    Engine Rebuild

    I want to lead off by reminding you that this post is not designed to attack anyone/member but simply gain advice for my issue. Any negative feedback towards them or myself will not be entertained. Three weeks ago I created my procharger build thread project for the sake of "fitting in" with the forum and pleasing certain s/c'd individuals. During this project, there were no known issues with my car other than my horn and my only past related repair were the timing guides and tensioners. So recently, I delivered my car to a member on here for the 96-98 cobra timing cover and cam over swaps. The swap took about 4 days to complete with no issues to report from my installer. My installer claimed to have went through all the proper checkup procedures before I picked the car up and even then nothing was reported. On my way home (60-70mph) from my installers home, (25 miles away) I experienced some hesitation as if I needed new plugs or cops. As I approached the upcoming traffic, the car suddenly developed a consistent hesitation and backfiring as I decreased speed. Once I've reached a point in traffic were it was stop and go, the car died on me. (embarrassing moment especially during traffic hours) so immediately I attempted to start my car but it struggled to crank over. Once it cranked over, I was lucky to pull to the shoulder of the road to search for any visible issues. There were no leaks, no smoke, and nothing looked loose under the hood. Since I was 5-10 minutes from my home at that time of need, I was blessed to limp home. Remind you, this was exactly 30minutes after I left my mechanic. Gave him a call to pinpoint an issue and unfortunately he was not able to help over the phone. I allowed the car to sit over night and scheduled a drop off time for next morning. Fast forward to his home the next morning, the car felt like it didn't want to go and it had a consistent knocking during acceleration. It felt as if the trans was slipping or I had an open exhaust. (Loss of power) Once I stopped in front of his home, the car had a faint knock, rattle noise and vibration under the hood. I left soon after that to let him diagnose the car. So days later, after the removal of the covers again, a compression test was done, oil pan was removed to inspect the crank and other procedures. His discoveries were the passenger side upper timing guide had broken off and within the oil pan, he discovered that broken timing guide and another timing guide. (replaced last may by another member) Fast toward to yesterday, I received a disturbing phone call from him saying the knocking is still there even though new guides and metal tensioners were installed. So I guess its safe to say I've recently joined the individuals who now needs an engine rebuild due to either age of my engine 127,XXX or mechanical negligence. I know its going to be hard to determine the cause of my loss but can anyone add other ways to diagnose my engine without a tear down. I have another well reputable member helping me with a marauder block but before I move forward with a replacement or rebuild, I want to use all possible options of diagnosing it.

    Thank you

    It would be impossible to diagnose what actually went wrong without having the car in front of you , guides, and chains could have been defective , installation could have been half azzed , install of the front cover shouldn't have effected the engine , but who knows what was done , or not done properly.

    When I had your engine apart, it looked neglected.
    The additional timing guide he found was the one that had broken off before you brought it to me.
    I forget, had you brought me Ford brand guides and tensioners?

    I got to see all of the pictures.
    Install looked perfect, but I suspect it was plain bad luck that caused a failure

    When we spoke, you told me that it looked good for supercharging. But maybe that was then.

    It did and it still does. On a scale of how it was maintained, I'd give it a 6 out of 10

    Could it have jumped time and bent some valves? How was the last compression test? Leak down test done?

    I have a max effort short block at the machine shop now that I have decided not to use, I'm gonna stay at 392hp vs upgrade every drive train component. I'll be selling it when it's done if you have to go that route

    This sounds very similar to when I lost my first Marauder engine. The cams seized and caused the drivers side chains to brake. Did you have an oil change before driving the car home? I will try to find the link that described the problem that I had.

    The oil was drained but added back in after the cover swaps.

    Honestly, without seeing it any decent mechanic could not give you the answers you are looking for. If you had Zack look at it / work on it I am sure he did the work correctly. Unfortunately sometimes poop happens even after every precaution has been taken. I would not skimp on your rebuild. Take your time, spend the money to do it right, do your research so that you know you are getting a quality job.
