Looking for guidance!
(AH 3000 MkIII)
I just completed a head rebuild. I'm concerned though because on my first ride (40 minutes or so) the car is blowing huge HUGE amounts of smoke. I believe it is primarily blue smoke (mostly). It does not appear to smoke when coasting, but smokes some when idling and then smokes a lot when accelerating and driving. And it keeps smokin'. The car did not smoke or smoke very little before the cyl head rebuild.
I have read in other posts that smoke is normal at first during the break in, but I assume that's mostly with complete engine rebuilds.
Oil pressure is fine. The car runs smoothly, but after 40 mins I could tell the plugs were getting a little dirty. The breather tube is clean and clear. I will test compression this week (need to get a tester) but I know from earlier testing that compression was very consistent across the cylinders before I pulled the head.
I feel that I adjusted the valves too tightly at .012 cold for this first run and need to correct that, but would this contribute to oil burn?
My rockers were re-bushed and the shaft had no visible wear problems, but my primary suspicion is that there is too much oil spraying around the top of the head. Anyone have experience with a problem in this area?
I'm anxious to rule out any major problems, like rings. How should I go about tracking down this problem?
