SOURCE: oil around spark plugs on 1992 honda accord

Yes the oil can cause the car to lose spark, the oil leak could be caused by the valve cover gaskets around the spark openings, but 9 times out of 10 it is the spark plug tube "O" rings. The top of the valve train comes off of the head, the "O" rings are between the two halves, that will fix the oil leak.

No spark is uasually caused by a faulty coil or the trigger unit,both are inside the distributor. Get a used distributor fron a scrap yard (about $4o) and replace yours.Remove the dis.cap and turn the engine until the rotor is pointing to fire # 1 cyclinder,and mark the exact position of the base before removing from the block." Do not turn the engine" Install the other Dist. with the base in exactly the same position and the rotor pointing exactly to # 1 cyclinder. Note. Failing to install the other dist.exactly the way you took the first one out will throw the timing out!!!!!
Be doing all of this be sure there is no spark.

SOURCE: Honda GX340 11 Hp ..Runs fine until it gets hot , Cuts off and

FIRST...check the engine oil level. Some Honda engines have an oil sensor that shuts off the spark if the oil is low. This would also explain it shutting down when it get hot. Check the manual to see how to tell if the oil level is correct. Also, the oil should be brown and transparent, not black. It may need changing. Post again if this doesn't help :-)

SOURCE: oil filter in civic 97

If you go to a reputable motor factor,
you can only be sold the correct filter for the civic.
As there are soo many variables in engine type, it's almost impossible to tell, oil volume, or which type filter.
However, I will say, be sure that you don't mix semi-synthetic oil, and mineral oil.
Oil changes should be undertaken every 30,000 miles, (unless under extra work load, (in which case, slightly more regularly))

Otherwise, 10/40 or 15/40 grade oil, is perfectly fine.
The trick to not overfilling the oil, is simply just to take your time, clean the dip stick and retry, until you have the correct reading.

Please don't forget to rate:)

How to change a cars oil.

Changing the oil yourself.

Changing the oil in a personal vehicle is fairly straight forward and easy. The first thing you need to do is to make the underneath of your vehicle accessible. You can do this a few different ways. You can use drive up ramps, a floor jack and jack stands or if you’re lucky enough to have access you can put your vehicle on a lift. No matter what your decision is you must take proper safety measures to keep your vehicle from moving while you are underneath. Always use jack stands and your emergency brake with tire wedges if you are not using a full lift.

Next you need to locate your oil drain plug, which is on the bottom of the oil pan. Remove it and drain the oil into some type of drain pan or bucket. After replacing the oil pan plug locate your oil filter and remove it. Replace the filter and lower your vehicle. Now, remove the oil cap that is at the top of the motor and fill the motor to the recommended level. Start the car after making sure there are not any leaks. After letting the vehicle run for a few moments, shut it off and check the oil level. If everything is OK, then you are done and have just saved your self a few bucks.
An oil change can make a dramatic impact on how your can runs and feels. The difference of a motor with fresh oil and one with old oil is huge. You could compare oil changes to dialysis; oil is your motors blood. When your oil is old and dirty your motor will feel sluggish, like a dialysis patient before their session and it will have to work harder for the results that would have been easy with clean oil. Motor oil affects almost every moving part in a motor. With clean oil everything will run smooth in unison affecting gas mileage and the life of the motor. Most manufactures recommend changing your oil every three thousand miles or if you don’t dive that much every three months, there are manufactures that recommend every five thousand miles but a higher grade and more expensive oil needs to be used.

I have a new Honda GX690 engine. It is the model without the Oil Alert system and is the remote control model. We are having difficulty getting it to run. It will turn over etc but will not fire.

Jeffery, you have answered your own question. First I say, you don't mix and match Honda's. Or most any newer engines and transmission. You bought an engine that didn't a feature from the old one. Even though there are some engines that match, they are out of range from the year. You have to replace the parts and sensors from the old to the new..

Wipers dont work changed wiper motor fuse and still dont work

On a car over 15 years old the odds are the wiper motor failed

You need wiring diagrams to work on electrical

You have to see what is in the circuit you need resolved

No one can tell you how to diagnose things,you follow a
procedure that work for you

Don't change any parts

That is not how you work on a car
Learn how things work & test to confirm failure

Your not going to have relay failures as you read about
on these sites,too much bad info talked up on here

A fuse will blow if the motor or any motor fails,so that could be
a key do not replace a fuse,go to what it controls such a the motor
& try unpluging it & use the wiring diagrams to put power to it

1992 accord oil light blinking. What causes this.

This can be caused by a few things, so lets start with the easiest first. Check your oil level, if the level is low, the light will flash. If that is to no avail, then I would recommend changing your oil, make sure you get some good oil, I would run any Mobil Oil products, and an oil filter. If this does not stop the light from illuminating, then I would recommend that you replace the oil sending unit. This is a switch that screws into the motor and registers your oil pressure. If the switch/sensor is faulty, then it will not give the correct pressure, and that will illuminate the oil light. The sending unit is not expensive and can be picked up at any auto parts store.
