Torque setting for the intake mani?

[dsobering47]

As current BMW tech, I can't say I torque everything, but I do understand the need to do it. Just because something hasn't fallen apart or wobbled itself to pieces, doesn't mean its perfect. There IS such a thing as over-torquing.

How about this:
Did it ever hurt to torque something correctly? How much time do you really gain from not torquing it?

I'm in disagreement that the only bolts worthy of an accurate torque setting are head/rod bolts. I torque everything related to the engine...especially anything that has a gasket surface or seal and prone to leaks over time. Flywheel bolts and lug nuts are always done...I've never had a warped rotor, even on my racecars.

Well, you need to understand that I very much so do know what I am doing.

I have NEVER torqued an intake or exhaust manifold, never a valve cover or an oil pan. No leaks so far. Just between my two current cars I've probably done 200 wheel changes. Not one time have I torqued the lug nuts/bolts nor have I EVER had a warped rotor on anything I have owned.

I do have real life experience working on BMW's and cars in general. Only 4 years at a shop but many more at home. On my S50 car every single bolt engine, transmission, and suspension related was put on by me. Hasn't wobbled apart yet.

If I was Jordan I would have already enjoyed a click of the ban button.

Now that I will give you...

E30 don't fly and planes hardly compare to E30 intake and exhaust manifolds. As said, you can go on enjoying your torque spec internet world and I'll continue using common sense and build me some white trash E30s.

Now the bolts holding the seat down, or the philips head screw holding the front ashtray down? who cares about those as long as they are tight and not rattling?

I do torque lug nuts and flywheel bolts etc but it's ridiculous and time consuming to torque every bolt when your elbow torque is reasonably close.

Yeh I just torque important stuff like suspension and brakes, head bolts ect. Stuff that wont cause death if it falls off cos it was not tight enough I just do buy guestimate.

wow Is this Jordan??

I do know what I'm doing on more than just e30's. I'm not going to argue with you or get in a pissing match with you over it. Think what you want or hold yourself in as high regard as you care to. Which is obviously pretty high. I've been around all types of cars, race and street, for over 30 years. First worked on an e30 in 1987.

When our plane gets its annual inspection each year....you better damn believe that we have everything done by the manufacturers specs....that includes torque values. FAA mandate.

Based on your responses, I am beginning to think you really are a misplaced redneck. The big boy comment?? wow haha

So you're telling me you torque every screw on every inspection panel on your cessna? Sure.

I'm with mr 325, any experienced tech knows torque by feel and doesn't torque every stupid bolt. I do torque lug nuts and flywheel bolts etc but it's ridiculous and time consuming to torque every bolt when your elbow torque is reasonably close.

I wrench on 3.5 million dollar fucking helicopters all day and we don't torque every single thing with a torque wrench. Obviously there are some critical items that you don't want to be off on where you use a calibrated torque wrench. But you'd be surprised how close you can get by feel once you've been wrenching a while.

My intake manifold requires more torques than your Honda produces.

Does anyone else have a tough time installing the nut next to the fire wall? Gets me every god damn time.

I always put a peice of paper in the socket to hold the nut in good. hand tighten to keep from stripping it out. Works like a charm


BTW you can over tighten the manifold and distort the oring's allowing unmetered air in to the engine.

[Myster-E]

ya think? Hopefully I'll never have the displeasure of riding in a car you've worked on then. Suspension doesn't matter?? How about lug nuts??? Gotta love warped rotors!! hmm. Flywheel? Pressure plate?? What about anytime you are running a bolt through aluminum? ie exhaust manifold bolts? and no worries about stripping out those oil pan drain plug threads right?


"they ain't loose or snapped so they gotta be a'ight"

Tighten quarter turn past loose and cross threads the tightest fit.

Ok, everybody simmer down now.

True, I didnt spec the intake mani bolts originally and didnt think too but I had a vacuum leak at the 1-3 area. I didnt want to take all apart again and wanted to make sure it was flush against the head...within spec.

[trackjunkie21]

It's not like it takes a few hours to torque it to 20Nm. You guys really can't spare a few seconds on your 'beloved' e30.
