Catalytic Converter

post the readings they gave you.

I put a new cat converter on my '89 240 wagon about 2 years ago. As I recall, it cost around $70 at AutoZone or PepBoys, and the job probably took me an hour or two to do. Have passed our Georgia emissions test twice with no problem, and car running well. Don't see why yours should be so expensive!

State Limit My Car Hydrocarbons: 1.0000 GPM 1.1500 GPM Carbon Monoxide: 20.0000 GPM 9.2548 GPM Oxides of Nitrogen: 2.2000 GPM 4.0865 GPM

This was a re-test on a particularly hot day. My first test only failed the NOx test at ~3.5000 GPM.

Firstly OEM means Original Equipment Manufacture which is to say that the item is made by the same firm as makes the one fitted to your car by the makers.

I am puzzled by your reference to EGR valve. This item has nothing to do with the catalytic converter. If it is fitted to your car there will be a stainless steel pipe fitted to the exhaust manifold which ends in a stainless steel valve unit at the inlet manifold. This is required on California cars. If the EGR system gives trouble (as it will) your emissions can fail.

Get the catalytic converter yourself making sure that it is the right one for your car and either fit it yourself or take it to your tyre, exhaust and battery man who will be pleased to fit it for you at less cost than a dealer.

W.C. Fields (in a movie) sees a man working on a car at the side of a rodway. He leans over, knowingly looks into the engine compartment and says, "Must be the wheelbase."

In looking for an OEM catalytic converter for my car, there seemed to be two versions: one with an EGR valve and one without. I wasn't sure which one I should purchase. I guess I need to check under my car to find out for sure.

At any rate, it seems the general consensus of the group is that OEM parts are every bit as good as genuine Volvo parts. Even though they cost 80% less.

Thanks!

Cars without the egr valve were 49 state cars, those with were California cars. The cheap converters will not pass California emissions specs. Since you're in MD there's no problem.

BTW, I can get you a Bosal unit for $150.00. My shop is in Sterling, VA. Email off group for particulars if you're interested.

Try changing the oil and filter. On high milage cars the gas fumes go past the piston rings into the crankcase. It contaminates the oil causing higher emmisions. Give it a try and retest it.

That worked for me a few years ago on an old 240.

AFAIK Catalytic Converters do not have EGR valves. Unless the mechanic is using the term Catalytic Converter to indicate the model car you have. If you don't reside in California you don't need EGR (Exhaust Gas Recirculation) anyway.

I have used a gasoline additive called RXP and have had wonderful results. This stuff cleans the bejeezers out of the valves and fuel system.It has made me a believer three times!Bob

OEM parts are just fine, Volvo (and any other premium marque) puts a tremendous markup on parts.
