Sutek2009 Posted December 21, 2021 Share Posted December 21, 2021 Hello, Can anyone tell me what these holes are? There's no thread and they go down to what looks like a polished shaft. I did consider locating holes for wiring loom clamps. Quote Link to comment Share on other sites More sharing options...

western Posted December 27, 2021 Share Posted December 27, 2021 Those holes allow oil from the main gallery to access the cam bearing that are seated in the block, the 3 holes use the plugs linked to above to stop any leakage out of the block or any unwanted debris in. 1 Quote Link to comment Share on other sites More sharing options...
