hahahah Just what i needed i installed the 2.3l Cams(its the right ones) and my engine started knocking not a nice tic but a ta ta ta ta ta ta ta ta tatat tata ta ta t at at a ta ta ta ta any one else have this problem?... man i gotta love that engine .... 9.5's at the 1/8 but i got greedy and look at me now
hurmmm wonder how much is a new crate engine ..
What did you do when you install the cams? did you change the lifters? they dneed to be primed. You NEVER EVER START an engine when it's dry. You have to make it turn but not start it. you unplug the IDI plug and start it to build up oil pressure and bring the oil up in the head.
Now, you said they are are the right ones, how do you nkow? did you mesure them or not? if you didn't, you can be wrong. Casting numbers on the 2.3 cams are the same for the Ho, Lo and W41 cams.

I have never primed the engine after a cam swap, never had any weird noise either. Also the casting numbers are also the same as the 2.4 as well. That is why it is very hard to make sure you get the right ones. The intake cam is not too bad because of what year it came out of.

How did you mark the timing gears during the the cam swap?

^ why mark the timming gear? if you can't figure out how to time a 2.4 engine, you should never touch and engine. Both cam gear have a hole tu put an M8 bolt to lock it around the 6oclock position and the crank has a dot to line up. If you can't time that, you're dumb.
You don't have to put the chain back the way it was, you set the timming when the 1 cyl is at TDC and both cams arenot opening any valves.

He didn't say that the engine was at C1 TDC. THAT'S WHY I ASKED! I DIDN'T ASSUME THAT THE DID SET THE MOTOR!

The thing is, you don't swap cams without any book to help you when you don't know what to do. First thing they tell you in the book to set the timming is to lock the cams and set the crank. It's the way you're suppose to do it.

Yea i followed the instructions on the book its prettty simple just align the crank straight and lign up the pin holes .... the reason i wanted to do the cam swap in the first place was because of my timing chain jumped because of the loose crank pulley..... anyway im try to put the stock one's on there does my engine have a chance ? will it keep knocking ? these arnt hydrolic lifters so how should i prep them before i set them in with the stock cam's ? and well i took off the cold air intake white smokes comes out of it (gas) im thinking that is it. .......i did everything by the book but i dont know ive never done it before dont know what it could be i never messed with a DOHC i messed with tons of 5.0's simple and easy .. thanks for helping me out im just trying to get it back to life and hopefully 75 shot. .... thanks again
Timing chain jumped?
Aren't these heads interference fit? If so, your valves and pistons are fubar.
yea well thats what i call it my pulley got loose and the little lock that holds the gear to the crank came off with the pulley therfor the gear that turns the crank wassent turning the crank with the timing chain / .. make any sense ? its the little triangle metal piece i call it a lock .. well yea thats what happened
Unless you both a set of solid lifter for the 2.3 with a set of lash, you have hydrolic lifters.

I dont believe that the stock 2.4 are hydrolic right ? im just basically putting everything back to stock .. i have to ride to college and no ride to my job... my other block shop.... i took off the took off the timing chain housing cover and well two of the chain guides were in pieces ... and the tensioner shoe was all the way in wasent gving any tension.. one more question how is the tensioner reset ? the tensioner says look at the book to find out how to reset it but it doesnt mention how to do it in the book. thanks for everything hope this works
Doesn't sound like you should be working on a 2.4, especially timing it......scary

Yea your right i should just take it to a mechanic so i can get screwed or better yet let me just buy a new engine .. you want one ? i got's lots of money all my expenses are paid especially the $17,000 loan i got for college im glad thats paid off in full ...
Theres only one way im going to learn and thats doing it my self and asking question's from experianced members espcially on these DOHC ....
Hey, all I'm saying is that before you start doing serious work on the motor, you should learn about it first. For example, hydraulic lifters. Don't doubt Mfk-223. He is a wealth of information in regards to motors. I never said bring it to a mechanic. It's awesome that you are learning about the motor by doing it yourself. There is nothing wrong with that. It's just a good idea to learn a little more about the motor before stepping into a big project. And don't start doubting the people on here, like Mfk. There are a lot of very knowledgeable people here.
And please don't begin to brag about how much money you have to spend, or how you paid off the loan for college. (No offense, but your English mechanics don't appear to be coming from a person that is a product of college.)
Anyway, back to the subject. Like Mfk-223 said, did you actually measure the cams with a calipers to see if they are the correct cams? That's where I would probably begin. Also, did you check your lifters before you reassembled them? Any signs of wear or cracks? Get back to us on that and we can take it from there.

well if you didnt catch the derisive paragraph i wrote then sorry for sounding like an ass. I have about 20 bucks in my pocket and dont have anyone to fix the car but my self . i Really have no doubts about Mfk-223 i read alot of his Forums and i know that he knows plenty about our engines. im just trying to get some advice waiting on an answer . ohh yea and i dont plan to become an automotive tech either im in my second year for architecture a UTA .... later and thanks
I don't want to high jack the thread or anything but my cams are also making that noise, but it only sounds like it is the exhaust cam. Mine didn't make the noise until about ten minutes of running. I marked a tooth on the cam gears and then a reference point on the block and installed them in the same spot. I belive to set the timing on these you have it at TDC and then the dowl type things on the cams should be right on top? But when I uninstalled the factory cams the exhaust cam dowl was more towards the back of the motor and not on top, could this be my problem?
well can yall please help me Time my car properly ? this is what ive dont so far ive installed the cam's and lined up the Pin holes to the one's on the on the timing chain housing. i bought a new tensioner shoe and its just stuck all the way in wont come out dont know how to reset it.... please i really need someone that has done it before ... i mean its sound easy but i dont know in the book it says if soemthing doesnt line up you have to rotate crank 90 degrees and the back .. ahh im just really lost please guy.. thanks ....
