    Recently Purchased '89, Motor Needs Rebuilt?

    Hi! 3 days ago I purchased my second Thunderbird, a 1989 Super Coupe. It appeared to have a vacuum leak. As it would heat up, it would begin to stall when I let in the clutch. Last night, I was driving and it began to make an awful noise, I will post a video of the noise, and on my way home, it began overheating. The coolant overflow tank was boiling. I let it sit over night. It is now back in my driveway and I have no clue what to do. I think that the noise is a rod bearing but am not exactly sure. Will it need rebuilt? Any input is greatly appreciated!

    Mike

    Yeah, that sounds like a rod bearing, and yes it means the motor will have to be rebuilt, or replaced. Replacing it with a good used one is likely your cheapest way out, but if you want to have it rebuilt, contact XR7Dave, as he is the go-to guy for engine work on these cars, and he is also in Ohio.

    Add cracked pistons/rings. Note at the 00.10 seconds the jet of smoke coming out of the oil service cap. Engine rebuild/replacement required.

    If you pull the dipstick, does it look like a milkshake? Same stuff in the overflow tank or radiator if you let it cool down and look inside?

    Damage is done, in any case - headgasket fail, most likely. Try not to fire it up again and open discussions with a reliable source for an overhaul or another engine.

    Good evening


    You could also drain a little oil in a small container and stir with a screwdriver. If the oil has silver "metal flakes/sparkles" while stirring this would be a strong indication the bearing(s) are shot.
