Hey everyone, I've confirmed (I think) that my engine is a Goodwrench 350 with casting number 10066036, Hecho en Mexico.
I'm trying to sort out the dipstick tube situation as I believe this is the source of an oil leak, from the wrong one being installed. From my research it appears the passenger side dipstick on this engine is:
Main tube: GM 12552920
Dipstick: GM 10190942
However, I'm not sure if this requires a two piece upper and lower tube. I found some reference to:
Lower tube: GM 3951600
A few questions:
Thanks!

A few questions:
- Does this engine using the passenger side hole require the 2 piece dipstick tube?
- Do my part numbers look correct?
- Is there anything else I should know about this installation before attempting it, like is high temp RTV good to use?
Thanks!
