Hello everyone, got a question hope somebody knows answer to. Sorry its long.
Car is Megane II 1.9dci 130bhp 2005 facelift F9Q engine.
Ok, so last xmas went out to a show, moved the car after as was meeting friends and when came out realised there had been a really bad cold snap.
On way home later didnt notice at first but after couple of miles thought car bit noisy and realised loud knocking. Have another car so only just got round to looking at this one. Unsure if big ends or if its jumped a tooth on cambelt (overdue change), so first job check the timing. Read all the threads and got a TDC pin (with the screw thread).
My question is, is there more than one position in can go in?
Only place it seems to be able to screw in all way seems to be incorrect as cant turn engine without it hitting (presumably a valve) somewhere after about 90 degrees of the crank. Read online somewhere that the mark on end of crank is at approx 7 'o'clock when TDC. Confirmed this by using thin screwdriver in glowplug hole to find TDC and it seems to be correct, however the TDC tool wont go in as far as the thread in this position. With this setting (7 oclock) and cam sprocket on its mark, can turn engine fully.
To get the pin screwed in crank has to go till marker is about 8 oclock.
http://ift.tt/1I4eZ1C If I then re-align cam sprocket to its mark, engine wont turn more than about 80 degrees before hitting something and locking solid.
Any ideas?? Any one used TDC tool to set and can remember position of the marker? I'm fairly sure it must be the 7 oclock position as thats where number 1 & 4 are TDC using a rising marker, but why wont it go in here?
Looking at drawings in all the guides it looks like it sits under a flat spot on the crank rather than going into a hole, and that appears correct as there is a bit of movement in the crank rotation until its screwed all the way home.
I've done the start just before cam marker, move crank tiny bit at time pushing TDC tool in and out, and cant find another position for it, so what am I doing wrong? The only way to get it to miss valves would mean with the tool all way in the marker on the cam would be incorrect for TDC.
All suggestion gratefully accepted!!
