but check the length instead. Some of the hex screws are drawn as hex bolts, so check the length.

There is an allowance for a leak at the weep hole. The allowance is in the book and says basically that some weeping is allowed within one minute of shut down. Read the manual. You may be buying trouble you don't need..
I was out of limits.

No matter what, I pulled the engine out today and wanted to replace theese parts. I will also start using evans witch does not boil and cause pressure and therefor hopefully casuse less pressure and stress on the new seals. The impeller shagt did also have a slight grove from the oilseal on it, and the oilseal and ceramic seal looked like a mess. See pictures.
