SOURCE: top end engine rattle 1989 sportster

That rattle if its a piston probably is the piston pin.If your piston were making the noise it would get louder and lock up sooner or later I would not run it until its fixed it will tear up your motor.

SOURCE: i have a 2003 twin cam 88, stock, and the rear

The TC88 engine runs typically hotter than the Evolution engine. This due to the EPA's stringent emissions laws. As a result, the engine is running very lean. The best thing you can do is take it somewhere that has an exhaust gas anylizer and have them adjust the fuel mixture. If the bike is carburated, a jet change is required. If it is fuel injected, a change may can be made in the fuel mapping. Call your local dealer and see if they can do this for you. Good Luck.

SOURCE: rattling on top end back cylider

The only thing under the rocker boxes is the rockers and the upper part of the heads with the valve springs. Getting to this area is not that difficult.

Remove the fuel tank and seat. Then, remove the six bolts that holt the top and middle rocker box covers on. Now, you're at the rocker plate with the rocker arms in it. You can also see the tops of the valve springs. Look and see if there is anything that might be causing your noise.

Now, keep in mind that a Harley engine is of an old design. It is a pushrod type engine with rocker arms that open and close the valves. They are going to make a little noise. Now, if you're having to get close to the rocker box to hear the noise, it's probably nothing to worry about. But, if you can hear the noise stand away from the bike a few feet, you may have a problem. But most things that might break or come loose under the rocker box will usually effect the way the engine runs.

Also, you could have an exhaust leak. It makes a "tick, tick, tick" type noise. Tighten the nuts on the two studs snugly but don't break them off.

Good Luck
Steve

I'm still having problem after setting tappets car runs after + - 30k ,makes a tappet noise just one push rod and rocker runs loose but nuts are all tight on the rocker, plz if can advise me regards


Hard to help much without knowing what type of vehicle you are working on, but I would suggest pulling the rocker and making a mark with a sharpie or paint and re-installing everything tight. Run the engine until you get the rattle back, then check the mark to see if the rocker stud is coming out of the head.

At startup the lifters rattle and oil pressure guage will fluctuate between 20-40 at 600 rpm idle for about 5-10 minutes and then quiet down. The oil pressure normally ran around 30-40 and above 40 on...


I suspect that the oil filter is one that doesn't have a anti drain back valve in the base of it needed for hydraulic tappets. have the hydraulic tappets check for a leak down test as they wear and by-pass oil The oil may be to thin for a car of 173.000klms I consider you should be running 30w-50 oil. The cheapest way out is to change the oil and see if it makes a difference.

Intermediate ticking or rattle after about 20 miles of rideing but not all the time dosn't sound like a lifter 20000 miles on 06 dynasuper glyde


Yes, it could be the roller bearing that runs on the cam on the end of a tappet going bad. This is about the right mileage as well from my experiences. If they are going to go bad, they usually do it between 20 and 30 thousand miles although I had one bike lose a tappet roller with only 13 thousand miles on it. If they make it past 30 thousand, they usually last the lifetime of the engine with no problem. I have yet to understand why this happens. These rollers are indeed a weak point in the design of the engines. If you suspect this is the problem, do not run the engine until you check the problem out. If the roller locks up, it will destroy the cam that the tappet is running on because it will damage the cam lobe.

Good Luck

Oil light stay"s on and engine will start to tic


If your oil light is on, and your engine is rattling really bad, I'd load it on a trailer and take it to a dealer. I've seen oil pressure sending units go bad and turn the oil light on but as long as the engine is running normally it's more than likely got oil pressure. However, your engine is equipped with hydraulic tappets. If the engine has no oil pressure, these tappets will clatter noticeably. If in doubt, take it to a dealer and have it checked out. I'd advise trailering it to the dealership.

Good Luck

You will have dry all ignition components ... You have a distributor that you can open? Get a drying agent from your auto parts store (spray can) and spray all high voltage wires. Next sunny day, roll the Vette into the sun and leave the hood open all day.

Hello there. I've recently bought a 54reg mk5 golf 2.0 gt fsi and the engine is making a tapping noise - even when it's been running. Is this normal?


a light tapping noise is quiet normal .Use a flushing oil before you change the oil and filter.then use 10/40 semi synthetic(as recc by VW)when engines at operating temp run at 3500 fo 30 secs,this will "charge" the hydraulic tappets,a cold engine has a valve rattle for about 15/20 secs but if longer then cam followers faulty.normally at 120,000m(roughly)
please leave feedback..

07 street glide,I experenced the tappets rattling like hell a couple days ago while in traffic,but seemed fine a little later what should i expect is something getting ready to go out?


Sounds like an oil pressure problem. If you had one tappet to start rattling, I'd suspect a roller on a tappet was going bad. But you said "tappets", plural. If all your tappets were rattling badly, you lost oil pressure for some reason. This is the only thing that I can think of that will do that.

Good Luck

Runs on "iron dry" no matter what setting i select.

Rattling sound 0-20 mph comes and goes, 6 disc cd changer skips


Howdy,
the rattling sounds like its the hydrolic lifters (tappets or cam followers called also) not really a hard job just a pain cause you've to strip the engine to pieces to do. Its very time consuming so unless you've some experience i'd place this in the hands of an experienced mechanic. This should also stop the smoke problem.

The engine service light is on a timer from service to service so thats nothing to do with it.

The cd player your right about it just need the lazer llens cleaned. You can buy a cd cleaner kit for cheap in any music/record store.

Hope this helps if not let me know and I'll try and find the solution

Cheers
