Hey guys, started up the ole 4runner and after about 5 mins of running I heard a "scratching" sound from the engine bay. Opened the hood and heard the noise coming from the distributor. Checked under the cap and I could see marks on the new cap. I tugged on the rotor back and forth and it looks like the bushings/ bearings are worn because I can get it to move. Are there rebuild kits for these or do I have to buy a whole new distributor?
