Sounds like you've overfilled the oil. The stick has two marks on it. The top mark is 'FULL HOT" and the lower mark is 'FULL COLD". If you changed the oil filter, you add three quarts of oil. If you did not change the filter, you only put 2.7 quarts in the tank. The next time the cap blows off, as long as the oil level is above the lower mark, do not add anymore oil and see what happens. As long as the oil level is between the marks, do not add oil. Sportsters are notorious for this. People check the oil before they go riding and "top it off". Bad move. As long as the oil is between the lines when cold, ride the bike to warm it up, and then maybe add a bit if it's low. Do not bring it up to the top line even if the engine is warm. About half way is good enough.

Good Luck

Chain oilpump clogged

You haven't stated the make and model, but it's a relatively simple process to access the oil pump and blow out with an air-line. Also make sure your oil tank is empty, remove the oil cap and blow through the main oil line back into the tank.. This can then be flushed out.

I used compressor 3 wks ago and worked great.Now will not compress air above 25 psi.changed regulator OK,removed air intake filter,it has suchion.removed outlet tube,bloweds air.Oil in site glass.I did...


If you have air blowing out of the oil filler cap, I would suspect that the piston rings are shot. The piston rings are supposed to keep the compressed air above the piston, and air seems to be leaking past the piston rings into the crank case.

2005 Harley Sportster Custom , oil tank cap leaks until tank is half a quart low ,could o-ring need replaced it is loose .

If the tank cap is loose, you need to get a new seal or simply replace the entire cap. There are two marks on the dipstick. The upper mark is "FULL HOT" and the lower mark is "FULL COLD". Do not add oil to the tank when the oil is cold. As long as there is oil on the stick, ride the bike until it comes to operating temp and then add any oil if it needs any. This is a common mistake on the Sportsters. If you bring the oil up to the top mark when cold, it'll expand and blow the tank cap out and make a big mess. Do not overfill the tank but if the tank cap is loose, replace it.

Good Luck

NEED TO KNOW HOW TO CHANGE ALL OILS 2005 Electra glied classes harley

The oil tank is on the bottom of the transmission. The engine oil drain plug is on the left front corner of the oil tank. Drain the oil, change the oil filter, and refill with three quarts of any approved 20W50 weight engine oil. Check the oil level using the dip stick. The dip stick is located on the right side of the transmission. The oil cap is a large cap (2" or 50mm in diameter) with knurled edges on it. The dipstich has two marks on it. The top mark is 'FULL HOT" and the lower mark is "FULL COLD". Keep the oil level between these two marks. Check the oil level with the bike on the side stand.

My coolant reservor tanks keeps blowing up. This is my 2nd one to put on today. What is wrong?

Are you running coolant or water? The tank should not blow up, I didn't think it was a sealed unit, but, either you are creating too much pressure, too hot, or the cap is not holding the pressure. The thermostat ,even if it was open, would not build up pressure. But I would get the coolant out of there and refresh it with 50/50, or add straight coolant to the top. Check the cap, keep an eye on the temp gauge, make sure t doesn't over heat, check for steam coming out the exhaust. Water in the oil, stuff like that, anything out of place. Hope this helps.

How to change oil pan gasket . 2003 wide glide

The oil pan is on the bottom of the transmission on your Dyna Wide Glide. To change the gasket start by draining the engine oil and transmission lubricant by removing both plugs on the bottom. Once drained, disconnect the hoses going to the oil pan. Remove oil fill cap, remove two screws and remove the oil spout, pull up on the dip stick cover to remove it. Now, remove the allen head bolts and remove the oil pan. Replace gasket and all bolts. Torque all bolts to 7-9 foot pounds. Refill with oil. Transmission take 20-24 ounces of transmission lube and the oil tank takes 2 quarts 14 ounces of oil if you did not replace the oil filter. Since the oil filter is still full of oil, if you put the full three quarts of oil in the tank, the oil cap will blow off when the oil gets hot as it's overfilled. Good luck

Coolant coming out of reserve tank

In most cases like this, especially if the car is overheting in the meantime and you have white puffy smoke coming out of the tail pipe, it's a sure sign of a bad head gasket or worse...A cracked head.

I say this only if you notice that the reserve tank keeps filling up and building pressure. What's happening, is there is actual engine blow-by pumping its gasses into the cooling system. The result is what you might see there. The reserve tank fills up and the coolant (what's left of it) seeps and gets sucked into the combustion chamber and gets burned with the fuel. (Well, "steamed" would be a better term there....)

Again, IF that is the case, also look at your oil dipstick and the top of the oil cap. Do the stick and / or the underside of the cap look milky? That's another sign of your vehicle in need of some head work.

Considering the cost and labor involved, I sincerely hope that isn't the case! But just to be sure, those are some things you can check for.

Good luck and I hope this helps! :)
