But you have to know that I have this plugs from march or april .
It can be that there was only a few plugs with issues .
I remember that years ago I got a similar problem with Nova plugs .

I think I was only unlucky . Hope the engines will run well now .

When did you change conrod ? After how many hours or liters ??
I dont know BP´s for so long and my 3 engines are pretty new . A friend of me from swizerland told me that I have to change the conrod very soon . He ment after 2-3 liters max .
Further he told me that he changed the conrod and wristpin with the R7 of Nova and that this combination worked better . Because after run in the conrod gets broken after 1 liter .
Can you give me some information about how long the conrod can be installed?
