Re: 1978 Bayliner Quartermaster restoration
Just a little update. Well the first run ended with the dreded oil milk shake. Went out the next morning and pulled the dip stick after repairing the water leaks, and :facepalm:. So in my search I started by rechecking the head bolts and found #2 to be almost a turn out from torque. So I pulled the head after seeing a tatle tail sign that a small amount of leakage to the outside had occured. Yes I cleaned all the threads and torqued the bolts in sequence. When it comes to critical torques I'm a little fanatical to say the least. So much so that after reaching final torque I went through them 3 times just to make sure. So any how I changed the head gasket cleaning all the bolt threads again and checking each bolt for stretch. All good. Only thing I can figure is there must of been somthing on the thread.
So installed new plug wires hooked up the timing light and went for it again. Set the timing. Adjusted the idle. Noticed that it was running a little hot (180) so I pulled the thermostat. Which I bought new. Ran the engine again without it. Beautiful (160). So will replace the bad new thermostat. Decided now with it running at a normal temp range to run it a little checking the dip stick and pulling the oil fill cap. Just as I start feeling up. The dreaded froth appeared in the back of the oil fill cap. Sure enough watching the oil on the rocker it was starting to turn. A check of the head bolts only proved all to be tight still. Now I'm scratching my head. Did the machine shop miss something?
So I decieded to pull the oil cooler. Emptied the milk shake out of it and cleaned it up. Decided to run water through it as if it were on the motor.So I clamped a modified garden hose onto the inlet and let it run for about 5 to 10 minutes. Disconected the hose and tipped it on its side. sure enough there was water in the oil side. Did it one more time with the same result. Sothis morning I pulled the core and pressurized it without the housing. Sure enough we had bubbles. I then went through and started pressuring individual tubes. I found the center tube to be the culprit. So now to find a radiator shop that can repair it. And sorry for the length of this.
