longevity of 930 bottom end
HI all,
How many miles could one expect from the 930 bottom end if the car is not tracked, raced or abused? What have your experiences been with the motor bottom end? Vincent |

Thank you sir! I just finished the longevity section in Wayne's book. It looks like I'm in for many years of exhilarating fun.

my 930 has just over 160,000 miles on it and is now due for a top end rebuild only. just for ease of mind i'm taking care of bottom too even though my mechanic said it doesnt need it. If i was you i wouldnt worry till you have to take care of the top; which will usually go first...

By top end.. do you mean the heads only, or does that include the P's & C's?

Hi neighbor had his top end rebuilt for $9,000
This included everything from piston rings to valve steam seals. The P/C were in spec and reused. I do not know if this is a fair price or not but he car runs nice and zero oil leaks. Anyway his is very happy with his rebuilt motor. I still wonder if $9,000 is too much for his top-end rebuild. He laughed at me when I was rebuilding my Isuzu rodeo but the I explained I wanted motor rebuild experience of any kind to develop my skills. He was impressed with all the manuals and tools I collected over the years including a complete MAC TOOL CIS tester, valve seat grinder, and 70's Snap-On valve grinder which I refurbished to grind my own valves and seats. I explained that I was preparing to own my first used 930 and wanted to be ready to handling maintain and repair my own 930. Five years and two Isuzu rodeo rebuilds ( I have two rodeos) later I finally bought my first 930 and I so excited I cannot focus at work or sleep at night!! I just need to learn turbo charging theory and all this hype about boost. Last edited by vmisquez; 01-19-2007 at 07:26 AM.. |

It depends on the amount the car is used. I have what some call a garage queen and when I pulled the motor apart found that the lay shaft and main bearings were like new however the rod bearings had some light wear. I probably could have run it like this for a long time to come however upon inspection of the inside of the oil pump, much corrosion was evident. I talked to Bruce A. and described my findings. First thing he said was "Does this car sit lots ??"
Extended sitting time is bad for a car as well. My oil is always changed in the fall before parking it. Thanks Jerry S,
