Tech - Modifying 2JZ-GTE valve covers for AN fittings, removing baffles

I decided to make a video on how to modify a set of MKIV Supra 2JZ-GTE valve covers for use with a catch can since I really didn't see any other videos out there on this topic.

The GTE valve covers have permanently attached baffles. The hardware used from the factory is rivets, so the baffles are much more difficult to remove than the 1JZ and 2JZ-GE valve covers which come with bolts from the factory... but this can easily be changed to a more serviceable setup by drilling out the rivets and drilling and tapping thread into the covers. This is the cleanest way to do it, and make the covers serviceable in the future as well.

In this video I show how to remove the baffles, weld on AN fittings, drill and tap the covers for bolts, and clean up after you get them back from powder-coating as these will have to be sandblasted also... so you need to make sure to remove all that sand and sand residue.

Now offering this as a product/service if you want to send in your covers:
