    that has to be an intermediate version. If you look and the picture I posted it has the ratchet setup. Pretty nice as it would maintain a minimum of slack in the chain as the chain stretched and slippers wore. I found this when doing a head gasket and then another at a pick and pull on a motor...

    I can't tell from that pic but the one side would have a ratchet setup. I can't find mine but here is a web pic, not so clear you would press down the tab so you can depress the piston and then place the hook on the peg to hold it in place. the part number I searched on is 13540-66010, not...

    I’ll tell you exactly what happened and it will likely happen again if you don’t relay this to the new mechanic. The slippers are tensioned hydraulically. Oil pressure builds and pushes the tensioner piston out and against the slipper. Some people associate a startup rattle with the tensioner...

    Not sure how well they work but they have those endoscope cameras for a smart phone. Just need to take off the throttle body (4 12mm bolts) and feed it down the front runner.

    Mechanic Fixed Head Gasket, At Completion Tells Me I May Require Engine Rebuild

    sorry guys but I've been battling COVID for the last 7 days so my thoughts have been a little choppy. I'm stuck on the fact that 1 mechanic gets good compression on cylinder 1 and another shows only 65lbs. So I worked through the process in my head trying to account for this. For the benefit...

    Here’s an idea, buy yourself a tool kit and have a go at it. How much worse can you make things? Start a new thread, we’re here for you and ignore the enormity of the project and concentrate on the task at hand at that moment. A lot of us started this hobby in this very same way.

    Mechanic Fixed Head Gasket, At Completion Tells Me I May Require Engine Rebuild

    When I had heads done my shop wanted the head, shim buckets and cams to do the job. After straitening the head and grinding the valves they would set the gap on the cam shafts and then reassemble. Upon receiving the head I would remove the cams, install the head and finish the job. Without...

    A valve retainer might have slipped out from not being seated properly during head work.

    I agree. I’ve done this a couple of times one engine with some visible marring on the crank. I take some fine grit emery cloth wet with isopropyl alcohol and clean the crank surfaces to ensure there isn’t any old bearing material stuck on. The truck with a bad knock and marring has been in...
