here's the deal. I replaced the timing belt on a friend of mines 2003 passat 2.8. everything went smoothly, replaced tensioner and water pump as well. car was running perfect for 2 whole months, until a week ago she said it started to idle high (around 2-3000k). still ran fine, just had a abnormally high idle. a couple days later, she tried to start the car and wouldn't budge.
I just now looked at it, cranked it over and sounds like it has no compression. this stumps me because I know that it was perfectly on-time. it is sounding to me that the belt has slipped, but what could cause this?
thanks in advance.
