1G W4a33 oil pump inspection...

[SasaniFab]

So after tearing the trans down and not finding a damn thing I pulled the pump apart hoping to find something.....??? I dont see shit. Seems like it has to be the converter causing the whine in drive/ reverse.

I'd be happy with it being the converter and not the pump personally so that's good ish news.

I told you in your other thread that I had the exact same thing happen to me and it was the converter. Converter will only whine in gear as that is when the input shaft is stopped and the converter housing is still spinning(attached to the engine). I would wait to hear from Sinister as that is likely the culprit.

I wouldn't be surprised if the stator broke with that noise.

I know, im just checking everything. Im installing a kiggly billet clutch pack and jeff bush transfer gears. It should be bulletproof after this.

How the hell do you break something go quick! Jesus i havent even been racing. It happened the minute the boost went up. My cars only making around 600 currently?

Manufacturing defects would be my guess. I highly doubt it was a power issue I'd say you probably just got a lame one. Just a bad luck draw.

The spragg is the weak link in the converter when you start making some good power. Another option is to go spraggless. I switched to a PI spraggless converter and its working great so far. People have said that running the spraggless will create more heat as the spragg helps push fluid through the converter. I have not had any issues with heat but I also have two transmission coolers and the larger has a fan attached to a switch. My goal is 9's and after talking with Kiggly at the shootout, he convinced me to go with the PI spraggless for my setup.

It does seem like it was defective from the beginning if this happened when you first got in to boost.

Well honestly I have been ripping it around for several weeks but all 1-3 pulls..... never launching. I think the first time
I brake boosted it it broke.

My spragg went out while just cruising so I believe it can just go out at any point whether you're brake boosting or mid pull.

I was thinking about selling it and going to a precision jeff bush unit

PI is what Kiggly stands behind and he pushes that auto to the limit every pass. He says he has been running the same converter for three years with no problems so that was good enough for me. The Sinister is a good converter, I feel it is more for cars under 500hp but thats personal opinion without any statistic backing, just personal reading and use.

There does appear to be wear on the bearing surface where the gears sit, but no it doesn’t look like it should be causing your issues.

If your refering to that small nick , it appears to be a casting flaw.

 

[CrackedDSM]

Nah. Referring to where the ball bearings are. My pump wore that down until the ball bearings looked like pac-men. Also scratched the area around it pretty good. I see some wear marks around there but again, nothing major.
