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.

Well, I can say this, I pulled the pan, and the pickup tube has a screen on it, the screen has a metal shield around it. There is only a 1/2 inch by 1 1/2 inch slot for it to pull oil. The area covered by the shield I was able to stick a small screw driver up in there and pull out all kinds of crud.There was even crud stuck in the parts you can see. There is loose crud in the bottom of the oil pan. there was a small amount of oil still in the pan when I drug it out from under the truck. The crud in the pan would slosh around with that oil So it makes sense it would slosh when driving.
I told my dad I can not promise this is THE problem. But I can say it is a real problem that would conceivably cause the oil pressure issue.
So I will begin the parts accumulation process Tuesday.

in the 70s ford had plastic timing chain gears. they would fall apart and the timing chain would need replacement. you had better pull the pan and remove all the little pieces or your gonna see this exact same issue.

I would pull the valve covers and see how badly the top of the motor is gunked up. May be worth it to pull as much gunk out as you can before putting the pan back on.

That's what I expected you'd find. If you look at the screen it is probably sucked up against the housing, the only place it can rally pull oil is where the 1/2" tube is. Clean the pan out and install a new screen, should hold you for a long time. To really clean the engine you would have to remove the valve covers and intake, the crud resembles coffee grounds. I would try just the pan first.

Well I went and got a Melling pump and they had to order the tube with screen but it will be here later today. 1 piece gasket so that won't be to much trouble to install. The screen on the new tube is a fully round and exposed screen without the "shield" that has allowed the old 1 to clog so much. Must be a improvement. I could have cleaned or replaced just the tube-screen and probably got by just fine but I fiqure this way I will eliminate several possible culprits.
105 bucks worth of parts but if it takes care of it, then it was a cheap fix as opposed to a new truck or engine.
Thanks for the help.

I must say, I was always under the impression that 3000 mile oil changes and good filters were supposed to help prevent this type thing.

Did you pull a few rods and mains to look at the bearings? I don't know if it's possible to roll some new ones in there while the pan is off.
I Agree with the 3000 mystery vs sludging up so bad. Is it time between changes that caused it? Crappy oil? Running too cold? Short trips whereas it never gets the oil heated up to drive out water?

This was a common problem on the Ford small blocks, lesser problem on the Dodges, hardly ever on Chevy's. The "sludge" is actually a hard carbon type material, resembles coffee grounds. I really don't know what the cause is, why one engine and not another. Best guess is hot spots in the head, exhaust crossover. Maybe the Chevys run cooler here, maybe more oil flow keeps it washed. Regular oil changes didn't prevent it, but lack of changes sure made it worse. We had a customer with a Town Car that was done 4 times while he owned it.

You know now that you mention Ford and this issue, I have a 87 town car that I was driving to work and that 2 dollar part failed that caused the transmission to tear up. Can't recall the name of the part.
Anyhow,I let it sit a while and it had a intake gasket leak. So I fixed it and was going to take it to the transmission shop. There was large "sheets" of this hard gritty stuff under the intake.
Once I got the engine cleaned up and reassembled it ran great and I was going to the shop after I got it inspected and insured,the engine started ticking. At that time I was not aware of this type thing and it has sat since.
If I ever get caught up, I might pull the pan on it and see if this is the same issue and try to get the car drive-able again.

My dad ask if he could help in some way this morning to get things done. I said, "yea, clean the oil pan and clean up the oil spill under the truck and that way I can get started soon as the tube comes in. He is down there now scraping and grumbling, "I need to sandblast this!" I said no,just scrape!.

I believe the oil has been overheated and cooked.
Engine flushes and most solvents do not seem to dissolve the gritty particles.
Crud has to be mechanically removed.

I believe most of the cause is cooling passages that have accumulated rust and scale, allowing localized overheating.

Cleaning the cooling system and using an oil with a higher temperature rating will help. Look at the motor oil test report published on this site, and change to one of the higher rated oils.

Well it was a successful repair. All went well except for that ##*# starter fell and hit me in the top of the forehead. Had I not been on a creeper and saw it coming it woulda got me right in the eye.

There had been a oil leak on this engine for years. I found it when I pulled the oil pan gasket off. It has been into before and the previous person did not get the gasket in it's slot on the block. It was squashed outside the pan.
Engine is quite and it has been drove about 25 miles without the red light and the dinging!
Thanks for the help.
We put havoline 10-30 it for this. After about 400 miles or so we are going to change it again.

Blue, at 280000 miles you are way overdue for a new timing chain if you haven't done so already. Replace the water pump while you're there. The slack in the old chain causes cam timing changes and a new chain will wake up that old 5.2
