Search Results for ‘intake manifold’

I have a 98 ZJ. I've done quite a bit to the engine with more to come. Trying to squeeze as much as I can out of a 4.0 without stroking it. My BIG question is about the intake and exhuast. I've replaced the intake with a 99+ but had to do a little percusive maintenance to make the new exhuast...

Hi, Looking to get a 90's 4.0 HO intake manifold. Is there a preferred year, cast, model# etc? Also, what adapter part# brand carb mount do I need to put an MC2100 on it? Is there a how-to for epoxying the required ports or where does anyone know of a preferred shop/vendor to have it done...

Hello, I am new to the forum and this is my first time posting, but I have spent dozens of hours scouring every forum I can find for an answer to the issue I have, but this is proving a hard nut to crack... I bought a 92' Jeep Cherokee Briarwood in March of this year as a daily driver and for...

Hey guys, first post so bear with me. I have a 1977 CJ5 with inline 6C 4.2L engine. The body is in great shape, but i'm having some motor issues. It starts and runs, but backfires very often when I give it some gas. The muffle is "footballed" out so I know i'm replacing that ASAP. I've been...

I'm looking at a Jeep with a 304 the owner states the "valley pan" gasket may need replacing. What issues come with a bad "valley pan" and gasket. I read several "how to replace" on MOC's post but just wondering if there could be a bag of worms behind the problem?

Ok so ive done a bit of reading on doing an intake swap on my 4.0 95 zj. Only thing im wondering is would it be best to keep my stock injectors (new of coarse) or get ones that went with the newer intake. I have the gear to revamp the fuel psi as needed. I just keep getting gray areas of info...

I was on EBAY checking out 2150 2bbl carbs. I am installing a 77' 360into the 87' Grand Waggy with my 87' intake manifold so I can use the 2 bbl carb it originally came with, rather than the 4bbl on the 77'. My 87' block is all torn apart and really needs a full rebuild, that will be later. The...

1999 Jeep TJ 4.0l. Replaced exhaust manifold due to broken pipes and replaced with new gasket according to chilton manual. Did not start 4 bottom bolts for intake manifold before putting it in place. Set intake in place and worked forever trying to start all bolts in bottom. Finally got all...

Hey guys, Back again with another clueless question. I just finished replacing a bunch of parts between the two manifolds. With the jeep all buttoned up I crossed my fingers and turned the key reluctantly. It did ok, reved to 3,000 then came down to 2,00 and now its sitting around 1,000 -...

I have a 77 CJ7 with a 304. The PO installed an Edelbrock intake and Carb. When I got the Jeep it leaked oil like I don't know what. I removed and reinstalled the intake yesterday and used Edelbrock gaskets. The instructions said to use the valley pan and to use a 1/4 inch bead of RTV to...

First time posting so if I mess this up let me know. While replacing a cracked exhaust manifold on a 92 YJ, I seemed to have misplaced a small junction for vacuum hoses that was connected to the intake manifold adjacent to the intake manifold inlet and throttle body. I have a service manual...

I just replaced my cylinder head. Started it up for the first time a few hours ago. It ran a bit rough and then idled all the way up to 3k +/- a few rpm's. Won't drop back down to normal idle. I checked the codes and I'm getting P0505, IAC. Now, I put my hand over the throttle body and the idle...

I have a 97 XJ 4.0L that is at the moment fully stock. I have heard a lot of talk about the 4.0l engine loosing power with bigger high flowing pipes. I would still like to increase my HP and torque. with the mods listed below, does anyone have any info/experience with choosing the correct pipe...

Hi folks, new to the forum but have referenced this site many times for info. Great resource so thanks! I am stumped!!!!! I just moved from the southwest up to Connecticut and now I actually need heat for the winter! But my heater is not working! I can't find a coolant low diagram to save my...

I want to convert the stock 2BBL carb and manifold to a 4BBL. Any suggestions on what to get as far as the combo is concerned? I am sick of tinkering and trying to adjust my holley 2bbl carb that is on there now. Any help is appreciated.

Maybe it doesnt matter, but Ill try to ask. I have 80 CJ-7 258 and I have my intake manifold and exhaust manifold off. The new gasket to attach them together is flat on one side and dimpled on the other. I am re using the intake manifold but installing new exhaust manifold due to many cracks...

I have a white smoke coming out of my jeep, its isn't really thick, and it doesn't appear to be blue. I don't think I'm burning oil, I've checked the oil level and it's the same as it was a month ago. I'm not sure if i just haven't noticed it before or if its becoming worse and more apparent...

Hello i have a 97 Wrangler TJ that i have just changed the exhaust manifold on due to me splitting a primary tube clean in half. I pulled the intake manifold and exhaust manifold and replaced it. I put everything back together and now when i start my truck it revs up to between 3500 and 4000...

So, first I wanted to get some opinions.. maybe some answers. My Jeep lately likes to drop to 0 RPMs and stall out after starting and leaving her in park. When I put her in gear (R or D) she sputters, but then runs fine.. Any ideas what it could be? I checked the fuel pressure, and that's fine...

Big thanks to Mallcrawlin user DJJordache and the information contained in his thread, found HERE. His thread contains the dyno data and comparisons of the older manifold vs. the new manifold. But I feel like there were a few portions that were unclear and there is a lot left to you to figure...
