you will need some tools and valve clearance specification, i think you know that.here may be you are asking about the position of the crank for adjusting the valves. if it is rocker with adjusting screw you can adjust with that. if you have shims on the valve bucket under the camshaft then you can adjust by changing it to the proper size of shim.
* adjust any valve which is loose, you can check if the valve can be adjusted or not by rotating the crank about 30 degree clockwise and counter clockwise from the existing position and if the valve does not start to open and stays loose then that valve is in good position for adjusting.
* mark the Valves you have adjusted. * rotate the crank one more turn and adjust the other valves. * mark the valves you have adjusted.
* if you have still some valves left rotate and make it loose i think this will help you somewhat.

Does Any one know the valve tappets clearances on a Renault megane 1.6e rt?
If it is the 8 valve engine then ensure you adjust them when the engine is cold. inlet- 0.10mm-0.15mm, exhaust 0.25mm - 0.30mm. if it is the 16 valve engine then the valves are hydraulic. DONT KNOW WHO HAS TOLD YOU THAT ABOUT THE 16V BUT THEY ARE NOT HYDRAULIC THEY ARE ADJUSTABLE

How can you adjust the valve height on a 1998 Toyota Camry?
Toyota uses shims to adjust valves. Basically you have to remove the valve, take out the shim measure compare with what it's supposed to be. If it's too short replace with the right height. One shim costs about $8-10 at Toyota dealers. You can get it only from dealers.
What is the tappets settings for a Morris minor 1000?
The correct tappet setting for a Minor 1000, is .012", or twelve thousandths of an inch. The best way to check them is one at a time, to the "rule of nine". This is where the valve open, and the opposite one to be checked, add up to nine. eg, front valve is number one, and if this one is down (open), then you check the gap on the rear valve which is number 8. So 1+8=9. Continue with 2+7, 3+6 etc. There will be two valves open at a time, and I would check the two opposites, but if you are unsure, stick to one at a time.

Is your fiat punto a 8 valve or a 16 valve?
it's a 16 valve, 2 cambeltdriven camshafts
When did they change from 8 valve to 16 valve?
simply to get more power I "believe" that 1991 was the first year for the 16v. I have a 1990, and mine is an 8 valve. Hope this helps. -Tony
Is a idle air control valve adjustable?
Yes the idle air control valve is adjustable. usually set to a measurment based off what make and model your vehicle is. for example most chevy's are to be set around 1 1/8 inch. Once set is should adjust itself as needed. If not replace it.
How do you adjust tappets?
Hey Dave==This does apply to the 305 since it is a chev engine. A 301 is a PONT engine and they have stops for the adjusting nuts. The 350 and 305 have hydraulic lifters and adjust as follows: Pull the coil wire so the engine won' start and bump the engine until the valves on #1 cylinder are both closed. Now turn the engine so the timing mark is on TDC. Adjust the following valves: INT 1-2-5-7 EX 1-3-4-8 Then turn the engine one turn so now it is firing on #6 cyl and adjust the folowing valves: INT 3-4-6-8 EXH 2-5-6-7 . When adjusting the valves, loosten the adjusting nut intil there is clearance between the rocker arm and valve end. Then tighten it just until there is no clearance{you can feel this if you turn the push rod while you tighten the nut} then turn the nut 3/4 turn MORE. This will compress the valve and the lifter will compensate. You can adjust them with the engine running but the oil goes EVEYWHERE and sometimes catches on fire. GoodluckJoe
If the car is not running how do you adjust the valves on a 1971 Chevelle 350 v-8?
Best bet is to look it up in the Chilton's manual. On ALL cams (solid or hydraulic) you make SURE the valve is closed before adjusting. For hydraulic lifters, loosen the rocker arm. Spin the pushrod with your fingers as you tighten it back down. As soon as all of the lash is removed (the pushrod will stop spinning freely) tighten another 1/4 to 1/2 turn. Solid lifter cams require a feeler gauge. If cam specs are unknown, 26-28 thousandths lash cold should work fine. Nearly ALL 350's had hydraulic lifters from the factory. The LT-1 is the ONLY exception. To tell if a valve is closed, slowly turn the engine and watch the valve. For example, when the intake valve for #1 is FULLY open, the exhaust valve is obviously FULLY closed, so you can adjust the exhaust valve. The Chilton's manual will actually tell you what valved to adjust at #1 TDC, which ones to adjust after 1/2 crankshaft turn, etc. But you CAN do it without the manual if you make sure the valve you adjust is closed when the other valve for the same cylinder is FULLY open. Remember, during overlap BOTH valves are open at the same time, even if they are only slightly open. This holds true for ALL 4 stroke internal combustion engines except for the Wankel rotary engine Mazda uses for the RX-7 and RX-8. This adjustment method will work for all of them as long as you know for sure that the valve you are adjusting IS fully closed, and naturally what type of camshaft/lifters are installed. From #1 TDC you can adjust 1,2,5,&7 intakes, and 1,3,4,&8 exhausts. Rotate the engine 1 revolution for #6 TDC, and do the rest. As previously mentioned, this information is well documented in a Chilton's or Motor's manual.
Why does your 307 v-8 stall at idle?
possible egr valve...exhaust gas valve.....
