The entire center of the flex plate had broken out and was only still driving the torque converter because it was wedged in there, and a small piece had gotten itself stuck between the flex plate and torque converter, which is what pushed the flex plate into the engine block.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/mechanicalmalarkey.com\/wp-content\/uploads\/2023\/01\/2023_02_27_03.jpg\"><img decoding=\"async\" src=\"https:\/\/mechanicalmalarkey.com\/wp-content\/uploads\/2023\/01\/2023_02_27_03.jpg?w=800\" alt=\"\" class=\"wp-image-6022\" \/><\/a><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This picture shows where the flex plate was grinding away at the engine block, fortunately not enough to cause any problems.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/mechanicalmalarkey.com\/wp-content\/uploads\/2023\/01\/2023_02_27_04.jpg\"><img decoding=\"async\" src=\"https:\/\/mechanicalmalarkey.com\/wp-content\/uploads\/2023\/01\/2023_02_27_04.jpg?w=800\" alt=\"\" class=\"wp-image-6023\" \/><\/a><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">You can tell which area that was because it&#8217;s discolored from the heat of scraping against the engine block, and you can see where the tiny bit of metal was stuck. I tried to match up the broken out center piece but couldn&#8217;t figure out how it originally fit. It&#8217;s surprising the car was even still driving.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/mechanicalmalarkey.com\/wp-content\/uploads\/2023\/01\/2023_02_27_05.jpg\"><img decoding=\"async\" src=\"https:\/\/mechanicalmalarkey.com\/wp-content\/uploads\/2023\/01\/2023_02_27_05.jpg?w=600\" alt=\"\" class=\"wp-image-6025\" \/><\/a><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The tech that fixed this said that the only thing he could see that could&#8217;ve caused this was that when the torque converter was recently replaced, the dowel pins that locate the transmission to the engine were missing, so it only had the bolts holding it in position, so it might&#8217;ve been just slightly out of balance from not being correctly located, which stressed and broke the flex plate over time.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\" \/>\n\n\n\n<p class=\"wp-block-paragraph\">New blog post or video every Monday, plus pictures throughout the week on <a rel=\"noreferrer noopener\" href=\"http:\/\/facebook.com\/mechanicalmalarkey\" target=\"_blank\">Facebook<\/a>, <a rel=\"noreferrer noopener\" href=\"http:\/\/twitter.com\/mech_malarkey\" target=\"_blank\">Twitter<\/a>, and <a href=\"http:\/\/instagram.com\/mechanicalmalarkey\">Instagram<\/a>!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.youtube.com\/channel\/UCasCW0ImD3UuLeMu5RAZCXg\" target=\"_blank\" rel=\"noreferrer noopener\">Watch Mechanical Malarkey on YouTube!<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mechanical Malarkey <a href=\"https:\/\/mechanicalmalarkey.com\/merchandise\/\" target=\"_blank\" rel=\"noreferrer noopener\">T-shirts, hats, and stickers<\/a> are available to order!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">-Dan<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A Honda CR-V was driven into the shop with a bad tapping or knocking noise coming from the engine area.
