1JZGTE Problems

Damn, i thought these motors were trouble free etc!!! I have the problem with white/blue smoke when stopped, and now, everytime I give it some stick, there is a miss, sometimes, sometimes not, like high in the rev range, its like the same sound, auto soarers do, when changing gears. It gets tuned again tommorow, with more boost, but Im worried about the oil smoke, I dont seem to be lossing much oil though, kind of strange. Im thinking its the valve stem seals. Geez, this is the only toyota, I have problems with! Turbos went etc.

you sure it's oil smoke and not petrol?
if you've got a miss high up, I'd be checking your plugs - double check the gap (0. and make sure they're nice and sparkly clean

Get a compression test done on it as well.

The valve stem seals in my 1JZ are completely shagged. Most times when I brake I get a puff of white smoke out the exhaust, but it still doesnt use any oil. I dont think it takes much to create lots of smoke. I hadnt driven the car for a few weeks, that much oil had made its way past the seals and settled in the cylinders that when i started it it had a miss at idle casue the sparks might have been a bit fouled by the oil.
So I took the old girl out and beat up on her, floored it in second till redline and away went my missing problems in a big cloud of white smoke 
If the head gasket is the curse of the 7M, the valve stem seals are the curse of the 1J!

The compression test is easy all you need is a compression tester and an assistant.
Pull out all the spark plugs
pull out the EFI fuse so it's not pumping fuel
get the assistant to hold their foot flat on the throttle
put the compression tester on the spark plug hole for the first cylinder
get the assistant to crank the engine for 5 or 6 revolutions then look at the pressure
repeat for the rest of the cylinders.
Or of course you could get a worshop to do it. I suspect this would most likely add more than the cost of a timing light, that you could use whenever you want, to the bill.

Yeah take that bitch out and go nuts!
I use my white smoke cloud to help get away from evil villans like 007 and bitman do, so it's not all bad.
But if you dont have any enemies id just replace the valve stem seals

IS that a big job? I dont have the tools, or resources to take the head etc off, so Im thinking, its an expensive option.

Buy the seals yourself then ring around some workshops to do the job.
I seem to remember a thread with someone mentioning a $400 drive in drive out price including seals. But I also may have just dreamt that, I do alot of dreaming 
BTW the head does not need to be taken off, they can be replaced while all still in car, compressed air is a must!

who the hell is bit man and yes smoke is great especially for tailgaters muhuhahahahaha, that'll teach em for sitting on my ares, drop back to second accelerate hard watch revs climb over 3krpm and watch their face in the rearview mirror, classic. Was also good at school when this bitch would repeatedly park right up your arse and make it impossible to get out, so neutral couple of quick blips of the throttle and revenge was sweet.

Hey guys,
Just got the car tuned, turned 210rwkw @ 13psi, but cylinder number 5 is low on compression.
Went like this:
Cyl 1: 180psi
2: 180psi
3: 180psi
4: 180psi
5: 120psi
6: 170psi
Could be anything huh?

that is what i did
It is a gamble though. I have low oil pressure but I have been told it is just the oring needs replacing. Then you will have a spare also.
I am going to get around to fixing my spare and then have 2 working engines

I also did this and have parted out my original engine. You should get your money back. A good second hand engine minus turbos and alternator, starter, ps pump and aircon will only set you back about $800.
The gamble didnt pay off with me on my second engine too, once again the valve stem seals are screwed. Id definitely get them replaced first.

Yeah, ok, So I plan to buy the motor, take the head off? and replace the valve stem seals?? I wouldnt know how to do this, but I can get the motor in and out of the car. What do motors usually go for? Any contacts??

No you dont need to take the head off. When you pump compressed air into the cylinder (with springs removed), the valve stem seal will become exposed, just slid the old one off and slide a new one on. Ive never had a 1J top end apart so im not sure about taking the springs off but at a minimum you will need a valve spring compression tool. Maybe someone with more knowledge can advise here?
For motors get a copy of zoom and start ringing around. Make sure you call the interstate companies too cause it might be cheaper to ship it into your state compared to what the local traders might be offering.

There are some funky valve spring compressor tools around, they clamp on to the spring from above and you use a socket to compress it... most auto places ahve them and they are for the situation like this where you want to keep the head on while replacing the seals.
They aren't gonna be cheap I dont think but they are worth the money.

You definitely need valve spring compression tool. Engine valve springs can be quite dangerous!

Hey guys,
I got the engine cheked again, Compression was like:
1: 175
2: 175
3: 175
4: 175
5: 145
6: 165
Any idea what it can be? Also, would faulty valve stem seals, make compression read low? If I have to change the seals, do i need to take the head off, Or can I use that "special" tool?

Compression is measured when your valves are closed, so if there is a dodgy one no it wont effect your compression.
Id say compression ring in cylinder 5 is a bit worn.
And no as above you don't have to remove the head to change the springs. Normal valve stem compression tools work by grasping the head which means you can only replace/remove with the head loose, but you can buy a special valve compression tool to do it with the head still on.

Thanks Skip, sorry for asking the same question twice, what a dickehead haha. Ok, Ive decided (sort of) In building the engine. What can you guys recoomend, if I have a budget of 4k? While its open, i might aswell go aftermarket right? Sorry guys, im new to all this, well, im not really technical minded lol.

For 4k you could upgrade to a 2JZ block under the old 1JZ head. You could be the first 1.5JZ in a Lexus.
See what a low km 2JZ is worth. There are a few in the club here who have done this I believe so they will know what mods are required. I think they have to change the oil pump and possibly the pistons.
Worth checking that out anyway as an option.

I don't think for a rebuild 4k is gonna get you a whole lot more than a set of aftermarket pistons and maybe cams??
You could buy another 4 used 1J's for that amount of money.
If a had and wanted to pump another 4k into my car id lean towards a 2J swap.

I dont think 4k, would cover a 2J alone, arnt they worth more than that? Id love too, but the tourque of the 2J, will rip the W58, and my diff. haha. I just want to freshen the motor up, so, when i go out to a track day or drags, I feel a bit more at ease.

squirt some engine oil into cyl5 and do test again.. if it recovers it's compression, then it is rings (as the oil helps fill the gaps) if it doesn't then it's valve/piston probs..
