Pics of my oil pump gear caught fire coming loose and catching timing belt cover fire

[95EclipseGST]

I had my oil pump front cover and gears sieze up or the bolt came off and i used red thread locker an torqued to proper spec. It obviosly came loose, so how much further past 30 ft lbs should i torque it to? I dont want this happening again. It made my timing jump teeth and caught my timing belt cover on fire. I dont understand yet how i sprayed oil all over my drivers wheel well, but heres some pics. The gear that i have is bent and now i was wondering if it was ok to use this topline gear to replace it, or is this something that should be OEM. Topline gear is pictures in first pic. I even want to get a part number for the bolt that holds it on, to do everything right "again". In the last 2 pics, you can see the bolt is still attached, so i dont know waht could have caused this, thus making me nervous to put it back together and try it again. I bought a whole new oil pump front cover, and oil pump gears. Anyone know what could have went wrong? I cycled the oil pump to where oil was coming up to the heads and everything. I lost oil pressure all the sudden and shut off the car. I dont get to work on it again till after christmas, but if anyone has any idea or has seen this happen before, let me know. Is it highly likely that i spun a rod bearing after losing oil pressure or messed up my shortblock? I probably have bent valves cause it jumped timing, but do you think the block is ok?

Wow that is quite the mess. The proper torque on a fastener will stress the bolt to stretch a bit, this keeps it tight. If 30lbs is what will do that, the 271/272 locktites should not even be needed. What's more only a couple of drops is all that is needed. I would check the fit on the gear to shaft. It is criticle to give the bolt a fair chance. I would too use the locktite again. Clean everything with brake clean before assembly. The pump seal should be replaced without a doubt also. The gates racing blue belts 167rb are about $125 now. It is the same kevlar belt sold by hks, tomei, etc for twice the money as Gates is the only manufacturer of a kevlar belt for our 4g63s. You might not have bent the valves. It will run a tooth off. Tres..

I had a Topline oil pump cover "NEW". That the stock oil pump drive gear would rub. Was the oil pump cover from topline?

You mean replace the pump seal as in this one?EXTREME PSI : Your #1 Source for In Stock Performance Parts - OEM Oil Pump Front Cover Gasket : Mitsubishi Eclipse 6 Bolt

No it was an oem front cover and pump with oem gears. The topline gear is something i has laying around. What is a part number for the oem gear in that first pic for a 6 bolt and the nut that goes with it? Are you saying that my oem gear will rub? or the topline when all put together?

The oil pump gear (oem) would rub on the Topline oil pump cover about just were the teeth of the gear is. It put a hole in it oil everywhere!. but Go over everything when your done send it see if it binds up of scratch the cover. You can have play in the oil pump gear set. too?

Im not using a topline, although i have one. I was just going to use that gear that came with it. Im looking for an OEM one right now but cant find an online vendor or part number for it. Whats that gear in the first picture even called?

I had this exact same thing happen to me with a pump cover from ROC. I had to take a drimel and take a little bit off from the outside of the cover where the gear was rubbing.
