Let me start out by admiting to not being very smart and to not having any idea of what I'm doing most of the time. This particular thread is going to be about my diesel engine in my dozer. I'm totally outside my comfort zone and really don't want to deal with the problem, but I have no choice. I have to fix it and need to do the work myself.
My 1989 Case 1550 dozer has a Cummins 8.3 turbo engine in it. I just rebuilt the Turbo and have learned that oil wont drain from it due to excessive blowby. In fact, the blowby is so bad that it's creating positve preasure and forcing the oil out the seams in the turbo.
A guy I met came by the other day and told me I had a hole in my piston. To prove it, just remove the fuel lines one at a time and see which one doesn't affect how the engine runs. Number 6 cylinder is totally dead.
After sratching my head and walking around in circles for awhile I know what I need to do. Replace the piston.
Now this is where I'm hoping for some advice and help.
Can I remove the oil pan and pull the piston out without taking off the head?
Should I replace all the pistons or is there a way to check to see if they are still good?
Do you do anything to the cylinder walls before putting in new pistons, or will they seat themselves after awhile?
Can I just replace the bearings on the crank with new ones or is there something i need to do first?
Is there a website with torque specifications for a 1989 Cummins 8.3?
What am I missing and how bad of an idea is this???
I'm realy an idiot on diesels and my experience with gas engines was 20 years ago in my youth.
Please help.
Thank you,
Eddie
