Since my car started smoking a lil bit when the car warms up and I drive I decide to see what could be the problem. When it smokes the smoke is blue.
So I did a test here are the numbers

250
250
250
250

So I guess if these look right then it must be my seals in my turbo. Any thoughts
Motor is a stock b18c5

good numbers

 

up

 

try a leak down test it might show you some thing diffrent, i did a comp test on my buddy car and it was ok, but the leak down showd 65% in #4 and he was burning oil pritty bad, but the test only takes like 15mins and is a good pice of mind and can tell you alot about whats going on in the motor

 

the smoke is probably coming from the oil drain.mine smoked during warm-up until i moved the oil drain to the block.try running a lower oil level.the problem is that if you have your drain in the pan,the oil level is usually to high.

 

Not sure if I'm following what you are saying Danny.

yea those numbers are good, blue smoke is usually oil return/turbo related as stated above. aslo im not sure but i think a crappy pcv system can cause some blue smoke as well.

thanks for the help everyone.. Anymore

 

Those numbers seem a tad bit low to me. How much boost you running on it? I could be like the previous guy said about the pcv on the smoke but your copression rings could be a little weak also. May wanna do a leak down test just to be sure. A C5 is an expensive thing to replace if you take it too far.

 

whats ttt?

To The Top

 

 

wow ive never seen an oil return going to the block...

 

Will a compression or leakdown test actually test the oil ring? The top two rings hold back the compression and Ive been told the oil ring can have problems but not show up on a leakdown or compression test.

 

up

 

yeah those numbers looks pretty up there

 

I would like totap my oil drain into the block just scared about messing something up.

What is the advantage of doing this rather than just tapping the oil pan?

It is very possible that a compression test wouldn't show oil ring wear or damage.

The oil level would never be high enough to drain back into your turbo if your line is up there on the block. I think it is a great idea I'm just kinda hesitant.

O okay, seems like a good idea, but tapping the block would make me nervous

My beater is a 91 LS and it burns oil like its a 2 stroke. No doubt its the rings as the head is new. Compression test are 190 +/- 2 in each cylinder. Leakdown is less than 5% loss.

 

could get a moroso oil pan, baffled and has a high mount spot for the oil return line. They are a little expensive, but to tap into the block would require it being out of the car with it broken down, so cheaper than that.

If you get that oil pan you will have to put less oil in your car for it to be filled, a few people on this board killed the seals on there turbos by having that pan and filling it above the return. . .
