Hole in block.

[merleti]

I bought a G14 on Monday brought it home and cleaned it up. I noticed it previously had a hole in it were someone patched it. It looks like they patched it with JB Weld and did a decent job. It dosen't leak, but I'm not sure how long it will last. Any thoughts on how long a fix like this will last?

I'd bet the repair will last between.....1 day and 30 years. That JBWeld is good stuff, provided they cleaned it and used it properly. If it's anywhere near a "stress point" it won't last long, but if it's "just a hole" then it might last forever. I've seen that stuff do some amazing things. It was originally developed it for just that purpose, to fix a hole in an engine block, by a guy in a machine shop.

As long as its in a flat area,not near a structural part of the block(cam journal,crank bore,etc..),and you dont see any hairline cracks anywhere, it should be perfectly fine.Seen it done plenty of times,done it before as well when the block couldnt be welded(some mfg use poor quality alum,and it cant be welded properly).Hope this helps.

Thanks guys. I would have put a pic on but my wife took the phone charger. The hole is behind the cylinder just past the vacuum tube, and has no stress points. I do feel better thank you again.

I think the bigger question I would have is how did the hole get there? Was it a result of a thrown connecting rod or something else? If a rod was thrown, did the previous owner simply replace the rod and patch the hole, or did they do the proper thing and check for (and replace or renew) scoring on the cylinder walls and crankshaft bearing surface? If it was a simple "replace-the rod" repair, you could be looking at another failure in the not too distant future.

Something to think about.

I've patched a few small engine cases with thrown rods using JB weld or Marine Tex, if you clean/prep it holds fine.

Marine Tex is the bomb, makes JB Weld look rookie.

SandbaggerYDRA I just purchased the cart, so I cannot comment other than the owner said the top end was rebuilt.

The first pic is a top down view. The second is the back side. As you can see there is some oil seeping through after 3 hrs of use.

Yes the pic at the end does say coors light fixed it. I pressed on it and it feels like a few layers were used.
