Just like it says. I am doing a rebuild on a N/A 13B. The front Iron has that real thin spot down by the exhaust port. I think Its .061" thick. Bruce T said that people put Epoxy in that spot to beef it up. Have you done this?? Why is it good? Why is it Bad???

I

 

I haven't done it.. but that spot is the reason my engine crapped out on me... ithe whole wall in that area "Disappeared" into the coolant system leaving the compustion seal to its own devices.... the car never smoked, it just wouldn't start one day like it was flooded... had to keep changine the plugs everytime I shut the car off. The new iron i got was pretty thick there, so i didn't bother with the epoxy

 

Did it. Sort of. This was on an S4 TII. JB Weld w/ a peice of side seal and apex for brace. Motor popped from running lean about 3K miles later. Repair job was still holding together.

 

have done it and will continue to do it, there is no drawbacks to doing it aside from the piece possibly coming off and plugging up a coolant tube which shouldn't cause a total catastrophe.

the bridge is not always thin in the same spot in all castings and can fail anywhere that the casting is thin, the machining process can yield perfect housings or thin walls in any spot on the casting depending on how the cast was made and how the piece was chucked to the mill. adding epoxy or JB weld will protect that area from failing but i would not suggest doing what the above poster did, i have tried some rig jobs like this but it is for a temporary repair not something you can expect to last a decent amount of time.

 

I don't want to do what Wizz did. I am going to use the good front iron. I think that area should be beefed up BEFORE it breaks.

I spent all night masking and painting the three irons. They look good. I post pictures when I get some rest.

 

Honestly, I won't do what I did. But sometimes you're in a pinch and you gotta do what you gotta do.

 

I heard that!! You don't always have a spare grand or so hangin' around.
