3s-gte rebuild - 6G Celicas Forums

Topic #81130 55 posts Started by Gt4Driver
Hello!
I got 1994 st205 celica. now it's time to rebuild the engine. it started knock very bad. i think it's camshaft bearings.
The knock started when i was driving, i stop and the oil was wery low.

I need advice where to buy new parts. i'm from Finland.

I got the engine out and now i have a problem. i can't get the trans off the engine.
i think every bolt is off.

help please!

here is some pictures

intake side

exhaust side
Problem #1

Your starter is still attached to the transmission. Those 2 bolts that hold the starter in also hold the transmission onto the engine.

Problem #2

The engine knock is likely not associated with your camshaft bearings, but likely something in the short block.
www.ebay.co.uk should have sellers that sell to europe and have plenty of celica stuff on there

What I think when you think I care
Ok. thanks guys.
need to remove the starter. then i can open my motor and see what is the problem.

First thing what I would is register here http://www.gt4oc.net/ and look if there is any good part seller for you. there ate a lot of traders and ST205 enthusiasts.

No more replicas... This is evolution... This isSS-four:)________[Featured Celica of 6gc.net @ 2010]_________
i use to get my parts in malaysia. Always the best parts 4 the best price.
looks like a clutch kit could do good for you...they arent that expensive...flywheel included its like 300$

What I think when you think I care
Yes it looks like it's time to chance it smile.gif is there any difference between 205 and 185 clutch?
they are the same I believe

What I think when you think I care

KEEP COOL UNDER PRESSURE
well. i think the bearings are bad, cause i was low oil and motor started to knock.
if i get parts from toyota Finland it's expensive.
Hi,

do not try to safe money, this can couse the next problem or a damaged engine again

i would prove to buy a used good working engine, possible the cheapest way

the knock is defiantly from the crank bearings. there are no cam bearings. keep posting pics of your rebuild. i wrote a good thread on rebuilding the 7A-FE you can use it for refrence

2001 Celica GT-S Turbo1997 Supra TT 6speed1997 Celica 3MZ/1MZ swap1990 Celica All-Trac
hello. it seems to be my 3 cylinder rod bearing is bad.
do i need to chance all four bearings? or is it good to chance only that what is gone bad?
they sell all 4 together and its not that expensive around 100$ give or take, The biggie is that once you open that engine you are paying the mechanic to basically take everything apart and put it back together might as well have new bearings in there...ARP bolts etc .

Just For example when i opened my engine up for a dead piston ring causing too much blowby I swapped the pistons out for forgies, forged rods and did all the bearings both main and rod bearings with some nice ACL race bearings

What I think when you think I care
It would be crazy to not replace all bearings! You should likely take the crank, rods, and pistons to a machine shop to make sure that everything is ok to go back in. ARP hardware isnt a bad idea, but will require additional machininh for proper fitment under torque load. Never go cheap on this type of thing. You should do as much as possible while you have the opportunity.
ok. So im gonna replace all bearings.
In toyodiy main bearings there is like 10 different mark and no. like mark 1, no.3 toyodiy
and acl there is only std, .025, .25, .50 acl
So do i just order acl std
Sorry if i'm asking stupid. but i don't get it.. confused.gif
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?

What I think when you think I care
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 kindasad.gif





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.
