1G Oil Pump Problem

[AlexJ]

Hi All - Might be a newbie question, but I searched all over the forums and couldn't find my exact problem.

History: Bought a 1991 talon TSi AWD with a blown rod/hole in the block, and then found a professionally rebuilt/decked block and head. Moved over the ignition and exhaust and dropped it in.

Problem: After putting it all together I found my oil pump sprocket will only turn Counter Clockwise and feels a little "catchy". Trying to turn it Clockwise it locks as though it is clutched. Newbie error I tried to fire it up anyway (after not finding any posts) thinking it would work itself loose or perhaps something else internally would release the "lock". All that happened was a terrible sound from the crank chewing the timing belt as the belt itself was seized by the OP sprocket. Luckily the belt never moved, so the cams never moved from the timing marks and after examining with a camera, no damage to piston heads or valves.

Question: I'm wondering if the "pro's" put in the pump incorrectly, or used a the wrong one? I think EVO's mount opposite from the way Eclipses do it - (not sure if they they spin CCW as well?) - so could they have have installed the wrong one? Anyone ever have this particular problem?

Thanks!

Did they use a new pump? If so either got a bad pump or maybe they didn't line up the marks up on the oil pump gears correctly. There are dots on them that must be aligned.

Dots wont matter for this problem. That just affects the balance shaft phase. You have to take it apart. If this is a zero mile motor somebody screwed up.

If they did a BSE, they forgot to put the dummy shaft in. Will bind the gears real easy. I would be concerned.

It sounds like there is a ton of play somewhere in that pumps gears, or just the opposite.

This. If the shaft is missing it will bind against the housing in one direction. Someone definitely messed up and didn't install something correctly, which may be saying something about the rest of the engine...

At a bare minimum the front case must come off.
