Hello Everyone,
I'm new to the forum and have a problem with my 2010 MK6 GTI. I recently bought the car from a friend knowing that it has engine problems. Here's my story and I'm hopeful someone will add their thoughts to this post.
I have a broken exhaust valve spring on cylinder 3 and am wondering if anyone has heard of this problem before or how common it may be. The car is completely stock except for a cold air intake. There are 85K miles on the car and the timing chains and tensioner were done at the dealer less than 10K miles ago. They were making noise before this was done but as far as I know it was caught and fixed before any timing jumped. The dealer has also replaced the intake manifold in the past but did not do any carbon cleaning when that was done.
It had miss fire codes on all the cylinders when I got it and the dealer said there was a hard miss on cyl. 3 and a valve was stuck open. They quoted an insane repair cost and offered to buy the car from my friend for a very low price. Needless to say he trailered it home and I have since trailered it to my place.
I have pulled the cam cover and can plainly see the broken exhaust spring on #3. Best I can tell the valve is in place and hopefully not bent. I pulled most of the rockers so I could index the cams to a position where they wouldn't continue to have force applied from the valve springs. Hopefully I didn't cause any damage by removing the cam cover before releasing the timing chains. I would think the cam bridge would be the only possibly affected part by doing this. I think the engine is still in time but have not removed the timing covers to look. I'm not sure how I would explain the misses on the other cylinders. I did find a torn diaphragm in the PCV valve when I removed it and thought this may cause miss fire codes.
I'm thinking I will need to open up the timing covers to release the chains, remove the cams and replace all the valve springs. I'm hoping the timing chains, tensioner are good to use again since the dealer was supposed to have done them so recently. I also need to remove the intake and do a carbon cleaning at some point.
Anyone done this work before? Thoughts about the situation? Things I should also be looking at if it I'm in it this far. I have searched and don't see very much about broken valve springs in stock engines without tunes or turbo upgrades. Thanks everyone!
