3 Valve spring Swap

[US-1]

where can I find a rod coupler? Home depot doesn't have any

Hardware store. Piss on Home Despots.

Piss on Home Despots.

I second that motion. Plenty of space but never what I need.

ok I'll be heading over to ACE hardware as soon as I have my coffee. Any tips to getting the exhaust spring in and out? I find these more difficult due to their position. I'm going to buy that threaded rod, hopefully with that it doesn't now hit the shock tower or something.

I found the exhaust springs to be more difficult also, especially for the rear cyls., just be patient and don't rush things.

if it's a renatal tool then use a thin peice of plastic to raise it up.

I did the same thing.........cept I used a wrench. Agreed, the tool could have been designed much better.

I just finished the spring swap on the passenger side now I'll begin the passenger side, there seems to be more room so we'll see how this goes.

Can anyone help me once again? I'm getting these codes:

P0345- Cam position sensor
P0349 - Cam position sensor
P151A - unknown

I've read on here that sometimes the battery/alt causes the first two CEL's but I've havent seen anything for the last one? Does anyone have this solution after a cam install/valve spring swap? I'm going to change the oil filter in case debis is in there, would I be able to just unscrew the oil filter and slap on the new one without oil spilling out? I mean all the oil? I know a little should leak but will it all? I'm just asking because I just changed my oil a few week ago and I'd hate to waste my synthetic oil.

Car seems to run fine with the email tune too. but I don't know if the CEL is hurting the performance or not.

If it wasn't throwing those codes before the cam swap, I would say that your timing may be slightly off. How did you do the timing?

 

[shikwann]

I originally had mutha thumprs installed with no CEL, when I removed them and put in the stock cams, that's when I got the cam position CELs but not the third code. I never removed the cam sprockets from the timing chains so I'm sure they should be where they were originally. When I installed the v. springs and the new cams that's when I got the same codes plus the last one noted above.

Hmm... well as far as the p151a code goes, it's for the CMCV's. So I would check all the wiring for it. I uploaded the TSB on it.

I still have a feeling that the timing may be slightlty off... Even though the chains never came off the sprockets, there is still a possibility that the chains lost enough tension on the crank sprocket to move a tooth or so. But if you are certain that it's not the timing, I would check to make sure your alternator and cam sensors are working properly. Also check to make sure that the phaser isn't damaged. IMO though I would pull the front cover and ensure the timing is correct. Hope this helps man and if you have any questions just let me know. I've been down this road before with my stang, heh. You'll get this all worked out soon enough.

How would I check if the phasers are in good order or not? You mentioned to scope out the alt n cam sensors, how do I troubleshoot that?

As far as the CMCV plates go, I have delete plates. Could the tuner possibly forgot to compensate for the delete plates in my tune?

The phasers can be checked by pulling them off the cams... (before doing so check for any ticking/clacking type noises through the valve cover were the phaser would be, if apparent then it is most likely not working correctly) On my phasers, two of the three little pins that hold the timing sprocket onto the actual gear were broken, so I would check those. Other than that there is not much more that could go bad on those from what I've heard. Also check to ensure that the timing sprocket on the phaser isn't bent or damaged in any way.

The cam sensors I checked by swapping them with a buddy. If it still throws the same codes with different sensors then you know your problem is elsewhere.

I can't help you out with the alternator... I'm sure it can be checked, but I'm not too electrically savy. I would start by taking it to an auto parts store to have them see if its in good working order... though, there may be some problems that may not show up during their testing. Maybe someone else can give you some more insight on testing the alternator.

I doubt it will be your alternator or cam sensors though because the codes started after your swapped the stock cams back in, so I'm guessing it will either be your timing or phasers, more so the timing.

If you have delete plates, then yes it sounds like the tuner forgot to update your tune. I would make sure and fix that first (updated tune for current mods), then reset the codes and see what happens.

 

[shikwann]

Man, I hope those phasers aren't screwed. Are the cams supposed to become a little noisier than stock? I'll see if I can find someone local who'd let me swap out the sensors to test them out.
