The recess that the spark plug goes in,is quite deep.In order to get any water etc. out,that drainage hole has been put in.Its good that its not blocked.The oil coming out can only come from the valve cover,on top of the motor.Its only the gasket that is leaking.It needs to be lifted,cleaned and reinstalled.As you rev the motor,more oil is pumped around the motor creating extra oil coming out that hole.With the tank off,look down beside the spark plug and you will see it will have the oil in the sparkplug recess.The hole is in no way connected to the inside off the motor.It is purely a drainage hole for the s/plug recess.Hope this helps

Hesitates under load, idles fine


Usually this problem is caused by a misfire. First check to see if all of your spark plug wires are pushed on tight. If that is not the problem, look at all of your spark plugs. If they are fine, get a volt meter and test all of your spark plug wires.


In my case, I washed the engine and some water got into one of the spark plug holes. We blew it out with an air compressor and my car was good as new!

Fix seized engine


White smoke is an indication of water in the engine. Like when you see a car with white smoke from the exhaust on a cold morning, it's heat moisture condensate in the exhaust (normal), and is being heated and converted to steam as the engine blows hot exhaust out. To test if it's water in the engine, there are two likely indications, (1) the motor oil will be milky and white, or (2) you can remove the spark plug and see if any cylinder sprays water mist when the engine is turned over. In either case the problem is a bad gasket, maybe head gasket (repairable), or a cracked block (big $$$ fix). If engine will not turn over, there could be two causes (assuming the battery and starting system is good); (1) a cylinder is full of water and hydraulically locked keeping the engine from turning over (removing spark plugs should relieve the pressure and allow you to turn the engine over (* you'll see mist or water coming out spark plug holes), or (2) the engine is seized, therefore the previous troubleshooting is unnecessary, engine replacement is necessary. Best of luck resolving this problem.

Hi, I have a Convair TRB portable air conditioner and I dont have an instruction manual. I'm wondering about the drainage outlets on the rear of the unit. The top one (half way down) has a black tube...


No the bottom hole should not be plugged. the bottom hole is the drain for the condensation. If you plug that hole the water will fill up and damage the unit.

I went through a huge puddel and the car stoped and the engine wont spin


Sounds like there is water in the engine. First check the oil level, if it is over full you have water in the crankcase and will need to drain the water form the oil pan. Next you will need to remove all of the spark plugs because it sounds like it is hydrolocked. with the spark plugs removed spin the motor over with the starter and after a bit of that, most of the water should have cleared form the cylinders. once you get it running, go over all of your fluids looking for anything overfull, indicating water intrusion and change anything suspect.

Continuous drainage


Take out the drain pan and look in left hand top of the compartment and you will see a drain hole for the pan.Plug the drain hole with a small rubber plug, I used an electrical wire nut wrapped with tape and it worked fine.replace the pan and the water will run out the back. A 3/4" garden hose should work for the drain hole.

My 2004 was mini was missing sporadically, like bad gas. I occured a couple of times and quit over the course of 3 or 4 days. Finally, it worsened and is not getting hot. Also, it is losing coolant,but no...


There are a lot of "could be" issues from what you described. Worst case, a blown head-gasket. Coolant will leak into the cylinder bores and flood the engine. You can't see the coolant loss, and the engine is misfire.

You can easily check this by removing 1) ignition coil wires, and 2) spark plugs. Make sure your spark plug wires are not around metal (so they don't arc weld your engine), or totally remove the distributor cap. Have someone crank the engine over while you watch the spark plug holes (which are empty, since you removed the plugs) and see if any water sprays out of the holes. You can use a rag or paper towel to catch the spray. Look for green fluid (anti-freeze), or greyish water (oil + watch mixed together).

If you see either of these,DO NOT START THE CAR. Immediately take the car to a dealer or machine shop to change the head gasket (best case) or rebuild the block (worst case).

Tiller has sat in weater for a year. I changed the spark plug, and found there was water or gas in the oil (lots of it) i drained the oil and put in fresh but now it wont even start. what is my problem or...


You need a few things for a combustion engine to work. Firstly you are going to need to know a little about engines and how they work.
Fuel - try draining the tank and putting fresh fuel in it - fues does go stale. This will include fuel in the carburetor so that needs drained too. There was liquid, assuming water in the oil, perhaps it is in the fuel too.
Fire - do you get a spark to the spark plug? Pull the plug out and see if you get spark when trying to start - remember the earth of the spark plug needs to be touching the grounded metal such as the engine or frame. Perhaps the electricals have been water damaged.
Air - clean out the air filter and surrounds.
You have already drained the oil and replaced it - good start.
Maybe something has corroded since it has been in the weather for so long.
If it still does not want to start, try pulling out the plug & trying to start - is anything spitting out the spark plug hole? If so, what?
Once that is clean and clear and it still doesn't start but you have spark, try putting a bit of fuel carefully in the plug hole, say half a tablespoon.
How does that go?

After washing engine bay with water car wont start has no spark


The water leaks down into the spark plug holes. Remove the coil packs and spark plug wires, and sop up all the water in the spark plug hole. Leave the plugs in so water does not get into the engine. dry out the wires with an air gun, or just let dry. when everything is totally dry, put everything together and start.
