Reply With QuoteIf it's a TDI then you may have a snapped belt? I think I've heard of the 300s breaking the shaft and/or rockers themselves.
I think it would be a thing that would need looking at since it will have been changed/removed for your head work.

yesterday the landy was running like clock work with the new head on it, today it makes a god awful noise 50 meters down the road, get it home to find it has snapped the rocker shaft between cylinders one and two? whats this about, fatigue coupled with the new head? bad luck, karma everything was done up to factory specs, valves clearances where spot on. cant work it out ggrrrrr

nah the belt isnt touched when doing the head, its a push rod motor not overhead cam, plus the belts new. done about 5thou kms
AT REST
Broken bolt, either over or undertightened somewhere in the past, or a stripped thread in the head. I read somewhere that torquing used rocker shaft bolts to full spec can be hazardous.
Master
no broken bolts any where, maybe its like you said about full spec torquing on used rocker shafts, no stripped threads etc, everything went together swimmingly.Originally Posted by bee utey

Supporter300TDi is not an OHC motor either but the timing belt drives both the injector pump and the camshaft, if it goes you end up with broken rockers and bent pushrods, at least
Master
yeh but when turning the crank by hand the other rockers work fine, checked all the push rods and they are fine, putting it down to fatigue, new one arrives tommorow
