As the little man on Laugh In use to say..."Very Interesting!" There is a follow up Lycoming Service Instruction 1485A which might prove interesting (or Very Interesting) having to do with "new and improved" valve guide material shipped from Lycoming . If you have the new guides it is no longer necessary to complete the mandatory 400 hour inspection in the latest revision of SB No. 388 . It is "recommended" that the inspection from SB 388 be completed at 1000 hours or 1/2 way to TBO . New valve guide material was introduced in 1996 and since March 1998 all engines , cylinder kits and spare valve guides contain the new material . ![]() RB ![]() |

This is very true, My good Rich. ...However, my engine man, Herman, says the issue was/is not completely fixed by the introduction of the new and improved guides. I have also been advised that MMO (Marvel Mystery Oil) goes a long way to keep things running smooth. When queried a few years back, a noted Lycoming rep said, "It can't hurt." |

We used synthetic based oil . had no problems . The 98 oct mogas has cleaning agent it keeps your valve and engine components clean i use periodically J.P.. |

Where do you get 98 octane? I think 92 is the highest rating I have seen in mogas. |

You know that MMO is now owned by the Turtle Wax company, right?? I recall "hearing" that an NTSB report/analysis of MMO found constituents included mineral oil, Stoddard solvent, and lard!! I'd buy some if "Hidden Valley" owned them. (See Cobb salad reference above) |
