Question about 1994 Toyota Corolla

1 Answer

Toyota Carina loss of power

The rear engine crankshaft seal and torque converter seal was recently replaced. It started heating up when I reached home. I have replaced the thermostat and fan relays. Now during driving the temp gauge is half way but when the car is stationery it comes abit above the 1/2 mark.
Also when climbing a hill or moving from a stationey position it doesnt have enough power and the engine revs to 3000rpm and starts to be jerky.

Lets start with the heating up problem!
replacing the thermostat and relay has nothing to do with it. common causes of heating up are improper valve setting timing, mismatch air-fuel ratio, worn-out piston rings, poor oil flow, poor radiator coolant flow.
i suppose you have changed your car motor oil. recheck if its on the right amount.


loss of power:
Common Causes
loose piston rings (causing insufficient compression: indications fog like smoke), air-fuel ratio incorrect, blockage in air intake.

check also for air on the fuel hoses if you experience often jurking problems regularly clean fuel strainers or filters.

Crankshaft seal on a 2005 chevy equinox


If you're looking for the seal -have a look on Ebay:
1 042results for equinox crankshaft seal

If your question relates to a leak, a classic symptom of a leaking crankshaft seal is drips of oil from the bell housing - where the transmission attaches to the engine. It only leaks when the engine is running.

To replace the seal you need to remove the transmission/clutch/flywheel assembly -or in the case of auto transmission - the torque converter which attaches to the rear of the engine.

To remove the old seal you simply prise it out with a screwdriver, lubricate the new seal and gently tap it into position. However as mentioned, you need to remove the transmission first..

How does a worn crankshaft bush effect a torque converter


Check the hub. You should inspect the old torque converter you are removing for damage to the converter hub that rides in the pump of the transmission. If you find any wear on the hub at all, you should replace both seal and bushing. If you find no wear at all, you may be fine with just a seal replacement. You should at least do one (seal) if not both. (seal & bushing).

Rear barring an seal replaced


I'm not sure if this is the right part of your car but, are you talking about the rear seal on the engine for the crankshaft?

If so:

Rear Main Oil Seal REMOVAL & INSTALLATION Fig. 1: Rear main seal installation for the 2.3L and 2.5L engines 85553306.gif
Fig. 2: Removing the rear main seal 85553307.gif
Fig. 3: Installing the rear main seal on the 2.9L engines 85553308.gif
If the crankshaft rear oil seal replacement is the only operation being performed, it can be done in the vehicle as detailed in the following procedure. If the oil seal is being replaced in conjunction with a rear main bearing replacement, the engine must be removed from the vehicle and installed on a work stand.
  1. Remove the starter.
  2. Remove the transmission from the vehicle, following the procedures in Section 7.
  3. On a manual shift transmission, remove the pressure plate and cover assembly and the clutch disc following the procedure in Section 7.
  4. Remove the flywheel attaching bolts and remove the flywheel and engine rear cover plate.
  5. Use an awl to punch two holes in the crankshaft rear oil seal. Punch the holes on opposite sides of the crankshaft and just above the bearing cap to cylinder block split line. Install a sheet metal screw in each hole. Use two large screwdrivers or small pry bars and pry against both screws at the same time to remove the crankshaft rear oil seal. It may be necessary to place small blocks of wood against the cylinder block to provide a fulcrum point for the pry bars. Use caution throughout this procedure to avoid scratching or otherwise damaging the crankshaft oil seal surface. To install:
  6. Clean the oil seal recess in the cylinder block and main bearing cap.
  7. Clean, inspect and polish the rear oil seal rubbing surface on the crankshaft. Coat a new oil seal and the crankshaft with a light film of engine oil. Start the seal in the recess with the seal lip facing forward and install it with a seal driver. Keep the tool, T82L-6701-A (4-cyl. engines) or T72C-6165 (6-cyl. engine) straight with the centerline of the crankshaft and install the seal until the tool contacts the cylinder block surface. Remove the tool and inspect the seal to be sure it was not damaged during installation.
  8. Install the engine rear cover plate. Position the flywheel on the crankshaft flange. Coat the threads of the flywheel attaching bolts with oil-resistant sealer and install the bolts. Tighten the bolts in sequence across from each other to the specifications listed in the torque chart in this section.
  9. On a manual shift transmission, install the clutch disc and the pressure plate assembly following the procedure in Section 7.
  10. Install the transmission, following the procedure in Section 7.

My toyota vienta 3VZ-FE 1996 - oil leak onto exhaust


Hi,

That engine will leak oil from

- cam cover gaskets (rear one drips on the exhaust)
- camshaft end seals
- distributor shaft o-ring (appears on top of transaxle housing)
- oil filter bracket to block o-ring seal (drips on front bank exhaust)
- crankshaft nose oil seal (have done with timing belt change)
- rear main seal (expensive, leave it be)

Losing oil form flywheel end of crankshaft. Already changed seal twice but ain't made any difference. any suggestions?


yes , depending on wheter you talking about torque converter seal or rear engine main seal , on trans if your front pump bushing has excessive wear then it will not seal because the torque converter input shaft will ride on seal more than it is supposed to and also it will not run true, also check TC mounting of flex plate if you flex plate is not centered then it will rotate out of balance and cause leaks and pump damage, if you talking about a rear main engine seal you may have a issue with run out and or bearing wear issues cause seal to not be able to do its job, check all those issues, crank shaft end play as well as up and down play and check rotational run out on TC of trans and pump bushing in trans pump... hope this helps, thanks please rate...

Need to do a compression test to see if all 4 cylinders are operating properly. A loss of engine power is usually a result of wear on internal engine rings and seals.
