Audi Repair Questions? Ask a Mechanic for Answers ASAP
I was in the middle of debating the free unlimited trial here when I saw this question. How much can we chat on here before it cuts me off?
Old belt is installed. A little back story....
I have several bent valves on the 3.0L motor that came in this b6 and I decided to swap a 2.7tt from an 01 s4.
The engine came from a reputable place with near perfect leakdown and compression.
Unfortunately when I got the engine home a tow strap broke and the motor dropped 3ft breaking the right valve cover and rear cap. I was worried I messed up the whole engine but it looks to be those two things only. I have been told by several people that most likely the inside of the motor is fine.
I have the engine on a stand now and have begun the process of a timing belt change. I have removed the acc belt and am at the point of hand turning to TDC. I can move it a little but I don't want to force it.
Most things I have read about stuck crankshafts involve bent valves and I am worried
The rear timing covers (inside)? Valve cover is off on the side that broke, coilpaks and plugs are all out.
no. So with both valve covers off I can move the crank back and forth the 90 degrees and see if all the rocker arms move?
already removed spark plugs and no change. I will see about the moving arms
I have the valve covers off and I can see that the cams are moving at the same rate. Their are also markings on the cam chain and marker to show that they are lined up.
The point where it gets hard to turn is when the right cam chain tensioner seems to be at it's peak height. Is there greater resistance when it goes from high to low? As in, am I pushing hard enough?
