My ex Astra GSI 20XE turned up today on a pallet. I set about unpacking it to change the cam belt before fitting it in the Astra CD.
Found it had the 12 point little splined bolts holding the crank pulley on, I dont have a bit for that as my other 20xe has star bolts on it, down to the factors to get one.
Tried to undo them and found the first 2 I tried had been rounded off or rotted off splines.
Oh well out with the drill.
Once drilled with a 4 and 6mm drill bit down as far as the pulley flat face a smart smack with a drift knocked the heads off.
Removed the pulley and just wound out the studs by hand.
M8 stainless cap heads are going back
Hmmmm....cam belt cover off and what do we have here.
Belt and braces or should I say tensioner and spring, its quite an early engine number so I wasnt expecting the spring too.
Looked harder and I could see oil from both the cam cover and camshaft oil seals which has been running down behind the cover back plate and dripping off the sump.
So my quick cam belt change has already changed into a full blown oil leak hunt.
I guess I better check the hoses and sort the cam cover breather out while I have it apart as maybe pressure is causing the seals to let by. Engine is reported to have 80K ish on it.
Should I do the crank seal while I am there? Is the main bolt a once only use job or can I reuse it?
