Please look at the pics of these spark plugs...they were put in back in August 08 and I removed them Saturday 17/09 from my 95 4runner 3.0 v6 auto and give me your opinion of what is going on with these cylinders..My 4runner vin number didn't have a head gasket recall per the Toyota TIS site...so What do you think is going on?..do I have water entering the combustion chamber?....my engine runs fine and I have no so called White somke coming from the exhaust but my plugs smell like some kinda rubbery radiator hose I guess I would call it any advice will be appreciated...sorry I did have them in order but my dog jumped my when I came in the house and the plugs went all over the floor some pics not as clear as should be sorry

















should I sale this runner? while it is still running. I have had other problems with this 4runner and wonder it I can spend more money on it and time lots of time is it wort it??? and if I do decide to sale it what is it worth?.. need some work in but is vary clean.......maybe I'm jumping the gun here

How many miles are on the engine?

if you have a haynes or chilton manual (and you should) i think on the back page it shows spark plug colors and causes.

Time for a head rebuild?

All my plugs where like the darkest one on the pics, the one to the right, when I removed them, after 2 years....although, they where b*ch super 3...the plug at the 6th cyl was almost carbon dust....

time for a 3.4

jsn_stockard....there are 176,334 miles....

desertcox05...I do have a haynes manual and I will go look up spark plug colors ect thanks for reminding me

so what is going on in the combustion chamber?....I can't smell any sweet smells of radiator fluid coming from the exhaust.
I also checked the engine oil and it looks normal no signs of water in it...take a look at these picks of what is in my radiator.The red stuff must have been put in by the P.O..... and maybe he thought it would seal up what ever was going on long enough for him to sale it and I guess it worked the way he wanted it to.....Because I bought it and now I have to deal with...

How do you have coolant in the overflow reservoir and not in the top of the radiator?

Also, isn't red the official toyota coolant color, or was it pink?

#6 plug is seeing some oil. Valves or Rings. Other plugs may be seeing a little oil, or your spark timing is slightly off. Leakdown is a good place to start.

Coolant does look nasty. Corroded radiator? Mixed Coolant types? Time to flush and replace either way.

If it's otherwise running fine, and not burning much oil, just run it as is. Save up for a 3.4 rather than repairing the 3.0.

DupermanDave.....coolant is in the radiator in the pic all you can see is the red stuff kinda pasty.....I really don't know if Toyota coolant is red like I have in the radiator. do they have red coolant?....this stuff has a paste to it I found that out when I drained it from the radiator and flushed it last week.I doesn't look as bad now because of the flush

buckz6319

allnmstkn313........I agree...and the timing is a little advanced maybe I should retard it back to 10 degrees like manual states...and would like to have the 3.4 but not going to happen any time soon...thanks for the info

x2 - the only plug that looks out of the ordinary is the one on the far right. I x2 the compression check too - if it comes out OK, I wouldn't worry about it.

x2 for the coolant flush/fill ... looks like maybe they had put some stop-leak in there, which is OK for a temporary fix, but can have negative effects down the road (namely plugged heater core). Have the coolant system flushed by machine and fix any leaks properly.

If you haven't had the head gasket recall done, why don't you make an appointment and take it in? They will freshen everything up and it won't cost you much since they are already in there ...

what would be nice... is that you don't move the plugs around when taking the pics.
And the first three pics don't look anything like the others.

I may be blind though.

If it was me I would replace the rediator and flush the inside out, and always use green coolant... Also on the spark plugs, use iridium spark plugs. They are good in the cold weather and can take the lowest voltage to spark.

little tip on reading spark plugs black-overfueling white-running lean oily-well burning oil lol chips out of them-detonating yellow ring around the ceramic- plugs leaking compression look down in the cylinder with a good light if its really clean and u havnt just had it cleaned odds r your leaking antifreeze into the cylinder however its kinda hard to tell but it looks like rust build up in the antifreeze have u flushed it a couple of times better pics r a must to help

buckz6319

abecedarian....your not blind ...i can see what you see just bad pics but I did try to move the plugs around for a better look at the ends and on both sides.
I will try to do better next time but my camera doesn't take good close up pics sorry for the blur..
