your valve stem seals are shot
not really a big job but around 150-250?
if it still goes hard and nothing else is wrong with it keep it.

That's a hasty diagnosis. It is hard to tell if it is just valve stem seals by the description, they tend to show after some idling or vacuum condition.

becuase your opening up the engine.. you might aswell get it right and do all of it for reliability
get a compression test done see how the results are they would help you decide on what todo.
otherwise if it all seems good then its probably just the seals.
are you burning alot of oil?

Im with yellowrolla, frankly i doubt it to be valve stem seals, its more likely youve blown the head gasket with white smoke indicating water is mixing in the combustion chamber somehow.
IME worn stem seals will blow a little bluish smoke after idling for a while then drive off or if you floor it after coasting or as YR puts it ....

yes i agree with yellowrolla and IRA11Y as well because when the valve steams seal are worn it will blow a bluish smoke like IRA11Y said especally when alowing the engine to idle for a few minutes and then opening the throttle if the seals are worn or damaged a disarge of bluish smoke can be seen from the exhaust but I have seen some cars under the hammer blow a blackish grey smoke whats that mean? followed this xd for a kilometer and evry time he gave it a bootful i notice this from his car and thought ok that can't be a good sign for that car

if its stem seals blowing blue smoke will only be when you first start the car. As when they are stuffed, oil builds up at the base of the valve,and stays there...when the car is fired up again, it blows the smoke to signal burnt oil. It will NOT happen when the enging has been running and there is oil up circulating in the head.

thekemist wrote on Sun, 09 May 2004 18:20 | well my 100kw motor blows a hell of a lot of smoke when i rev it. its white smoke so i know thats no good. What should i do. how much will it cost.. i want to keep my car for maybe another 2years so is it really worth rebuilding the whole engine.. how much will it cost roughluy.. or should i throw in a second hand motor (import) .. how much would that cost
opinions on what i could do?

How's the colour of your water, does it seem to use a bit of water. Put a sniffer on to it. Any compident mechanic or radiator shop will have one or something similar.

Rich = too much fuel in the air/ fuel mixture ratio. Unburnt fuel turns comes out as black smoke, not the most pleasant smelling. is your car carby or efi ?

its efi
as for the other question no it doesnt really use that much water. radiator is always at capacity.
i just want to work out whether its a big major problem or something smaller which means that i dont need to take my whole engine part etc etc ive seen cars click over way more kms than mine without blowing smoke apart from that ive never had a prob with it

just rebuild the whole engine.
gasket kit: $250 ish from memory
main bearings ~$30
big end bearings ~$30
piston rings ~ $60?
and your cheering.
you could get the block and head decked and chemical cleaned for like $250 ish or get it bored and honed slightly and get some new pistons.
all of this should cost less than another motor, this is assuming you assemble/disassemble yourself, not hard at all with a workshop manual. bang it all back together and it will last ages.
im guessing it will be a combination of both stem seals and rings, if its still running ok i doubt it is the head gasket.

bearings more like about $70 rod
$90 main
Thats if you buy ACL stuff, which i strongly reccomend.

well mine wern't
they were about $30
this is for a smallport 4ag
ACL as well
i didn't buy rings seperate coz they came with my pistons.
ACL, not forged or anything - $200
so $150 for rings is expensive in my book

OK well i think i wouldnt mind rebuilding the car if its not going to cost that much.. this is what i would like you guys to do if possible. i have a friend whos dad is a manager at repco and he can give me a pretty generous discount if i order thru him. so if possible could anyone list me the parts i would need to rebuild the engine with how many etc if possible the model numbers etc and i will try get a quote from my mates dad and then see how much it will cost me.
its for the 100kw 4age motor out of 89 corolla sx
cheers

if your not losing coolant, and the smoke is white, i'd quite bieng paranoid about it. It's most likely evaporating water in the tailpipe. Get them video's posted up somewhere and you will get a better opinion.
Does the car continue to smoke after a good drive?

wow! Does it use a shit load of oil, or water?
Looks like you'll have to pull the head off (minimum) and have a look around. Probably drop the sump also so you can undo and pop pistons out the top. Has this smoke just started or has it gradually got worse?

take it to a mech. it looks like either excessive oil smoke, ie. a popped piston or cracked head, or really excessive over fuelling. how does it run? have you driven it with this issue? how does it drive (power under load) has it lost power? does it make any noises? is it hard to start?

yeh ive driven it while it smokes kinda glad i havnt been stopped by any cops yet
i havnt driven it in two months cos i have a broken arm but when i was driving the engine didnt seem to be struggling when i do rev it it still feels smooth im sure it has lost power tho because it feels that for the amount of revs its doing it just doesnt have the pull that u think u would get(is that what u mean by power underload).... ill have to check it out once im able to start driving in a few weeks but im just trying to get a few ideas of what to do in the mean time

my SX is doing the same bloody thing, on start up its like yours in the videos, let it warm up for 5-10mins and its fine, then when ya give it a boot full it smokes more, but not as much as on start up.
mine doesnt use oil or water. Can ya do the valve stem seals with out removing the motor? and does anyone have a part number etc for them?

ACL seals:
PA 425 - 48 (I think the 48 may refer to quantity - so you only need 16)
Go to the ACl website and look for preferred stockists. Dont pay more than about 30 bucks for the seals.
Can do them with engine still in car. I'm even going to attempt it with the head still on someday . Guys on the forum have done it. If you take the head of it would be a piece of cake..but its the other stuff im worried about.
you would think it would be using oil though. Leaky or malfunctioning injector?

do you leave your car parked outside?
the grass seems icey..
cars with large tips usually do this at start up or when its cold
oh yeah get rid of the cannon man its soo ricey
get the traditional mufflers with the growls not the fart
