I am putting a filter relocator, thermostat and cooler on my setup, the problem is the tube on the back of the motor is too long and I canty get housing to seat on the back of the block, I taped up the threads to keep from damaging them, but they got screwed up any way so I just clamped on vice grips and figured Ill get a new one and have it machined, but I still can t get it off... is it a reversr thread? or do I just need more brut force and ignorance!!!! any sugestions???
