Your motorcycle has hydraulic lifters that run off of oil pressure. Your valves never need adjusting. Now the problem, the hydraulic piston assembly that operates the individual valve can go bad . This will cause a loud clacking or clicking sound. If you have several bad lifters it sounds like your engine is full of marbles. Early models in 1983 had quite a few lifters that needed to be replaced. The Honda dealer knows how to test individual lifters to see if they are worn and need to be replaced. One other possibility, you could have a bad cam chain tensioner . That can cause an even clatter/clicking sound and can usually be installed through the top of the motor

How do i adjust valves pm 4.7 power tech engine


They are hydraulic lifters and should never make noise. You may have a damaged camshaft (flat spot) of a leaking lifter. Not changing oil enough or using inferior oil can allow sludge and varnish to build up until ---click-clack

I have a 2008 civic that started making a tapping noise. It was low on oil. After adding oil, the tapping did not cease. Runs great, but noisy. Any thoughts?


A quart or 2 low shouldn't cause any problems or noises. You need to determine what part of the engine the noise is coming from, does it need a valve adjustment? Is the noise rhythmic, or is it random?

How can i get my tappets fixed


its okay to drive it until you get it fixed next week.they can perform a valve adjustment which will improve or eleminate the valve noise(tappet noise)some of these are done by using a feeler gage and loosening a lock nut and turning a screw adjustment until the proper clearance is obtained and some are adjusted by replacing a shim that sits on top of the valve lifter.

Ticking noise on a Yamaha motorcycle


Most likely what you are hearing is a slightly loose rocker arm clicking when it contacts the valve. Even when they are adjusted properly they can make some noise - depending on the condition of the engine oil and the temperature of the engine. You might look into having your valve clearance checked and adjusted. Change your oil if you haven't recently and you might consider running a heavier, synthetic oil - especially if you have more than maybe 30,000 miles on the engine.

Realistically, you should have the valve clearance checked/adjusted every 15,000 miles and you oil changed every 4,000-5,000 miles max for synthetic oils, less for conventional oils.

My bike is making a clicking noise in the engine near the exaust pipes whenever i excelerate. What could be the problem?


A clicking noise in that area of the engine is most likley an indicator that your valves are in need of adjustment. The valve train parts wear over time and need adjusted because of the excess clearance that results. Check your manual for the procedure to make these adjustments.

My rockerarms are loose on my 2.2liter engine. how can i adjust them?


Adjust the valves when the lifter is on the base circle of a camshaft lobe:
  1. Crank the engine until the mark on the crankshaft pulley lines up with the O mark on the timing tab. Make sure that the engine is in the No. 1 firing position. Place your fingers on the No. 1 rocker arms as the mark on the crank pulley comes near the O mark. If the valves are not moving, the engine is in the No. 1 firing position. If the valves move, the engine is in the No. 4 firing position; rotate the engine one complete revolution and it will be in the No. 1 position.
  2. When the engine is in the No. 1 firing position, adjust the following valves: Exhaust - 1,3 Intake - 1,2
  3. Back the adjusting nut out until lash can be felt at the pushrod, then turn the nut until all lash is removed (this can be determined by rotating the pushrod while turning the adjusting nut). When all lash has been removed, turn the nut in 1 1 / 2 additional turns, this will center the lifter plunger.
  4. Crank the engine one complete revolution until the timing tab and the O mark are again in alignment. Now the engine is in the No. 4 firing position. Adjust the following valves: Exhaust - 2,4 Intake - 3,4

My 1992 dodge stealth rt has a clacking noise from engine when running .we have determine the noise is comming from the lash adjusters.what should we do .


The lash adjusters are hydraulic and will have to be replaced. They can be replaced without removing the head, you just have to remove the necessry intake & parts that restrict your access to removing the valve covers, then remove the rockers (that's where the adjusters are of course), replace the adjusters and reassemble. Make sure you note the direction of everything, once reassembled it should fit exactly as it did before, with a little less slack.

All engine parts like this need oil. Soak the valve lash adjusters in oil overnight before installing, preferably in a warm location, or place a warm light next to the container you put them in, they work like valve lifters, just smaller.

Good luck

2000 astro has intermittent clicking noise from engine compartment


The clicking noise emanates from the clicking of the
valves, and tappet hammers, under the valve cover.
If these are noisy, it means that it need to be adjusted
for the proper clearances and retightened. Have these
items checked to completely solve your problem. These
valves when properly adjusted will give your car good
mileage.
