I am rebuilding my engine, and was just wondering what is recommended to replace. I have ran into the ever popular "lack of funds" problem but would like to have a working engine again for as little as possible, if you would be so kind to help out it would be greatly appericated

 

First you have to take it apart to see what you need. If you luck only as gasket kit, oil seals and front/rear seals

 

Well... obviously you shouldreplace all the soft seals... but you really should replace the rotor and stationary gear bearings, especially on a high mileage rebuild.

Lots of guys re-use the roto oil seal hard rings cause they are *** crack expensive.

Honestly... the only time i would re-use anything is if the motor had less than 50K on it and your re-building cause of a coolant seal or something. It takes so goddam long to spec everything out....

Remeber.. if you re-use the hard seals.. the gotta go back EXACTLY where they came from.. If you've even done a side seal kit, you know why.. you have to custom fit each one as you put the new ones in!!

 

I heard rotor and stationary gear bearings are made to go near 300K if kept in good condition?

Anyways, I think it will be fine as long as there isn't too much copper showing.

 

If you have an S5 engine the likelyhood that you can reuse the parts Decay is talking about is a lot better... mine had 158k miles on it... and everything is re-useable, everything is at the highest factor specs too. The previous owners apparently didn't drive the car hard... ever. Which was nice for the parts, but crappy for when I had to clean the 1-2mm of carbon caked on the rotors (seriously).
