Re: Any Decent Jeep Repair Shops in Orange Co, CA. To Recommend?
 

Manifold is fine (replaced multiple times - Banks TorqueTube a few
months old). If let to idle for a long time, eventually, one of the
lifters begins making a loud tap-tap-tap that sounds like a small hammer
on metal (like it's low on oil). It comes and goes randomly, but only
happens after idling a long time. That's my sticky lifters. When I'm
driving, I hear exhaust noise, same as if I had a cracked manifold, on
other side of firewall in front of my feet. I thought that my manifold
had cracked again for the fourth time, but it's fine. Cat converter and
Flowmaster are fine, too, but noise is right at engine. I've spent good
money too many times paying labor to replace the crappy Banks manifold
that keeps cracking, but this time the manifold is fine. I used to have
more power, and pulling onto the freeway at 65mph (3200-3300rpm) was
never a problem. Now I have to floor it to develop 60mph when I need to
merge. Sometimes it gets there, other times I'm lucky if there's light
traffic and I can get in at 50mph. Eight months ago this engine ran
great, like new, and delivered between 13.5 and 14mpg. Now I get 9.5mpg
since winter. I had noisy ignition (detected on AM radio - I suspected
bad cables), so shop changed plugs. Cables, distributor cap, and rotor
were said to be fine at the time. Tires are 33s, gearing is 4.11. My
performance is down, my mileage is down 17%, and the YJ is noisy.

Misc. unrelated work performed on YJ in last 9 months:
replaced tires - old 32" BFG ATs, AR aluminum rims, with new 33" BFG
ATs, AR steel rims. Yeah, added weight.
replaced old Con-Ferr double tube bumpers with Warn rock bumpers with
tire swing-out. Yeah, another 50 - 60 pounds for the swing-out.
replaced brake power booster and rebuilt 2 brake cylinders, changed
brake lines. Now it actually stops.
replaced old ---- Cepek shocks/3" springs with new Skyjacker 4" springs,
RS5000 shocks. Still rides like hell (yeah, I should have gotten the
RS9000 shocks).

Odometer difference doesn't account for gross difference in mileage -
I've checked with GPS unit, actual vs. recorded looks like about 95%,
not 83%.

I'll ask what the shop found when they checked the compression - they
say that they checked, but didn't report results on the receipt/summary.
