2G Strange whirring/whining sound

[SameOldDSM]

Hi everyone

I have a 95 GSX 6 bolt swap which recently jumped time resulting in bent valves. I just finished fixing it and it's first start was today. She fired right up but there's a new sound coming from the timing side of the engine and I'm worried it has something to do with my oil pump but I really don't know. Also I should note, I removed everything except for the block and transmission while I was fixing the valves. I also didn't touch the oil pump or water pump since they were working completely fine prior to jumping time. I do have oil pressure, when I was spinning the oil pump to prime the engine before doing the timing belt oil came pouring out of my turbo feed line because I forgot to put it on, rookie mistake.

Everything else is working as intended after being put back together.

I should also note upon startup my alternator began smoking and getting extremely hot (it had a shower of power steering fluid when I took the lines off ). I do have a new one coming but it doesn't exactly sound like that's what the sound is.

If anyone can help point me in the right direction I would really appreciate it. The car won't be moving until I can fix whatever this terrible sound is.

That sounds like a pulley bearing dragging as it spins. Get a mechanics stethoscope and listen to each pulley while it's running.

That's a great idea, I'll do that tomorrow and update with with I find. Hoping it's the alternator and the sound is just traveling.

Sounds like the Timing cover is rubbing the belt or oil pump gear slightly. Looks like you have more than a few bolts missing. Try removing cover and see if you still have the noise. Maybe the Timing belt belt is too tight?

Just in case, first I would check the timing belt tension and if the proper oil pressure arrives at the cylinder head.

Also I do have oil pressure because when I was spinning the oil pump to prime the engine before doing the timing belt oil came pouring out of my turbo feed line because I forgot to put it on, rookie mistake.

BTW, this just means that you have oil flow. This doesn't guarantee you have the proper oil pressure.

This actually reminded me of a situation I had years ago. The nut holding my oil pump sprocket on somehow worked itself loose and disappeared (surely my error), and over a short amount of time, the sprocket wore a hole through the timing cover. Luckily my timing didn't skip, but it made horrible sounds I could never pinpoint until things failed (again my error). Would be a great spot to check for sure.

Checked my timing tension and it was a lot tighter than it should have been, the pin didn't even go into the tensioner.
I set it properly and the sound has gone away.

Thanks everyone for helping me diagnose it.
