I know my motor has a lot of miles on it. The guy I bought my donor car from said the odo had just stopped at 187k when he bought the car 6 years prior. He also said he 1/4 miled it regularly and put at least 100k more miles on the car in those 6 years. Even thought the dealer he bought the car from said it received a rebuild on the engine, when I freshened up the motor with new gaskets and put the intake on I could tell that motor had never been taken apart in it's life!
The engine ran pretty good since the conversion up until about a week ago. Over the past week it's feeling "lose" for lack of a better term. I can feel more vibrations and hear more tapping going on. And I think I hear a little bottom end knock when I first start the car in the morning as well.
So I think what I'm going to do is use this lower mileage explorer short block I have, throw a set of GT40 heads on it and maybe a cam and put it in my car. I was hoping this motor would last until I had a 351 built for it but it's looking like that won't be the case.
I went on a short road trip yesterday and ran the motor at highway speeds a lot. It already felt out of sorts then, but this morning when I fired it up to go run some errands it was making some wierd noise I can only hear from the inside. Noise sounds kinda like water trickling or being forced through a small opening. It sounds like it's coming from the bellhousing area and doesn't change with the clutch in or out. Can anyone tell me what a bad crank bearing would sound like?
