Why is these happening to me - 3 turbos

[danieltovar]

Well I have 6 bolt built with shaft elimination kit. Ported stage 3 and 2mm size valves. When I put it in my car after 1 month in half my car started smoking little sometimes smoke then when everything started I was connecting my knock sensor back cause was not making connection bad wires. Then I turn the car back it started to smoke and from there it smoke bad. The turbo had zero play and took it of and order new one from Austin, when I put it right away smoke crazy. Then I took it off send it for inspection and put another one buy from dsm local and change my fed line to the head and when I started the car it smoke right a way alot. Well what the f I have the stock oil drain no kinks and fed from the head why. tire of these car, what's next I have an new build motor and turbos leaking from the oil seals. Another thing I did was put the bov to little hard. Help please before I throw the towel on dsm cars

On one side was 132.02 and 132.02 (timing gear side).
On the other side was 131.98 and 132.10 ( thermostat housing side).

I double measure the head and it was not right, however, it was resurfaced with a polish finish look.

What do you guys suggest.

That must be im MM the measurements.

132.02 x .03937 =5.197

The head thickness is good.

Guys from the info and pics could these cause the turbos to leak oil?

Sure- your cylinder walls are grooved to hell. There's no way the rings can seal properly, so combustion gases are entering the crankcase and preventing the oil from draining from the turbo.

Ok so the head is good to go then thanks. I problebly just take it like Miguelmcv said to make sure is not crack, or have any leak.

Ok so that might be my problem those pics tell You gases on my crankcase, so i will know remove my block and build it again and safe what i can.

So the thickness is good, But how about not being equal in thickness from one end to another?,. It means that the difference between the gear side and the thermostat side thickness is minimal, so it is considered even?.

I am agree with your statement, But i'ts just curious that we did a Leak down test and came up with 5%,, I do know too that some times there are inexplicable thing that happens and we just have to live with that, It might be one of those things, Unless the Leak down tester was not accurate, But I doubt it, because we couldn't even hear any air leaking, It was so compact.


Thanks for all the help guys.

131.98 x .03937 = 5.1960

132.02 x .03937 = 5.1976

.0016 that is about half the thickness of a sheet of notebook paper

That close, I would call them equal

I see, I thought it was off, but it's because as you stated before, I measured in MM, which that make the numbers more dramatic.

Thanks to clear that up.
