TICKING SAMI
4x4 AnswerMan,Recently re-built the 1.3L motor in my 86 Samurai and it was great ... at first. Within 1500 miles the valves started getting noisy, so we readjusted them and it was as quiet as a sewing machine, then again within 1500 miles it started sounding like a diesel again (the cam was mic'd and found to be in spec. and the head was sent out to a machine shop for a 3-angle valve job).
Why won't the valve adjustment hold up any longer then this amount of mileage? I almost never rev above 4,000 RPM (my daily driver). Please help me with this. I'm going crazy constantly setting valve lash.
Thanks,

Hi Carl,
I understand your frustration, but no need to go crazy?we already have too many running around. There can be a number of factors as to why your valve adjustment keeps changing. Without knowing all the facts it?s really hard for me to say exactly what is causing the change in valve lash. In all honesty, it can be that the engine is simply breaking in the new parts added during the re-build (e.g. valve springs).
My recommendation is that you take it back to the person who did the re-build. They should be able to give you some direction on why this is happening?and hopefully a solution.
Good Luck.
