Hello Khyber lovers!
I have some query to make 
Since last 3 month I noticed my car was reducing oil , came to know that my car was having worn-out rings. A week back I noticed that the car spark plugs were also having oil. My mechanic told me that main began has some nice as well thus only replacing the rings wouldn’t fix the problem.
Small story short I have given my car for complete overhauling, what we plan to do is to install new crankshaft, instead of piston of 50 size we will install of 75 size piston and would get the head work on for rust treatment and for bore-ing at Laite Machine.
I would like to know the following
- Afterward would this require any special running?
- If yes can the running could be completed on CNG? And also if I can run my AC while running?
This overhauling is costing is around 24K including all (Parts, lait work and mechanic labour, oil and filters). Does it sound reasonable or if it’s a rip of??
Would appreciate your comments.
