Engine Mechanical problem
1992 Volvo 940 4 cyl Two Wheel Drive Automatic 196000 miles
I have the B230F engine.
Regarding timing the enginge my Chilton's repair manual says " Rotate the crankshaft so the notch in the convex crankshaft gear belt guide aligns with the embossed mark on the front cover (12 o'clock position).&Quot;
My Haynes manual says " Align all the timing marks on the engine block with the marks on the crankshaft and camshaft sprokets.&Quot;
Both have drawings of the same engine, but indicate slightly different positions of the crankshaft, idler and camshaft alignment points.
Can you help?
