Couple V6 questions

1. Just discovered that my oil pan has worn a hole in on the bottom corner. Is that something that could be cleaned up and JB welded from the inside? Not sure if JB weld would stay on permanently when subject to oil? Other advice?

2. I've noticed fuel starvation ever since I put on a 2nd fuel filter. Is that to be expected? Initially I had just one clear filter in between the pump & carb, and I recently installed a 2nd one in between the tank & pump. Now I only notice occasional splooshes of gas in the clear filter next to the carb at any rpm, and it's almost always bone-dry looking. Just wondering if that's expected. Maybe the filters slow the flow enough to notice symptoms like that?

Thanks!

 

You know about the screen/filter in the gas tank right? Maybe its clogged? Mine has a drain plug. I ran it low once, drained everything out and flushed it before refilling.
Maybe fuel pump? try splicing a tube upstream of the clear filter and see if it fills better.
As to the oil pan, I have never had good luck with JB on something that gets hot. Why not have it brazed? Bernzomatic makes small welding rods you can use with a can of Mapp gas. Dont know, just kicking out ideas.

 

And good ideas they are, thanks Maxx!

For fun today I replaced the fuel inlet hose with one that went directly into a red gas can and ran it. The filter did pump out regular spurts of gas and it had a steady amt. in it at all times.
For fun, I replaced the tank-to-pump filter w/ a clear one, and replaced the lines incase something built up. In the process gas streamed out of the tank outlet, so I know that's not clogged.

Oil pan brazed...sounds like a good idea. Radiator shops do that, right?

 

could it be that the pump is trying to suck thrugh the first filter and pull through the second??

 

never had good luck running 2 filters, only filter AFTER pump.

 

I have a filter on each tank, between tank and changeover valve
I then have another between pump and carb
never had a lick of trouble; using stock mechanical pump

 

Worn oil pan or rust?

If rust, an area the size of a quarter may be soft and it won't braze well. I hope I am wrong but you need to take it off and clean 'er up to see.

I just saw on ebaY yesterday a guy selling 14 bolt chrome Bu-ha (Buick) V6 pans for $35 ($38 BIN --$11 ship. It say 75-83 but I thought 14 bolt was all the way back to inception of the V6. 1984 went to 20 bolt. Maybe someone else can confirm.

BLING BLING BABY!




Hey -- I think jpflat2a just clicked "buy it now" R)

 

Hmmm, that's what I'm trying to do Jim. Can't imagine why I'm having trouble. Although I just realized, as someone else pointed out that there is a filter over the pick-up tube in the underseat tank, so I prolly don't need one in between the tank & pump.

I was just wondering if the flow of gas is significantly reduced with the addition of another filter. Should it matter, or is a reduced flow what I'd expect?

 

Dang, I hope it's not rust. I had much of the weight of the engine sitting on the pan alot lately, especially as I was bangin' it in & out of the engine bay all summer. No dents, but there does appear to be some pitting on the outside. Haven't dropped it yet to check.

Anybody else think an oil pan is/isn't JB weldable?

Thanks for the replies guys!

 

doesn't appear to, but I'm not an engineer!
my outlets are on the bottom of each tank, gravity assist so to speak
if the filters are new and/or not plugged up, and your pick-up sock is okay, I don't think it would be a problem

 

Thanks, that's sorta what I thought.

I'm going to try and remove a filter and see what happens. Thanks all.

 

Alan: You shouldn't "need" a filter from the tank to the pump. Unless, you know that there is a lot of crud in the tank, then that filter would plug up pretty quick. If that's the case, it's better to flush out the tank well and be done with it. Usually, you can check a filter by shaking the gas out of it and blowing thry the inlet--there shouldn't be much resistence.

On the oil pan, I think I would have it brazed. If no rust, not a big deal.

But, that chrome one does look nice, No?

 

Alan if you know someone who is good at TIG welding they can fill it in also.
Your knuckle will be in the mail tomorrow am.

 

I wouldn't use JB Weld on a oil pan either (unless I were stranded somewhere).

 

On a rental Omni (best off-road car is always a rental ) I used some epoxy putty from a FLAPS to repair a hole in a oil pan.

 

Thanks guys. My buddy said to stick a sheet-metal screw in there (w/ gasket) and that'll stop the leak. R)

It's coming off tonight and I'll be able to evaluate. Mike thanks for fixin' the knuckle!

 

Dang, looks like I have some rust problems with the oil pan. Not sure it's salvageable. I've got a welder-buddy who has offered to try and braze it.

 

I've had my eye on a chrome pan for a while. I questioned that guy last week, and he says that it'll fit the 225. One of these days soon, I'll get mine off of the pallet and onto the engine stand, and spring for one, and see if it does fit. Hippo, if it works out, I'll have no use for my original pan...

 

Thanks jim for the generous offer.

I'll keep everyone updated, as I plan on taking the pan to my automotive guru this weekend. Oh, I'm skeptical that the chrome replacement pan will work. Not sure why I'm skeptical, but I'd sure like to see some side-by-side pics for fit and depth.
