Questions About Start-Up Rattle

[lkchris]

Here's one possibility for dealing with the rattle It may be a short lived solution.

For cars with metal spin on oil filters, you get a new anti drain back valve every time you install a new filter.

For the 986, the anti drain back valve is in the plastic filter housing.

You can go to dealer or shop Pelican and obtain a new plastic housing + filter + o-ring as a single part number.

With a new anti drain back valve you may notice less or no startup rattle. My experience says this may or may not last until the next oil change.

But, there has to be a reason why Porsche packages this "kit."
