ok so idk why but my oil metering lines seem to have melted right above the metering pump any ideas??

 

well i just put a new exhaust on and it was leaking where the headers meet the ports and i just went to fix it when i noticed the lines were melted. im thinking the exhausr heat fucked it up.

 

DO NOT use silicone for omp lines. It will swell up and cause restriction/leaking.


I have only seen melted omp lines as a result of severe overheating.


Blackrotary PLEASE STOP GIVING BAD ADVICE. YOU ARE VERY INEXPERIENCED.

 

Posts removed. blackrotary23, you REALLY need to research things before posting. Not only can silicone swell with heat, it is soft enough to tear easily. I use silicone tubing on a daily basis at work, and it is far from ideal for your OMP lines.

A rigid tubing suitable for use with oil is what's needed. We have an archived write-up thread that covers a method for rebuilding lines: https://www.rx7club.com/2nd-gen-archive-72/rebuilding-omp-oil-injection-lines-348068/
