I believe what comes out of the block is round, but I need to go down to the boat and verify that. Will do so in the weekend.
What makes it a little complex is that the oil cooler is combined with the oil filter
It feels like I have to work on two tracks in parallel:
1. Try to fix the tubestack and test it under pressure
2. Try to find an oil filter
housing that fits directly onto the block - skip the cooler
After the oil mess this summer a simple oil filter housing just to bolt on could serve as a good spare part to have onboard.
And this is Sweden
, we are not really in a tropical zone and my cruising speed is at 1500rpm. So the oil cooler might not be needed, but I would feel more comfortable if there was at least one marine
4.236 that had gotten rid of it before me
