SOURCE: 1999 VULCAN HAS OIL LEAKING

hi, sounds like the oil seal in the rocker cover has failed, remove the rocker cover and you will see a rubber seal, this seals the oil inside the cover, however when the seal fails around the spark plug hole, oil leaks into spark plug well and out of weep hole.

Reconed dyna no4c turbo enjin strugles to start and white smoke


White smoke is usually steam vapor. You may have a head gasket leak or a cracked head or block that is allowing water to seep into one or more cylinders. If water is in a cylinder it makes it hard for the piston to compress it before the exhaust valves open to expel it into the exhaust system. Water in the exhaust is then heated to steam vapor. Check to see if you have any water in the engine oil.
Water in the oil is often associated with the above situation.

Take compressed air and blow air up into the the weep hole. For some odd reason it made 3 different CRF's stop leaking. It's worth a shot.

VOLVO V50 OIL ON CAMSHAFT COVER


I will try and simplify the problem. I have an oil leak, which I traced up the back of the engine to the cylinder head area.
When I removed the top plastic cover on top of the coil packs I found oil in every recess next to the coil packs. The crankcase breather pipe was also off. The source of the leak is not evident, but it is definetely above the cylinder head gasket area.

Water is leaking from the drivers side as soon as you fill it with out the car being on it is a 1988 Honda civic dx hatch back


There is something called a "weep hole" on the water pump. Water seeps out of this hole to let you know the water pump is bad. It is to the lower right of your driver's side motor mount right below the head, but it's on the side of the block. From the bottom you will notice this leaking all over your lower plastic timing cover. When you change this pump you are also supposed to have your timing belt changed.

Water is leaking above water pump against block but i can not see. i reveved up car now when i put water in just comes right out but i cant see behind the water pump in the upper area is ther a hose behind...


could be the weep hole located on back of water pump right on top if its leaking its probably pissing out if this is the case its time to replace the hoses are on both sides but sounds like if u cant see and its behind pump its the weep hole try using a small mechanics mirror to take a peak with engine off you should see a antifreeze water mark indicating the leak

Anti freeze driping out of seep hole from the bottom of case


hello
there are two different seals on the water pump. the oil seal and the mechanical seal. the oil seal helps seal out the oil from the trans case. the mechanical seal helps seal the coolant from going into the trans case, and vise versa.
the weep hole is there to help diagnose if either seal is faulting. so if coolant is leaking from the weep hole. the mechanical seal is faulting or if the oil seal is leaking oil will drip from the weep hole.
hope this is of some help. thank you.

1999 VW Jetta:it uses a whole can of anti freeze every other week


either the water pump is bad and water is leaking out of the weep hole on the bottom of the water pump while the engine is running OR you have a blown head gasket that is letting coolant seep into a cylinder and it is being burned by the engine. Have another car follow you on the highway while doing about 60 MPH or 100KPH and then floor the gas on the car and see if the car following you can see any smoke or mist looking exhaust coming from your car. If they do see mist or smoke coming from your exhaust, you most likely have a blown head gasket that is allowing coolant to be burnt by a cylinder.

If you can't afford to repair the car at this time, if you keep your eye on the coolant level and refill it when it needs coolant, you could continue to drive the car until you save the money for the proper repair.

Much good luck.
