Is it easy to replace piston rings in a 2000 VW Jetta?
Only if you are a well-trained mechanic that has experience working on VW engines. I know a lot of mechanics that won’t touch any German car because (a) the parts cost a fortune and are hard to get, and (b) German engineering can be very squirrely and you may need specialized tools to get any job done. So unless you really know your stuff, I wouldn’t advise trying to do that yourself. Replacing piston rings is MAJOR engine work that requires you to practically tear the whole engine apart. Getting it apart isn’t the problem — putting it back together and having it work properly is.
It will cost you an arm and a leg, and possibly your first born child if there is clyinder scoring or something wrong with your pistons. Buying a new short block would most likely be a cheaper solution(if there is a problem with the cylinders or pistons). Then you can keep your leg, and your first born, but you’ll still probably lose your arm. These guys have good prices on VW short bocks they are all new, so you don’t have to worry about whether or not they were rebuilt properly, which is a risk that you will run when you get your piston rings replaced. http://www.eurospecsport.com/eurocat.htm… PS find a mechanic that doesn’t demand payment in body parts.
