ok let me give you guys some more details. 1986 k10 chevrolet 5.7L 4x4. I bought this truck with a blown engine, it was putting water in the oil. it had a brand new radiator & water pump on it when i bought it. replaced the engine with one i had with no problems, went ahead and used the new water pump and radiator. found that he had a bad fan clutch, replaced it. it is loosing coolant at the cap, it wont seal, used a fairly new cap that i had on hand, still leaks. it looks like the replacement radiator has a slightly larger opening where the cap seals. and everything has went to plastic tanks<sigh> is there a special cap for these aftermarket radiators? this has me stumped and i have been a mechanic for many years. nothing looks out of place except the diameter of the seal on the cap, you can see the imprint in the rubber gasket and its not covering much area to provide a good seal

magnetic material on the pickup coil, not alot but it was there,2000 ram 1500 5.2L question is what symptoms would this cause, i blowed it off with the air hose and i am gonna reinstall it, would this cause multipul missfires, and back firing?

as stated 2000 ram 1500 4x4 5.2L automatic shows misfires on all cylinders, no codes, been to two shops and scanned, last was the dodge dealer, has 120000 miles, new or rebuilt transmission, tune up as follows new cap,rotor, wires, plugs, and coil, all good name brand parts no junk, plugs are what the under hood sticker called for, new crank postion sensor,new fuel pump today, still have the problem, what can be wrong that wont set a code? no water in fuel either, please serious replies only, or if you have had this problem tell me what all you have done that has or has not fixed the problem thanks
