I'm new to the forum but have been reading it for a long time figuring out how to fix things on my 1997 RR 4.0.
Recently, it overheated and started sucking up coolant faster then I could add it. I checked the oil and it was clean of water. It started running really rough with a loss of power and check engine light.
I read the check engine light codes and it said both knock sensors and misfiring. I removed the knock sensors and they disintegrated in my hand.
I replaced the knock sensors with the newer Bosch style knock sensors with a custom fabricated bolt / connector to make them work. This remedied the knock sensor code but the engine still ran really rough and was going through coolant like crazy.
So I purchased some radiator stop leak and replaced the spark plugs / wires. As per directions for the coolant stop leak I ran the car for 15 minutes. The car still runs really rough and throws a random misfire code. It has a loss of power as well and can barely move.
There is now water in the oil, should I bother with more radiator stop leak or just bite the bullet and tear the heads off? Is the blown head gasket (I assume thats what it is) related to the engine running so horribly or is that an entirely different issue? Will bosch knock sensors not work on the 1997 4.0?
