Ok guys, tomorrow i will do that little test with the hose...

by breather hose you mean the one that goes from intake to the head ? and should i disconnect it before i start the engine or when its up to normal temp ?

 

The one from the side of the vlve cover to the intake piping - NOT the one at the pcv valve - which is the one that goes from the valve cover to the intake mani.

 

i disconnected a hose that goes from the turbo intake to the side where some ppl put filters, and yes i feel a little air .


i will do compression test tonight after i pick the gauge up at the auto store, can you guys explain to me how to use it and what else do i need ?

 

do you see smoke from that outlet when the engine is warm and running? Also pull the engine oil dipstick and check for smoke when the engine is running and at operating temp

 

Ok, i will check for smoke out of dipstick in the next 5-10 mins when car warms up .. and no smoke is coming out of the side outlet.

do you know how to use the compression gauge ?
i'm going to buy it now and will take my laptop with me so i can hopefully be directed.. i'm gonna look for DIY on that witch.

here you go my brethren, how to do a comprssion test on a scion tc.

 

cool thanks man..

ok, i just checked the outlet for smoke and no smoke is coming from it, and no smoke from dipstick.. and no smoke from tail pipe either...
maybe its a parania like crush said., but to be 100% sure i'm going to orileys now and going to buy the gauge and check compression, the cheapest they got is liek 22 bucks..

 

it never hurts to check mang...22 bux is a decent price imho

 

4-150
3-190
2-175
1-190

 

i'm sad now

 

Weird - 150 is awefully low to not see any other signs of blow-by - hmmm i dunno what to tell ya. id retest - make sure engine is at operating temp first and make sure to do the same crank time on each test.

 

2 is slightly low but not much from what iv heard, 4 looks like an issue but not a bad one really...if it was like 90-110 then oh yeah you got problems....like thendawg said just retest and see what you get then compare the two tests. you could have given #4 less of cranks than the others by just a little. so far anyone that iv heard have bad rings normally had lower compression than any of your readings thus far.

 

oki, also guys i filled up with what i think really bad 92 octane gas on my base here and the moisture from tail pipe is a rediculous amount !
I added some octane booster today and some other aoil additive.

also i took pics of my spark plugs and they were black , one messed one up and autozone only had 2 step colder , so i installed new spark plugs 2 step colder.

i also took a small video on sunday of how it looked as far as the smoke and also took a pic of the turbine wheel , i will upload them next.

 

i noticed that turbos tend to throw alot of moisture out the tailpipe exp when your not running a cat....i should have taken vids of the last time i dyno'd , you guys would trip at the amount of water that came out when it was warming up. id say about half a cup of water came out on one rev.

 

thats probably how much i get, lol.. i'm gonna put the cup next time maybe it will collect some.. i'm gonna upload that picture of spark plugs and turbo so you guys can see.
Maybe i need to inspect my charge pipes again...

maybe compression test again in few days. and i really wanna get rid of this gas i got in the car i have a feeling it sucks..

 

 

yeah you need new plugs doesnt look like you detonated though, i have 3 sets of those fouled plugs but that what you get for running too rich lol

 

i cant really tell but does any of the plugs have like a shiney black coating on em, or all they just a dull black....shiney=burnt oil=bad rings or bad valve seals dull=carbon build up=running rich

 

nope nothing shiney just dull black... Autozone didnt have any 1-step colder plugs, but they did have 2-step colder. So now i'm running 2 step colder, how can it affect me ?
also i did the video on sunday of how the car was smoking while pressing accelerator at idle... it was a little chilly outside due to wind, but not cold..

here check it out guys. I'm a little confused as to is there something wrong or not with a car....

how's your afrs man? cold weather and a really rich mixture can do that too especially if the car is not yet fully warmed up.. condensation inside the exhaust will cause a lot of smoke. and 2 step wont do anything IMO, but are you getting iridium plugs?
