Or, in other words, where is a first time engine builder most likely to go wrong?

Incorrect alignment of cam and crank timing marks.
Breaking the eyelet off oil pickup when installing the bolt through the case. Not checking deck height and confirming compression ratio. Not lapping the cylinders to the heads. Not using correct sealant for case. Improper installation of oil cooler seals = leak Incorrect setting of the crank end play. Not surfacing pressure plate mounting surface the same amount as the clutch surface. Not that I have ever done any of those things. (IMG:style_emoticons/default/shades.gif) |

Not surfacing pressure plate mounting surface the same amount as the clutch surface. Is grinding the ridges off the flywheel bolts a suitable work around for this? When I had my flywheel resurfaced decades ago, I asked them to surface the mounting hub to match but I don't think they did it. I decided to grind the bolts to be sure I have clearance but haven't run the engine yet. Is that going to bite me in the butt? Also, it's been a long time, but it seemed like installing the distributor gear was a little tricky. |
