They seem a litle low perhaps but not that bad.

 

I'm sure someone that knows better than me will be along soon.

Plugs out, throttle closed, engine out.

try with throttle open, but looks a bit low as manta said on one cylinder in particular, not real bad but worn.

I was worried someone would say that, I've put the bell housing back on the box in the car :smash: Would the result be a little higher with the throttle open? The engine is only a tempoary one I'm putting in while I build a new one

Bung it in then! :wack:

i was going to say, bung it in if its a temp one, if the results were less than a hundred per pot i wouldnt bother!

 

im driving a courtesy car whilst my company car is in for some work, whilst driving it home it was missing like a *******, so checked all leads, removed plugs and tested it cyl 4 has baely no pressure LMAO 140k mile ford though would explain it, i told the company its not a ****ing courteous car!!

erm with all the plugs out, the balance bar is off so NO NEED to open the throttle
