course of action-engine advice needed

RE: Re: RE: Re: RE: Audio question...

ok, I have an 84 cj7 4.2 T5 that leaks oil at the rate of about 2 quarts a day. the engine has 186,000 on it and instead of spending even more time/money trying to plug all the leaks I am going to just drop in a new motor.
I want the howell TBI for sure. I have helped install/seen in it in action on a friends CJ and I believe it to be worth the cash. my main question is...would buying a shortblock, swapping in a 4.0 head and running howell tbi cause any compatibility issues? if anyone has a good writeup on a similar situation I would love to read it. I am also open to other suggestions. my goal is to improve idle/mpg/consistency and if I get a few more horses out of thats great too. ive thought about using the mopar MPI but I dont want to spend that much money on FI so thats out. thanks! Dave

RE: 249/242 swap

www.bustedjeep.com has got a good writeup on a 4.2 rebuild with a 4.0 head. On the last page they've a list of links that you might find very helpful. I didn't find any writeups dealing with the Howell kit, but I didn't look very hard, just Google it! Best of luck to you.

RE: Re: RE: Re: RE: Audio question...

It would be cheaper to just swap in a 4.0L, and it would have more power than the tbi 258 w/4.0l head. If you would prefer to stay with the 258, however, I don't think there would be any compatability issues with the parts you listed. For the price of the tbi 4.2L, I bet you could build a 4.6L stroker and have the best of both engines all in one plus a ton of power. It's really just a matter of how easy you want the swap to be.

Update Sept 16th 2005

I dont want to lose my low end torque with the 4.0. I am going to look into some stroker 4.6's though...i like that idea! Im trying to just make a nice simple swap over a weekend because I drive the CJ daily for work. maybe a stroked with the TBI might be the ticket...although come to think of it, that would be detrimental to my need for better mpg

What about weber fuel injection and ignition?

The induction AND ignition is fully programmable with a windows 98 interface. Howell and Mopar dont have this advantage.

thats a really nice setup but close to 3k...so its out of my range for the project. thanks though!

RE: Toyata making I car I like????

yeah kinda pricey huh? lol bad enough gas is $3 a gallon now I add another $4 a day in oil. I drive it alot; roughly 100 miles a day and it just pours out of it. back of valve cover(which ive attempted to fix twice with new valve cover,right stuff sealant etc...) rear main,front main and i suspect a little around the oil pan. my pcv system was backed up with blow-by and it sprung leaks everywhere with the pressure buildup. fixed the pcv but the leaks remained.
