My corolla is leaking oil pretty badly from oil cooler hose closest to union pipe near oil filter. The cooler hose has braiding type section where it is clamped, with rubber covering the majority of the braiding but not where it is clamped. Is that rubber or plastic just insulation? I'll try tightening it up, but has anyone had to replace this due to leaking. It's leaking near the braiding and seems to be all frayed and shitty. Are they expensive? Would there be a non genuine part - or would I have to go to crummy toyota?
Thanks again
