I recently purchased a b18b1 integra that's boosted by the previous owner. What a nightmare, I know. Even worse I'm a noob to boost. But for the price I couldn't pass it up.

My question is this, the car runs, and drives, BUT smokes horrible white smoke out of the back and from the wastegate dump(which needs relocated). Yes, I know, white smoke is water/coolant, which says headgasket, but the question I have is what else could this be? It doesn't overheat though.

The compression is horrible. 70 all the way across.

 

If smoking white, and compression test was horrible, well my friend, your head gasket is screwed up )-:

 

Well that doesn't sound too bad! I'll fix it sunday, I'm hoping that is the only issue.

 

Is there anything else I can look for to confirm it's a bad head gasket? I wasn't able to get to it this Sunday because of weather.

 

Leakdown test will give you the most information, ie if the pressure from the cylinder leaks into cooling system its very likely HG is the culprit although you can never know exactly until you tear it apart as there are some other issues that can cause this just not nearly as likely

 

if you don't have a leakdown tester or access to one, just do another compression test, and remove the radiator cap and watch to see if the coolant moves at all with each compression stroke. if it moves even the tiniest bit, HG is blown. don't stand directly over it though, because it can launch our pretty hard if the leak is big enough.

If and when you replace the hg, make sure you bring the head to a machine shop and have them check it for straightness. anything more than 0.002" difference and you'll want to get it shaved. do not skimp out on this. the life of your next hg relies on it

 

H-T Code Pro Tip!

 

Well, I went to pull the head and when I was pulling the plug wires I found they were completely covered in oil in the 2 middle cylinders. I've never noticed an oil consumption issue though. Hmm.

 

check your spark plug seals under the VC if your lucky it could be as simple as that

 

I'm hoping so !!

 

I can personally say x2. Just did a HG on a friends single slammer and had to do it more than once. His was out .004" in the dead center between cyl 2 and 3. I told him the clearance and he still didn't want to have it shaved. A week later the HG blew out again. (probably just took that long for him to find it...)

 

Noted! I will have it looked at for sure.

 

Bad news! Found a crack in the block. Gonna look for a swap. I guess I can do some body and paint work while I search for a new engine.

 

where did you find the crack at?
