Once it warms up the only thing you hear is the valves happily tapping away. Oil pressure looks fine. It holds nice and steady.
I haven't done a compression test on it yet. I guess in part because other than the pre-warm up knocking it runs great. Over Christmas I was hauling about 1000 lbs (if you include my wife and the fat driver LOL) down the highway with no dramas at all. I did have to drop down to second once (I'm running a 3 spd manual), but that was on a rather steep incline off a scenic route.
I guess it's just one of those things where I know the sound can't be good news. So, I figure if I can find a quality replacement engine then the old man gets to stay on the road while I work out what's going on. If I can't find one, then I'll likely have to take it to someone for a rebuild, simply because I don't want him to sit around for ages while I learn what I'm doing and track down parts etc....
I really want to learn as much as I can, but I don't want to let the old boy fo fallow while I'm doing it. I'm greedy I guess LOL
