Valve guide

jamestedNovember 10, 2013

I have a 21 hp briggs and stratton vanguard twin cylinder motor. The model# 385777-0349-E1. The valve quide bushing has come loose. Briggs and Stratton has a replacement part# 692057. I have heard that when the quide comes loose you have to replace the head. So why does b&s have a replacement part and can it be fixed without replacing head.

Hmmm, a Vangard. Some claim to have a fix w/o pulling the head that you could try, but other than that just replace the head. Push rods should be checked also.

The push rods are bent i'm sure thats a result of loose valve guide bushings. I'm open to a fix without replacing head. Any suggestions?

Well I am a way late, computer has been in the shop. None replaceable valve guides pertain to B & S Intek engines, Vanguard Twins of that age were made in Japan and different Service Manual pertains. I do not know about reliability of replacement guides in Vanguard engines. I can furnish you with a Service Manual IF you like. Address below, put in proper format and remind me, engine model and what you want.

I don't claim to have a fix for slipped valve guides, I DO have a fix.
