Help Bent Lifter?

[99Dodge1500]

I just bought my 96 Eagle Talon TSI AWD and knocked when I bought it from the guy, what could cause that, me and my dad think it is a bent lifter, or a bad crank barring, can any one help me?

Usually there is no mistaking a rod knock for any other noise coming from the engine, but it is possible that you could just be hearing valve train noise if your not sure what either sounds like. Try and get a video clip posted up if you can.

These engines do have noisy lifters so it is possible that could be your noise.

Thanks for the info I just noticed that I put this in the wrong place, thanks for responding though.

No worries.

Does it knock really loud when started cold and then get better as the car warms up? How many miles are on the car?

 

[99Dodge1500]

No it does not stop when warm, around 160,000

Piston slap, bearings, crank pulley rubber is worn, not a bent lifter though. Lifters are tough and wouldn't get bent. They are not push rod engines. Does it get louder with the rpm's? Only way to find out for sure is pull the motor.

I really don't want to start it because I am afraid to make it worse, I am going to start to pull it apart this weekend.

Probably a bad rod bearing, possibly a bad rear balance shaft center bearing.

Would I hurt the motor if I started it? I am new to turbo cars is there anything I should look at on the turbo, not for the knock because I am assuming that won't cause a knock?

 

[Defiant]

It's already hurt. Running it more will hurt it more, just like any other motor.

Ok, before anyone jumps to conclusions...drain the oil. Usually, rod knock bad enough to be so pronounced that it would raise a red flag, would not go away when its warmed up. It SOUNDS like a bad lifter since it goes away when its warmed up. Drain the oil and look for any metal shavings. If it is a rod bearing, the oil will look like metallic paint... Do that, if you see no debris and the oil is free of any metal, then its just your typical bad lifter.



CORRECTION: now that dyslexia isnt getting the best of me, i saw that what was really said is that it doesnt stop when warm..sorry. . either way, drain the oil anyway to look for metal shavings just to seal the deal that its a bearing.

Thanks I am going to my dads shop this weekend to take it apart, the only problem we will have is the oil pan because he doesn't have a lift, so it looks like we have to go Old School with some jackstands.

Interex, don't tell him to run the engine anymore. Think about it, if its a spun bearing in the crank, the spun bearing will sit and spin up and slowly shave the metal off of his crankshaft! So if he keeps running it he will not only have to buy a rod bearing kit, but also a new crankshaft. I just say don't take a chance because a spun bearing can do all sorts of different things when blown. It can shred to pieces, or shave off your crank seat.

But to the car owner, it could be a bent rod too , you never know, and if you run it, it'll keep knocking on the cylinder wall like my old Honda b16 until the cylinder wall is as jagged as a tin can.

Lastly, im not sure about dsm's, because i have just bought a 95 eclipse and slapped every thing i could on it, but did the owner run it through any water by any chance? It could have hydro locked since water cant be compressed and the bottom end would have blown out.

Just tear it down, those motors aren't bad to take down. Also, dont be cheap either!! When you tear it down, do a ring job on it too, it has the miles for it!!

Hey thanks for the info, I believe it is a collapsed lifter, I still have to change the oil, so when I do that I will be checking for metal shavings.

If you think it's that, while draining the oil just pull the valve cover and take a look at them.
