Hi guys, anyone familiar with this issue?
I have a rebuilt 273 small block on a '66 early A with an original 3 core radiator. I noticed the engine running slightly on the hot side, and a spray of coolant was left on all over the engine followed by a small puddle of coolant dropping from the bottom of the engine. I flushed out the radiator, and added new 50/50 coolant in case it was clogged with too much stop leak.
While flushing the cooling system, the timing cover gasket busted at the top corner, causing antifreeze to spew out everywhere (hence the spraying.) I added new coolant and had the cover+timing chain/gears replaced, and sealed up. The coolant started to get cloudy right before the cover seal repair and again right after (by now there is all new coolant.)
A few weeks of driving around town, the engine runs better than ever, not overheating, oil is perfectly clean, but coolant is still cloudy. I know it may be easy to say it's a head gasket problem, but before we get into that, I would like to know some thoughts. Much appreciated!
Note: Months prior to this issue I had a brand new 4 core copper radiator installed, but one day it busted a large seam at the top edge opposite side of the hose. No warning or overheating. 3" busted seam. Nice radiator, but chances are it was a faulty one. Still suspicious however...
