I just did the headgasket less then 100 KM's ago.. Last night a huge coolant blast came from somewhere and soaked the intake side of my engine and its blowing huge white clouds from exhuast, the coolant res is bubbling like hell and the engine is running a bit rough. Seeing as it was only done around 100 km's ago should I try retoqring the headbolts? or just tear it all down again?
recently did HG, now possible BHG

Make sure it is a BHG before you tearing into it. I agree the symtoms are pointing there. Napa part #700-1006 is one of the best tools for diagnosing a BHG. Can also inspect plugs and perform compression test but those arent as conclusive. Best of luck either way.
it certainly sounds like a BHG but ya never know. Leak down test and compression tests are great, leak down test more so as it's specifically designed for BHG diagnosing whereas the compression test doesn't really come up with a useable result a lot of times.
If it its a BHG it may be an easy fix once you get into the engine, if you recently did the job it may not have been done correctly, or may not have sealed properly, or it may have been a defective HG, Good Luck with it, those are the worst thing short of a piston melting or a rod dropping threw your oil pan IMHO because they cost almost as much as a rebuild in some cases. Good luck man.

If coolant is getting into the intake system like through your turbo or into the IC piping or intake it could do the same thing but I doubt it since its steady, I'd say 99.9% it's a BHG but I am not there so I don't know how good a job you did on the HG and I can't see your car running, I'd guess BHG obviously.
First, check the coolant lines that run to the TB and ISC valve. Might want to check the inside of both to make sure there is no coolant leak.
What gasket was put on? What bolts? What torque value? What prep work was done before putting the gasket on?

Actually, Toyota recommended that techs use 150-200 grit sandpaper on sanding blocks to prep engine blocks and heads when doing warranty head gasket repairs.
Yeah...and unless you are very, very careful about using an even, circular pattern, you can create a low spot. The head is even easier for this to happen. Then you need to check the block and head for flatness. Otherwise you are asking for trouble.
I'd use a fine Scotch Brite pad and solvent, but never sandpaper. Too easy to screw it up...and you can get grit down the oil/coolant channels unless they are blocked off and cleaned before you install the head.

I didnt say it was the greatest idea. Just what Toyota had advised to their techs. Actually it was in response to someone messing a head up with a 2" Roloc disc on a die grinder. Using the Scotch Brite or sandpaper both pose dangers unless proper precautions are followed.
actually, I only sanded using a few sheets. My brown car I sanded the fucking thing till it was a mirror finish and its been running great for the past 2 months (around 6000 Km's).
I will check those lines tonight. That could be sending coolant into my cylinders?
PS: does anyone have a pic of the exact line im looking for?

Could if the TB was cracked, or there was a problem with the CSI, as that is the only lines that go to any intake related things. The line that goes from the CSI and returns back to the block under the intake manifold has a small copper ring on the intake gasket that might if leaking suck in some coolant.The bubbling in the resivior is a different story.casing said:
