2006 JEEP COMMANDER #8 CYLINDER NO COMPRESSION AND TOLD TO REPLACE 4.7L ENGINE

What is your question?

Bought the jeep in April of 2018 knowing it had 191000 miles on it, but knew that 400,000 miles is not out of line. Ran like a new SUV, so I bought it for $4000. The engine was well taken care for and clean as a whistle......no problems. One month ago, I loaned the Jeep to my son to help his girlfriend move and he called me telling me of rough idling and slow speed. He took it to a mechanic who changed the plugs, but still no compression in #8 cylinder. I drove another car to his house and met with the mechanic. I paid him for the plugs and drove the SUV home 20 miles away. Made an appointment with my mechanic and he kept the SUV for 3 1/2 days while running computer tests. He said he put a camera into #8 and saw metal shavings and said he couldn't fix it. He suggested buying a used engine and having it installed at a garage he recommended. I checked around and found a used engine for $1350 and a cost of $2000 to install it. A warranty also. That's $3350+ and I am 79 years.

What makes this problem better or worse?

Nothing....it's all the same. Starts fine and runs up to 20mph

How long has your 2006 Jeep Commander had this problem?
