Does anyone know what this hole thread is?

[GTRSOAR]

Hey everyone, im trying to find out what the thread pitch and hole diameter is of the two nipples that come up vertically off the valve cover at the back end of the engine. Its the peice where you attach hoses for an oil catch can. Im replacing the entire part but I need to know what thread pitch and hole diameter is it and I cant take mine off because the car is my DD

Thanks in advance for any help.

Ill upload some pictures after dinner

I only get to my car on weekends and next weekend I am busy. I can find out for you the week after if no one else steps up.

Don't know it off the top of my head but if you can remove it fairly easily, drive your car to lordco/napa or a specialty fastener store and remove it there and get someone to help you out, they'll know in less than a minute. Unless you wanna do it yourself, all you need is a thread pitch gauge and vernier caliper. Search up online of how to measure ISO, SAE and Pipe thread bolts its a very handy thing to know and it'll help you more than you think.

I dont think they're threaded. The RB20 valve cover vents are press fit. If you put the valve covers in the freezer over night, they should pop right out in the morning ( Shouldn't even take that long .. ).
