Are you getting a check engine light? What happened with the old gasket? If it came apart and went down the pipe to the catalytic converter it could be wreaking all varieties of havoc.

What is the cause of my Jeep SRT 2007 engine light on? is it a blown head gasket?


Do a compression check it will give you a sign if you have a blown head gasket also check to see if your oil is frothy or has water in it same with anti freeze does it have oil in it these are signs of a bad head gasket . You might want to check your sensor on your crankshaft it isn't expensive maybe should have a mechanic with a good reputation check it most that are NAISE are very honest.

My 98 Jeep Grand Cherokee loses power going it uphill and when I accelorate it sputters and slows down.


it sounds like you may have a clogged catylic convertor in your exhaust system. after the car has run for a while look at the convertor under the car sometimes they will get red from the heat. or even the exhaust manifold could be red. this just happened to my suv. to confirm that it was my convertors I drilled a 3/8 in hole in the exhaust before the convertors. then I test drove the car going up a steep hill and the car ran fine no more lack of power and the engine ran smooth. if this is not the problem and you drilled a hole in the exhaust pipe then just go to a muffler shop and they will weld the hole closed for a few dollars. good luck

check the coolant level. check thermostat for correct operation. Have a compression test done to check for head gasket or cracks . All indications are that the motor is overheating badly.

Jeep grand cherokee choking problem after a few minutes.


Check your idle air control valve. Sounds as though it may be the problem. The other item could be the TPS, but I doubt it because it would idle poorly all the time even after warming up.

Any leak is not right. Try tightening the flange slightly - do not over tighten. If the leak persists the gasket will need to be replaced. I assume you are speaking of the automatic gearbox oil cooler.

I have an exhaust leak at the manifold. Do I need to replace the flange gasket and the O ring. My question is will I ruin the flange gasket when I disassemble it to replace the O ring?


Yes, any type of gasket or seal on your exhaust will not reseal properly. Exhaust seals have a "crush seal" . Once crushed will not be reusable.

How to properly relieve the fuel system on a 98 jeep cherokee?


On the fuel rail there is a small cap that you will remove, inside is a schradervalve(like on a tire stem)depress it with a small screwdriver to relieve pressure FUEL WILL SPRAY,NO SMOKING,USE CAUTION, be in a well ventialated area. NO OPEN FLAMES.

Modern head gaskets do not require additional sealer or retorqueing. Follow gasket maker recomendations. and torque as recomended by Jeep.

Exhaust mod may alter your torque curve and possible give you a few mpg's.
The key to performance in any engine is essentially you can't put in more than you can get out of the other end. KN air system will remove some restriction on intake end, and exhaust will remove restriction on the other end. However, in the middle you still are dealing with the same intake manifold, air inlet (throttle body) as well as cam & valves. (sort of like two funnels with the small ends, end to end) Any changes in these areas will mess with computer parameters and that requires a lot of research to overcome, as well as a hefty $ investment. (before control systems got so complicated, you could just bolt stuff on and go) Good luck and be careful with your project!!
