So today after the absolute result in the MOT test....
I decided to look at why, for a 3.2, to use TheBoy's expression, it felt as flat as a witches tit. I also thought I'd look at where the oil leak was coming from at the front of the engine.
I could see the oil pressure switch has been done in the not too distant past, probably to try and cure the leak onto the top of the sump at the front. Having cleaned off the oil and it coming back I knew it wasn't that.
I therefore suspected the front crankshaft oil seal. In light of the multirams working well etc, I also suspected the Vauxhall dealer had murdered the cambelt installation, resulting in the flat performance.
So, off with the plenum, bagpipes, inlets stuff blah blah blah.
Upon checking the valve timing, on the cambelt setup, it was WELL over a tooth out on all cams. It's no problem for me, but if I'd paid Vauxhall the amount they had been paid, and this was the result, I would have been absolutely fuming:
So this was with the crank locked at TDC - this is over a tooth out!
The above was the same across all 4 cams, so I won't post all 4 pictures, you get the idea.
Vauxhall want SHOOTING!!
They have also vastly over tensioned the belt. It's done 15k only, yet grease EVERYWHERE through probably excess pulley wear due to incorrect fitment. A brand new cambelt kit will be going back on, I don't trust this one.
Anyhow, here we are with the entire cambelt kit off:
And, as you can see, the oil is clearly coming from the crank seal, now the sprocket is removed:
And here is the offending item:
And here you see the oil leak before it was taken apart (you can see it on top of the upper sump)
So tomorrow, I pick up new crank seal etc etc from dealers. As and when I feel up to it, I'll put it all back together and she should now be oil tight!
Goes without saying, full service and extensive breather clean will occur at the same time.....
