Compression test on cold engine results

**Velox** · 08-08-2016 03:28 PM

Ok after my coolant leak/overheating, the car has been driving normal so far, no coolant loss etc
Still wanted to do a compression test.
I warmed up the engine only a little bit and struggled so long with the fuel pump relay that the engine was cold again by the time I finally got to the compression test lol.

Should I be worried about the 145 low 160 high difference? the max spread was 10% right?

1 150
2 155
3 145
4 145
5 150
6 145
7 155
8 160

Seems to be fine to me, anything more than a 20psi difference is where you start to have issues.

Did you use the proper coolant? (G12) I remember you stating you don't have easy access to parts?

Ok thats a relief, and the 145's were more like 147 and the 160 more like 158.

First I filled it with orange dex cool, it said for audi on the package. Then I looked it up on internet, saw bad stories.
Luckily there's a volkswagen dealer on the island that sells g12. Flushed the dex , all good now.
