What is going on with my Disco, Engine? Transmission?
Today when i started up my disco (1998 4.0L v8i) It started quick but idled rough. Then i started backing out of my parking space and there was a lot of vibrating. It felt like i had a flat tyre, but i didnt. So i just started driving. (i only needed to go about 1/2 mile or so) anyways, it was shifting wierd and when i gave it a lot of gas it was jerking a lot. It kind of felt like it might be trying to start in 2nd gear? but i could pull it into first myself. But the point is that it seemed to be shifting erratically.
Anyways there was also somethin else. Not only was it idleing roughly, but it sounded like one of those old muscle cars when it was idling, i dont even know how to describe it, not the normal soft humm of the engine. Very hollow sounding if you know what i mean. Then i noticed that thick white smoke was comming out of the exhaust. (this after i had driven it the 1/2 mile)
I tried revving up the engine in neutral and a thick white cloude filled the area and quickly dissipated.
Then the damndest thing happened... After class, i went to drive it again, and it was completely fine! Idled smooth, transmission has always been a little jerkey lately, but normal compared to earlier.
Yikes whats happening?

RE: What is going on with my Disco, Engine? Transmission?
Sounds like you have a blown head gasket, if it happens again in the morning then you probably do have coolant seeping down into a cylinder over night. Check your coolant level, also if it smokes white again, get out and go smell the exhaust, if it has a sweet smell it will be coolant.
Rull of thumb is that if you have white smoke it is coolant and black smoke is rich running engine, grey is usually carbon build up being blown out under full throttle.

Can i drive on it for a little while?
aww.. god damnit. My parents are going to be pissed... Its theirs and i needed to borrow it while my saab was getting fixed.
Anyways, is this something i can drive on for a little while, or is it damaging to the engine? If i check and make sure my coolent levels are full should i be fine for a little while?
Also, i just had my exhaust manifold replaced (got rid of the ticking sound) and now there is more ticking sound. Is the head gasket problem making the ticking sound, or did he do a bad job replacing the exhaust manifold?
Should he have noticed that i was going to have a head gasket failure? I got to one guy for all of the problems.

Don't put any "goo" in your engine that claims to seal weeping head gaskets!!!
There are no short cuts here. It is really not a matter of if you will have a head gasket failure on your Land Rover, it is only a matter of when (typically between 60-80K miles). Once corrected ----and done properly, the head gaskets will last for many miles. The original factory build was where the problem originated. The aftermarket gasket designs correct this. Take it to a shop and have a leak-down test done, and a coolant analysis for presence of combustion gas. The longer you drive it the more you risk further damage to the engine internals.
example: head gasket replacement job at a good independent shop ---approx. $1500
overheating the engine, and then dropping a cylinder sleeve or two--means a complete engine replacement---approx. $6000

RE: Can i drive on it for a little while?
geoman is right... DO NOT PUT GOOP IN THAT MOTOR! I did that to my 20 year old Turbo Diesel 6 cyl Mercedes and all it accomplished was ruining a very new BEHR radiator. Talk to the guy in AZ, 98 RoverGuy. I just did head gaskets on my 1990 Range Rover County (same motor basically) and it took my buddy and I two weekends to do it!. I have the Landrover RAVE Manuals on CD Rom if that would help and would be more than happy to mail out a copy of those. It has ALL the correct torque specs as well as the how to's. Make a post in this site/forum and ask if there are any tricks to do after the fact. My old range rover was different the 2nd time around in that we left off the lower row of head bolts so as to not put undue torque on the bottom of the head which caused the failure in the first place. PM me or email me at aroohk@gmail.com and I can give either of you guys further input!
I would definitely say when you drove it, you cleared out water that had accumulated in the cylinders over night. DO NOT DRIVE IT! Check coolant levels and if need be have it towed to have it checked out somewhere. It would be worth the 100.00 diagnostic to know for certain it is the gaskets, than to guess, drive the car more, and kill the motor! Best of luck and let me know via PM or email if you need anything!

PS if you happen to be in CA i know a great Rover shop that would take good care of you, and could also offer some help in doing the gaskets. I live in the Orange County/So Cali area.

RE: Can i drive on it for a little while?
Your an asset to the forum aroohk. The thing is I own a 98 Disco 1, just like you boon. Today I have removed everything up to the intake manifold, exhaust and subsequent heads. I must say. It went rather easy. My girlfriend isn't here or I'd use her digital camera to capture it. Well, I'll keep ya posted if you think you can do it yourself, I can help with any advice. Rush!!!!!
