Opel Rallier since 1977
Likely the rods bearings are .25 mm over, which is .010" oversize. Never seen or heard of a .025" oversize.......OGTS lists numerous oversizes.Thanks for all the chat and help folks! I really appreciate the assist as I go through my first Opel build.
The update for today is that I broke down the whole motor (took the engine out yesterday).
So the news is that the crank is already .010 over on the mains and .025 over on the rods. I am hoping that the crank is alright because I am not sure if there are .030 bearings or not? Gotta call OGTS if the crank needs to be turned and see.
I also had an unfortunate accident where I tipped the engine over so I could lift it into my truck and the oil dipstick came off. I am assuming I broke it, but I am not sure. I am going to ask the machine shop to take a look at it and see what they can do. I am doing the work solo so manhandling the engine is kind of weird when it is off the stand.
Anyhow - tomorrow the thing is off to the machinist so I can see what it needs and then order parts! I will make sure to take pics when I get it all back for the build.
In the meantime - Is an aftermarket cam worth it? If so, what is the favorite here for improved performance and keeping drivability. I have a 4 bearing cam.
As for cams, OGTS does not currently list what I would consider their mildest step-up in cam size. So the only choice I would consider is their 6059. Don't overdo it, unless you want poor low RPM torque, and loss of driveability.
