Well done! Did you have the valve seats refinished when it was at the machine shop or just had the surface decked? I would think it would be a good time to put in harder seats for unleaded fuel. The '72's were still designed for leaded fuel, correct?
Thank you, I only had the machine shop to pressure test the water jackets and deck the surface. In my opinion both the valves and valve seats looked very good, but we used a little bit of fine valve grinding compound on each valve/valveseat just to be sure they are tight. I didn't want to pour more money into this head than needed, considering I will most likely change out this engine for a 3.5 later on. Even if it is a couple of years in the future before I do the swap, I don't think I will have the time to drive the car to that extent, that the valve seats will get worn out before that point.
But yes, otherwise it would have been a good to replace the valve seats, no doubt.
One of the finest I have seen, once again I am humbled by such artwork; I was thinking last night as I went through my new acquisition (88' e32) that working on these cars requires a measure of "forensics" in that each piece, scratch, etc tells a story. The time and patience put into this CSI says something about the historical value of the e9 in general, something about its re-builder and allot about the brief period in time where some cars actually seemed to have souls... and every soul is worth saving!
Thanks Robert for a great lesson.
Thank you for the very kind words Peter, and I agree that working on these cars requires a measure of forensics, and sometimes it sure feels like working on something more than "just a car". But I just want to point out that while my car sure will be a nice, solid coupe when finished, it's far from as nice as many other coupes on this forum are, my car is a total mishmash of parts from all the years they made the e9, the new paintjob sure leaves some to be desired, and I will most likely have to push forward the total restoration of the interior to a later point.
But this really doesn't bother me, while I have huge respect for those who keep everything year specific, stock and original, and doing everything to absolute perfection, that just wasn't a reasonable goal for me when I started with this project, this is after all my first restoration of any kind. Me and my father, who has helped and still is helping me alot, do this for fun and we're both just happy amateurs. So I can live with some imperfections, and I look at it from this side, now I have a very good starting point if I later on decide or want to take the car to the next level, but first I badly need to experience the car where it is supposed to be, on the road and not in thousands of pieces in the garage!
Cheers,
