I'm trying to take apart the manifold, o2 housing and turbo. basicaly 8 bolts all together. Man those mothers are tight. Is WD40 sprayed directly on the bolts a good idea, then just keep torquing until they start to unscrew?

 

Nothing wrong with a spray of wd40 with torqueing it.

 

i would personally use PB blaster. you can get it at wal-mart. great stuff. let it sit for about an hour or 2 before you start wrenching. they should come right out. hope this helps.

Wd40 is not really the best choice for a penetrating oil. Probably the most common solution would be to buy a can of PB Blaster...Works great, I use it at work. Should be at any "auto parts superstore" place. I would also highly recommend sili-kroil, but you would have to special order your own. I used it when I was working as an aviation mechanic in the Coast Guard. -Gabe

Absolutely use PB instead of WD!!

And remember, fast torquing > slow torquing. In other words, use a quick/sharp motion rather than an extendedly long slow motion when trying to unscrew those things.

 

thanks guys

 

BTW I could not find PB at pep boys, but got it at autozone.

Accept no substitutes!!

 

+1 for PB, I like liquid wrench too

 

What has helped for me is spraying everything down with PB, turning on the car for a few seconds (10-15seconds), respraying, waiting till everything is cool to touch THEN unscrewing. For sure everything will come off like butter.

 

man, if i only read this thread earlier. I almost broke my wrist just taking off the bolts for the exhaust .

 

I've got a spare manifonld, o2 housing and turbo, so its not in the car. I'm going to pick up the PB tomorrow and work it out.
