Hey guys i just decided to change out my spark plugs because my car has not felt so powerful as it used to. All of the plugs are oil fouled, and I can see oil residue coming from under the intake manifold, any information would be great, help!

mods? mileage?

 

headers, kinetix intake manifold, and intake, 48,542 miles

 

any access to a compression tester?

 

Unfortunately no. Bought the plugs on friday because I just wanted to do some normal maintenance today now im worrying.

 

I am worried it's your rings, need to test to find out.
how low is your oil?

 

I just changed it recently 5 quarts. I can never tell with the stupid dip stick we have, it always picks oil off of the dipstick tube

 

did you put the plugs back in? I think checking to see how fast they foul will give you an idea of how bad it is....but you must get a compression test.

 

any chance you overserviced the oil? drive near red line often? went a while with low oil (more than a qt. low)

 

Well I don't believe I overserviced it, though I do drive spirited sometimes. I guess I will just change the plugs and check them next weekend, appreciate the help though really, thanks.

 

get a compression tester. good luck

 

Can you do a compression check yourself or do you have to take it to a shop to do it?

How easy is it to do and what is needed or have to be disconnected from the engine for the tester to work?

 

you can do it, the tester replaces a spark plug (one at a time). you dissconnect the spark for the engine. just using the starter motor to turn the engine over will give you the reading.

 

i had some blow by at 30k miles on the 2 back plugs...but it was normal, we pulled 2 other cars and they had the same signs...

 

Could be tube seals are leaking too. I had a few plugs with some oil on them.

 

that's what I was thinking too.
