Inside engine pen markers

indr · 02-08-2013, 12:37 PM

What is the name of the special markers/pens used to mark bolts and other things inside the engine to see if they have moved due to vibration? Special ink/paint is used since it is very oil resistant...

I think they are just regular paint pens.

Also found this.

I've used a regular ol' paint pen many times, and the marks are always still there next time around.

Nail polish is also incredibly durable. And it comes in all sorts of nifty colors. Check the sale bins in the drugstore next time you're bored.

Like any other paint, surface prep is critical. That said, nail polish works great and will last near forever in the motor.

torque seal ?
Not really a paint but it's used to show if a fastener has loosened.

I'm wondering if it's really a good idea to use this inside an engine -- it's basically designed to flake off easily if there's any movement between the fasteners at all. The flakes probably wouldn't hurt anything before they end up in a strainer or a filter, but...

I have some torque-seal in a few different colors, but I only use it on stuff outside of the engine. Also, it's sort of pointless to use the stuff in a place that's not easy to see.

Scratch marks with my trusty old awl. I use them before so I can realign things I don't want to change. I always find them later, well in line with each other.

Works well on the road if just to retorque things at close to the previously set torque.No need to carry a torque wrench...altough some seem to want to do that from another thread.

Dismantling a lot of similar parts, punch marks just like grandpa and probably with his center punch, I'll look next time probably has "his" mark on it. 1 to 1....2 to 2 and on and on.You can sort of code them if you don't want to do like 8 to 8. Sure saves lining up the parts on the bench and cleaning one by one so you don't mix them.

Probably even in my pretty old mechanic's books that, the punching marks.
