| + | ==== Restricted Tappet Guide Drain Channel ==== | ||
| + | |||
| + | Oil from the rocker boxes drains down the pushrod tubes and enters holes in the tappet block to drain down into the gearcase. \\ | ||
| + | The drain channels can stop up sometimes. This backs up oil in the tubes and can cause a leak to form at the tube base. \\ | ||
| + | It could be the gasket or sometimes particles that have lodged in the holes. Try removing the tappet guide, clean / replace them and install new gaskets. ((ironheadjunkie of the XLFORUM http://xlforum.net/forums/showthread.php?t=1379395)) \\ | ||
| + | Some guides have one channel, some two, and there are some that have a spiral. \\ | ||
| + | Over the course of the motors lifetime, there's no telling what year or type of guides they may be since one fits all. \\ | ||
| + | But you do need to get it right, since the oil return thru the guide also lubricates the tappets. \\ | ||
