3s-gte rebuild Options

the std, .025 etc are in case you have spun a bearing and damaged it and you have to have your engine machined for example .025 of an inch there are larger ACL bearings by those sizes...does that add up?

Take caution. You need to have your crank journals inspected and sized before selecting bearings. Bearings are very important to your motors vitals

you may be looking at a new crank sir...if i'm seeing what i'm seeing in this image. looks like the journal is torn up pretty bad...Some closer pictures would be advantageous.

www.lithiatoyotaparts.com should have everything for the rebuild. I'd go for some forged pistons at this stage.

what do you think about this? Do i need a new crank? i think it's not that bad

[enderswift]

that doesn't look bad. You're really only concerned about discoloration, or scratches that you can feel with your fingernail. Those directional marks look like they are mostly from the few moments the crank runs dry when starting the car. You should still spec out all of the journals anyway though, and if everything is within tolerance then you should consider getting the crank polished.

The close up picture looks a lot better than the other that I commented on. I'd still take that down to a machine shop and see if a simple micropolishing would be enough to clean up those journals. If not, you may consider having them machine the journals down (which would yeild the need for thicker bearings). 3rd option is to replace the crank.

Side Note: From what I can tell from the bottom it would appear that your piston side-walls are in good shape, which is a relief! Only downside to re-installing the stock pistons with NEW rings is possibly a little oil consumption.

Looks like your number 1 and 4 rods have seen some heat, and may need a little honing to make their mating surface a little cleaner (not 100% necessary, but you're already in there so you might as well).

Recommendation:

If you have the resources...86.5mm forged pistons (you would also need a bore and hone for this), ARP hardware, Rod's resized and checked, Crank micropolished, and ACL Race bearings.

Ok. the car was running great before the bearing go bad and it's almost stock and will keep it that way.
So this is what i'm gonna do:

Put the old pistons in,
get the crank to the machineshop,
acl bearings,
,,,

You need to have the crank machined first and ask the machine shop what size bearings you need. It will likely be std ACL bearings if you have your crank journals slightly polished.

Hello!
Got the crank back from machineshop, std ACL bearings are in and today i go buy some gasgets from toyota dealer..

[bsamps4]

Sounds great! Did you put new rings on the pistons, or did you leave them inside of the block?

[Gt4Driver]

Old rings and pistons.

[bsamps4]

If you're running the old rings make sure to check your oil level periodically just to ensure that you're not experiencing any oil consumption.

put the engine in today

Few pics

[bsamps4]

Great pics man! Hope it runs as good as it looks!

Little progress

Ok. one question. My timing belt side driveshaft wont go enough in. Or is this okay?
