Show me your engines compression..

[Righteous]

Hey all i been having issues with compression and would like to see how it compares to the mileage of the engine as feel this will be helpful to lots people .

So all you who have done a compression check state the car,year,engine,mileage and the compression results .

Ill start.....


First
Renault Clio 2001 1.2 16v D4F 130000 miles 105 PSI ish across all 4 cylinders. ( I carried this out with the engine warm and throttle open with the TPS sensor dissconnected)

Second
Nissan Skyline GTST 1993 120000 miles 120 PSI ish across all 6 cylinders. (Again engine was warm throttle wide open ECU dissconnected)

Engine cold 110 PSI ish across all 6 cylinders.

When i did my old 172 @ 132,000 they were all in the low 160's psi iirc

What is healthy compression on a 1.2 16v anyone know?

 

[Righteous]

Yea that sounds good to me russ and im unsure of the 1.2 16vs compression for been healthy another reason why i started this so had something to compare it against im pretty certain 105 PSI is very low thou.

you're doing it wrong. Open the throttle fully

 

[Righteous]

Yea throttle was wide open on them both.

 

[cliobritt]

155s but a 135 at the fly. So went across to Surrey Rolling Road for a test and it made 159 horses so not a disaster just pretty average (the tester called it 'a bit leggy'!). Still it's done 162,000 miles.
