Hey Guys. Well. Looks like More problems with my car. GOod thing I have a whole lot of patience. Heres whass going on. I drove the car around the corner to my school. As soon as I got to the school. The car died on me in front of all the students. There was white smoke coming under the hood. The smoke was coming from the PASSANGER SIDE of the motor. THere was OIL leaking on the headers. I could not figure out where it came from
I let the car sit for about in hour. Started it up which was very sluggish. And drove the car home.

Now the GOOD PART
WHile Dirving home. THERE was a GREAT DEAL of WHITE SMOKE coming from my Pipes. (IT looked like a nascar on the circut with a blown motor. Know how sometimes there driving and BOOM a puff of white smoke just trials the car) Well thass what happen to me.

I got home POPED the hood. OPened up the OIL cap. And there was the Brownish Milkshake color and it was boiling. Just incase now body knows what happen to my car before. I had a blown headgasket. Thas what cuase this rebuild in the first place. My LT1 undergoed a GREAT DEAL of over HEATING that NIGHT TRYING to get it home off the FREEWAY.

Also to let you know before i went to school. I put water in the radaitor coolant resovoir and ketp the cap open just to see if the water will circulate when I start the motor. WELL what had happen was. WHen i started the car the water jump right out of the Radaitor cap.

SO Now I leave to ALL The experts. I wanna no what THE HELL IS GOING ON with this CURSED LT1. I LOVE the hell out of this car AND I will NEVER SELL IT. BUt I think I have a CRACKED HEAD. IF I do. I wanna no what kinda of HEads and INTAKE I can go with to match good with my 224/236 nitrous CAM SO its ALL you guy right now. PLEASE I NEED HELP. im going to put my LT1 up for a while. IF you think somtihng can be done please reply. IM CONSIDERING Stroker motor. Thanks
Chris

 

IM also Scared that my bearings in the motor might be gone to but I hope not. IS this possible? IM also hoping that DO NOT have a Cracked BLOCK wass the likley hood of that.

It doesn't sound good. You can do a bleed down test to see where the leak is, but it sounds like its time to pull the beast and disassemble it and take it to a good shop to test the heads and the block. Kevin

 

milkshake color would mean water/oil mixed. and if you are smoking allot out of the pipes that means blown motor unless you are getting it all through the intake somehow. drain your oil, and see what seperates. you could also get a leak down tester and see what that tells you. but yeah, not good, not good at all....

 

Hate to tell ya.....but it sounds like youve blown another head gasket. Did you have the heads surfaced before you replaced the head gaskets prviously? All the overheating mostlikely warped the heads.

 

OK I indeed did Get the heads REsurfaced when I put the new gaskets on. Along with a new cam and some other stuff. SO what you guys are saying right now. I need new heads. OK IM pretty certain of that. BUt im worried about if my internals are OK. IF there not. OR if you guys give me any speculation of it. IM building the STROKER Thanks

I've flooed motors with water before and I was always fine (bearing wise). But I never tried to drive any of those cars while they were in the milkshake state. There's really only two ways to find out if everything is ok.

1. Fix the leak, dry everything out, cross your fingers and start it up.

2. Pull the motor and check the bearings yourself.

I think I would be looking at pulling the motor out and doing a full rebuild.

 

YOu see. THe shady PART of this. IS that IT was a REbuild. NEw Gaskets. RIngs. Bearings. Everything. I had the heads resurfaced. IM telling you right now. IF i have to come close to pulling those heads off. WHICH Im pretty sure I have do.
Its time for stroker. New block new LT4 heads. eTc..

Golen LT1 stroker either long or short block. Very reasonable.

 

Dude, it could have been as simple as a little bend or scratch in the gasket which over a few heat cycles could have caused the gasket to fail. The first time it happenned to me was with a felpro intake gasket that split on one of the water jackets. I could have been the one who nicked it somehow or it may have been a defect. Point here... just cause it's new don't mean it will work. Anyway, enough philosophy. Go ahead and fix the broken gasket be it the head gasket or the intake gasket. Change the oil and let it run a few minutes and then change it again then just let the thing idle for about an hour with the oil fill cap removed and you will steam the rest of the water out.

Trust me, building a good stroker isn't cheap.

You do know about bleeding LT1's etc right? Not a real good idea driving with no[or loose] radiator cap?That'll look like old faithful real fast.... tho it does appear that you have more problems than that...
Did the engine ever run right after the rebuild?
Or did it just act up after you left the cap off?
If so, try filling, put the cap on tight and bleeding it correctly...
you might get lucky.. if you didnt drive it too far..
That emulsified oil doesn't sound good tho[it means water in oil]

 

If you did really overheat it, it isnt too hard to cause the heads to lose their hardness/heat treat. If you ever think you might have lost a head gasket, STOP running the engine. You can resurface a soft head, but if it cant distribute the clamping force across the gasket it still wont seal, no matter how flat the surface is. If you've ran it alot like this, the bottom end is probably nearly trashed as well... It's probably time to tear it down again. Have a machine shop hardness test the cylinder heads out on the deck and in between the adjacent exhaust ports would be my suggestion.
