Hi All,

I have a new engine ready to replace my hydro-locked and subsequently damaged one but I want to give it a good going over before I fit it.

I have a cylinder leakage tester and a compressor and I am wondering what percentage of leakage on a cold would be considered healthy for this engine.

I know it is usually under 5% when the engine is hot.

Cheers
James

I've done a cold leakage test on a fairly new F22C once. Results were 1% leakage on all cylinders.

I've also done a leakdown test on a semi-warm F20C w/ 80kmiles. Results were less than 2% leakage.

Just what I needed, thanks

Or a severely worn engine with 133K, like mine had 2,3,5 and 12% leakage. Rebuilding as we speak.
