.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!
intake .010 exhaust .012
Inlet 28 mm .exhaust 33 mm
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.
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.
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.
Sounds more like an air issue. Check the air intake hose (between the air filter box & engines intake manifold)
E5, book says engine warm. Intake: 0.25mm (.010in) Exhust: 0.30 (.012 in)
There are 8 spark plugs. 4 on the intake side of the head and 4 on the exhaust side.
