Anyone ever heard a motor make a noise like this? I took all the belts off and it still makes the same noise.

This started why my Fiance was driving it home from the track. It was running constant 14.1's on all three passes that night but it seems down on power a bit since the car has run 13.5's and 13.6's before in only slight cooler weather.

Sounds like my MTD lawn mower right before the engine seized up. I guess you could start by removing all the belts and starting it. Could be the blower..or worse.. a crank bearing, broken piston or connecting rod.

Thanks for the replys but I already removed all the belts. One person suggested a bent rod. I wonder if it might have spun a lifter? It does have a reground cam in it.

Yep, rod bearing spun and crank is now junk. Coincides with the lower performance at the track. No oil pressure gauge huh?

What was the root cause? Rod bearing?

In my case it was a crank bearing.

My 72 Mustang made that same noise but not as loud when it spun a rod bearing.

Guess there is not much of a point of pulling the top of the motor apart then. I'll just have to pull it out and see what I can find in the bottom end.

Thanks for all the good info guys. Any suggestions on what to do to the short block besides a rebuild? This is my girls daily driver so I was thinking nothing fancy. Just mabye do the block .020 over or something.

By the sound of it, I'm wondering if the shortblock is salvageable at all. How long was it driven like that? Minimum: crank, rods, pistons and a lot of machining.

It started making the noise like that about a mile after we left the gas station. She pulled right over within 10 seconds and shut it off. I started it again on the side of the road for about 5 seconds after I pulled all the belts off. We then called for a tow truck. It was then started and pulled into the driveway.

So the total run time while it's been making that noise is probaly less than 30 seconds.

I know when I spun a rod bearing in my car it only had a few seconds of run time on it and the crank was fine.

My 90 sounded like that one day after the head gasket blew going down the highway.. Next day I sold it for $850.00

Jason,

Look for a good shortblock from a donor car. Their are plenty from wrecked cars. I have seen a few engines on Ebay cheap.

You'll know when you get it apart.

Only donor I saw:

Yeah Chris has a few of my old motors I beleive all need machine work...I'll take what every fair value is...and well you can catch up with me when ever on that.

Just get the car back on the road. Also...isn't Luis selling the motor from his now totalled 89?...also Mike (Joker) is parting out an SC if I recall...all good options for the time being.

She made 3 passes in it at the track. It only seemed off a little running an adverage of 14.1 at about 97-98 mph. The best pass it ever did was last November in the 32 degree air and that was 13.5x

The motor let go about 5 miles after we left the track. I'm just glad mine stayed together so we had a car to ride home in. I was gunning for 11's but when I fogot to turn the IC fan on and only ran a 12.48 the heat was too much and burned up a couple plugs so I called it a night.

You race your girl/fiance's daily driver?
You should probably let her drive your civic so she can get to work while you play racer.

I don't race her car. I race mine. She's the one racing her car. :D

She works from home so she dosen't have to drive far. No civics at this house. Her youngest son has a 95 bird. Her oldest son a 2000 Mustang GT convertable and we have our 2 94 SCs. The only odd ball is the Chevy Z24 that I drive to work.

Got the oil pan off the car. Spun a rod bearing on #6. Anyone got any tips on what replacement parts to use as far as new rods and pistons.
