No start after rebuild. PLEASE HELP!!!
Sorry for the long post but Ive been on the search for 2 days now and Im at whits end.
Okay so I rebuilt my engine over the past couple weeks. Its an 88 NA engine with 200K on it. It ran perfectly fine before I pulled it. The reason for the rebuild was bad oil control rings making it lay down batman style smoke screens. The rebuild went smoothly no problems what so ever. I used Atkins rebuild kit and replaced all the soft seals, springs and apex seals. I had to reuse the housings and irons for financial reasons but was told that they were in pretty decent shape for a car that had that mileage. Still plenty of chrome and no step wear on the irons (verified with a dial indicator).
So I get done, fill it with fluids, check over everything a second and third time and crank if over for the first time. It started right up to my surprise. Idled high and dropped down like its supposed to. It ran perfectly fine, beautifully smooth for about a minute or so then the idle started to get rough like it was missing slightly, then worse and worse and it finally died. Tried to turn it over again and it would fire. Just cranked and acted like it was truing to fire but no dice. Tried to deflood and a little atf in the leading holes. Nothing but fog from the exhaust. I can get it to fire if I roll start it and pop it in second but it will only stay running if I keep my foot on the gas. It will not hold an idle at all. Ive tried readjusting the timing several times, took the intake off to check the vacuum lines and primaries but theyre all good. I took the plugs out to listen for whooshes and I get three pulses from each rotor. Compression tester shows three even pressures of around 80 on the rear rotor. The front shows one pulse of 80ish and two lower around 50 but even with those numbers I should be getting something right? Ive read that a fresh rebuild isnt going to have great compression right away until the seals seat properly. But Ive seen engines run on one rotor alone so surely the weak comp in the front wouldnt keep it from running at all. :banghead:
