On my b16 i have a spun bearing on rod number 1 and i need to know if i am going to have to have the crank cut or replaced. You can barely barely feel the scratches on the journal and i have pictures. any advice is appreciated but i am strapped for cash as it is right now and i really need this thing working again. Thanks in advance.

 

Bump! This guy needs help! Would he just be able to replace the bearings and hope it works?

 

Bump, any help is appreciated. I need to be able to know this is going to work so i can sleep at night.

 

nah its done. look at the color of that journal compared to the others. it got way too hot for way too long. if you mic the crank you'll get to correct measrement. it'll never get the right bearing clearence and will knock. sorry

 

yeah that thing is done! you could try to find a new crank or maybe a gsr short block. my ls spun a bearing about 6 months ago andi was able to save it. there was NO discoloration on my crank and no gouges either. i could barely hear it. sorry for your luck man.HAPPY THANKSGIVING though.

 

ya when it's that black..

if you are that poor at the moment you can grab some bearings and plastiguage them. if the clearances are right run it if you have to, but start saving...

 

you might be able to find a complete shortblock for cheap, ive seen them for sale for around a $100.

 

The thing is i just bought this shortblock and i need this thing running. I thought the rule of thumb was if your fingernail goes inside the gouge it is done.. i can barely feel the scratch.. it is more of a vibration on my finger.

How long could it last if i just got a new bearing and used plastigauge to measure the clearance?

 

if you want it to last, I would sugest taking the crank to a machine shop and see if they can clean it up.

or find a new crank and replace the bearings.

If you are really poor and can't do either of those, get some emery cloth (really fine one) and clean up that rod journal yourself. Then you can plasty gauge it and see what bearing you need.

Thanks for the advice i really appreciate it.

 

That crank and rod are done, probably the oil pump also. All the stuff you did not find in the oil is in the block, therefore it all has to be cleaned.

Yea i already have a new pump but i would really like to try not to buy a rod and crank.

 

How "done" is it? The motor was running when it was pulled out so it should be ok to run untill i can replace it later right?

 

What ever you think. That is what you want to hear , right?

 

randomae,

That crank is done.

Here's a saying, I like to live by, " A smart man learns from his mistakes. A wise man learns from the mistakes of others."

 

Well, i will think about it thanks for the advice. One more question for you don, do you guys sleeve blocks or just p&p?

Thanks for being straight forward.

 

you need a crank.
you could also stroke it with a ls crank and rods

Stroke it? Why? Couldn't i just replace the oem stuff?

yea, you could, but its the “while im at it...” syndrome...

 

if thats a b16 i would sell it for like 50 bucks and buy a used shortblock for between 100-250 and be done with it

 

This is my second b16 block both had bearing/rod/crank problems.. i think i am sticking with the b16 internals because i don't have much money.

 

over-rev? oil starvation? or did it just give up on you? curious to know.

 

even if a machine shop can cut the crank it'll cost over a hundred.

ls rods and crank are still oem "stuff"
you'll just need some pistons
