MKV Toyota Supra A90 B58 Oil Breather Cap

With increased boost comes increased cylinder blow by on the MKV Supra – The crank case becomes pressurized and can damage the valve cover, and even push out the front or rear crank seal.  Through intensive real world testing, we have come up with a simple and effective two part solution for those cars running on upgraded stock turbo, or even an aftermarket kit such as the Pure 800 or Pure 850 turbo.

1.  Install our cylinder head dowel pins to prevent pressurized intake from blowing the valve cover out, see link here
2. Install this oil cap replacement which has 10 ORB threads on the top, and will allow you to vent the crank case into an auxiliary oil catch can setup.  This oil cap is a simple replacement that will install just like the stock oil cap, but will allow crucial crank case ventilation without making a mess.  We do not have a catch can kit available as of yet, but are happy to help put one together for you as well – Shoot us an email to inquire.

This kit includes one oil cap replacement with 10 ORB fitting on top.  A simple means to install an oil catch can and eliminate crank case pressure on all A90 B58 Supras.
