Heres a website with your symptoms. Try to use a strap wrench or channel locks with a rag so you don’t chew up the surface of the tubes.
The tubes have to be unscrewed and cleaned of the old sealant. Then resealed with pipe sealant.C8-)http://www.toyotanation.com/forum/103-3 … -5sfe.html

Another post full of WIN from College Man!
Personally I just use a pipe wrench, avoid the top of the tube as you don’t want to damage the surface. All I’ve done with those is remove them and clean the threads then when I reinstall the tubes I just put a light coating of RTV on the threads before I reinstall.

I’d say that’s how the guy in CollegeMans link did them too based on the marks on the tube.
I HAVE A BIG QUESTION… when I removed the spark plug#1, I saw oil on thread of the spark plug, but not on top surface of spark plug.
Does this a sign of SPARK PLUG TUBE seal bad cause oil leak around the thread of the spark plug? or have a valve seal bad?
please share your thoughts on this because I don’t want to remove when it’s unnecessary for extra work not solve the problem.
ERIC or someone can comments on this…
If your seeing oil on the combustion side of the plug that to me is valve guide seals or rings. do the tubes to eliminate that issue
and see what happens. are you burning oil? post back if the oil is on the threads again and we will help from there.C8-)If it was on the threads but not the tip/end, the oil got there when you unscrewed the plug so I’d say it’s from the tube. As for how long to wait for the RTV to cure, there are so many different kinds that you should look at the label and see what they recommend for what you bought – I’d say at a minimum wait at least an hour.
Here the pics today I removed the spark plugs… All 4 spark plugs look just like this…
what is wrong? I do loss oil consumption little each time I drive 40 miles… do you guy think valve seals bad or I have bad ring?
If you suspect you are burning oil, i would recommend doing a compression test as well as making sure your PCV system is working as it should.
Do you notice any blue smoke when driving? Usually when valve guide seals are leaking, you would see the blue smoke on deceleration.
today, I recheck and there is no oil in spark plug tubes at all after replaced all spark plug seals. but i still burn oil and the pic above look like oil burn around the double tips… please comment what can be wrong… valve seals gad or ring bad? if I do compression test, will that reveal ring bad or good.
all 4 spark plugs has the same thing all across.. see attached pic above…
What set of tool do I need to buy in order performing compression test?
Any website to buy complete set compression test kit?
Thank all the great comments….
today, I let the car in parking (P) with engine idle and raising the RPM up to see if there is any smoking goes out the exhaust pipe. i did not see any blue smoke but i know there some black smoke come out the pipe when i raise RPM up…
black smoke come out is normal?
however, I took my hand and touch exhaust pipe where the CO2 exit. i see there is smoke deposit around where the exhaust escape… is this normal? or sign of valve seals worn…
You can buy a good compression gauge at Sears, but any parts store will have one too.
A (wet) compression check will tell you if the rings are bad, but it will not tell you if it’s bad valve stem seals.
Like Dreamer said, one sign of a valve seal problem is smoke on deceleration. The other is a puff of smoke after the car sits for several hours, like overnight.
what precaution do I need to take when performing the compression test? disable the Fuel Injection fuse right? do I need to remove all 4 spark plugs before I perform compression test…
anyone has a link how to perform compression test? this is my first time of doing the compression test…not really familiar ..can someone show me in right direction diy or youtube compression test…
tomorrow, I’ll call around which store has..and I’ll buy one.
