First of all don't put the power stearing stop leak fluid in. It just softens the seals making them swell which temporarily semi stops leaks but gives you one big leak after a while any place there are seals. If the guys who rebuilt your engine didn't have a check the seals and bolt torque check that's wrong. Then unless you have ripped holes in your transmissions bottom I don't see replacing the covers if that's what they are talking about. If they are leaking just take a wrench to them and don't tighten too tight. If you change an automatic trans filter there is sometimes a gasket for the pan. The oil pan gasket is cheap also. The cheapest quick garage for a car is pulling one side up on the curb, set the parking brake and block the tires. I'd figure buying the repair manual and parts and all the work after stops at a parts store would be under $100-$200. But then I don't know how much an EGR valve is.

knowledge is power. learn to do as much as you can, and when you do need to farm out the labor to a shop who thinks that you are just an ignorant woman, you can put them in their place and save a few bucks. the best way to learn is to hang out with people who know what's what. there are a lot of folks on here from Cali that would be more than happy to help out a fellow Chevy enthusiast in need, without the usual reasons guys help women work on cars, if you know what i mean. if i wasn't up here in MN, i would try to help you out for little or no repayment. i just like working on cars.

Thats quite a bit of money for an EGR Valve job. I replaced my EGR valve on my 76 camaro and spent $50 for the egr valve, plus some sealer and a gasket which was a few dollars. The EGR or Emission Gas Regulator, sits on the intake manifold, and was fairly easy to change out. The tranny pan on the other hand is not too hard, but can be messy and take longer, A gasket set can be had for 12 dollars with the filter and gasket. They are trying to make money on labor probably. I would call other places and ask around about the time needed to install an egr valve or tranny pan gasket and price per hour. I took about 20 minutes to change my EGR Valve, and about 1 hour to change the tranny pan gasket and filter. Good luck, hope this helps

The EGR valve on that IROC, assuming it has TPI, is under the intake manifold plenum box, and it definitely isn't a 20 minute install!!

Having run a large shop, I can tell you that: If ya don't know how to fix your own car, then your gonna be at the mercy of the people that can. This doesn't mean that everyone is out to screw you, but this is how they make their living, and the only guy who knows what was included in the estimate is the guy who wrote it. If your not happy with the estimate, drag the car to the guy down the road and get a second opinion.

As for the cost, and affording it, the saying around our shop was: "we fix cars, not lives"!

Money Pit! This car is 14 or 15 years old and some stuff is gonna break. I owned an '85 IROC new, and the monthly payments were almost as much as what this repair is gonna cost. Cars aren't free to own!

BTW, EGR stands for Exhaust Gas Recirculation.

egr stands for Exhaust Gas Recirculation. It's technical definition is "it decreases flame temperature by reducing oxides of nitrogen", or in lamens terms, it takes nitro out of the exhaust and puts it back in the cylinder. sometimes, the valve itself is'nt bad, just dirty with carbon and can be cleaned with a $2 can of carb cleaner. i'm not saying that is what the problem is, but it is feasible. sometimes, these mechanics will tell you, in your case, the valve itself is bad when it could only be a disconnected vaccum hose at the EGR solenoid. they get the extra money because a TPI EGR valve job is about a 2 or 3 hour job. at $50 an hour, it adds up quick when they actually only spent 5 seconds on it reconnecting the hose. i'm not saying that is what all mechanics do, but it is not uncommon. as for the power steering, without a decent knowledge of this system, tackling the problem is hard to do. i hope you find someone who can fix your car, or you do it yourself, but if you have any questions, ask us. someone on this site will know the answer. good luck!

Your pretty close but this is the way that the EGR system works:

Nitrogen is generally considered inert in that it doesn't get "reacted" or "burned" in the combustion process. When combustion temperatures are extremely high, as in modern engines, some of the nitrogen in the intake air does get "reacted" and forms harmful, ozone depleting oxides of nitrogen. The EGR system introduces a small amount of exhaust gas to dilute the incoming air fuel mixture. This makes the combustion slightly less efficient, but reduces the combustion temperature to the point where the nitrogen doesn't get "reacted". This makes the EPA happy!

Don't forget that on old cars the EGR valves actuator diaphragm sometimes rips requiring replacement of the valve. Also, if I were to spend 3 hours replacing that valve, I would bang in a brand new one for $50 to prevent having to eat the whole job as a "come back" a month later.

just my $.02

Wow, I sounded like kind of an a$$ in those last two posts!

Appologies in advance, didn't mean to sound like a jerk but I think I did!
