Considering whether it is worth attempting reconditioning above engine in our workshop. The engine has run a big end. Most of it looks doable and would send the head away etc, but reading the workshop manual it goes through the procedure for reaming the small ends. I don't have the necessary reaming tools or knowledge to ream them out. With modern manufacturing techniques, will the small end bushes be supplied at sufficient precision not to need reaming or do they still need reaming out after fitting? I don't recall reaming the small ends when I rebuilt the Lambo engine two years ago. Just fitted new ones and they seemed OK. Any other difficulties or peculiarities likely to be encountered? Just asking before I rave it apart. Tempted to just take the offending big end off, emery the journal and fit new shells and leave it at that like we did on the diesel which ran for many more years on light saw bench duties. Thanks.
