Question about Ford Thunderbird

1 Answer

I have a 1979 ford 302 that i have changed the valve cover gaskets, intake gaskets, rear mail seal, oil pan, and just installed a one piece oil pan gasket. I still have a leak at the rear of the engine. It seems to drip out of the bell housing and I just can't figure it out. Any suggestions? The motor came from a 1979 thunder bird with an automatic trans. I have installed it in a 1963 ford fairlane with a borg warner t-10 four speed.

My 2004 ford freestar runs well but is leaking about a quart of oil a week almost


If it's leaking from inside the engine then it would be coming from the valve cover. The cover gasket seal is no longer sealing properly. If oil is leaking down under the car then check around the oil pan, could be gasket or rear main oil seal or front oil seal.

Oil leak on driveway coming from front of engine


Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

  • The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.
  • External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.
  • Engine oil leaks at the distributor can be misdiagnosed as leaks from theintake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.
  • If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.
  • Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
  • Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

    1992 Ford Crown Victoria Oil Pan is leaking. Is this a major problem to replace? Fred


    It is recommended that you lift out the engine before attempting to replace the oil pan. Once the engine is lifted you can remove the bolts, remove the pan, clean all the old gasket material.
    Installation: Remove the rear main bearing cap oil seal Remove the timing cover oil seal Clean all the mating surfaces and seal grooves Install new oil pan front cover seals Install a new rear main bearing cap oil seal Install new oil pan side gaskets on the block Make sure the tabs of the front and rear seal fit properly as these are critical spots Attach the oil pan to the engine block and install the retaining bolts

    I have 1995 toyota camry with 2.2 liter engine.I installed a new oil pan gasket,and valve cover gasket,cause there was alot of oil leaking from that area.All the work was done about two months ago.there...


    I have the same car and the same problem. I can see the oil shooting out at the (upside down) rear, right side of the oil pan. This side of the oil pan is covered by a piece of plastic foam. There are no bolts on this side of the pan. Toyota recommends grey Formagaskit to seal the pan. The natural flow for this leak is all over the bell housing. The piece of plastic foam is attached to bell housing inspection cover. Good Luck!!!

    My rear oil seal went out


    The rear of the oil pan can in some cases leak into the bellhousing area, be picked up by the flexplate and thrown around. Also, make sure that your pcv system is working and that you are not building pressure in the crankcase. If you are building pressure, it can force the rear main oil seal to leak.
    good luck

    1984 F150 302 Had oil pan gasket and both valve cover gaskets


    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!

    1987 ford ranger 2.9 leaking oil


    Hello, this is probaly your rear main seal on the back of your crankshaft. I would check and see if it is a two piece or a one piece main seal. You sound like a knowledable mechanic so this would not be to heard if you have taken a oil pan gasket off a ranger. I have a ranger and did an oil pan in a parking lot without jacking it up and removing the motor and shock like the manual says so I know that takes some skill. So, look up the seal in your Haynes or Chilton Auto Manual and I would replace this seal. Oil near your starter and the back of the oil pan is a classic sign of a rear main seal. Now, to get the seal in out you can refer to your manual and just remember to torque your rear main bearing cap to the proper torque when your done and also try to clean the bottom of your oil sump screen while your down there that would be a benefit later on. A tip to get a stuck seal out is to take an old wire tester the one that looks like an ice pick; this can push out a stuck rear oil seal very easily. I hope this helps your problem and I wish you the best of luck. If you have any other questions just email me ok.
