how do you go about install connecting rod bearings .and if the connecting rod caps have grooves can you reuse them
This is no longer my specialty and I haven't replaced bearings for years, however if you are doing this on your own and you don't want future problems, I would highly recommend the use of a service manual meant for that car. This means no general information from the repair books you get in book stores and I have even found inconsistencies in Mitchell on Demand.
Even when I did engine work, I relied only on one form of information and that was from the source, the factory service manual. this included installation of components such as bearings that were critical as to where the oiling holes were installed, the torque specs, no matter what it was. In stead of paying hundreds and doing long searches, you should be able to find all the information you need at http://www.alldata.com. The cost is $30 for the first car with others costing $16 a year for a download available on your computer for a year, covering not only the engine, but everything related to the car. This is where I go for when I need specifics on a vehicle repair.
When it comes to take down of the lower end of an engine, they are all pretty much the same, but if you don't want a future failure in your installation of these components, you have to use the factory information as it relates to the engine in a 1994 Cadillac, or all your work may be in vain.
