First time posting on here.

Picked up an 01 civic as a dailey driver, got it with 72000KMS and its been a headache ever since. I've had it in the shop 3 times in about 3 months. It seems the crank seal keeps blowing out or getting wrecked causeing the car to leak oil. What could cause this? Makes no sence why the seal should be blowing out I dont drive the car hard I just use it to bomb around town. This is my first honda and its very frusterating. Thanks!!

Car is a 2001 civic 1.7 5spd

Sounds like it's building up too much pressure and blowing the seal. Previous owner may not have changed the oil enough. If you don't change the oil the oil galleries in the engine get clogged and build up pressure till you blow a seal. Pull the engine and clean all the oil galleries. Have fun.

Ya i'm pretty sure the previous owner rarely changed the oil based on that i've seen. Is there anyway to clean out the oil gallies without pulling the motor? I dont know the first thing about these cars i've only ever owned and worked on v8's before. I was thinking maybe putting sea foam or an oil additive in the oil to clean everything out? Thanks for the reply!!

I asked a couple of guys about this and only 1 said he had it happen and he said he suspected it was one of the galleries in the head and just poked it with a paperclip. lol. I have a buddy in auto tech class, I'll see if he can ask at school tomorrow-stay tuned.

Ok, buddy was still at school, he said to go down to the autoparts store and get engine flush. If that doesn't work he said to check for a clogged oil filter.* It's actually pretty easy to check as the oilpan unbolts and drops thru the sub-frame.
