Burning Oil
I've been having an issue with burning oil for a few weeks now. So in an effort to figure out where the ---- the oil is coming from I did a compression test. Before I could get started I noticed that on cylinder #4 there was a good amount of oil just sitting on top of the plug inside the tube where the plug and wire sit. (Don't know what the ---- that is called). Obviously the oil isn't suppose to be there. The compression check came out
#1 #2 #3 #4
180 180 180 170
I've never had this problem before and the only thing I can think of is that oil is seeping down through the threading and into cyl#4 causing me to burn oil. If thats the case then how the ---- do I fix it?
BTW its a D16Z6

Is this a boosted or Na d16z6?
Do you run the engine over 6k rpms all the time?
Does the valve seals look ok? How many miles is on the motor?
What does breather passages and PCV passages look like (are the clean)?

Re: Burning Oil
id pull the vlave cover and replace the seal for the spark plug tube.; id also consider the vlave stem seals, but that would just be a reason it smoking, not why you have oil all over the inside of the plug tube.

Re: Burning Oil
Turbo
192k miles
95% of the time I drive this it doesn't get turned past 4500rpms
I haven't checked the valve stems (because it was late last night when I decided to do the comp test) and the pcv system basically consist of an open tube from the VC pointing to the ground and the other pcv valve has been gutted and pointing at the ground also... yea i know my pcv system sucks. So you think this is the main point of concern here?

192K on the clock is a bit though. Rebuild plus vitaras is the ------- win.
5% loss in one of the cooler cylinders isnt a concern. Carbon buildup is though....
