i searched and got an idea but just want to make sure.. I bought a rebuilt motor and brought it to a shop to be put in..after a month they say they cant get it running. They told me it had 75 compression across, 40% leakdown in cyls 1-3 and 100% in four...yesterday i had a friend mess with the car. We tried turning it over and it was blowing air out of the intake. So from searchin i seen something about timing being off by 180 or possibly neon cams? i did notice the the the hole on the camshaft closest to me was up and the other was not? is one off by 180 or do i have neon parts in there? if i have the neons camshafts will putting the my old camshafts in a rebuilt motor hurt anything? gonna mess with it soon so any help would be appreciated.

also no valves were bent. and the rebuilt motor is all stock parts.

Put new correct camshafts and it runs fine....engine shop is getting a call tommorow

Glad we could help

Is there a certain # on the camshafts so i can tell they are neon camshafts..that way i have the power to get some money from the shop.

There's some information in there concerning the different numbers for Neons vs. Eclipse platforms for the 420a.
