Default Oh damn! i think i found out where all my oil is going.

Ive been posting things about my oil disapearing in the past month or so and just today i noticed that my car has been smoking alot out of the tail pipe when ever i get on it hard or in mornings when i first take off so i asummed the worst today thinking one of my rings or ringlands was broken, i did a compression test with my car still warm and got these results average out of three test per cylinder
#3=161psi #4=162psi
#1=158psi #2=163psi
The plugs looked normal some white speckles and stuff but no oil
That being said im almost sure its my turbo seals on my vf-34 which only has like 20,000 miles on it Before i take my turbo off to have it rebuilt, is their any other reason that silver looking smoke comes out of my car and reeks of oil smell??? I would hate to take my turbo off any find out it was somthing else, Thanks in advance.

they do say that there is almost always some minor knock present, and that whether or not damage occurs depends on whether there is a severe series or single event.

Like Uncle Scotty says, bad sign if you have "salt and pepper" signs on the plugs.

Those little aluminum balls are persistant, so they may indicate a detonation event that occured several days ago. You can clean the plugs with a clean tooth brush and put them back in and make a test, then check to see if they come back.

You won't be able to hear high rpm detonation, too much engine noise going on. Big V-8's give a much more audible detonation than the stuff that will kill our engines.

Given where you live it might be a heat issue. You might be able to resolve it by putting in a cooler thermostat, and a low antifreeze coolant mix ( about 20-25% antifreeze to water with water wetter). If that does not fix it you need to look at one step colder plugs if your still on the stock heat range, and backing off the boost a bit.

Your most prone to detonation in the midrange rpms near torque peak, so high boost in hot weather and long pulls in higher gears near 4000-6000 rpm are a good way to break an engine if you don't have good fuel octane to protect you.

Take care not to flog the car hard when its really hot under the hood like after its been parked for 30 min or you have been stuck in traffic for a while, give it a couple miles to cool down on the road before you get on it hard.

In the summer time I either turn down the boost a couple psi or spend the money to bump the fuel octane up to the 95+ octane range.

salt and pepper look does not mean your detonating. When my car was completely stock the original plugs had those little white spots, its pretty common. Its the actual little silver colored balls that means your detonating.
Can I email my plug picture to someone because i couldnt get imageshack.com to work because the picture is 2.12MB. thanks

salt and pepper is what the drag racers call it when you see the silver balls or black spots from carbon blown off the piston crown on the plugs.

Could be turbo seals. Take off the DP and check the mouth. If it's oily, problem found. While it's off, you could check your shaft play too.
