BAD NEWS: I was getting Black Beauty, Jensen Healey #13046 prepped and ready for my first foreiy into SOLO II. I was out at The Streets of Willow shaking her down and was running very well on an Open Track Event and giving a few Miatas a rear view of the Jensen Healey when something broke.
I'm still trying to figure out exactly what it was/is that happened. Smoke started billowing out he tail pipe and looked like oil smoke but it just didn't have an oil smell, or water or anti-freeze or... I pulled the plugs and the plugs had oil on them and the top of the pistons were a wash with oil, especially #3 & #4 cylinders. I used a lighted bore scope and there was no doubt of the oil. I suspect hydro locking, but I need to know more.
I put her back on the trailer and took he to the shop where my mechanic did a leak down test which was pretty good and yet I had lost serious oil pressure at idle, so it looks like a total rebuild at this point, I know I didn't over rev her, (6K RPM's Max) but something happened. I now have three (not running) 907 engines so, it looks like I'm going to get a chance to rebuild the engine to a 2.2 configuration, wheather I like it or not.
If you have any idea what may have happened in the above failure mode, please let me know. Buy the way the engine continues to run fine (Just smokes like it on fire!) and above 1,000 RPM's I have normal 50+ PSI oil pressure. It doesn't seem to be valve guides, though that was my first thought as that is a known failure mode.
Any ideas and assistance would be appreciated. Thanks.
