Guys and Gals:
I have a 77 MGB Roadster. I did a complete restoration and when we started her up, ofcourse, she started first time. I have a weber on her attached pictures. Unfortunately, she is blowing blue at acceleration. Nothing at idle. Idle oil pressujre is 57 and at 2500 RPM 68-70. That being said, she has only 30 miles on the engine, 20 over, new rings, new pistons, reground crank and cam, new water pump, new plugs, new leads all new bearings, new wiring harness and complete electrical (has anyone seen the movie the Madness of King George?). Preliminary compression test gave me an average of 87 a little low I believe. On removal of plugs they are dry, a little sooty. We took her out for 15 minute spins but still on gear change a puff of smoke blue not white. The smoking has been greatly reduced from the first horrific notice, however, I am concerned it could be:
A. Rings - hopefully not
B. Valve guides - let's hope
Anyone have the answers or suggestions. The exhaust header is new and we fitted the stainless system from Moss. The pipe does look a little black now. I need someone to assist with the diagnosis if possible and ofcourse, the last thin we want is engine out.
