My 1994 Honda Accord Lx running richemission: failed emission test.


When the mechanical timing "slipped" the valve timing was affected. Valves can be bent if they strike a piston. Have a compression test performed on each cylinder. If the compression is low on any cylinder, likely the cause is a bent valve caused by the mis-timed engine. The cylinder head will have to be removed and the bent valves and valve guides replaced as part of a "valve job."

I have a oz xe 4.1 lt 250 xflow motor which i have rebuilt and put flat top pistons in bored out 60 thou shaved yella terra head 15 thou and has a very mild cam after lining up timing marks the inlet


when setting up the valve timing it is always done on the exhaust stoke.. Place the piston on TDC and set the valve timing so that the exhaust valve is just closing and the inlet is just opening. Rocking the crank a bit before tdc to a bit after tdc will produce a movement where the exhaust starts to close as the inlet starts to open. This is known as valve rock or valve overlap. The cam modification is of no consequence as the as all that is modified is the valve duration , not when they open or close. With the cam now timed to the crank turn the crank 180 degrees and set the ignition timing to the degrees advanced recommended ( 10-12 degrees bftdc is recommended for starting). Place the HT leads in the correct firing order and when running use a timing light to adjust ignition timing. If you are fitting a new cam then you must bedding in grease and when the motor starts it has to be run at around 2.000rpms for around 10 minutes to set (harden) the cam lobes or else they will wear off very quickly.

What is codes p1111 and po447


the valve timing solenoid is what advances /retards the valve timing according to the requirement pre-set in the CPU program. If this solenoid is malfunctioning then the valve timing will be out and the cam shaft position sensor becomes unbalanced with the CPU setting and raises the fault code

The vent valve solenoid will produce problems with fuel flow and running and filling of the tank. I suggest that you have both checked and repaired by an accredited specialist shop that is conversant with you car.

I HAVE A 1998 EL FALCON. WE REPLACED HEAD AND FITTED NEW TIMING CHAIN AND GUIDES. BY FOLLOWING MANUAL WE HAVE SET VALVE TIMING MARKS. BUT VALVES ARE OPEN WHEN SHOULD BE CLOSED. HAVE EVEN HAD FORD EXPERT ...


the piston has to be on tdc
the valves have to be in the valve rock position
that is the exhaust is just starting to close at the same time as the inlet is just starting to open
the number of links should now be at the timing marks or the timing marks should line up when the crank is turned one full revolution

Valve Clearance Valve clearance is there to allow the valves to cool in between combustion events (spark), and to make sure the valve closes properly and contains the combustion explosion. You need to cool the valves a little bit, the exhaust valve moreso than the inlet, as it's what sees the most heat as spent burnt gases go past it into the exhaust port. Run too little clearance and you'll cause the valve to "weld" a little bit to its' seat every time it closes, and then take seat metal off again when it opens. Do this enough times and you burn out the valve seat and need the head reconditioned. However, by running less clearance, the valve stays open for that little but longer, and you get more air in and out of the motor, and make more power. Run too much clearance and your motor just sounds like a diesel and loses power and tappet rattle annoys you while you're driving, so it's better to err on the side of caution.
The stock valve clearance (0.008" inlet / 0.012" exhaust, warm) is pretty good for any of the cams I've listed above, they're well-sized street cams, not really wild top heavy race cams that require super high compression to work, so don't be afraid to close the valves up a bit from the suggestions of the cam grinder, which will usually say between 0.010" and 0.014". There are a few ways to set your valve clearances:
Yellow Book Method This is from the factory 3K/4K/5K engine manual, aka The Yellow Books. It's the quick and lazy method.
Set engine to #1 TDC. Crank pulley timing mark should be on 0, distributor rotor should be pointing towards spark plug 1 or 2. Set tappets (counting from the front) 1, 2, 3 and 5. Rotate engine 360 degrees, crank pulley to 0 again, distributor rotor turned 180 degrees. Set tappets 4, 6, 7 and 8.
Nine Method I've never really gotten into doing this, takes too much time and maths for my liking :P Rotate the engine through its' range of movement, as one valve is "on the rock" of its' max lift, subtract the valve number from 9 and that's the tappet you should be setting. For example, if #8 valve is open, set clearance on valve #1. If valve #7 is open, set clearance on #2. And so on.
Stewart uses this method, and rotates the camshaft through its entire base circle and sets the clearance at the highest point. Which is a pretty good idea, as it compensates for the possibility that the base circle has been ground unevenly, and allows you to run the proper valve clearance that you want to run, instead of something that may be a few thou larger in reality.

1995 acura how do u set the vals and timming


First you will need a service manual or information for this vehicle for the valve lash setting. The procedure is usually removing the valve cover( You will need a new valve cover gasket) putting the # 1 cylinder on top dead center and using wrench, screw driver or allen key,and a feeler gauge. You will need to follow the firing order when adjusting the valves. You will need a timing light to set the timing and also the timing spec. This usually involves warming engine to normal operating temp. clean harmonic balancer and mark the timing mark with some white paint loosen the the distributor hold down bolt hook up timing light and turn distributor until the timing mark on the balancer lines up with the timing mark on the timing cover then tighten the holding bolt back down. Also the timing advance has to be disabled when setting the timing and enabled when you are done. The valves should be set first then set the timing. A Haynes manual available at your local auto parts store should contain pictures and information to help you do this.
