Briggs and Stratton Intek V-Twin Bent Push-rod and Cylinder Head Replacement



This is my first how-to video that documents the repair effort of my Craftsman lawn tractor with a Briggs and Stratton Intek V-Twin 21 HP engine. The engine began emitting a loud tapping sound from under the rocker cover. Soon thereafter, it began running unevenly as if one cylinder was no longer firing. This video reviews the diagnostic and repair procedure to replace the bent push rods and cylinder heads. It also covers adjusting the valve clearance and has some tips and advice to help avoid this problem on your air-cooled engines. Please feel free to leave comments on how I can improve for future videos. I consider myself handy, so if you would like to see other repair videos, let me know and I can see what I can do. Please like my video if it provided valuable information for you.

I purchased the parts from Amazon to get two-day shipping. If you can wait and prices are comparable, buy from your local small business to help support them. Here are the links to Amazon for the parts specific to my engine:

  1. I also had the valve guides move out of place on my B&S Vanguard Vtwin. I stuck them in a press and drove them back in. I set valve lash, re-assembled, and the loud valve noise went away. Next time they ought to be welded because I have a feeling it will happen again.

    I replaced the original B&S Vtwin due to a cracked block (video on my channel) and that engine also had valve guides out of place. I have a video I can share of the valve guides being pressed in as well. Endless cylinder problems…

  2. Replacing the head is not a solution,that is a 300.00 dolars every two years plus labor it cost me twenty dolars and will never had a this problem again
