So I recently rebuilt my engine. Bearings rings block deglazed head revalved new hoses new gaskets. Everything. Bout 600 after everything was said and done. Car wouldnt start for a minute (read "no spark" frpm the forums for more info on that) but today I was driving and I noticed a miss fire thought huh must need a tuning. I was in there loosening the distributor and thought might as well check the oil stick. And sure enough milky white oil. Pulled off head gasket cover and more milky. One thing to note is that the engine did over heat yesterday when I went on a short drive but I parked and waited for it to cool. I also noticed an excessive amount of pressure when I took off the radiator cap. And a boiling sound in the back of the engine when it was hot. Just clues. But please any and all inquirys are wanted will my engone be fine are the bearings and valve screwed now I put so much work in to this engine. I just want CR'seXy to live again

Blown head gasket.

Will the engine be fine. I put literally like maybe 10 miles before I noticed it.

Do you think I got the hoses mixed up because that was a brand new felpro head gasket io can't imagine it popped so easy. I mean I did get really hot fast.

You need to 1. change your head gasket.  2.  Seriously check your cooling system.

too much ignition timing advance will blow the head gasket , Dave

[CRX'Y]

Do you think the head warped or cracked do you think the block warped or cracked?

That's like asking how long a piece of string is.  You need to take your head off anyway, so swing it by a machine shop and have them throw a straight-edge on it. 

[CRX'Y]

Taking head to machine shop. But what do you guys think the chance of my brand new bearings rings or crank shaft suffering any damage? I looked at the at the speedometer and I lyterally drove 9.3 miles before parking it.

[niccer]

No idea what the chances are, but I know coolant isn't conducive to bearing longevity.  New bearings are pretty cheap for these cars, so while the head's off and you're doing that work it might be a good idea to throw some new ones in there for piece of mind.  If anything, remove the girdle and inspect some of your big bearings and crank surface.  If they look okay you could probably get away with removing them all and giving them a wipe over to remove any coolant left on them.

The only bearings ill be able to check are the rod bearings without pulling the whole engine. Imma check the rod bearings and pull the head today

[Dirtcircle86]

If it's anything like my EW, removing/replacing the pan is the hardest thing about swaping bearings.  It's a tight fit on the flywheel end.  I needed to go race and could only get rod bearings in a timely fashion so I didn't replace the mains.  It came apart, but I had a blast doing it....  If i recall, you have to pull the main girdle to get the rod caps off anyway.  At least it was way easier to pull the girdle. 

 

My block was warped worse than the head.

If this is an SI motor another place to look on this is the engine oil cooler. If it has rusted out or cracked it would easily mix you oil and coolant. I used to be big on these but the older these parts get the more likely they are to fail. I'm leaning toward not running them anymore.

The bearings are still good, unless you ran it out of soap and kept driving, Dave
