given the caliber of 914 stewardship here, i kind of already know...

i'm in the midst of installing a "new to me" 1.7. not intended to be the "end all, be all" powertrain, this is more of a "tide me over" until i do my long intended small block conversion. as expected, i'm doing a lot of "while i'm in there..." work.

after taking a wire wheel to my battery tray and hell hole, there's more of "less" in the former, while the later is still solid. battery tray support is also still solid. tray itself feels solid, i've been using it as a step to get in and out of the engine bay to do things like body to motor mount bar brackest, upgrade firewall shifter bushing, fuel lines (while i'm in there stuff) etc...

is replacing the battery tray an "i can't believe you haven't done this already?!", or can i put it off a few more years (until the engine upgrade) with rust treatment? the car will almost never see rain, will be driven very occasionally and lives in a garage. anybody have a battery go "walkabout" while driving due to such a tray?

if i'm convinced i should replaced the battery tray now, what's a ballpark figure for that welding job? i have a few friends that weld but, it's a bit more of a favor than i'm comfortable asking, unless my favor balance was well into the black... these particular friends have already helped me way more than i've been able to help them, my conscience dictates monetary payment.

Really nice, simple battery tray replacement. (IMG:style_emoticons/default/beerchug.gif)

I would replace the battery tray, especially while the engine is out.

If you remove rest of the old tray and pre-fit the new one -- including drilling holes for plug welds -- your friend should be able to weld in the new tray in less than half an hour.

One other option: surgically remove the old tray, leaving the inner fender wall and the support intact. Then install a new tray bolted to the fender wall and support. Others have done this before so that the tray is removable.

Be careful removing / detaching tray from the wall. You have some degradation, but it looks like its still solid enough to weld too. But be careful.

Not sure if it is just shadowing but I think I see two small black pinholes on the firewall (left side in the hell hole pocket).

Check carefully.

When pinholes start here, they allow water to enter the cabin. That in turn leads to floorpan rust inside the cabin.

If there are pinholes, I wouln't get into deep metal work at this point. Clean, neutralize with Ospho or similar, cover with seam sealer, paint to match.

thankfully superhawk, those are just shadows, it's all still solid.

thanks all for convincing me to do right by my 914. i'll order a tray and have reached out to an old friend who has a welding business to see if he is (or knows somebody) who could use a little job.

Are you sure those are shadows? Think @superhawk996 found an issue.

Like others have said, just remove the battery tray. It doesn't look like you'll need to remove the support, just the tray. But...
(IMG:style_emoticons/default/agree.gif) with Superhawk. Those aren't shadows. Have you looked at the entire firewall behind the passenger seat and the longs on this car yet?

For battery tray, I think Jeffery ( @914_7T3 ) has one for sale.

tray's been ordered from restoration designs.

i appreciate the concern about the possible pin holes. here's a better pic (sorry for the orientation). seems i missed a bit of seam sealer when having at it with my wire wheel... after i cleaned up, i realized my right angle cordless drill might have allowed me a bit more access...

at some point, i'll get to the interior and have a closer look at the firewall and floorpans. please understand, i'm a blue collar schmuck and have a limited budget and even more limited time to enjoy my 914 (not to mention several other old machines in the stable, all needing my attention...). i'm often in awe of the caliber of work many of you are able to put into you cars. my car's destined to be a "driver" while in my stewardship. i endeavor to leave someone else a good foundation when i can no longer enjoy her!

in case you are going for the 'top-tray-only' replacement, I hope you shoot some pics to show us. Good you have people around you that that can help with the welding !
Good luck with the work .

No need to apologize for being a real human, and it is your car to do with as best you can / as you see fit.

Wire brushing everything and repeated soaking with phosphoric acid won’t cost more than $20 and will help preserve that area.

My 2 cents on the rust.... Some people like the stuff, so people hate it. I have precisely followed the directions for POR15 with their Cleaner, their Metal Ready and the Paint. No issues. That stuff turns to a super hard coating. I used it on this exact same spot. Patched a VW gas tank with it and some fiberglass mat.

Looking at your pictures, I think POR was made for this exact problem.

Good Luck.

I'd love for that hell hole to have been my starting point.

Great job confirming the shadows.

You've got a great starting point that won't be too hard to fix up.

If used properly it works very well. Too many people just apply POR15 without any prep and then complain that the product doesn't work.
