So I have boosted. My shitty junkyard motor for 17k km.
Its now running like **** and feeling rubbish. Vibrations. The lot.

So, leak tested :

1: 20-25%
2 35-40%
3 20-25%
4 20-25%

Now how much leakage is **** on these motors? Is this enough to give no power past 80km/h? -> 11.8psi on TD04
Or can i expect more than just ring damage?

No blue smoke, just blowby 11/10

Reason for the leak down test was I used to reach 123km/h on my favourite Hill... I struggled to hit 85. Just no power.

Note that the junkyard motor came with lovely compression figures of 155-178. They lied and said it was 198. From a ******* porsche wrecker.
Cheers

 

Maybe buy another motor, tear down, hone, rering, and try again?

 

Rather than just go by leakdown numbers, when you do a leak down test listen for where the air escapes to. You can use a length of hose - one end in your ear, the other to probe. Listen in the throttle body for bad intake valve seal, the exhaust for bad exhaust valve seal, and in the valve cover for bad ring seal. You can do this for each cylinder, and decide if any one are "too bad" for your liking

 

Yeah rings are gone.
Hopefully no other damage. I'll find out this weekend.
Going to lap the valves and check clearances. I have another head so I'm sure I can build one decent one out of both.
