Formula 1 Subaru Flat-12

Formula 1 Subaru Flat-12:

In 1990 Subaru took over the Coloni Formula One team, acquiring a 51% ownership stake, paying off the team’s debts, and supplying a new, unique engine. The engine was a flat-12 called the “MM” series, which in fact was penned by Carlo Chiti.

Chiti’s Motori Moderni company at Novara had supplied V6 turbo engines for the Minardi Formula One team from 1985 to 1987, and in 1988 Chiti had penned a naturally aspirated V12 engine that attracted Subaru. In late 1988, the Japanese commissioned Chiti to design a new Formula One engine with a “flat” layout, as used in their road cars.

The engine was completed in the summer of 1989, and was tested in a Minardi M188 chassis; due to a severe lack of power, Minardi lost interest. After a few months of searching, Subaru found the Coloni team. Eventually, the Subaru Coloni team was founded with Enzo Coloni staying on board as the man for operational business.

Valve Cover Gasket replacement Subaru WRX:

Valve Cover Gasket replacement Subaru WRX:

This is a step by step guide on replacing the valve cover gasket on Subaru flat four engines. This guide will work for most Subaru turbo cars 02-07+ and most other naturally aspirated Subaru cars.

1.) Jack your car up and drain the oil. Remember to put the car on jack stands. You don’t want the car dropping on you.A lot of people do this job with the oil still in the pan, but its better to rather play it safe and drain the oil completely.

2.) Remove the front air scoop. It takes two 10mm bolts.

3.) Remove the nice Cold Air intake box.

4.) After removing all that, you should see this a total of 8 outer bolts and the 2 inner which holds the spark plug coils.

5.) Unscrew them and label them. You don’t want the bolts going into the wrong place. It was a very hard to get any decent clearance so take your time.
