I decide to do a compression test since I am going through so much oil.
I warmed car up to about 1/4 on gauge would not go higher sitting on cold day. Petal to floor cranked 5-6 times. 1.Standard compression test cylinder 1 =110 PSI. 2. added a bit of oil cylinder 1 same test 150 PSI. Thats all i did. Seems like rings as was suggested earlier when discussing my oil usage earlier post.??? If rings are there any sort of cheap solutions.???. Car has 100,000 miles on it roughly. Thanks for any suggestions. Money is a issue. Although I am sure just like everything else,once you go to fix 1 problem on a 914,you always end up finding a few more. Car runs great,but using a lot of oil. Grant |

If you use a quart in 500 miles, it's time to rebuild. That's not to say it won't run OK though.

You can probably do a top end rebuild. This means sending the heads off to have them rebuilt. Honing the cylinders (if they are still serviceable) Probably new pistons. Definitely new rings. All your money will go into the heads. Its not a job you want to do at home unless you know what you are doing. Zach |
