    A few questions about a few things

    Okay, I can't seem to find any other place to post this, so any mods out there if I am in error, please move this to the appropriate forum

    Now, I am going to be coming into possession of a 1988 hearse with some issues. Quite a few are minor and I can fix myself. But, the others are outside my range of familiarity since I have worked on solely Ford vehicles. I have been told this car had an idiotic previous owner that had, at some point, put the wrong antifreeze into the reservoir. How much, I don't know. But apparently it was enough to cause some issues and has gummed up the works a bit. Any suggestions as to how I can clean this out? It also has a crack either on the block or head my friend is unsure of which. He discovered this when he found where it had been JB welded shut and the repair had failed. He says he appoxied it again and it does okay, but it still has some problems retaining water. How would I check to see if it really is the head (I do believe that's what he has said)? And if it is that, can it be replaced?

    Those are the only two major issues I can remember off the top of my head. Everything else is tune up, pinhole leak in either the radiator or a hose, brakes and tires. Stuff I can do, lol. Any suggestions? And if further details are needed, I will find them out and post as I am able.

    Can you post pictures?
    Of both your car out of interest and of the engine crack for evaluation.

    I would if I had access to it. My friend lives 45 minutes from me. I plan on going to look at the car this weekend and test driving it. I ask the questions now so I can be prepared for the repairs in the future. Make sense? I can probably pull a pic from my ex's Facebook page. It was his before my friend bought it from said ex's ex wife (she didn't want him to have it type of deal).

    Re: A few questions about a few things

    Ok, so this is what it looked like 10 years ago?
    I am not an expert on engines, but as an engineer I would expect that when the block has a crack you need to weld it inside and out. Epoxy will not hold long. I also expect a crack to result from heavy load. That would be more like the head than the block. But also an exhaust header is prone to cracking (even more than the head). I hope for you it is the header and not the head (although you mentioned about retaining water, so it is probably the head anyway).
    On the other hand the 4.5L is not a rare engine to find parts for or a replacement. At least a lot more reliable than the 4.1L

    I don't have any recent photos. But, it still looks this way from what I have been told. As I have stated, I don't own it yet. I'm waiting on the money for it. I'm just trying to get as much information as possible so I can be prepared for fixing it up and getting it to run correctly. I'm going to be headed to my friend's house this weekend to give it a good once over, take photos, and possibly test drive it.

    Make sure you check the engine before and after the test drive
