Clean it all off and dry it and then spray TINACTIN foot powder all over the suspect area and ride the bike and look for the start of the oil leak in the foot spray.

SOURCE: oil leak 2008flstc crank case

Whenever you changed a gasket you should have checked if the barrel top or the other bit on top is leveled.These usually gets deformed just like cars whenever the gasket blows...I am using my experience from cars and motorbike to say this but most of my experience in bikes usually solve this by tightening the barrel screw,as if to lock the combustion chamber better...this usually solve this but if it does not then you need to get them out and check for uneven level and may need to sent to a machine shop to fix this..Hope this helps and please rate this solution..

SOURCE: I have a 1999 sportster 883 it's leaks oil out

Sounds like you're overfilling the oil tank. Always check the oil with the bike on the stand. There are two marks on the oil dipstick. The upper mark is "FULL HOT" and the lower mark is "FULL COLD". Keep the oil level between the two marks and never "top off" the tank when the engine and oil is cold. As long as you see oil on the dipstick, ride the bike until the engine is at full operating temp and the only add oil if it is below the lower mark. Never fill it to the top mark. Your Sportster holds three quarts of oil that is pumped into the engine and then back out. The 1983-1985 XR1000 Sportsters, the hot rod Harleys as they were called, on held two quarts of oil. I've seen hill climbers that had custom oil tanks on them that only held a pint of oil. As long as you can see oil on that dipstick, you have enough oil. If you're getting so much crankcase blow by that your blowing oil out of the tank breather tube, you need to run a compression or leak down test on the engine to check for ring wear. Also, I've seen bikes do that when the needle and seat in the carb was bad or the accelerator pump diaphragm bad. Smell of the oil. Does it smell like gasoline? If so, you have carburetor problems and gasoline is running into your engine diluting the oil and adding volume to it.

Good Luck

What would leak oil onto the starter

the oil leak could be a bad valve cover gasket needing replacement, a head gasket leaking oil, a leaking intake gasket and oil running down along the engine block and dripping. it could be an oil pressure switch that is leaking. it is near the starter while driving or engine running can spray oil onto the starter. unless the oil leak is very bad and has been leaking a long time onto the starter will not cause it to act like a dead battery even then not likely. have a starter draw test down to check condition of the starter.

Oil leak above starter and hits exhaust manifold

Rocker cover gasket must be leaking. Sometimes just tightening the cover bolts will stop it. Otherwise replace the gaskets.

My 2003 Sportster is leaking or pushing oil out air filter, my sportster has chrome rocker box covers but none of the rest of the engine is chrome. My mechanic says he has never seen this before.

Hi Anonymous, if it's leaking from the case seams aside from splitting the cases and resealing them is to check the torque on the case bolts 1/4" bolts/nuts 10 ft lbs. 5/16" bolts/nuts 20 ft lbs. for all other leaks the usual suspects are:
1. Loose parts.
2. Imperfect seal at gaskets, push rod covers, washers ect.
3. Restricted oil return line to oil tank/pan.
4. Restricted breather hose to air cleaner.
5. Restricted oil filter.
6. Oil tank/pan overfilled.
7. Bottom rocker housing gasket installed upside down.
Oil leaking from your air cleaner is caused by oil carryover from the engine. For what ever reason the breather system is not seperating enough oil mist and air from the piston downstroke. There are cheap and quick easy fixes and there are more exspensive ones. Start by trying the following:
1. Run your oil level half way between the add and full mark when hot.
2. Run oil breather lines from head into a TEE fitting below carb/induction module then a single line into a mini filter under frame.
3. Purchase Arlen Ness Super Sucker.
4. Replace umbrella valves and realign oil pump
5. Upgrade oil pump and cam plate
Good luck and have nice day.

I have a Husqavarna LT100 mower (15 years old) It started leaking oil from where the B & S engine is bolted to the frame. I've tightened up the 4 bolts but its still leaking. Any ideas...

Bear in mind that the bolts holding the motor to the frame do not have any oil passages near or through them. The oil is just oozing down the side of the motor and collecting there. If there is a little valve cover near the spark plug(s), the gaskets for these often get hard with age, leak and need replacing. This will be a small door about 2x3 inches with a bolt on the top and bottom, again near the spark plug(s). remove the bolts, take off the cover, clean the old gasket material off the cover and the engine block, put your new gasket on and snug the bolts back up. In the real world this would be a good time to have someone adjust the valve clearances too, given the age. You are not doing that yourself and when I replace that gasket I put some gasket goop on the new one before I put it in. I have a very handy neighbor who is subject to beer bribery and I have him adjust the valve clearances.

Trying to track down oil leak need cutaway to help find possible locations on engine that could leak motor oil

Best is to pressure wash it - then run and inspect it after the run.

If it's at gearbox join - suspect main crank seal
If it's near oil filter - replace gaskets there.
If near cambelt - expect to replace seals behind there.
Or head gasket.

Started leaking oil apparently from top end near oil filter housing ,have replaced ring gasket every oil chnge. still unable to find leak. car has 110,000 km,meticuasly maintained any probables would be...

You will need to clean the area very well and watch for the leak while it's running. Most common leak cause is accidental double gasketing, where the old gasket remained on the filter pad and the new one was installed on top of it. i have also seen (but rarely) an oil filter with a defect in the casing. If your filter is mounted to an extension housing on the block, the gasket there can also leak.
You need to look though. 'Can't fix it if you don't know what it is!!!

I have oil leaking badly from arond were the rockers would be.

You may have nearly blown the head gaskets, causing some oil to leak out of the cylinder heads so the gaskets will need replaced. Don't try to start the engine again as this make the situation worse because it has lost the pressure it needs to work properly. Since this pressure is gone the whole engine is running too fast than it needs to do causing it too get really hot and the heat generated from the engine is escaping from the leaky head gasket also making it become hotter.

I hope this is of some help to you.

1987 ford ranger 2.9 leaking oil

Hello, this is probaly your rear main seal on the back of your crankshaft. I would check and see if it is a two piece or a one piece main seal. You sound like a knowledable mechanic so this would not be to heard if you have taken a oil pan gasket off a ranger. I have a ranger and did an oil pan in a parking lot without jacking it up and removing the motor and shock like the manual says so I know that takes some skill. So, look up the seal in your Haynes or Chilton Auto Manual and I would replace this seal. Oil near your starter and the back of the oil pan is a classic sign of a rear main seal. Now, to get the seal in out you can refer to your manual and just remember to torque your rear main bearing cap to the proper torque when your done and also try to clean the bottom of your oil sump screen while your down there that would be a benefit later on. A tip to get a stuck seal out is to take an old wire tester the one that looks like an ice pick; this can push out a stuck rear oil seal very easily. I hope this helps your problem and I wish you the best of luck. If you have any other questions just email me ok.
