Leyland 498NT engine valve stem oil seals

Post #1 by oldtractor357 » Tue Sep 25, 2018 12:27 pm

Hi all,
I'm new to the forum and need a bit of help.
I'm rebuilding a Leyland 498NT engine and I can't find any info on valve stem oil seals. The head gasket set came with the folllowing seals:
8 Large square section seals
4 slightly smaller square section seals and
4 O rings.
I'm not sure which valves they go on, any advice on fitting seals and any drawings would really be appreciated.
Thanks in advance
Nick
