i start UTI next year :excited
Hopefully i enjoy it, it seems like a good school
time to order some overnight parts from japan
Kenny Tremont FTW:number1
save your money ,school is a shitty one …go to wyotech way better
Wow u cant balance a crank with out rods and pistons. hmmm
I wonder y cranks come from the factory with bob weights installed and drilled out spots on them !!???:Idiots
:ohsnap :ahh
So after long conversations with my teacher he is going to allow me to change the crank and all the bearings and the oil pump.:number1
Here are some pics of what i got done today.
This is one of my ROD bearings. thats probably the best looking one.
Heres Another Some major chunks missing. lack of oil psi
Got most of the Coolant lines, throttle cable, connectors, and stuff like that off today
This came from my oil Pump Arm that goes to the bottom of the pan.
I think ill buy a new oil pump:clap
And i have a question for whoever has pulled a swapped motor, Does the tranny need to come out?or can i slide the clutch and flywheel by?
I dont kno if there is enough clearance or not.
Thanks
tranny has to come out with motor, you:RE right.
Dude my brother just had the same problem with his A4. The old dude that had it before him prolly didnt know enough to let the turbo cool down after driving it, and there was alot of sludge build up and it clogged the oil passages. Alst night oil light came on, and came to a nasty sounding hault. We have to pull the bottom end to see how bad it was.
2 toasted oil pumps in the same week for Shift… not good.
Glad to see the school is helping you… thats awesome!
Damn bro that sucks, yea this oil pump is putting me threw alotta stress, i have to tear down half the bottom end just to get to it…
Not to mention the crank and bearings.
Its gonna end up costing me like $500 for everything which isnt bad but idk
I just hope that this oil pump lasts a while, i know 9000RPM is alot but its so fun haha :yas!!
wow when im right im right i guess 4 years of auto tech school has paid off too bad for you i was right on the thats gonna cost alot
is ur buick white?
doesnt take a rocket scientist to figure that out :Idiots
There is a big difference between static and dynamic balancing of an engine rotating assembly, and drill holes in crank counterweights are only part of a total balance in reality but this is not a thread for engine balancing and first/second order vibration that occur in four cylinder motor(well mostly second order as first order is nearly canceled)
Wow, cracked outer pump gearotor. That usually happens from a suck OPRV but high rpm cavitation can cause it too.
Good luck on the rebuild 
Ok so i have a question…
If i put this new crank in, will it have to be balanced?
I thought they came balanced. soo idk im getting some different sides from everyone
and im guessing static and dynamic as in the same as a tire balance machine?
Same concept?
if ya do a diff crank ,yes the whole roating assembly will need to be balanced …its kinda like balicing a tire ,if ya balance only the rim without a tire and then install tire its still gonna shake ,but balance as a whole it wont
How would i go about to get my assembly balanced?
And if i didnt it would most likely be unstable and jumpy at high RPM’S
if ya dont balance the motor will shake itself to death at all rpm,s …take the crank rods, pistons to a machine shop and have them balanced no not the boces machine shop but a outside one lik hunts c/p engine builders of that nature
Ok whoa slow down here a bit…
IF the crank is statically balanced to factory standards and the rod/piston/ring assemblies then you can just drop the crank in with no ill effects for a OE-like assembly. There is enough deviance in the four cylinder motors design for such and most will tolerate gram differentiation quite a bit. Four cylinder motors with flat plane cranks have a design nature to cancel first order vibration. Second order vibration is a different beast due to different ramp up speeds of the piston assembly pair going up vs the pair going down. That’s why many four bangers have balance shafts, to counteract the 2nd order vibration that acts twice the speed of the crankshaft.
This is not the same application with cross-plane cranks such as in a V8. Four cylinders can get away with it(flat plane that is) and so can V12’s(but show me a v12 you wouldn’t balance!)
Now that doesn’t mean I don’t HIGHLY recommend that you have the motor dynamically balanced at a machine shop like us(Hunts) but if you’re just slapping together a quick motor to get a DD beater up and running well then the cost may not be worth it to you.
The pistons, rods,Rings are all stock…
my car has value to me, its not just a DD…
But if i drop the crank in with factory balance with factory components i thought it should be fine.
Im just wondering because im curious and if im gonna get a new crank i was just gonna rip the bottom end apart and not remove the head and shit…:ahh
