thanks matt
well i've not really pushed it what with just been put back together
there is more vibration thru the car from the engine and it sounds deeper thru the exhaust (you can see at the start of the vid)
and its running 5w30 oil which is no good for this engine its too thin but it was all dad could get when i sent him out to get me 10/40 so its not as quiet as it could be
its still just an astra 🙂
form the test drive the mid range speed has changed and it does accelerate 30-60 alot better
