.012 on intake .010 on exhaust
Manual calls for .012 for intake and exhaust with engine warm. I would go .010 on the exhaust and as low as .008 on the intake, factory lash is a little loose in most mechanics opinion. Set factory and it will be a little noisy, but its your call!

If you have ever looked at a Mazda bravo (b2500) you would know that it is not listed in the owners manual or placard under the hood, In fact I cant find it anywhere, By way of trial and error I have found the best clearances would be .008 in and .010ex , Ive had my bravo for a couple of years and cant fault it.AnswerThis information will be listed in your owner's manual and on a placard under the hood.
Inlet 28 mm .exhaust 33 mm
At TDC of the compression stroke for cyl #1, the cam lobes will be in a position such that they are putting no pressure on the valves, and valves are closed. At TDC of the exhaust stroke for cyl #1, the lobes will be in a position such that intake and exhaust valves may be open. Exhaust will be closing, and intake will be opening. There are two revolutions for the crank for one of the cam. TDC usually refers to TDC of the compression stroke, when valves are closed. This is when combustion/spark occurs, and is when the valves are adjusted on most engines.
On the Mazda 6 RF7J diesel engine, the intake valves are typically located on the side of the engine where the air enters, while the exhaust valves are positioned on the side where the exhaust gases exit. The intake valves allow air to enter the combustion chamber, whereas the exhaust valves enable the expulsion of combustion gases after the fuel has been burned. It's important to consult the specific engine manual for precise valve identification and configurations.
The valve clearance for a 1994 Mazda 323 with a 1.6L engine is typically set at 0.008 inches (0.20 mm) for the intake valves and 0.010 inches (0.25 mm) for the exhaust valves when the engine is cold. It's essential to follow the manufacturer's specifications and guidelines when adjusting valve clearances to ensure optimal engine performance. Always consult the vehicle's service manual for the most accurate information.
The EGR (Exhaust Gas Recirculation) valve on a Mazda 929 is typically located on or near the intake manifold. It is connected to the exhaust system and the intake manifold by hoses and is generally situated towards the rear of the engine. For precise location, it's best to consult the vehicle's service manual, as the exact position can vary by engine type and model year.
All Mazda B series engines are interchangeable.
just below the throttle body on the intake manifold an easy way to find it is to follow the little coper tube that goes from the front exhaust manifold to the intake.
There is no adjustment. The system is hydraulic.
