SOURCE: rattling noise from engine sometimes . mostly when

Its probably the automatic cam chain tensioner. Honda told me to ignore the noise because nothing bad is happening. My bike shop said I should replace it with a manual tensioner. I have 15300 miles and will leave it be.

Any chance the valve spring has collapsed? Cam shaft thrust washers missing? Cam shaft bearing gone bad?

SOURCE: Honda CB Seven Fifty 1992. Sudden engine noise

I am not familiar with every engine Honda builds, I don't know what a alternator chain is. Normally the cam chain is quiet. You say it runs so it can't be too out of adjustment. If you wish to keep this bike in mint condition, I suggest you have this fixed by a Honda Pro before the condition worsens.

I have a Kawasaki GPX 600R there's some noise coming from the cam chain. Someone told me that a few gentle bangs on the tensioner would fix it. Is this true or its better to change the tension

how many miles, if cam chain they are about 80 quid maybe less or more, and this needs to be donwe right mate, or bent valves, it could be tensioner if low miles, so a billet one on ebay. they bolt on at the rear of the engine, low down the barrels external. a billet tensioner is about 50 quid, I might know someone who can make one, he does my suzuki ones, where are you. us uk?

I am trying to determine if the adjustment bolt located below the carbs between the second and third cylinders is for setting the cam chain tension and how to set it . There is some cam chain noise at low...

Yes, it is the cam chain tensioner. With the engine off, just loosen the tensioner lock bolt then strongly tap a few times on the tensioner casing with a screwdriver handle. This will free up the spring loaded tensioner. Now just re=tighten the tensioner lock bolt and you're done. Please rate my answer. Thanks. tombones49_157.gif

I own a 2004 BMW R1200CL. Almost every time I crank the engine I can hear the valves rattle. I have checked and adjusted the valve clearances to spec. The rattle goes away after the engine starts, but...

Yep, most of these bikes do rattle on startup. The noise is from cam chain slack. A hydraulic tensioner is used in the engine on each side as there are two cam chains. The tensioner leaks down after the engine sits for a while and the chain rattles for a few seconds till the tensioner gets pumped back full of oil again. Once the chain is tight again, then no noise.

BMW came out with an improved tensioner (doesn't leak down as quickly) that you can install on your engine to fix the rattle. Note that it is much easier to change the RHS tensioner than the LHS one.

Good Luck!

2003 HD Roadglide, stock TC88 engine. HD just replaced the cam chain tensioners with new HD camplate and high flow oil pump. first 2 miles had highpitched noise, metal on metal sound then was quiet. now...

Hi Roadglidetas, no it is not normal, HD is incorrect, your new oil pump and or cam plate could have been defective from the factory.
I would take it back to the dealer and insist politely they fix the noise. If they start dancing around the issue and say it's something unrelated to your upgrade and will cost you big bucks contact Harley Davidson Motor Company directly and express your concerns. I was a technician for 35 years and used to work for the Motor Company it isn't right. Good luck

I have a Mitsubishi Pajero NM 2002 3.2lt diesel timing chain

I checked out the pajero forum, they don't mention the bottom tensioner as being the noise maker here but rather a sloppy chain, stretched beyond the tensioner and riding on the guides. The noise sounds like it comes from the fan area as a metallic chattering. They sell a chain that has a master link in it, and you don't have to tear down the entire engine again to get to it, just the top cover,, Cut the old chain, and use it to pull the new one through. Also, if your chain did jump its gear, it would only be a matter of 8 - 10 miles before the cam breaks. Hope this helps.

Engine knock noise on cold startup

these 3.3l engines are equipped with timing chains. if vehicle has prolonged down time, typically more than 4 hours, vehicle makes a chatter until the timing chain tensioners put tension on the chain. you will need them replaced.

The Jaguar v8 does not have a rocker arm or push rods, this is an overhead cam type engine.
4 cams on top of the heads which are driven by the timing chains, which are driven off the crank.
If your noise appears from the lower end, the most common issue is a main bearing in which case the car will need an engine. (the bearings go bad due to lack of oil circulation, the oil pick up tube in the oil pan gets clogged)
If the noise is upper and the car seems to run rough then the upper timing chain tensioner has broken and the chain has jumped causing the timing to be off.
If you start the car and you have a bad upper noise then the chain could be broken and by running the car you definitely will have valve damage.
