Hey everyone I pulled my driver side spark plugs this morning to try and see if any of them had oil on them due to a bad valve seal. Im going to post a picture of them tell me what you all think? One of them seems quite a bit more corroded then the other 3.
Starting with driver side front

Now I installed these ngk tr55 about 2k miles ago maybe 3k. I put them in right after I did a 228r cam swap. The car runs good, it put down 385rwhp with stock heads.

Did you replace the valve stem seals when you did the cam? The one looks like it has excesive buildup for 2k miles

I did not replace the valve seals it does burn oil so I was Trying to see which one was leaking. Is the excessive buildup pointing to that plug as the culprit?

How many miles does the car have? What cylinder did that plug come from? Sounds like the seal needs replaced cuz it's worn and oil is leaking by it into the cylinder. How much oil is it burning?

The car has 153k miles. It seems to burn about a quart every 800-1000 miles.

Yea you should have replaced those seals when you were in there.. Now you need to replace them or you will keep using oil and those plugs probably won't go way to many miles before they get fouled by all the buildup

Leaky valve seals usually has wet raw oil on the plug threads when you take it out. Were they all bone dry when you took them out?

Shouldn't I be fine by just replacing the seals that affect that cylinder with the spark with build up?

Yes they were not wet. I just pulled the driver side this morning. May pull the others later. Well a couple may have had some wet on them. But I havent started it today if oil was leaking on any of them wouldn't there have been oil on the tips of the plugs?

Here is a question. When you let your car sit for a day or more when you first start it up does blue smoke come out the exhaust?

trey1010

iTrader: (3)

Yes usually even letting it sit for much less time. When I start it in the morning it usually smokes some and then when i drive it stop and restart it maybe smoke some
More

I'd change the valve seal on the 2nd one for sure, and keep an eye on the 4th.

Than yes you have valve seals leaking. Really it would be smart to replace them all while your in there replacing the one. It's not like it is a horrible thing though. You will be fine for awhile as long as you keep the oil level good. At some point though I would just replace them all

yea the 4th plug picture appears to have some liquid at the last thread closest to your fingers and due to what youve said id replace em. when i had the heads off my car i replaced them kuz the cars got alot of miles on it and it never really smoked but oil consumption went down dramaticlly

Oil is 45 octane... better take care of it before you detonate the **** out of the affected cyls.
