90 XJ exhaust manifold $$$$

They are not necessarily saying that it will take 10 hours. They might be saying instead, that they charge $100 per hour, and that it takes 6 hours. I haven't done this job, but I have looked under the hood of an XJ, and I am thinking that there isn't much room under there for hands and wrenches. Then you have to add in the complications of frozen sixteen years old bolts and studs that will break off in the head. Whatever the reason, your local shops seem to be in agreement.

Now if this XJ has a four cylinder engine, then you might be having your leg pulled.

1. I used to run a muffler and brake shop.
2. I've done a ton of those.
3. We charged around 5.00 (back in 2000 was the last one).
4. It isn't hard to do. The hardest part is disconnecting the manifold from the downpipe without ruining the doughnut gasket there. It's around 18.00 bucks.
5. If memory serves, it's about a 4 hour job.

CDawg1506 did pass the time by typing:

If your relativly good with tools it is something you can do yourself.

It does take some time, took me about 4 hours if you don't count the time I took to replace the superchargers spider gear. Probably could have done it in less time but I'm a tad anal about cleaning and torque. That and some time cleaning out the intake rail and grinding a bit on a motor mount. (banks aftermarket was an "almost drop in")

For $650 you can buy a nice assortment of quality tools. Or beer.

I did one for a friend on a 91 it took me 5 hours and 4 beers I am a light weight.
