blue98ls1 Posted September 23, 2008 Report Share Posted September 23, 2008 I started working on my 82 Porsche 928 again, I really want the engine back in the car before winter. This is my very first engine rebuild to this degree and I have never done timing on a car like this, my experiance with timing belts have been on my SVX's and they where incredibly easy to do... unlike this... so I need some help or advice or something from someone who really knows timing. Basically I got the engine back together, I made sure when I put the engine back together that piston #1 was flush. Someone had told me that would ensure the engine to be TDC. Well I moved the cam sprockets to try to get them to line up and it seems when you turn them to the marks they are in a high spot and the slightest touch they turn and drop. (best way I can explain it) I am guessing it is not suppose to be like that. Quote Link to comment Share on other sites More sharing options...
Guest mitsumodder Posted September 23, 2008 Report Share Posted September 23, 2008 it may be that the valves are slightly open at TDC. I am a master subaru tech and in a WRX motor when at TDC one side of the motors valves are "loaded" and the other are closed. it is going to vary pre vehicle. I would get a manual. or at least set the pistons all even in the middle of the cylinders if this is an interference motor Quote Link to comment Share on other sites More sharing options...
