Valve Cover baffle holes

[LidnDom]

I cut holes into my valve cover so I can weld AN fittings on them. During the process I drilled through the baffle. Is it safe to run the car like this or should I plug the holes?

You should remove the baffles and replace bro. There's probably tons of metal under it and will contaminate and ruin your turbo/engine! Theres no way you can be sure you get it all and that's a huge risk to take bro. There's a member on here that sells replacements, check the freelance page.

He's absolutely right. Clean it super good and get another baffle and weld it in. Since someone is going to have to weld the an bungs. Don't risk those metal shavings

I personally agree with the other two posts, no sense in taking a chance ruining a motor with metal shavings. You can weld repair the holes if you don't want to buy a new baffle. I wouldn't run for long with the holes open, as oil will be splashed up and you will get oil in your vent return system.

I believe the stock baffels are magnesium so they dont weld too well... Thats why @greengoblin makes aluminum baffles

OEM baffles are steel.

Not a bad idea to order a custom new baffle from green goblin they are awesome, you should realistically pull the stock one off so you can better clean the under side of the valve cover, a lot of sludge can get trapped on the upper side of the baffles.

Since you will need a replacement baffle Goblin's would be a good choice but if you ever do it again you can remove your stock baffle and reinstall it. Here's a write up I did. http://www.dsmtuners.com/threads/removal-and-reinstallation-of-valve-cover-baffle.427887/

Right, even more of a reason, they won't weld in.
