It appears that the search is slightly broken at the moment...

OK, long story short. Porting an S5 TII intermediate plate, and I was a little too aggressive with the bottom half of the port. Right into the water jacket. Since the plate is in relativly decent shape, and considering the rarity of the S5 TII engine parts, my first thought was to weld up the hole...

A short conversation with what I would consider a pretty experienced and knowledgable welder took place, but I was disappointed to find out that he thinks that the localised heat would cause too much warpage. But I know that I've heard of people welding up housings before...

Any thoughts from anyone in a similar situation? JB (DC ) weld is not an option.

 

what about devcon?

 

yep weld it up.
use a arc welder, there are special rods for doing cast
that will weld it up nicely, the trick is to do very small
shots of weld at a time. when you first start you will fill
your pants because the hole will get much larger, but
using very short bursts of weld cleaning the area with a
die grinder before starting to weld each time you will
slowly fill the hole. its done lots on heads.
bad news is the rods are really expensive!
i paid almost 100 dollars for a pack of 12 i think it was

also you want to cool the area with a damp cloth each
time to keep the heat to a min.

Jb weld ive heard works well too. And if your worried about warping (i dont weld but this is from seeing posts on the subject) preheat the housing.

 

JB Weld is crap. Never use it.
Devcon is the best steel hardener mix.

 

I say use, JB. I wouldent try and weld it, trying to weld it is a waste of time and you will more than likely warp it. I would clean it thourougly and then rough it all up, then clean with alcohol. then apply JB. I have used jb on making PP housings and never failed, plus its easy to obtain at your local hardware store. Fill it up good then grind it down to the contour of the port. congratualations, you now have made your first epoxy port.

Why would you want to use JB? That's crap compared to Devcon.

 

JB weld isnt crap, ive had great results with it, ive had pineapple style sleeves constructed of jb weld in my intake for more then a year now, no problems. Many people prefer JB weld to devcon, but its your choice.

 

I've seen too many people post up on how they used JB weld to do something in there intake then a few months later come back to say there engine sucked up a chunk of jb weld and now they are replacing it!, so I vote nay on using JB weld for anything intake related!.. lol

 

I would never use JB Weld for something so critical...But if welding has been done in the past with success, then it might be an option...

BTW, I did use JB Weld in some "test" PP housings I made, but was not impressed...Devcon is much better as already mentioned.

 

Haha, I just read your Avatar text. Maybe we can throw In a bolt In there...It's becoming standard with some people who port to far (I'm not kidding).

No worries, a mint one Is on the way.

 

Haha, silverrotor with the sly reference to the drama in the Canadian forum at the present time.
