My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
My info is limited on your model here but I see no one else has responded and thought I would see if I can help here.
From what you have described here this sounds like a restriction with the oil flow causing this issue.This can be due to something being put together incorrectly or a gasket that isn't lined up properly.I would re check the work that was done to see if an issue can be found and if a fault is found it will need repaired.
Thanks Pete
