I bought a can of seafoam today,and I want to put it in the gas and run some thru the brake booster line too.I was wondering if it is recommended to run it into the brake booster line on a corolla.I'm not putting it in the oil because it may actually clean evrything in the oiling system,like seals, too good and cause them to leak.I've heard that in high milage cars,the crap in the oiling system actually keeps the old dried out seals from leaking.Once all that crud is out,they start leaking
