Okay, so I pulled the valve cover off of my II about a month ago to try and diagnose my backfiring problem after I'd ruled everything else out... At that time I discovered that one of the rocker arms (followers? which term is correct?) was no longer in it's proper place beneath the cam... I purchased a new cam and rocker arm set along with a new set of lifters. I went to the books (Haynes and Chilton's) and got conflicting answers...

Chilton's Car repair 78-85 (includes 2.3L Mustang II) says I have to pull the head to swap cams
Chilton's Truck repair 86-90 (includes Ford 2.3L Engine) says I can jack up engine to remove cam
Haynes Mustang II 74-78 says I have to pull the head
Chilton's Mustang II 74-78 I can't find it right now, but my dad says he read what it said before I bought the new camshaft and doesn't recall it saying I needed to pull the head.

Anyway, Along with procedure I have another question, can I just put the rocker arm back where it belongs and save the cam swap for another day? If I have to pull the head I'll need more parts (gaskets, etc.) and I don't have the money right now. The current cam appears to be fine but has a few scratches in the lobe that goes with that rocker arm. The rocker arm also has a few shallow scratches. Would it cause any problems to just put the rocker arm back? Would it hurt anything if it came back out if I tried? I need to know...

I have a 1976 Pinto, which I run in NHRA stock eliminator. I change cams out in about 45 minutes without pulling the head. I use a floor jack on the oil pan to jack the motor as high as it will push the motor mounts up. I also have a little dimple I hammered in the radiator mount, so the cam will slip out. You may have to pull the radiator? I have never tried it on a Mustang II, but I would encourage you to try it. You can always pull the head if you have too. Good Luck!

I forgot to tell you. I have had a cam follower pop off. I put it back on and ran the car. If I were you, I would try to put it back on.

I've had the follower come off on more than one 2300. A sticky valve or lifter could be the problem. High reving and/or a worn camlobe is also a possiblity. Those 2300's seemed to wear cams. Roll your engine over and see if the valve and lifter is opening and closing properly. Check the cam lobe height and compare it to the other lobe heights. If you don't see any problems then put the follower back and you may get some more life out of the 2300. Am I on the right track guys?

Sounds liek the right track... I had an old fox Stang that I beat the crap out of.. It would spit out a follower every now and again.. I'd just chuck them back in there and they would stay put till I reved the crap outta it again..

A friend of mine had the same problem with a 2.2 mopar. A pain in the rear. It was popping them off regular and was cleaning the lifters each time. That got old quick so I mixed a batch of "lifter cleaner" up for it. 3/4 quart of kerosene and 1/4 quart of laquer (sp?) thinner. Dumped it in ran it for a few minutes, changed the oil, and it never did it again.

I DO NOT RECOMEND DOING THIS! I did it to make the turd last her a few more months until she could get another car.

You could look into the Ford Ranger camshaft with roller followers (late 90s and up 2.3L). That should give you some higher RPM stability. The cam and followers aren't that expensive either.

Good luck!

Yeah, I got a new cam about 2-3 wks ago, and have been searching for the cam seal, found one today at a place that specializes in GM parts (go figure) for 13 bucks (Finally found a Ford dealership that had the part too, but they said it take 3 days to get it in... should be putting it in tommorrow (finally! I'll get to drive it under it's own power!!!!!)
I also have to put on the new fuel pump and finish my carb rebuild but no biggie.... It'll be rollin' tomorrow!!! (how many times have I said that over the past three months???)

Okay, got timing belt/ belt cover off, got pulley off, got retaining plate from the back off, and went to compress the valve springs with my dad's brand-new valve spring compressor to discover it wouldn't fit!!! On the package in obscure writing it says "For GM V-8 engines" Oh well, does anybody else know how to get the followers out from under the cam??? (besides over-revving the engine, cause it ain' runnin at the moment)I did find a place that has a tool they say should fit, but, its $29.95 and I don't have the cash!

You could try a Pep Boys or NAPA, I think they have tool rentals (assuming your in the US) or Canadian Tire does (assuming your in Canada). Other than that, I'd think the tool is rather rare to find in someone's garage!
Goodluck!

Well, Got the cam, followers, and all but one of the lifters out... It's stuck!!! It's the first one (at the front of the engine) and when my dad tried to pry it out... It Broke!! I got the rest out while dad messed with that one, and all we have left is a really screwed up lifter... Got a tool that may help us get it out (gotta love Advance Auto Parts) and I will try tomorrow... Wish me luck!!!

Its been awhile but if memory serves me right the first mark, with regard to rotation, is 6-8 deg before TDC and the second mark is TDC.

Hope that helps
