Hey guys,
Just wondering if anyone has had any similar probs and any advice? Engine began making a deadened knocking noise and upon inspection it seemed as though the noise was coming from the air filter/intake and my first thought was a valve except that she was idling fine. Went straight to the workshop and my mechanic upon further inspection found that a shim had displaced and in turn both the shim and the coinciding section of the camshaft had deteriorated beyond repair. It was blocking an exhaust valve which caused the pressure to come back through the intake hence the location of the noise. The shim had worn through( imagine it being countersunk with a 25mm drill bit) and the section of camshaft rounded down. That seems to be the extent of the damage. Now 1 last problem we are having a hell of a time finding a replacement camshaft. My mechanic recommends a 2nd hand one so that's it's slightly worn in. If anyone has one or knows of someone that does it would be greatly appreciated. Also any tips or pointers would be great.
Melbourne area
Thanks
Mick
