Re: '99 TJ redline after header install (update)
For those who haven't followed the thread, a brief history:
Installed a new header on my '99 TJ 4.0L 5sp this weekend. Screwed up
the first attempt by misaligning the intake manifold, and it wasn't
seating properly on the cylinder head dowels, creating a massive
vacuum leak. The engine would attempt to rev to redline when started.
Second attempt resulted in what appeared to be a good seal with no
vacuum leak, but RPM's slightly high at 1000-1200.
Now the update: Drove it around town a bit more yesterday, and took it
on my commute to work today. Idle is now sitting at 800... think the
computer needed to adjust for the new exhaust flow or something? Heck
I dunno, but I am one happy camper. Sure is nice having the power that
the old cracked exhaust manifold was sucking away! Since the crack(s)
started small and only gradually got larger over time, I never really
noticed how bad things had become (other than a lotta noise hehehe).
Anyway, I'm going to try to get some pics posted of the old
manifold... the cracks are outrageous!
Thanks again for everyone's help.... very much appreciated!

Give it a week or so then re-torque those bolts after everything
settles in. It's also a good idea to check them every so often for a
while - saves having to find the leak again.

Thanks, Will. I plan to.... the installation sheet mentions exactly
that. Something along the lines of re-torque after one week, then
again after one month. I'll make sure I keep on it. :-)
