Hi, does anyone have any tips for the rear main cap side seals (L16 engine)? i put the silicone in the side corners, set the main-cap in place 1/8 above bottom then inserted (pushed) the rubber seal down to the bottom (lips to the block), snugged up the cap and then tried to put in the metal shims (nail?) in between the cap and the seal (as the tom monroe book said with bevel toward the cap) but only got 1/2 way before the metal shim bent because it was so hard to push. So purchased a new seal kit and wanted to hear any tips before i re-tried to install. Thanks in advance for the help. Cheers
