Stop The Oil Leaks

Does anyone know how to stop a shovel from leaking oil? New member here but far from a new rider (scoots didn't have engines when I started riding). I just had my 78 FLH rebuilt. Before the rebuild I had one spot of oil under her

I know very unusual. Now the dam thing leaks all over the place and the guy that rebuilt it tells me to GFM. Alas what am I to do? Besides shooting him!If possible, find out where the spot of oil is coming from. That will give you a clue on what to fix. I rebuilt a few Shovels, so I know a bit about making them leak free,,,

After changing new piston rings, Oil consumption starts.

You must always gone the bore when replacing rings. Not only does it allow the rings and bores to seal perfectly, it also removes the burnt on none stick oil coating that is preventing your new rings from bedding in. Given time the smoking should stop.

Could also be worn or leaking valve guides allowing oil past the valve stems. They are leaking when cold but seal when they warm up and expand.

Oil leak from vent pipe only after driving

Part of the engine's compression is getting past the piston rings and going into the crankcase. The crankcase is letting the compression out via the vent pipe as it should. A little bit of the oil splashing around in the transmission is being carried into the vent hose by the compression. The vent pipe is leaking onto the roadway soon after you start to ride ( as the revs increase ), you just didn't know it until now. When you stop riding, the oil that is still in the pipe is what leaks onto your driveway. Your bike is big enough that you don't notice any loss in power. The repair is a bit expensive; new pistons, rings, boring the cylinders, a valve job (since you already have the head pulled off, now is a good time to do it ), and the labor charge. Unless the leak is really offending you, I would just park the bike in a spot where the oil won't stain the concrete and leave my money in the bank.

You didn't give me much information. If it's not from the engine, the only other thing on the bike that has oil in it is either an oil line or the oil tank. Sportsters are notorious for developing a leak on the backside of the oil tank, If you take the battery out and look at the bracket that comes from the oil tank to the battery tray, you may find your leak.

If the oil tank is leaking, purchase a new tank. I saw one guy try to stop the leak by coating the tank with "Creme" fuel tank coating. It did stop the leak but after a while the heat from the oil turned the coating brittle and it chipped off and stopped up his oil pump.

Good Luck

Where is the transmission oil serviced

Run the Low Rider's motor for a few minutes to warm the oil up. Shut off the bike.
  • 2 Find your Low Rider's drain plug (on the oil pan). Using the screwdriver, loosen then remove the drain plug, and drain the oil into the drain pan.
  • 3 Remove the Low Rider's dipstick.
  • 4 Let the oil drain completely.
  • 5 Clean the drain plug threads with a clean cloth or paper towel, apply sealant, and replace the oil plug and dipstick.
  • 6 Move the drain pan to beneath the oil filter. Using the oil filter wrench, remove the oil filter.
  • 7 Discard the filter in the pan with the old oil. It is full of oil.
  • 8 With a clean rag or paper towel, clean the area where the gasket meets the motor.
  • 9 With a clean finger, rub a bit of new oil on the gasket of the new oil filter before installing it.
  • 10 Install the new filter, turning until snug, then turn it by hand another 1/2 turn. Take care to not over-tighten, as this will damage the filter gasket or the filter, possibly causing the Low Rider to fail.
  • 11 Open the oil reservoir, using the funnel; fill the tank with the fresh oil and close the reservoir.
  • 12 Run the motor for a few moments to coat the engine with the new oil. Check for leaks. (If you find any, check the filter and drain plug for a tight fit.)
  • 13 If there are no leaks, after the motor has run for a few minutes, turn off the motor and check the oil level. Top it off if necessary.

  • hope this helps

    I have a 1985 harley davidson low rider that i have not run in several months. when i tried to crank it oil poured out of the breather. why does this happen and what do i need to do to fix it

    This is typical of a lot of Harleys. This is what we refer to the enigne "puking" oil. The reason it does this is that the engine has been sitting for a long period of time. The oil tank is located higher in the frame than the oil pump on the side of the engine. There is a check ball in the oil pump but sometimes it doesn't stop the oil from seeping past and getting into the cam chest of the engine. When this happens, there is more oil in the cam chest than the oil pump can pump out quickly. So, some of it is blown out the crankcase vent and winds up where ever the vent hose terminates, either in the air filter or on the ground.

    To fix the problem, you'll need to "reseat" the check ball and install a new one. I've seen it done before with varying results. The best thing to do is not allow the bike to set for long periods of time. If you're not going to ride it, at least come out and start the engine about once a week to keep the oil pumped into the tank.

    Good Luck

    My 1980 Harley FLT shovel head is making louder then normal sounds and seams to get hot. I think maybe oil pump?

    Shovel head lifters tend to wear out. Check your adjustment first. Shovels also run on the warm side. Does it idle good? If not, check for intake leaks.

    How to change oil on a 2003 Kawasaki Vulcan 750 motorcycle? Where is the oil pan plug?

    Firstly run your engine till you reach its normal running temp .The engine drain plug will be found under neath the engine normally at the lowest part .Warm oil drains out of the engine much more quickly that cold oil ..when all the oil stops dripping then remove the oil filter ,make sure that the sealing ring is removed ,take care the oil in the filter will be very hot .replace with your new filter make sure you do not cross thread the oil filter unit and any seals have been fitted . Refit your drain plug and fill up to the required level . start engine ,your oil level will drop because the oil filter will fill up and the new oil will be pumped around the engine. make sure that the engine level is topped up when all the oil has reached all the parts of the engine .Do not over fill the engine as this will cause unwanted pressure .and oil leaks .Remember to replace the oil filler cap and that its tight .

    My engine oil light is on, and my bike wont stop reving

    hmmm tricky.... knackered fuel tap sounds favourite, petrol vapour coming back round the system via breather back in to airbox making the revs go up, and probably oil is like water being mixed with petrol that's been leaking through. take of oil filler cap and smell oil, if it stinks of petrol, drain oil, if like water and full of petrol, change fuel tap, oil filter, and refill with new oil. carb float valves should stop petrol seeping through in theory but it'll always get past. just thought, if it is all that then airfilter will be full of petrol vapour as well, get a new one if paper, wash out if foam.

    What type of motor oil used in 1994 harley davidson 883

    harley recomends that you use their oil but i would be carefull because it is a cynthetic now if you were using regular oil what that will do is clean all the old build up out of the motor this can be bad because after time there are pin hole leaks that occure but the build up stops it from leaking but if you use cynthetic you cant go back to regular oil it will gum up on you and ruen your motor so you got to find out what has been put in it. but use a 10-30
