AboutDavid Scott Expertise Questions regarding the advisability of different kinds of modifications to Samurai/Sidekick/Tracker or various kinds of off-road usage. I will not attempt to do more than provide links for questions about other Suzukis such as Vitara, Grand Vitara, etc. I may or may not give generalized advice for newer models, but have no experience regarding newer models, and will not attempt to give more than the most generalized answers for questions regarding vehicles later than '93 manufacture. I will however, if possible, provide a link that will help you contact a professional in your region.
Experience I've been a professional mechanic for over thirty five years, live in the center of the Rocky Mountains, and have been active in exploring the old mining/4wd roads for decades. I've specific experience with Samurai modification, because that's my personal vehicle.
Education/Credentials Thirty five years of advanced, intensive classes for experienced professionals only. Manufacturer seminars and training classes averaging four to six weeks per year. I'm now a professional heavy duty fleet mechanic, and no longer deal with issues such as MIL (check engine) lights

Question I have an 86 sami with a new motor,and had a diaphragm failure in my fuel pump. I,ve changed the oil and filter but the bottom end is knocking.
Can the new oil pump be damaged, and how do I check this(oil circulation)
The truck was in idol when the failure occurred, and I shut it down when It sounded like a lifter tapping.
Answer If the bottom end is knocking, then it's almost certainly a bearing failure. Remove the oil pan, and find out which bearing or bearings are a problem. Personally, I'd just replace them all. As for the oil pump, you will have to remove, disassemble, inspect and measure it to know anything for certain.
