I apologise for this long post not being about a Magna. It is about a fat relative though, the Mitsubishi WA Van.
Firstly, does anyone know the Mitsubishi engine type for the 2.4L petrol engine in the 1998 WA Van. Not the traditional L300 Express van but the walk-through version with a sloping front that looks like a Delica. It is definitely not the same engine as the L300 in the late 80's and early 90's. I'm hoping it may be the same as 4 cylinder Magna 3rd Gens. If so, their workshop manual may help. Gregorys/Haynes do not make a workshop manual for the WA Van.
Secondly, can anyone shed some light on the following problem because it does not make sense to us.
The van belongs to my brother. He is in Brisbane and I'm in Sydney so I haven't seen the situation first hand.
The cam belt was recently replaced but the workshop that replaced it is closed for the holidays. After it was done, the car was Ok for a while but in the last few days has been down on power and the engine vibrating badly. It turned out that the crankshaft pulley, which apparently includes a dynamic balancer, was wobbling badly.
My brother tried to take it off. First problem, it was very tight and he broke the central bolt that he thought held it on the crankshaft.
Second problem, the pulley still wouldn't come off. Apparently it was held on by four bolts spaced around it that screw into the cam belt drive cog. It now seems that the central bolt actually holds the cam belt drive cog onto the crankshaft and the pulley is bolted to the cog.
Third problem, after undoing the four bolts and getting the pulley off, the cam belt drive cog slid forward slightly. Its front surface is recessed, so he can't get at the broken bolt stub to get that out.
OK, he has bought a new bolt, so if he can get the old one out, it should be just a matter of putting the new one in and tightening everything up.
It is pounds to peanuts that it was stuffed up when the cam belt was replaced, but what could they have done wrong?
The bolts were all very tight. The cam belt drive cog is splined onto the crankshaft, so you wouldn't expect much play there. Yet from my brother's description, the pulley was acting as loose as Britney's morals. Well, maybe not loose but wobbly.
Since the cam belt is involved, we want to ensure the whole assembly is on properly this time. Also, being down on power might indicate the valve timing was affected. A cam belt that loose doesn't bear thinking about.
Any clues would be most welcome.
