Question about 2005 Ford Freestar

1 Answer

It is just a slow leak and the oil pan gasket or oil drain plug is not leaking so I think it is the front seal.

It could be the front main seal or the front engine cover seal. I would degrease the area in suspect and try to pinpoint the leak. Good Luck

SOURCE: Leaking oil pan gasket

Check the pan to make sure it is not cracked or warped. Also notice where most of the leak is coming from. When you took off the old gasket, did you scrape off all of the old material? If you used a screwdriver to do that, you may have nicked the metal and created a path for oil to leak. If you didn't scrape off the old material and any RTV sealant, you will want to, using a plastic scraper. There are sprays that dissolve this material too if it is too hard to scrape off.

If that area is nicked badly and you haven't used RTV sealant, you may want to put a small amount all over the area that the gasket will cover, not just the nicked area but the whole area that the pan gasket will cover- it doesn't take much and if you smear too much on, it will just ooze out and make things messy - just a fine coating will do.

As you tighten up the bolts, make sure you tighten in an alternating pattern as they begin to contact the gasket and get tight so a bolt on one side get fastened down as often as one on the other side gets fastened to avoid warping the pan.

Hope this helps.

Could possibly be the pan gasket. The other things that may be your leak would be the rear main seal or the front crank seal. If the oil is coming out from the rear of the oil pan then it is most likely the rear main seal. If you have high mileage on the vehicle in excess of 100,000 miles this becomes even more of a possibility. The front crank seal will leak at the back side of the crankshaft pulley and blow back towards the rear of the engine. I would vebntire to say it probably is the rear main. To replace the rear main you will need to remove the tranny and the flywheel and then the retaining plate for the rear main seal. Unfortunately Ford went to the one piece deal years ago. If you need more assistance please feel free to ask any questions you may have. We are all here to help you with all questions. Good luck.

SOURCE: How to diagnose an oil pan leak

The ford ranger and the mazda b series have the same problem with oil leaking at the pan gasket. When you are under the truck, look on the side of the block between the pan and the block toward the middle of the pan and if you see oil gathering or running back then you have the pan leak. Look at the bottom of the trans bell housing to see if oil is gathering at the bottom. If so look at the side where the trans and block join and see if oil is leaving residue there If it is an auto you can remove the sheild and see if oil is inside the cover. Just a hint, If the rear main is leaking there will be oil all in the cover, if not then pan leak is main issue. Either way the trans may have to come out to pull pan back. Now I hav done the job many many times at the mazda dealer and never removed the pan. If you need more advice just ask

Sounds like the valve cover gasket, clean off all the oil on the engine with a pressure washer or a steam cleaner and then drive it and recheck for the leak, that way you can pin it down for sure.

Oil leak can be attributed to several factors.
1. Gasket failure.
2. Uncontrolled Crank case pressure Failure.

RECOMENDATION:
Tighten both the valve cover and oil pan bolts.
Replace the Positive Crankcase Ventilation Valve and vacuum line.,

INFO: PCV
This is a valve causes a negative vacuum on the engine while its running, As to say if it had a leak in a valve cover it should not be leaking while its running, only when the engine it turned off.

Hope this tip guides you in the correct direction to solve this problem.

Oil leak on a '92 Geo Tracker. Installed an O Ring, but still leaking. Any suggestions?


O-ring where? The drain plug? Distributor shaft? Or do you mean oil seal?
Geo oil drain plug specifies a compressible copper ring washer I think? Need to clean the surfaces well, and torque to spec. My own plug's seal is not perfect, but only a drop here and there usually. Autozone or NAPA can supply you a new plug and washer if needed.

Oil leak between oil pan and transmission.


Try running some of that high-mileage engine oil next time you do an oil change (it helps to swell engine seals slightly). If the problem clears up or is reduced, then it's likely that the rear main oil seal is starting to leak a little. The rubber seals will harden up and shrink a little with age.
I would also powerwash the entire area clean, so that way any leak will be easier to monitor and pinpoint.

Having an oil leak at the bottom of my camry, not the oil pan gasket what else could it be.


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.

My Chevy 2002 Tahoe is leaking oil. They told me


this truck is equipped with an aluminum oil pan you could have 1 or several things going on... a stripped drain plug which is causing it to leak or it may be a leaking front seal or a rear main seal. If it is a front seal it is not to labor intensive. But if it is a rear main seal leaking it will require the transmission to be removed since the seal is a 1 piece rear main
