oil leaking
 

For the second time in less than a month the bolts holding the cam oil seal retainer have sheared off(the half moon shaped retainers located at the front of each head)Its only happens on the right hand side looking at it.The engine is a closed deck block with a v9 crank,CP pistons ,eagle rods and 1.6 cometec head gaskits.Any info would be greatly appreciated.....Andy
