    L05 350tbi knock

    I’ll pull the accessory belt off when it’s still cold, and take it for a short drive and listen.

    L05 350tbi knock

    Makes sense. I forgot to update saying that I had put changed oil twice since I originally posted this and used a/c delco filter both times

    L05 350tbi knock

    Alright. Forgot to update, it’s got 10w30 synthetic with a delco filter. I’ll give you time stamps of the sound. 7:45 you can hear the noise, and 12:05 ish you can see the car is warmed up snd the noise is gone

    L05 350tbi knock

    I have already made a post on this, but I now have lots of video Take a seat this is gonna be a long one. Back in June I bought a 1992 Buick roadmaster wagon that needed it’s 700r4 rebuilt. I was told it has 200,000km on it and the cluster which reads 300,000 was swapped out of a different...

    350TBI weird knock

    I know this a a double post, but I have more information to add as well as a video of the noise. Okay, to start I would like to say that this is not a truck, but infact a 92 Buick roadmaster wagon. This forum is my last resort as I’ve had no success anywhere else. Take a seat this is gonna be...

    I checked the bolts, they were tight enough that it was turning the engine over when I tried to tighten

    350TBI 1500RPM engine knock

    Jesus. I guess I got very lucky. I didn’t check this till right now. I turned it by the crank bolt. It didn’t snap off

    350TBI 1500RPM engine knock

    My current plan of attack is to first just do a visual inspection of the starter and flywheel while having the car up on a curb. Then take it to my school and put it on the lift there while someone holds it at 1500 rpm while I’m under it. Then unbolt the flywheel from torque converter, push it...

    350TBI 1500RPM engine knock

    Nope not at idle either. Only 1500rpm. I don’t think it’s a rod knock either

    350TBI 1500RPM engine knock

    Also, I can’t use a mechanics stethoscope just because it only makes the noise while driving the car

    350TBI 1500RPM engine knock

    350TBI 1500RPM engine knock

    Okay. I’m going to out the car on a lift and see if I can figure it out asap

    350TBI 1500RPM engine knock

    It would makes sense that it’s the flywheel, because I don’t remember hearing the noise until the shop had the car and rebuilt the transmission. Does it makes sense that it makes just at that rpm?

    350TBI 1500RPM engine knock

    Is there a way to check the flex plate without removing the transmission. Meaning is it possible to see through the inspection cover

    350TBI 1500RPM engine knock

    I know the timing is supposed to be 0, I was retarded it to see if there was lots of carbon build up or something. It’s currently set a 0 again. I will look into heat shield, u joints and flex plate

    350TBI 1500RPM engine knock

    Could be. I’m just so confused because this thing runs really good. I’ve floored it like once when I first got it and spun the tires all through first and chirp second. Haven’t even made it half throttle since becusee I’m concerned about the noise.

    350TBI 1500RPM engine knock

    It sounds like it’s the drivers side of the engine bay to me. My dad cant hear it outside of the car either. Could be u joints though.
