<FONT face="Arial, Helvetica, sans-serif">Hi,</FONT></P>


<FONT face=Arial>I was wondering if somebody could assist me. The camshaft bearing bolts (16 total) on my 1988 190E dont seem to hold the torque. A few days ago I replaced the camshaft.I torqued down each set ( 4 sets) ofcamshaft bearing bolts to 15 ft-lbs as stated in Haynes manual.After torquing down all 4 sets of camshaft bearings I notice that the previous ones needed to be torqued further. I closed the valve cover and drove the car for a few days. It runs beautifully smooth. Not satisfied I reopened the valve cover and found thatsome of the bolts have loosened and need to be torqued down again? Some questions:</FONT></P>


<FONT face=Arial>1. Is15 ft-lbs the correct torque?</FONT></P>


<FONT face=Arial>2. </FONT>Is there another proper procedure to torque down these bolts?</P>


3. How do I ensure that the bolts hold the torque as specified?</P>


Any assistance would be much appreciated.</P>
