SOURCE: slite oil leak from rear valve cover gasket per dealer $650.00

Hello. Let me try to assist you the best I can, with the hope of achieving a FixYa rating from you for my assistance.

Changing the rear valve cover gasket on your vehicle would be not considered a "real" big job, but IS a time-consuming job.
In order to remove the rear cover, you first have to remove the intake plenum. If you do not remove the plenum, you can't get to the valve cover bolts that are under the plenum. After the plenum is off, the valve cover is easy to access. You will also need to replace the intake plenum gasket, if you do the job yourself.

I hope this information has satisfied your question.
Thanks for choosing FixYa for assistance!

SOURCE: pressure return hose repair for 1997 toyota corolla

no need to bleed it at all,just turn steering from left to right and its bled.never done one but it depends on whats involved and what you need to remove to get at it.Also over the pond anything thats not come from motor city they dont know how?? to do it.Just like in europe if its american with auto box then its telephone numbers.Dont be scared just get a new pipe and allow a saturday morning to change it but make sure you borrow a set of pipe spanners first,like a ring with a **** in the end so you dont round off the nuts.Think they are either 16mm or 17mm heads.

Why over reving in idle?

too much air can be caused by binding throttle cable/linkage try disconnecting it. Next would be cold air bypass that lets extra air in for cold weather and initial startup. It would be located on the throttle body
with 2 wires that operate a solenoid. These become gummed up and can be cleaned with carburetor cleaner. Next the EGR valve on the intake manifold could be leaking. Check for cracks or leaks and sometimes the base it mounts to is plastic and wears out. Lastly is the dreaded vacuum leak. There are so many places and hoses to check that I would need to see for myself. The larger hose can go to power booster for brakes. Intake manifold gasket can also leak due to worn gasket.

High idle, after driving a bit when stop idle lopes then high

It is usually caused by the air leakage in the intake manifold. Check the following:
1. Check all the vacuum hoses from around the throttle body.
2. Under the throttle body there are three rubber hoses. Two pipes are of the same size and are used for the coolant circulation through the idle air control valve and the third one is a bit thicker than the two. It is used as the air release tube for the idle air control valve, (if the valve is separate from the throttle body). If the idle air control valve is separate type, it is attached to the side of the surge tank, other wise it is fixed to under the throttle body with Philips type screws (4 mm) as a single unit.
3. To locate the intake air leaking source, take a vacant mineral water bottle, fill it with tap water, make a small hole on the cap with a bag sewing needle, invert it and spray water by pressing the bottle with little pressure and pointing it towards a suspected area. If there is any air leaking from around the intake manifold it will produce an audible suction noise. Locate the area and fix it.
4. Remove the idle air control valve, clean and free it up and install it back.

it's two little hoses in on the left part of the engine running towards the front. You probably need to replace them and put refrigerant back in. not soemthing you can do by yourself.

I have a 1991 Toyota Corolla and I don't know what is wrong with my fuel hose, it leaks when I make a right, and when I fill the tank to a point. And I can't locate the problem, all there is, is a stench...

you need to get your car to a car shop so they can put it on a lift to see what is wrong. fuel leak can be very dangerous.
there is a fuel pump gasket on the top of the tank
there is a filler hose goes to the side of the tank
there are a pressure hose and a return hose go to the top of the tank
there are evaporation hoses on top of the tank as well.
rubber hoses are getting old and crack easily
so there are many possibiltities that can cause leak
