Mk2 cupra compression ratio

[_chris_]

Evening.

Looked around but seem to be getting mixed answers on a search for the compression ratio of the mk2 cupra.

So does anyone know the compression ratio of the mk2 cupra.

Cheers.

No idea if this is what your looking for lol

I done a compression check on Sunday there and got 12.5bar across all 4 cylinders which is bang on.

Looking for the compression ratio of the actual engine.

Ive got a bit of a issue with the car. I've just done a compression test and let's just say its not the best.

Cheers. I kept seeing 10.3:1 and 10.5:1 I assume these must be for the FR/ k03 engines

What were you compression results ?
Did you do this with engine cold , then warm ? Or just one or the other ?

Don't think it really mattered on mine if it was cold or hot!

I had horrible a misfire, oil on the top of the engine. Cylinder 4 was showing a misfire. Suspect melted piston.

Compression test came back as 17psi. Lol.

Head should be coming off next week to inspect the damage.
