2jzge Rear Seal
|
Sat, 25 June 2005 04:33
|
 |
I just put the gearbox behind the engine and lifted them up for a trial fit and..............lots of oil starts pissing out between the bellhousing and the back of the block,
I removed the gearbox to find that my rear seal is stuffed, leaking oil,
Ive never done this before, how do i go about changing the rear seal on a 2jzge???

Easy peasy.
Extract the old main seal with a small screwdriver - tap lightly between the seal and the alloy seal holder. Go to a bearing shop with the (hopefully not too damaged) seal. Pay $10 for a new non genuine one. (Repco does have them too but they wanted something like $27.) Then using a hammer to lightly tap it in. Make sure you do it evenly so you don't damage the seal.

Thanks for the advice mate,
I got the old seal out, the rubber was really stuffed (little rubber lips around the seal),
Went down to Repco and managed to get a seal for $15, it was sunday and i didnt would to wait untill monday,
I installed the new one, but i just wanted to make sure i did it right,
When i was installing the new seal one side went down slighly further than the other side, so i lightly tapped around the whole seal and leveled it out,
I could remember how far the old seal sat inside its housing, but the new seal sits about 3-5mm below the lip,
Is this ok???
Dose it matter how far the seal is in? i kinda figured the further the better, the only problem is getting it back out again, but as far as not leaking in the first 200km's i should be alright???

Usual stuff.....front main seal, cambelt, spark plugs, new oil and oil filter. For no good reason at all, I replaced the oil and filter again after 100 km of driving.
If you were slack like me, you'll have left the motor outside. Water collects in the spark plug valley. Leaving this water in situ will cause the motor to have a "mysterious" miss. Dry out the water. 
Can I ask what it is going in?

Of course you can mate, Its going into a 260z - hence my name 
Ive got a really nice red 260z thats my daily driver and ive got another 260z that needs a complete restoration,
Im thinking at the moment,
The Resto zed i would like to build as a dedicated race car
But will probably not use the 2jzge because im a tad concerned about how much HP i can get it of out, as in how much money it will cost to UP the HP of the 2jzge in comparison to just going out and buying a 2jzget,
So ill probably just put the 2jzge into the red 260z and it will be my daily driver,
and do something like a 1uzfe or 350chebby into the Resto Zed,
Ive got a garage, so i can keep my engine out of the rain
So i gots to take of the timing cover and do the front seal like i did the rear one, same goes for the cam seals???
Should i change the welsh plugs?
I want to avoid this - when i pulled down a 318 V8 i managed to lose a few welsch plugs in the block when removing them, didnt quite get the technique down pat ie.....tap the side and it spins around in its hole, then you pluck it out, a few of them just got pushed in,
The folk who i bought the engine off said the timming belt was changed at 73000km's and the engine is now at 101,000kms - should i still change the belt?
& should i should just the belt or should i do the ring gear aswell???

Remember how you said the rubber was stuffed on the rear main seal, the front main seal will be the same age and likely to be as stuffed.  So yes, I would change it. 
Wouldn't touch the cam seals (unless there is an obvious leak - you shouldn't need to disturb them anyway) or the welch plugs.
If the cambelt is only 40K old, maybe just check to see that there aren't any obvious cracks or abnormal wear.
Should be a nice conversion - bit more oomph than the L26. Tweaking the 2JZGE for more won't be cheap. That said, there is a nice set of extractors on supraforums.com.au for $600 ono. Absolutely no idea how these will fit in a 260Z.

mmmmmmmmmm..........dont know, worthwhile having a look at the extractors though,
Yeah i was thinking that even getting 20-35kws out of the 2jzge would be pricey,
Like bigger cams, slight head job and aftermarket ECU with good free flowing exhaust, and larger throttle body and injectors (but could probably avoid the larger throttle body and injectors for the first 20-35kws maybe.........)

I did ITBs, extractors and aftermarket ECU and made 148rwkW. I never ran it in standard guise but they generally seem to make about 115 - 125 rwkW.
I am aware of one in a Commodore ute with headwork and cams that makes 160ish rwkW.
Search for some of my old posts - I have a ported head, big cams and some hi comp pistons for one. When I get off my slack behind, I might even build the motor!

Thats pretty decent power, but ITB's would not be cheap,
Hi Comp pistons! isnt the 2jzge in stock form like 10.5:1 - wouldnt going much higher compression than that make it hate even 98octane fuel???
Do you know if the Commodore did the ITB's or just used the stock TB and injectors - and just did the cams and porting of the head?

Stock throttle body, cams and head (and I think a Microtech). This is third/fourth hand information so take the information with a grain of salt.
Stock non VVTi 2JZGE is 10:1, VVTi is 10.5:1. I'll be running 11.7:1 (when I eventually put it all together). Should be OK on 98 RON with adequate tuning. Plenty of people out there running high 11:1 on 98 RON. TODA make 11.2:1 pistons for the 2JZGE - they claim they're OK for 98 RON.
Link for extractors here.

Just curious, but how do you manage to up the power to 160rwkw with stock head, cam and throttle body???
Do you have the VVTI 2jz?
Just curious, but why did you go the 2jzge mate???

That was stock throttle body, with cams and headwork.
Not stock cams and stock head

Okay, I've got a similar problem. The rear gearbox seal of my autobox is leaking, to change it (I want to try it my self), only I'm not entirely sure how to do it.
Can it be done with the box still in the car?

If you can move the box 3" backwards then yes, it can stay on.
But you have to get the flexplate off, and to get that off you have to get a socket/breaker bar on the flexplate bolts.
Chances are box = out.

Not 100% sure, but i think if you go to tech (on the left hand side of the page, down the bottom on the blue menu) it has a whole heap of 2jz stuff, im pretty sure when i was looking through those Zip manuals there was instructions on how to change the rear & front gearbox seals on the 6-speed manual and the Autobox

$4 a stubbie....maybe a 4 pack. Oh, and if you have gout, load up with anti-inflammatories beforehand.
Pretty whacky stuff - Belgian white beer, fermented with orange peel and coriander seeds. Pours light and cloudy.
Thinks of Homer's Skittlebrau.

Hmmm, 4pack sounds like a goer for a trial run me thinks.
I bought a carton of Beez Neez about 2 months ago.
Still got 3 or 4 left...

Beez Neez??
Not too bad, you just cant drink too much of it.
Its made with honey (derr) so it leaves a thick sweet aftertaste for a minute.
Good to have a couple of, but I wouldn't use it to get smashed.
I leave that to my RedBacks.

Sorry to get of topic here fellas
But i have another question,
I have been thinking up a way to make my gearbox crossmember and i was thinking of retaining the stock W58 JZA80 gearbox rubber mount - its got 4 bolts that come down at the bottom of it, as i dont have the gearbox crossmember i would assume this is the only point (or points as there is 4 bolts) that connect the gearbox crossmember to the rubber boot and therefore the gearbox???
And, my rubber boot bolts have broken, anyone know how long they are supposed to be???

If you mean the bolts that bolt the mount to the gearbox, then the thread is about 20mm long from memory.
If you mean the bolts that bolt the crossmember to the mount, then the thread is about 12mm long.
