  1. Motor: EJ 251 block, stock pistons EJ 25D heads, STI headgaskets Transmission: 5mt 4.11 ends Hey folks, I have a question about RPMs and oil pressure. I have noticed that if I am to drive with RPMs above 3k, say on the highway or if I'm accelerating aggressively often that my oil level will drop quickly. I know that I am leaking from the lower half-moons on each lower-rear corner of the heads, and the rear main is leaking as well. If I am to drive around like a grandmother, and stay under 70 mph (under 3k rpm) on the interstate, that the oil leak is very slow, and I can last a month (two fuel fill-ups) before needing to add any additional oil. Could I be at too high of oil pressure when I'm in the higher RPM ranges? If I'm running a #9 oil pump, would this have any effect? I've yet to check the PCV valve, as it's maybe three years old. I will have this motor out in about a month or two, and was going to re-seal (and mate to 5mt from '05 GT-t wagon) it, but I'd like to try and address the theory now. Are there PCVs that work better for high compression options, if this is a contributor? Any thoughts or suggestions will be appreciated. Greg
  2. Yesterday -finally- I pulled the engine on a new-to-me 2001 legacy. There are leaks everywhere -including head gaskets, apparently- but the one concerning me right now is -I believe- through the rear crank seal (see picture). I've read here -numerous times- not to touch it because of the difficulty installing the new one, but it would be ridiculous to reinstall the engine with a know leak. So... is this a rear main seal leak that needs to be adressed, or not? Also: the wrist pin cover on the left seems to be in good condition. Should I replace the o'ring preemptively? Merci beaucoup!
