Hello, my name is***** will assist you.
What engine are you working on?
Thanks, ***** ***** have the full model number from it?
Let me see what I can locate with that.
Ok, have you checked for spark using a timing light when the engine is misfiring?
How hot and for how long was the engine?
When was the last time that it ran correctly?
Ok, before we get too far into this, you are going to need to do a compression test to make sure that the block is still ok.
The engine would not really need to be making any odd noises to have a bad cylinder. You are also going to need to pace it under a load, on the trailer, backed into the water and placed in gear, and bring the RPM up to where it begins to break down, then use a timing light to make sure that you are still getting fore to all 6.
Yes, you can reply back here. There are no time limits here.
