I have a small leak (drip coming from under inspection plate)that i cannot pinpoint is this repairable?

Is the fuel actually leaking to the ground or do you just smell fuel? If it's actually leaking, then you need to determine what is in area where the leak occurs and carefully inspect everything above that area. If you're not quite sure where under the vehicle the leak is coming from, place a piece of paper or cardboard under the parked truck and wait for the drip, then look up from that same area while wearing safety glasses at a minimum. If you just smell fuel but don't actually see a leak, then try to determine if the smell is stronger from the front or rear of the vehicle. If stronger in the rear, it could be a rust hole in the fuel filler tube, a hole in the fuel tank, a rusty fuel line, etc.

There are also combustible gas leak detectors which could help you pinpoint the source of the leak if you are patient enough and the leak is not too large. You'd want to use that with the vehicle parked outside though so there is plenty of air circulating around and underneath the truck.

If the car is an automatic, it will have a thin metal flex plate, rather than a regular flywheel. If the flexplate gets a crack in it, it would cause a bit of noise. See if there is an inspection plate on bottom front of transaxle. Remove the inspection cover to look at the flex plate. Turn the engine over to view the flexplate all around. Look for cracks, maybe a loose or missing mounting nut where torque converter mounts on flex plate. If you see nothing, leave the inspection cover off, and run the engine and listen closely for a problem from that area.
Leaking oil, eh? Don't know if related, but while looking at the flexplate, check if motor oil is leaking out the rear main crankshaft seal. It will be fitted to the rear engine block, in front of the flex plate. Oil would be dripping off the rear of engine, or maybe collecting at bottom of bell housing, evident when inspection cover is removed.

ait may be as simple as a cracked hose, but you will probably have to drop the tank to see what is causing it-you don't mention what make, model and year vehicle but many cars have an inspection plate under the rear seat so that you can make repairs without dropping the gas tank.

Well first make sure you oil level is correct and your in the safe level, Take a look at the oil filter is it leaking there or just tighen it, then check the oil drain plug is it tight and is it leaking there it may need a oil drain plug gasket. you also need to look at the oil sending unit they can leak also. and how long ago did you change the oil oil filter do come loose sometimes

You just blew a hose. Let it cool down, locate leak and replace that hose & refill w/ 50-50 mix of coolant(antifreeze) and water.

Most of the time when I see coolant leaking at the rear/top of the 3400 engine, beneath the throttle plate area, it's usually coming from the intake gaskets. There is a coolant cross-over passage at the rear of both heads and as time passes the gasket will sometimes split along the sides of this passage and coolant will begin to leak out. It can be tough to see clearly whats going on in this area well enough to pinpoint the exact source of the leak so it may take a bit of time to find it. Often with an intake gasket leak the coolant will puddle on top of the block then drip down the rear side of the engine and drip off of the pan or transmission bell housing. Hope this helps you find your problem!

clean it off & inspect for a valve cover gasket leak, a head gasket is possible but unlikely. Use a flashlight & an adjustable inspection mirror (don't buy the cheap small one) to observe for the leak. if that fails you, then go to the local parts store & buy some Brake Cleaner, Florescent Oil Leak detector additive, and a lamp kit for UV dye diagnosis. use the Brake cleaner on all suspect/dirty surfaces, place additive in the engine oil, start engine turn on light & place glass'es on face, look for leak, ID & repair,, recheck work

There is a leak in the line itself. This happens over time from road grime. You can repair this yourself quite easily once you pinpoint exactly where the leak starts. Hope this helps.

Leaks are tough to pinpoint, as the cooling fan and road speed spread fluid all over the place. If u smell antifreeze in the car, the heater core may be bad (leaking). Do your windows fog up, and the defroster makes it worse? If so, the heater core needs to be replaced. As far as under the hood, get a small mirror at a parts store (they have an extending handle to get into tight spots), look under the water pump, at the center of the shaft. There is a small weep hole there, when the pump is shot, it will leak there, and u should be able to see evidence of it. Any other leaks (hoses or radiator) u can check by jacking up the car, put it on safety stands, block all wheels, go under the car w/ a rag (engine off) wipe up any drips, start car, watch for drips forming and dropping from hoses, etc.

the plate is called the inspection plate it is for the trans but my truck is leaking diesel fuel and it runs down onto that plate there is a recal for the fuel leak
