Damn exhaust manifold wont come out.

Stevo1111 · 8-13-08, 7:45

I need to remove the exhaust manifold so i can repair the stripped threads but the four bolts under the manifold connecting it to the turbo wont budge, iv tried hitting the spanner with a hammer hard but nothing seems to budge. And its a very confined space so am unable to get any breaker bars in. Any ideas? I must have this done by tomorrow after work so can i please have quick detailed replies? Thanks alot in advance.

I would soak them with PB Blaster, and instead of a breaker bar, I would interlace two combo-wrenches and use as a breaker bar

you should remove the entire turbo assembly ( mani turbo & o2 housing) as one unit & disassemble it out of the car....the way you're doing it, is gonna take way longer & is virtually impossible

**zlyricist** · 8-13-08, 13:53

indeed. unbolt that o2 housing and pull it all out

If u remove the hole assembly don't forget the mount bolted to the bottom of the turbo.Took me 40 min to realize thats why it wouldn't come off.

**cuJe5ter** · 8-13-08, 16:10

yeah u should always pull out manifold+turbo out as one. disconnect the DP from the O2 housing, unbolt the support bracket from the bottom of the turbo.

soak the manifold bolts with pb blaster or just use some freeze off. remove the radiator if you havent yet. that's goign to cause some problems if u leave it in there especially if u dont have a firm grip on the assembly. last thign u want is to yank the manifold off and have it put a giant dent in ur radiator.

ah ok then i will do that. So i have to disconnect the two hoses from the turbo and the exhaust pipe at the bottom?

**Keeloh** · 8-13-08, 18:32

Yes you got to disconnect the 2 water hoses and oil return hose and the exhaust pipe bolts.

skinnyvince · 8-13-08, 18:40

I never really worked on a car before but it was pretty easy 4 me.But the hoses where old and dried out and crumbled to pieces but i had sum hoes from my last pyp visit that worked.

**cuJe5ter** · 8-13-08, 18:46

yeah chances are ur water hoses (for the turbo) and the oil return hose are going to crack. be ready with replacements or call mazda and order some.

**Keeloh** · 8-13-08, 18:54

Those hoses are cheap at the dealer http://www.mx6.com/forums/1g-faq-par...rn-gasket.html (Turbo Hoses (Coolant and Oil) and Oil Return Gasket)

cant get the turbo off, no bolts will budge. This is really frustrating and i got no lubrication on hand. How am i going to do this? It needs to be done within a few hours. I hate cars

**Keeloh** · 8-14-08, 3:51

Don't use the 3/8 inch drive rachet use the 1/2 on the exhaust manifold and also on the down pipe and put some pb blaster.

Stevo1111 · 8-14-08, 8:00

got no pb blaster. dont worry iv fixed it, all i did was replace the gasket and put some extra washers on the bolts, no more leaks. Phew! Thanks for your help guys.
