I just cleaned the EGR ports on my 94' EX. I broke a bolt to the EGR runner (chamber) the manual calls for 17 lbf-ft. (foot-pounds?) The bolt broke at 10 or 12 ft-lbs. Has anyone else had this problem?

 

I just figured out the problem. The stupid manual reversed Nm and ft-lbs. It should be 12 ft-lbs, 17 Nm. Mine may have broke around 15. I'll get 5 new bolts tomorrow. Hope this saves anyone slse from a broken bolt

 

What manual are you using?

The 94-97 Honda Accord shop manual, that I always copy and paste my answers from, says those EGR Chamber bolts are to be torqued to 8.7 lb-ft (12Nm).

 

The Honda Manual with 1379 pages. It's a pdf. I downloaded it just after I bought my car in October 08' It's full of mistakes. Is yours an update? Is it an actual manual or a file like mine.

 

I have the PDF file with 1379 pages as well. I found the specs on pg.173 (9-2) I have all of the 96-97 supplements as well though.

 

Thanks Ghost. I got my info on page 297 in the fuel and emissions section. There is another screw up on the bottom of that page. The Nm value should always be higher than the ft-lbs value. Check it out.

 

Yeah, I tend to get my tq specs from the sections directly related to the parts. I tend to use the Fuel and emissions section just for trouble shooting and PGM-FI related stuff. There are a few other typos and errors that I have found over the years. They aren't perfect, However, they are probably the best reference manuals available for the price.

 

Yeah free. I have read some of your other posts and you seam to know your stuff. Do you know why the Honda 4cyl. has a balance shaft? Is the crank not balanced? Did they omit it in future models? I did a timing belt on a friends 2003 beetle, one belt no problem.

 

Yes the crank is balanced. They use balance shafts because even though the bottom end is balanced. The opposing cylinders, in the I4 configuration, when turning are not always balanced to each other. Thus giving a vibration to the engine. IIRC the technical term is second-order vibration. That is why the balance shafts rotate at twice the engine RPM. to try and counter/silence the vibrations. The balance shafts don't actually balance anything, they more or less are there to silence the vibrations. There is no way to actually eliminate these vibrations.

If you leave the BS belt off you will still be able to drive the car with no fear of self destruction. They were mainly put in these engines to appease the old folks that usually bought these cars. From what I can see it serves no real mechanical purpose.

I guess according to some, my engine is going to be a handful of vibrations compared to a regular 2.2L. The larger the displacement (bore & stroke) the greater the vibration. Where I have eliminated my balance shafts, I guess I might feel a bit of a rattle. I never felt much when I removed the balance shaft belt on the stock 2.2l for a month though.
