Spun a bearing

[Turbo Dog]

I had my timing chain replaced recently, and 200 easy miles later my motor is making a noise like the cooling fan is hitting something, only the sound is coming from inside the motor. I drove it slowly to the nearest mechanic, about 100 yards from my home, who told me I "spun a bearing". My question is, could the timing chain install have something to do with it? I have a date later in the week to have my motor rebuilt. What should the engine builder look for, as to the cause of my problem? The car has 155,000 miles on it. The timing chain had never been replaced before. Thanks guys!

I'd drain the oil and look for any tell tale signs first . then drop the pan if need be . see what going on inside before you part with any cash for a rebuild .

You took it to the muffler shop, didn't you? Dude, those are NOT mechanics. I've had nothing but very bad luck with those guys. They pissed me off so bad before, the owner had to come to my house on his own time to apologize and refund me. Stop driving the car, and drop the pan. You have just as much knowledge if not more than any local mechanic shop in this town. The pan comes out pretty easy, and then you will know. You can always come to this board for help, or call me or aaron. I know those guys at the muffler shop have done OK for you, but they are out of their league on this one, and you don't want to waste money. Do you have an oil pressure gauge by chance? Keep us posted.

I would follow advice already offered. This same thing happened to me after my timing chain was replaced. The culprit (in my opinion) was failure to properly prime the oiling system. I spun a bearing as a result. I heard the same sound you're describing after 100 miles. I'm glad I got my motor rebuilt, but is mucho dinero!

It usually has nothing to do with repriming the oiling system. When they remove the frontcover, antifreeze runs down the front of the block into the pan. Even if you drain the oil, it very hard to get all of it out. Antifreeze in the oiling system is a spun bearing waiting to happen. It's only a mater of time. It takes very little and it may be all evaporated when the bearing starts to really go.

The proper way to do a timing chain is to remove the pan and clean it out completely. This adds an hour or so to the job so a lot of people don't do it.

People that don't shut their car of right after blowing a head gasket (I't only a couple blocks to my house) suffer the same fate very often, too.

If I do need the motor rebuilt, what kind of warranty should I get?

Amen to this.I just replaced blown head gaskets acouple of months ago(after driving for a bout 75 miles before i realized what happened).As of last weekend, i have a spun bearing.
Maybe someone can give turbodog and i a little advice on what things you would do while fixing this problem,how much this is likely to cost.Thanks for any help(or any rec. on someone on the east coast to take it to once i get the motor out)

Well if you are a cheap bastard like myself, you can probably get away with just having the crank turned and replace the rod and main bearings. This all depends on the condition of the cylinders and rings though, but is a much cheaper route and can be done without removing the engine from the car.

You won't get a "warranty", no one does on race motors. I know you don't think its a race motor, but anyone who is decent with these motors is probably not going to say "1 yr. or 12,000 miles warranty", because we break stuff. It will be an agreement between you and the builder. They will know when you bring it back if its something you did or they did. Most builders will work with you if it happens to break. But if you blow a headgasket, its probably not the builders fault. See what I mean? Call ANS performance in Chicago, he's about the closest person and does good work. Get the steel main caps, turn the crank, new bearings, and some good pistons. Should run you around $3500 if you yank it yourself.

Anybody use the clevite nascar bearings? We just put some in my motor, the things look used when you take them out of the box. Supposed to be good, just look like they went around Daytona for 500 laps

Why are our cars so sensitive to a little antifreeze in the oil? I once had a Ford Taurus that had a blown head gasket. I probably drove it for a week with no heat until I brought it in to the dealer for repair. I'm sure when most people experience a blown head gasket, they don't rush to have it fixed, and when they do, they're not looking at an engine rebuild.

low oil pressure and tight clearances.

 

[blackbuick87]

That, and double the torque any Ford Taurus ever dreamed of making

If the original timing gear failed there may have been a LOT of the nylon gear in the oil pan and this could have plugged up the pickup screen causing low oil psi...

Kevins- I only had the timing chain replaced as a precaution. Nylon teeth weren't even broke. Maybe that indicates how well cared for the car is. Thanks for the help, though.

Dog just rebuilt a motor for a friend who had the same problem you are going threw. He put a new timing chain is and pulled the pan to check for any nylon gears. His pan was clean so i told him to re-prime the oil system. Did he NO heck two days later came to my work and he spun a bearing. Big mistake and big bucks for a screw up.
He got off with a turned crank and reused his stock pistons but still had to dish out some bucks for a rebuild. I charged him nothing just didn't for him nice guy. Take the motor to some one who knows what he is doing. If its a spun bearing get you wallet out and get ready to spend some dough.

Later Sean

Thanks Sean, but who is "Dog"? Should I call him for an estimate? Does he do good work?

 

[turbosam6]

I think he was calling you dog, since your handle is "turbodog".

D'oh! I had Jennie (daughter) yelling in my ear and didn't read the response too carefully. Kind of like Steve Wood. Thanks Sam.

Also cut the filter apart and inspect it..
