I've tried searching breifly, but haven't readily found generic emission/pcv hose that is oil resistant. It's all heater hose. I may be not searching properly....

I'm looking for 1/2" & 5/8" ID hose. The coolant hose doesn't last too long with oil going through it.

Thanks

Bump....anyone??

summit racing has hose that is oil resistant. Check them out.

Hmmm.....I looked, but maybe I didn't look hard enough.

silicone intakes has silicone lines, unfortunately i think they're biggest is 12mm/just under 1/2"...

but, if you email them they might have something, i tried calling for my order, could never get an answer though

Ive always had braided lines made at a fitting shop we have here nearby. Ive seen the issue happen many times with our project escort. We were using summit racing's hose and sandwich adapter. The hose would get brittle as our stock valve cover hoses do. But braided lines do the trick. If these would be a part that would fit all of our cars, i may even consider doing a group by or something for braided lines.

I just went to my local "Action Auto Parts" store and they had both diameters. Its called, "emission system hose" or "smog hose". It was cheap too. Like 1.50 a foot. Guy told me it will handle oil/gas. All the other parts stores "napa/schucks/auto zone" couldn't help. You may also wanna try a diesel performance shop. Or a place that works on semi's.

Thanks for the comments guys. We don't have any action auto parts stores around here. I'll have to call around to a few auto parts stores.

Napa has it too I believe.

napa had only 1/2" And was like 3.50 a foot. Its a smaller thickness but stiffer. I didn't like it because it was hard to work with and expensive. And they dont carry 5/8 or 3/4

I should have spotted this thread sooner. Go get hydraulic hose like Weatherhead and the like. Go to diesel truck shops. They often have oil rated hoses in those sizes.
