Well I have done the engine oil change but Halfords didnt have enough gearbox oil so that and the transfer box will have to wait. The tappity engine definitely sounds better to me!!
Looking under the gear box there is a round hole which is in the position I would have expected the gearbox drain plug to be in. I hope it hasnt been just left out?
this is probably where the wading plug fits ...it made me think there was something missing when i first looked.
and my rocker cover gasket went on the back corner too , dunno if it is a common fault on these engines ..... watch for your manifold bolts coming loose giving an exhaust blow at the manifold gasket too ....
Cheers mate. Changing the engine oil has made a definite improvement to the tappityness!! Thanks for the oil info - much appreciated.
I will address the rocker cover gasket as I deffo think this is where the hiss is coming from. I guess if I take the oil filler cap off the hiss should disappear if its the rocker cover gasket.
