My friends 2011 Corolla developed a bad noise, he had it checked and it was determined timing chain (233,000 miles). He didn’t want to pay the $3000 to fix so I gave him $1500 and a 85 Nisson truck. WELL after putting a recommended quart of trans fluid in it was quieter, then checking further I saw the oil sending unit squirting out the fluid I had just put in. I pulled dipstick and dry as a bone!! (I drove it home 17 miles!!). So $22 sending unit, 5 quarts of oil, purrs like a kitten. Checked trans and it didn’t show on stick (1-1/2 quarts to get to mark) I think I came out real good on this car! DMV assed value was $6000. He cheaped out on a lot with this car but I’ll get it back to nice again, no rust or dings. Opinions?
