Hi guys... first post here so hope you can help .
While checking the valve clearance on my 03 115 JTD ELX at about 60k I stupidly used the cam shaft nut at the end to turn over the engine, rather than clear the crank and use that :bang: It all seemed to move ok, although the cam pulley nut tightened a tad...
All went well (ie valves all in tolerance) but then I started the engine there was an ominous BIG rattle at tickover, and I stopped tha engine immediately. So I've now stripped the LHS of the engine for a cam belt change (which is due soon anyway). I find that I cannot turn the engine on the crank nut to TDC position as it rotates so far and then there is a hard 'stop' which I can't rotate it beyond and I can imagine a valve stopping against a piston...
My plan is to change the cam belt for a new one and use the marks on it to make sure that the crank and cam are aligned (the cam is fine but I see no mark anywhere around the crank pulley on the surrounding casing...) So I will put the cam to the TDC mark and use the mark on the new belt to set the crank pulley position.
My question is - how hard should it be to turn over the engine on the crack nut, and is this the right procedure - so if I still cannot turn the engine on the crank nut does that mean a bent valve and head-off time? I do hope not...
Thanks for any help - I am most concerned...
