Engine oil leak on bottom side of motor when driving down the road an not at idal? its not the oil pan gasket just replaced it.

If this has the v6, it's probably the intake manifold gaskets. This is a super common problem with these. You end getting oil in the cooling system and anti-freeze in the oil, they also leak externally when this happens. I would get it looked at/repaired asap or severe engine damage will result. I've had to replace quite a few over the years.

the head gasket is on the engine higher than the oil pan so if the leak is not were the head meets the cylinder block and running down towards the bottom of the motor then the head gasket is not the problem.if the leak is only around the oil pan area and slightly above it then its probably the oil pan that is leaking.fluid leaks travel backwards or downwards not up.

• Hi, for oil to leak that fast you have got a massive leak. The ticking itself could be from low oil. First check the oil plug (where you drain the oil) on the oil pan with will be the bottom most part of the engine. It is possible the plug is not holding tight, the gasket may be old, torn or just plain missing. Sometimes people will strip them oil plugs. When this happens the pan has to be tapped a little over and a new, slightly oil plug installed.

• On the oil filter housing are oil cooler line that have to hold a lot of pressure. Follow those lines to see if they are leaking oil.

• I don't see a front seal leaking leaking quite that bad. A valve cover I am not sure would leak quite like that either. Your oil pan gasket could leak like this though. When you check the oil pan plug look strait up to all them little bolt holding the oil pan to the lower part of the engine. If leaking is noted then snug them bolts up or have them snugged up.

• You may have to throw a piece of cardboard on the ground and crawl underneath with a flashlight and get a better eyeball on the leak. What ever the leak it is massive and should be repaired before driving or you could loose to much oil and seize your engine. The ticking. in my opinion, is the engine telling you it is very low on oil as it is.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

There are three other area's that can leak, here they are in order of how often they occur
1.Engine Valve cover gasket(s) (2 if V6 engine), oil runs down the engine and drips off the pan.
2.Rear crankshaft seal leaking
3.Front crankshaft seal leaking. Oil is blown back by air pressure while driving and rips off of pan.

Could be the gasket for the whole oil pan that's leaking. That would let oil run down the oil pan, to where the drain plug is.

1. timing cover is leaking oil betwwen cover and block
   
2. Disconnect the negative battery cable.
   
3. Remove the drive belt(s), fan and fan shroud. If equipped, remove the accessory drive belt pulley.
   
4. Remove the vibration damper retaining bolt and washer. Remove the vibration damper using a suitable puller.
   
5. Remove the accessory drive brackets attached to the timing cover.
   
6. Remove the A/C compressor, if equipped, and alternator bracket from the cylinder head and move to one side.
   
7. Remove the oil pan-to-timing case cover bolts and the cover-to-cylinder block bolts.
   
8. Remove the timing case cover front seal and gasket from the engine.
   
9. Cut off the oil pan side gasket end tabs and oil pan front seal tabs flush with the front face of the cylinder block. Remove the gasket tabs.
   
10. Clean the timing case cover, oil pan and cylinder block gasket surfaces.
    
11. Remove the crankshaft seal oil seal from the cover by prying it out with a suitable tool.
    

To install:

1. Install a new seal in the timing cover using a suitable seal installation tool.
   
2. Apply sealer to both sides of the replacement cover gasket and position the gasket on the cylinder block. Cut the end tabs off the replacement oil pan gasket corresponding to those cut off the original gasket. Attach the end tabs to the oil pan with sealer.
   
3. Coat the front cover seal end tab recesses generously with sealer and position the seal on the timing cover.
   
4. Apply engine oil to the seal-oil pan contact surface, then position the cover on the cylinder block.
   
5. Insert timing case cover alignment tool J22248 or equivalent, in the crankshaft opening. Install the cover-to-cylinder block bolts and tighten them to 62 inch lbs. (7 Nm). Install and tighten the oil pan-to-cover bolts to 11 ft. lbs. (13 Nm).
   
6. Remove the cover alignment tool and position a replacement oil seal on the tool with the seal lip facing outward. Apply a light coat of sealer to the seal and a light coat of oil to the crankshaft. Install the seal on the timing cover.
   
7. Apply a light film of oil to the vibration damper hub seal contact surface. Install the vibration damper using a suitable installation tool.
   

Do not hammer the damper into place as damage may result to the damper or engine.

1. Install and tighten the crankshaft vibration damper bolt to 80 ft. lbs. (108 Nm).
   
2. If equipped, install the crankshaft pulley and tighten the bolts to 20 ft. lbs. (27 Nm).
   
3. Install the accessory brackets.
   
4. Install the fan and fan shroud.
   
5. Install the drive belt(s) and adjust to the proper tension.
   
6. Connect the negative battery cable.
   
7. Start the engine and check for leaks

HI. This may be a oil pan gasket issue. The gasket is facing downward towards the ground, so the leaking oil in this area would not necessarily touch the enigne block. It would actually run down the sides of the bottom section of the oil pan and the rim areas. Also; make sure that it is indeed engien oil. It may be transmission fluid or power sterring fluid, as well. Raise the vehicle or slide under the frame to take a closer look at the oil and transmissin pans to locate the actual leak point.

In most cases of this nature, it will be either the transmission pan gasket or oil pan gasket that will be the culprit.

Could be the oil pan gasket or the rear main oil seal.
Remove the torque convertor cover. ( I am assuming that your truck is an automatic) That's that thin metal cover between the engine and transmission on the bottom side.
Drive the truck around the block to warm up and the oil to start leaking.
With the engine running in neutral, emergency brake on and wheels choked for safety.
Crawl under the truck and see where exactly the leak is. Is it between the flywheel and the engine block --leaking straight down the center of the flywheel --crankshaft rear seal?Or the pan gasket? or even a oil galley plug?
Good Luck.

you have several points to check!
the dip stick tube has a "O" ring seal at the bottom where it fits to tranny.
a reverse switch on tranny & the shifters selector shaft has a seal that may be leaking !
there are the cooler pipes from cooler to tranny [in & out] plus pump seal to the torque converter [leaks out between engine & tranny bellhousing] & then there are the drive shaft or shafts seals
so wipe it all clean & park it in a diffrent clean spot!
some will only leak when its runnung due to tranny,s internal pressure!
