HSR oil baffle

I've added an oil baffle to the bottom side of my HSR intake and I'm not to sure that I trust this hardware. Drilled and taped 10-32 into the 4 bosses on the under side of the intake. The holes are approx. 1/4" to 3/16" deep. My question is would you trust lock washers and Loctite to keep the screws from backing out? Other than welding the baffle in place would you suggest any other form of hardware to mount this?

Yikes. If those come loose you're going to have three pieces of debris per fastener blowing around inside your engine.

Auto manufacturers use drive rivets to anchor various shields inside engines. I'd look into that as a tried and true solution.

Screws are probably fine, but I don't think I'd trust Walmart hardware aisle spec stove bolts. Personally I'd look into a screw you can actually torque, either a hex head, socket head, Torx, etc. I'd definitely skip the washers and lock washers, opting instead for the most permanent thread lock I could find. Might even consider staking the hardware, or fabricating a sheet metal locking tab to keep the hardware from backing out.

Re: HSR oil baffle

If I was going to do that I would ditch the flat heads for something hex then I would use red loctite and nothing weaker. After red loctite you will need hex heads to remove them because that **** is so strong. I might also consider safety wiring them in after.

Another idea would be to put studs in with red locite then you can use lock nuts and stake and loctite them so they don't move.

Re: HSR oil baffle

First off make sure that big flat plate isnt gonna resonate and tear itself up.

i would then weld it (assuming it's aluminum) to the intake.

if you must bolt I would recommend safety wire

How would check to see if the baffle won't resonate?

Can you bolt it in the middle anywhere?

I'll take a look at it after I get it back from our machinist.
