I need help here, my #2 exhaust port is dripping oil out of it, and I''m not running on more than cylinders 1 and 4 here. whats going on with this thing? I should add that when its running I hear a noise I cannot describe from the exhaust side cam area on the #2 cylinder, that sounds somewhat like a collapsed hydraulic lifter on a car. few of my pilots are damaged badly.

Re: oil dripping out of exhaust port
Need to replace the carb rack or get them completely rebuilt. If cleaning doesnt help, and a few of your pilots are actually damaged to a point where removal is impossible without some manner of special tool you need.

Td4 leaking oil at the manifold to head I'd say u got a worn manifold gasket , as with all turbo diesels there will always be oil in the boost system and nothing to worry about unless it is dripping with oil and if there is oil on the outside u got a leak not just of oil but of boost to
just coz you put youre thumb over the hole and you have compression does not mean that you have good compression find out what the maximum pressure is supposed to be and get a porper compression tool. oil from the exhaust is odd i think this could be v/v guides but it would not explain why exhaust is not getting hot.
I am not a Malaguti expert but your problem sound like a clogged exhaust canister on the header. You probably need a new one. You can make sure of that if you can get your hands on another, even used, one to swap and test.Once you take off the exhaust canister, check the exhaust port on the cylinder if it has reduced diameter from burnt and solidified oil. You need to clean that carefully not to scratch the piston or drop solidified oil into the cylinder. Also check your oil pump (if there is one) to be properly adjusted and not to overfeed the engine with oil. If you mix the oil with the gas in your fuel tank, never exceed 2% oil in the mixture. You do more harm than good.
Fuelleaking from the cap will not stop it running, 40-1 with good quaility two stroke oil shoule be fine, if there is a good spark and fuel at the plug, you need to check that the piston has not picked up, the hottest part of the engine is the exhaust side, so remove the muffler, and take a look at the piston skirt throught the open exhaust port, any signs of scuffing and it will need to come apart to check the damage.
Draining some oil is the thing to do. It will probably take a few days for the dripping to stop. The cylinder walls are splash lubricated. Too much oil lessens the splash. Chances are that little or no damage was done. Install a fresh set of spark plugs. Before installing, compare the spark between 1 & 2 cylinder. If the spark is noticeably weaker on cyl 1, consider getting a new coil. Please rate my answer. Thanks.
You don't " get a cylinder cleaned ". Who ever says that doesn't know what he is talking about. I assume the engine is a two stroke. The gas/oil mixture should be 32 to1. That means 4 ounces of two stroke engine oil to one gallon of gas. If the scooter has an automatic oil pump be sure there is oil in the oil tank. It should automaticly pump the engine oil at the proper rate. If this is an older scooter, you could remove the cylinder head and de-carbon it and then check the exhaust port to be sure the port has not been made smaller due to carbon build up. The port should be about 1/2" tall and 1" wide. Also check and clean the air filter. If it is a new scooter is it still under warranty?
- cam cover gaskets (rear one drips on the exhaust)
- camshaft end seals
- distributor shaft o-ring (appears on top of transaxle housing)
- oil filter bracket to block o-ring seal (drips on front bank exhaust)
- crankshaft nose oil seal (have done with timing belt change)
- rear main seal (expensive, leave it be)
