Water/steam coming from exhaust

Hi,

Well, I decided to pick up an 87 Samari due to it's ability to get into some tough places that my old '70 Blazer doesn't like. Problem being the unit I bought had been overheated and appeared to have blown a head gasket. Otherwise cherry, I decided to go for it and ordered a gasket set for the top end as there was steam (white smoke) and alot of water exiting the tailpipe. The machinist mentioned that the 1.3 was known to burn exhaust valves and as long as I had it torn down I should replace them and have the intakes reground and the head surfaced. Had no idea the gasket kit was so damn expensive!

Anyway, there was water coming out the #1 cylinder plug hole prior to turning the wrenches. After all was done and said I fired it up this afternoon only to notice what appeared to be more steam and water exiting the tailpipe than when I started! No water coming from any plug holes, but there is an accumulation of the 'white muck' on the underside of the oil filler cap. If I remove the thermastat the steam and water slow to a bare minimum, when reinstalled (new thermastat) the steam gets to flowing pretty damn good.

I'm suspecting there's some kinda leak on the intake gasket side of the head??? I'm 99% convinced that the head gasket isn't/wasn't the culprit here. Any info would be much appreciated on this end as I'm a little wet behind the ears on the foreign vehicle side of the wrench, lol.

Thanks in advance,
1auminer

Makes me wonder if the head is cracked. Did you have it magna-fluxed? By the way, welcome aboard.

Re: Water/steam coming from exhaust

Did you have the head and block surfaced to make sure they are square? This should be done especially if it has been that hot.

Re: Water/steam coming from exhaust

A cracked head was my first thought when I bought it, but I had the head surfaced, Zyglo'd for cracks, new exhaust valves, etc, etc.

I'm almost convinced it's in the intake manifold gasket somewhere as I left the carb in place and fought the tight spaces to get to the bolts/nuts.

Thanks for your input on the matter...it's much appreciated!

I had that happen on my old motor, turns there was a gouge in the intake manifold so a little water was seeping in. Lance
