Vintage, PVT & 2 Litre Forum / AC 6-cylinder engine; oil in coolant

« on: February 07, 2012, 13:01:34 »

Hi,
   I have a problem with an AC engine, which I had overhauled a couple of years ago, using a new replacement block. I have constanly oil entering into the coolant and get a smeary sludge in the radiator neck.
   However, I have absolutely no coolant in the oil; thus it is absolutely a one-way-leak; only oil into the coolant.
   I have changed the headgasket and sleeved the oil passage in the head already, but the problem did not go away.
   BTW, I had given the liners 0.010" protrusion, which shouldn't have "lifted off the head" to an extent that the oil passage is no longer sealed by the headgasket.
   ...does anybody have an idea?

Vintage, PVT & 2 Litre Forum / Ignition timing on AC- 6 cylinder engine

« on: September 03, 2007, 07:20:40 »

I am wondering, how to set the timing of my 16/80 AC 6-cylinder properly. I took one of my new blocks with bigger head-studs,  have a Phoenix crank, Carillo rods, Arias pistons with about 9:1 cr, a flow-optimised head and a post-war carburation. Compression check delivers 190 lbs. I am running it on 98 octan lead-free.
   The distributor is converted to be fully electronic; thus I can give it whatever I want as an adjustment-curve from idle to full revs. The current timing -by trail & error- ended with 10° at idle and 35° fully advanced.
   Is that correct? Any advice on the proper ignition timing?
   Gerhard
