Question about Yamaha V Star Custom Motorcycles

1 Answer

I just had valves adjusted at 14,000 miles and the lifter noise is still present at 55-70 miles per hour. I am running AMS OIL Synthetic 10/40. Is this common for this noise?

    This 1100 Vstar Custom has solid lifters so Yamaha recommends the lifters get checked for adjustment every 4K miles.

No, it's not. Try using a thicker oil -  20/50 -  and if the noise is still there then you have some worn out parts. Take the camshaft cover off and check every single valve and lifter for play.

Mitsubishi l200 2.5 did 08 very noisy engine, sounds very tappety is this normal ?


It may be worn out valve lifters that are inside the engine. If you have more than 6,000 miles on the oil, valve lifters could run noisier. Changing to a high mileage type of motor oil may quite down the valve lifters noise somewhat. Synthetic oil used during the summer months could make it noisier too. If you can hear the noise while driving the car, it is not normal. Upon acceleration, if it gets noisier, you will be needing a valve job in the not to distant future.

What can I do to eliminate lifter noise in my 1994 Nissan pathfinder? It just started making the noise about 2 weeks ago. Is it adjustable? Should I use synthetic oil, thicker oil?


The VG30E engine has hydraulic valve lifters so there is no adjustment possible. You can try replacing the oil and filter, substituting one quart of ATF for one quart of oil. Let it go for 3,000 miles and do it again if necessary. If after the third time the tapping is still there, you will need to replace the hydraulic lifters.

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.

Top of the engine is ticking. friend told me it could be a valve that is clogged or stuck open and thats its not a huge problem but it might be mixing gas and oil. to me that sounds like a problme....


It sounds like hydraulic lifter noise. The lifters open and shut the valves and can be helped by using a good synthetic oil and frequent oil changes. Lash is the clearance between the valves and lifters.

I have a big twin Harley. I use synthetic oil in the engine. I ride about 14,000 miles per year. I live in WI How often should I change oil.


It really a question about comfortability. Some folks change their oil(s) every 5000 miles (or more), some every 2500/3000 miles and some might do it as often as every 1000 miles. Depending upon the model year of your bike current H-D specifications recommend changing the engine oil, transmission fluid, and primary chain case oils every 5000 miles whether using conventional or synthetic fluids.

Upper end engine clicking or clanking noise heard. Car runs and has power but is making this noise.143k miles v-6 4.0 sohc. What could this be?


Could be cam chain tensioner, valve lifter.
Add "motor medic" to oil in a warm engine.
The increased viscosity will push harder on the cam chain tensioner....if that is the issue.

Clean oil - better quality (synthetic) oil will clean a clogged lifter.

I have 1997 chevy Z-71 sometimes on startup the engine makes a knocking sound for about 3 seconds and goes away. I dont know if I have a major problem or not can you help?


I think it is normal for these vehicles. My '97 Tahoe did it also and I'd heard it was normal and not to be worried about. Kind of sucks but I had 150,000 miles on mine and it was fine.

Good luck.

I don't know if the noise from my 2003 vw tdi is normal. Are there any valve adjustments that need to be made on this engine (1.9)? My car has 160,000 miles on it. It's not too clattery, but more so upon...


There's no tappets adjustment needed for this engine as they are hydraulic lifters. Try using 10w40 instead and see what happens or otherwise try using Moreys oil treatment with your current oil as it seems to me that the noise is more at startup and for a short period. Cheers.

Valve tick on one cylinder that tick intermitenly,thicker oil


There was a "Silent Recall" for this problem. Basically the heads, lifters, and cam are all replaced. I had this fixed under the recall on 1995 Pathfinder when it had 44,000 miles on it. Now it has 175,000 and has been had the cold engine noise since 145,000. The ticking is more irritating that it is harmful (Per my mechanic). I don't want to stick 1,000's of dollars into it anymore, tolerance is much cheaper.

Valve Lifter Noise on 2001 525.


The Castrol synthetic 5W20 oil may be too light for your car. None of the following three sources recommend 5W20 oil.

Per Bentley manual for 1999 and later E39 BMW (excluding M5), BMW HP 5W30 synthetic oil (07 51 0 017 866) is recommended.
Per the Mobil Oil web site, Mobil 1 synthetic 0W40 oil is recommended.
Per the Castrol Oil web site:
SM 5W-30 - Thank you for inquiring about what oil is best for your vehicle. Based on the information you provided, your vehicle requires a special engine oil that can only be purchased at your local dealer. Please visit your local dealer to ensure that your vehicle is serviced properly.

Does the noise vary or is it constant? Noticed only at startup or all the time?
Another ticking noise source could be the VANOS unit.
