Re: engine lock cap reference

OK. Thanks for the reference. Good idea change the rear sales. Do you know the reference to buy them?. Sorry, but my English it's not good and it's dificult to me to look for the tech names and the sellers.
Then I will look for too, how to change these seals.
Thanks

As long as they are listed for your vehicle you should be fine.
