I have recently taken all my valves out and cleaned them with a wire brush as well as the shafts in the cylinder heads. I am now getting ready to put them back in and have several questions:
- What indicator/sound should I be looking for to signal that the lapping of a valve is done properly? I understand you should lap them until a certain sound comes out, which means the seal is ready.
- I assume the valve stem should be lubed especially along the portion that goes through the guide. Should I use regular machine oil or the engine specific oil (in my case 5W30)?
- Should I lube or grease the keepers before putting them back on? I think some grease may actually make the precise job of setting them easier as it adds adhesion.
