Question about Pontiac Fiero

1 Answer

I am leaking ENGINE oil on the passenger's side of what appears to be the extension unit the automatic transmission, where the axel half-shaft mounts. There is one large bolt on the front top side of this case extension (13mm) and one small bolt on under this bolt near the bottom of this extention (10mm). What's going on? It only drips oil when the engine is running, and it is a lot of oil! I had to put 6 quarts in it to drive 20 miles home!

Hi


Thanks for using FixYa. First of all please remove the cover of camshaft and clean the surfaces and apply some RTV sealant and replace the plate again to avoid the oil leak. Even if you are using a gasket even then use RTV sealant to seal it properly. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

    Rylee,


    Please note, the oil is not dripping from the timing gear cover, which is the crankshaft/camshaft cover on the front (passenger's side) of the engine. (It's a 4CYL - 2.5L4 engine). It is coming from the transmission extension that the half-shaft inserts into.


    UPDATE!!!!!!!


    I just went back out and looked at it again to make sure the information I was giving you was accurate. The area I have been talking about has an "L" shaped mounting bracket that bolts the transmission extension to the engine. However above and slightly forward of that is the oil pressure sending switch. It appears that it is leaking and this allows the oil to flow down the side of the engine block, onto the bracket, which then allows the oil to flow down the extension to the bottom where it drips off. Does this make sense to you?


    It appears to be the oil pressure sending switch, it's not loose in the block, so can it leak otherwise?

Camry csi 2000 oil leak between engine and transmission


Lots of Camrys do this.

The oil will typically leak from the rear main bearing seal between engine and transmission, but that will appear at the bottom of the joint line, and will not reach the exhaust. This leak is expensive to fix and is usually left as is.

A leak from the cam cover gasket can drip into the exhaust.

The other typical leak is from the distributor shaft o-ring seal. This appears at the top of the join line between engine and trans, and can blow back onto the exhaust.

2003 Ford Escape transmission leak. 175 K miles. Tranny rebuilt at 120 K miles. It appears to be leaking where the tranny bolts to the engine. I've checked the axels and transmission pan and all...


This is quite tricky, the oil leak can be only due to a failure of the OIl seal or that the bearings after being worn out can damage the oil sealing.
So it is best that the unit be taken out in the engine side to be probed.
Now since the leak is more when the engine runs it is better to take down the unit for an overhaul , confirm and then replace the seal / bearings.

2001 mitsubishi eclipse gt spyder clutch removal. how do you get the axles out and how do you release the bearing for the tranmission to seperate


After the axel is removed from the outher wheel bearingf( seaparate the steering knuckle from the lower ball joint) and pull the axel out of the bearing after the axel nut has been removed then the axel will pry ou tof the transmission.. Might take a strong pry witht he haelp of a hammer. the one side might have a carrier bearing on the CV axel that bolted to the back of the engine block. It'll have to be unbolted. too. the starter will have to be removed also as all the bolts that hold the engine to the transmission.

There is a popping sound coming from the front end of my car when I accelerate but only when my car is moving, not when it is parked. Any ideas?


Sounds like your half shafts are going bad. Does it make this noise when turning left or right? If it does your half shafts have gone bad.

Leaking oil left side of motor


Since it's not clear whether you mean driver side or passenger side, I will address both.

On the driver side, the most common leak is from the distributor. This can be caused by the distributor shaft exterior o-ring, or it can be caused by the distributor shaft interior bearing seal. To determine which it is, remove the distributor. First detach the spark plug wires, then undo the bolt that holds the distributor to the head, then pull the distributor out of the head. You will see the o-ring on the exterior of the distributor shaft. This is a $0.50 part, so just replace it with a new one as long as you have the distributor out. The bearing seal is on the inside of the distributor. To inspect it, undo the three bolts holding the cap to the distributor body. Pop the rotor off the shaft, the unclip the inside plastic cover. If you see any oil inside the distributor or the distributor cap, this means the seal is leaking and must be replaced. You can get a seal and bearing replacement kit from kbox.ca. Or, you can just buy a new distributor. Note: To get the distributor back in place you must align the shaft correctly with the notch in the camshaft. There is a right way and a wrong way. If the shaft seems to be aligned but does not go in, pull it out and rotate it 180 degrees, then put it back in.

The other possibility on the driver side of the engine is the main seal between the engine and transmission. If this is the case, you would have to either drop the transmission or pull the engine to replace it.

What if the oil is leaking on the passenger side? If it's coming from behind the timing belt cover, there is a camshaft seal and a crankshaft seal, both of which can leak oil. To get to them, you will have to remove all accessory belts and the alternator, remove the exterior crankshaft pulley, remove the engine mount (support the engine) and the timing belt covers, remove the timing belt, then the crankshaft pulley and/or camshaft pulley, whichever is necessary to replace the leaking seal(s).

Where else could oil be leaking from? If it's coming out from near the top of the engine, that's the valve cover gasket. Remove the valve cover and replace the gasket. While you're at it, replace the spark plug tube seals.

If it's coming out from near the bottom of the engine, it could be the oil pan gasket. Remove the oil pan and replace the gasket.

One more possibility for oil leakage: The head gasket. But in this case you would have noticed other symptoms besides just an oil leak.

Good luck! Let us know how it turns out.

LEAKING FRONT AXIL SEAL


take the wheel off , unbolt caliper and sling it out of the way with a bungi cord, take off the rotor, then you have too take the pumpkin cover off the axel diff in the front (drain fluid first) easy way to do that take out bottom and side bolts out then leave top 1 or 2 in but finger loose. pry cover off with a sturdy scrapper from side allowing fluid to leak out from bottom of cover. when fluid is done comeing out then take off cover. to take the axel out to replace the seal you have to push the axel inwards to remove the C- CLIP on the end of the axel shaft that slides into the inside of the pinion gear (use a extending magnet) keeps gear oil on your hands and from dropping it into the pumpkin housing. then all you have to do is slide the axel shaft out. then replace the seal .
