03 Dipstick Hard to insert

[Cbonilla]

I had my engine changed last winter (IMS failure). While I had periodically checked the oil level with the gauge on the cluster, this last weekend I decided to check the dipstick. The dipstick, which used to slide right in with just a little jiggling, now was very hard to insert. Multiple tries and needing to almost force it in.

I'm wondering if the plastic tubes that connect the trunk opening to the engine could not be properly connected or broken.

Would checking this be visible from the engine opening reached by putting the top in the service position? If not how do I inspect it?

Thanks, Carlos
