You still might have to replace the O2 sensors, they get overheated from the rstricted exhaust (bad cat). You probably will get a bit better milage when new ones are installed.

Yea, I hope to get a few dollars out of it. I think you have to write the vin on it and take a reciept showing you bought a new 1 to sell them I think.
Helps prevent theft.

You still may want to replace the O2 sensors. they overheat and give false readings if the converter is plugged and gets hot.

Ok, so far 1000 miles and doing great. Towing and all.
He is happy and no check engine lights.
His oil leak has slowed down to near nothing to.
But I will let him know that we should change them.
thanks for all you all's help.
Still aint had a full load to go to the scrap yard but will friday so I will see what this convertor brings.

I did want to say the 1 I bought from ebay had a small area around the threaded fitting that the welder missed. I had it welded by a certified welder and let the folks I got it from know they need to keep a check on these things. I didnt have time once i got the truck apart to wrestle with returns and such.
They refunded some money to make up for the problems. So that ebay vendor will make good on their items.

Just thought I would follow up.

I took the old convertor to the scrap man.It had come apart inside as I could see when I cut the pipes off it.
It brought 35 bucks. The man did say had it not been burned out, he woulda gone 70.
But that is better than nothing.

Well to quote the lawman on the Blues Brothers movie, "It's that Sh-t box Dodge again". In my shop.
I just would like some input.
Here is the low down. 318 engine,automatic transmission
Oil was synthetic in the truck first 100,000 miles. Dad bought it and went to Havoline 10-30. Oil has been changed every 3000 miles since my dad has owned it. Little cards in the glove box with dates and such.
Mileage is up now to about 280,000. Truck was running fine until a couple months ago.The transmission slipped and then something really jurked hard in the transmission and my dad was barely able to limp the truck home. Once this major jerk happened the check gauges light came on and the oil pressure dropped to 0. It was only a couple miles home but when he parked the valves were rattling a bit. A breif wait and restart,the pressure is normal.


We had the transmission fixed last month and figured the oil filter might be stopped up or something as it was a Fram. But changing the filter didn't help. There was a large shaft in the transmission had froze up in the bearings and there was all kinds of stuff bad in it.
What is happening now is the truck starts,runs fine for a while down the road, and if you make gentle turns and stops, no problems. But it seems if you make a hard turn or stop, the check gauges light comes on and pressure goes to 0. If you drive it any like this,valves will start to rattle. So of course I cut the engine off, wait a minute, crank back up and go.

If the pressure was going to 0 and no rattling, I would change the sensor. But the rattle gives me the impression there is less pressure than desired.
The truck in the shop now. I am looking to pull the oil pan and see if I can find a issue with clogged pickup screen or tube or something of that sort. Will probably put a new oil pump in just for good measure being it aint a cake walk to get to it.

Would it be possiable to get 1 of those cameras and shine it up in thru the oil drain hole and see if there is something obvious to save some work? I don't know how they work or how small the camera thing is. I think the hold is like 1/2 inch.

so there is the story, any ideas or hints?
I know, trade the pos, but try explaining that to a 82 year old man that loves his truck and does not like the high prices or taxes on a new 1.

Pull the pan, probably has sludge in it plugging the pickup screen. Park it and it settles, drive it and it picks it up again. Best to replace the pickup screen, the mesh collapses against the housing leaving only a small area for the oil to get through, it will plug much quicker than a new one.

I have a friend who had a van with, I think, a 318 in it.

On a trip, the oil light came on and, foolishly, he drove it to the next town. THAT cost him a new engine!

As he described it, there is a plastic(?) piece on the oil pickup that broke, causing the pickup to fall off resulting in loss of oil pressure.

In your case, I don't think the pickup has fallen off because oil pressure returns. It may be an air leak or something that gets worse when the oil is hot and thin.
