Engine Gone?

[R TUNE]

I did a static compression test on the weekend and came up with the following results.

CYL 1 100psi

CYL 2 100psi

CYL 3 100psi

CYL 4 100psi but leaked to 0 psi in 1min 40 sec

CYL 5 100psi but leaked to 0 psi in 30 sec

CYL 6 would not hold above 60psi unter cranking.

what gets me the eng runs smooth and is still making decent power. It goes to the tuners on tuesday as i have fitted a bigger turbo. Just wondering what people think of the results.

Spoonfull of oil in the spark plug holes and try again.

Doesn't look good tho

Yep, oil that cylinder up...

Engine is warm or cold?

[R TUNE]

Engine was warm as i had changd the oil first.

[MagicMikeZ32]

Wouldn't bother tuning. Chances are you've got bigger issues

[StevenCJR31]

yep, engine gone

Double check how you're doing the test.

Otherwise it is not a good sign.

Or get the tuner to comp test and leak down test before he does anything else.

I spoke to the tuner about my results, and after having it on the dyno he believe the valve steam seals might not be sealing properly. Reason behind this was smoke on back off, even tho all old oil should be out of the intake system (due to blown turbo). The car made 165rwkw at 12psi, with a boost controller that was not holding boost at the desired level, 14psi. (it top 16psi and bleed of to 12 psi). We will be investergating further.

I don't think that explains the low comp on cylinder 6. Valves, head gasket or rings are the causes. Isn't 165kw on 12psi 25det turbo low?

Sounds about right to me

The power out put is about right, considering im in darwin where the tunning temp was 35DEG and 70% humididty that day.
