Re: Am I ready to install my headers?
Did you have to heat the exhaust manifold bolts to remove them?

This may be redundant but: Here's a suggestion: remove them with the heat shields attached. It takes removing the middle & back fenderwells, front wheels plus jacking the engine (2x motor mount bolts, air duct, & MAP bracket) up & down. You have to get at the bolts from both under & side. Requires/easiest-with a SHORT, ratcheting, flex-head 10mm open/box end wrench (use leverage to break bolt free initially if needed) plus a 10mm socket with assorted extensions & u-jt. Oh, and patience. With both manifolds off: I would double nut each header stud (one at a time), remove it, coat it with thread sealer, & replace it prior to header install. Ted |

Re: Am I ready to install my headers?
Alright.
Driver side is all done. I managed to put 15 out of 16 bolts. Should I do my best to screw the last one? It is doable, but pretty hard. I did not need an o2 sensor harness extension. I had to (barely) use the hammer on #1 pipe. Also, I did not put the locking washers of the Stage 8 bolts. Somebody somewhere said it is better that way. Was he right? Is it me or passenger side seems to be trickier? It seems to be a pain just to unplug that o2 sensor. Is it safe to unscrew some of the oil pan bolts (2), will I need to put some kind of seal afterwards? Is the dipstick bracket only holding with one bolt? Is it a big deal if the asbestos sheets touch the headers? I did read somewhere that I will need to cut a heat shield... I did not cut any heat shield. Should it be a concern? Thanks for your help guys! |

Re: Am I ready to install my headers?
Header gaskets will shrink a bit after a few heat/cool cycles requiring bolts to be retorqued - reason for avoiding locking tabs. Except for one bolt behind the dip stick tube. One bolt will be inaccessible after the dip stick is installed. Use a locking tab on that bolt.

NO. It's held with TWO. The reason for using the 'stove bolt' provided with (my) bracket is that square ~ 5mm long shank under the bolt head slides neatly between the prongs of the dipstick anchor tab. When the nut is drawn up tight, the tab, with the help of the stove bolt shank, becomes quite rigid; securing the tube to prevent up/down movement as the dipstick is removed and reinserted. For that reason, I suggest the bolts at each end be installed loosely (at first) to align everything, and then snug up the nut on the dipstick end of the bracket first as the header bolt will index the bracket angle as you tighten the other end. (Trrrrust me! Twaz all thought out long time ago!) Quote:

Re: Am I ready to install my headers?
Paul, thanks for all your answers. My only concern now is the dipstick bracket. Didn't see the 2nd bolt yesterday. Hmmm...

Re: Am I ready to install my headers?
Thanks secondchance and Scrrem, I did not see your posts this morning. Too late for the seal though, (I've already done driver side). I will (try to) put locking tabs only on bolts behind the dipstick bracket.
Paul, there wasn't any 2nd bolt that holds the dipstick bracket. Should I put your homemade bracket before or after installing the headers? The grommet was worn, but still there. Could have reused it. How about the heat shields guys? I did not cut any heat shield yet. Did you? |

Re: Am I ready to install my headers?
Alright,
Headers and chip are now installed. I did a 40 miles ride and 90% of the Stage 8 headers bolts became loose. One of them felt in the street. I just tightened them back. I hope it won't become loose again... |
