just curious but my h22 came too me with nippon denso plugs and rotten wires...lots of carbon on the pistons and a worn input shat bearing.....

at what milage does the input shaft bearing usually go at ...cause i know this motor has way more than "50K"

plust ive put about 50 on it my self mabye the input wa fine then

 

well, i found out from a friend who lived in japan, and he says that its true that a lot of the engines are low on mileage but have millions of idling hours on them due to the traffic. my "low mileage" engine was very worn out and had to be rebuilt after only 9 months and well under 6000 miles of my us
