Any one know where to get valve steem seals for a contenental G176 gas engine? It is in a 3165 loader tractor. Getting a lot of smoke with no blow by from breather. I'm thinking oil might be running down valve steems? They show some wear in the guides. I was going to try Napa today? Thanks,Dick
 
I use VALVE stem seals from SUMMITT RACING EQUIPMENT:

1-800-230-3030


Once these SEALS are installed you MUST check to see if they interfere with the VALVE travel:


Seals should come with a through away protector to protect the I/D of the seals as placed over valve stem:


Ask for technical support and give them the VALVE STEM DIAM. and the OUTSIDE DIAM of the VALVE guides:

You could also check with a local HEAD REBUILD shop:

Perfect Circle will have the seals. Man when I worked for Dana we sold them several ways + we had about 4 different types. You may need to machine the guides too. I will look in an old Perfect Circle catalog tonight and get you some numbers. J.
 
The MF part number is 839042M91 according to the book I have it says the intake valve stems are .340" in diameter (.343" is 11/32" diameter which is the valve stem size small block Ford, and small block Chevy V8's). I'm still looking for a crossover part number for the MF 839042M91.

Perfect Circle was bought out by MAHLE.
 
The valve stems are .340" in diameter, and the valve guides should be .658" outside diameter. The only thing I can't find is the inside diameter of the valve springs, once that is known then you should be able to locate some sort of valve seals that will fit. If anyone knows the inside diameter of the valve springs, if you can post it I can look up valve seals with those three measurements.
