ur good in theory but not practical


Do u know how to change gasket

Alvin007:
What about cylinder cover seals, valve seals..and pulley seals..etc

TRYGO:
Nice writeup Sir!

I think all what you've discussed are some of the external causes.

But it would behoove you to note that internal oil leaks are somewhat masked by the externals, as you've highlighted.

*** If you've got a worn out valve stem/guides, and valves, you'd notice leaks too.

***piston rings not at advanced stage of wear and tear, would such leaks.

In some cases, its not visible, as the externals you've talked about, but you'd notice excessive oil shortages as time goes on.

EgunMogaji:
Okay so the first gasket you shown is incorrect. That is the cylinder head gasket. If that is keaking then the car won't run. If the car won't run then no oil leak.

The one you wanted to list is the valve cover gasket.

That one is a notorious leaker especially on V and H engine engine configurations.

GAZZUZZ:


im happy somone noticed.

EgunMogaji:


Yeah.

Also if one forgot to remove the old oil filter gasket and install a new filter with gasket what you'll get is instantaneous quarts of oil on the floor and not a leak.

Ask me how I know. Or not.

you have experience nah

Oil seals.....they expands over the time due to heat. In fact those seals are devil, as you are replacing one another one need your attention few months later

erico2k2:

which of the oil seals ? There are up to 50 oil seals in some cars

AutoReportNG:
If your car is leaking oil, this is not something to ignore. Besides leaving stains on the pavement, an oil leak can even pose a fire risk for your car’s engine. If you see signs of leaking, it’s best to get an oil leak fix as soon as possible. Consider the most common reasons for car oil leaks.

Degraded Engine Gasket

The most common cause of oil leaks occurs when the gasket, which is a seal that joins two metal components in the engine, breaks down. This occurs because oil creates sludge over time, which is harmful to the gasket.

Oil Pan Damage

The underside of the oil pan can become damaged due to running over debris in the road, like large rocks. Such occurrences can dent the oil pan, and this can cause the seal to become loose and the oil to leak.

Oil Drain Plug

The oil drain plug is located at the base of the oil pan. When it becomes worn out or is loosened from running over debris in the road, a leak will occur. Fresh oil around the plug is an indication of a leak, as is dripping.

Oil Filler Cap

If the filler cap, which covers the engine oil compartment, is loose, broken or missing, the oil is likely to spill out while the vehicle is running, and it will continue to drip after the car is stopped.

Oil Filter

Oil filters wear out or become loose or misaligned over time. The oil filter is used to remove carbon and other impurities created by the combustion process. This filter is subject to oil pressure supplied by the oil pump and will leak if the filter is loose or the seal from the old oil filter is still on the block which can surface well after the oil change has been done. Use a flashlight check the oil filter for a leak and remove or tighten the filter and recheck. Wipe the area clean and recheck the leak after a short time.

Bad Back Oil Seal. This is oil seal around the crank shaft.
The oil leaks between the transmission and the engine.
You need to bring down the transmission to fix this oil leakage
