I recently rebuilt my engine because i blew a head gasket and so i replaced my head gasket and piston rings because they were burning oil..

Now i have maybe put about a 1/2 hour of running time on my motor and did a compression check and im getting 160 across the is this because my rings havent seated yet or is there something else wrong i had a leak down test done to my head and it was said to be normal..

Any suggestions..

 

BUMP>>someone has to know something

 

Since you are getting 160 across the board, I would not worry about it. Your compression will increase once your rings have properly seated.

 

At this stage, its more important that all cylinders are even. Your rings aren't broken in yet so the numbers will go up.

 

Did you test with a cold or hot motor? Did you fully open the throttle? Sometimes when you don't fully open the throttle you will get lower numbers.

 

Thats what i was thinking but the motor was hot but now i think i didnt have my foot holding down the gas pedal but i took the ecu fuse out under the hood..So i am going to try it again with my foot down on the gas and then hopfully when it broken in ill get better #'s..

Thanks guys for the posts..

 

Yeah--alot of times people post low but consistent numbers and they didn't open the throttle all the way. It does lower it on a plenum manifold but on ITBs or sidedraft carbs it cuts it in half. I forgot to open throttle on my carbs when doing a test once and I think I got around 120--fully open 255-260.
