It is ALWAYS good to get a second opinion. I would highly recommend taking it to another shop and have them tell you what they think it is even if you believe the first shop to be right. That being ...

How to test for a leak in the exhaust manifold gasket?

Seeing as how your car has a turbo, the only place it would be leaking and you'd hear a ticking noise is pre-turbo, so the exhaust manifold at the head (header) and the down pipe on the hot side to ...

Should a sealant be used, or not, when replacing a molded rubber valve cover gasket?

Generally you don't need to use any sealant on this type of gasket, mainly because the gasket is pliable enough and will seal on it's own. If I were going to use any sealant on it, it would be where ...

Can you retighten timing chain cover without redoing RTV?

As long as you are not breaking the two pieces apart (completely removing the cover), you should have no issue doing what you want to do. I'm assuming the RTV which is there is fully cured? If so, you ...

Should a sealant be used, or not, when replacing a molded rubber valve cover gasket?

You don't need a sealent on this gasket. The new gasket will stand much prouder than the flattened gasket you'll be removing, and the WSM doesn't specify sealent anywhere. Torquing the cover down to ...

How can I open my thermostat cover which is stuck due to using too much gasket maker material?
