since I last posted, I've replaced the headgasket, dont ask! and installed a venom highflow cat and have a brand new J3 chip with a stock ED XR6 pre-program.
after the head gasket went on im having this blogging down and sometimes stalling issue! I have to roll the throttle on really slowly to try and avoid bogging, both stand still and drivingI also tried using the J3 chip, but exhuast started blowing black smoke and really rough idle so i think i'll have to wait to get that tuned on the dyno. looking back at my dyno sheet, 164.4rwhp (122rwkw) seems abit ordinary for the mods i have done, in my opinion anyway. what do you guys think? |

How does it go with the j3 removed ?
If it was fine before the head change then problems accured after the head change you have done something wrong possibly, check the hose to your Map sensor hasn't fallen off,

I haven't gotten the J3 to run yet, fuel pump just keeps making its whirling noise, I'm gussing the ecu port still has alittle bit of s**t on it, this issue is unrelated to the J3, as fair as i can see the map sensor is still on, what is the likely hood of the the sensor crappin it's self?

Check the hose coming off the manifold that goes to the map sensor, check all vacuum hoses that are connected to the manifold , it's possible the map senor could be stuffed

all the vacuum hoses look like there on ok, I just pulled the map sensor hose off while the car was idling and it dropped in revs and run real rough!

Yeah it'll do that lol.
Backtrack what u did when u changed the head cos something ain't Right, it valves could be stuffed, or Ur engine , that would explain why your not making as much power as u should , or could be the dyno operator

the head is making fairly loud ticking noise, since the regrind cam went in, so i assume the extra shims never actually went in, but it seemed fine before the head gasket was replaced. I knew I needed stronger springs, but I shouldn't have stuffed the valves yet...

That would be the lifters ticking , once they pump up with oil they will quiet down, unless the shim went in the wrong way then they won't get any oil. How long they been noisy for?
U might need new ones, but id be finding out if the shim was in the right way, On one side of the shim there will be a straight line marked on it, The other side will be 3 markings like a triangle , now when u look down the little hole on top of the lifter u should see the straight line ,the triangle side should be facing down, now I'm not 100% sure so don't quote me lol But I think that's how they go,

I have no idea about the shims, I got the head a big port n polish and valve work, I told the shop It would be used with a regrind cam, which I supplied the spec of the cam, and they told me they would put in extra shims to suit.... its been loud since I put the head and cam on the engine just before Christmas.

ok. I've called the port n polish joint and had a chat to the manager, and it looks like he added a extra shim to each valve spring to raise the spring pressure! so that means theres no extra shims in the rocker assembly! could there be damage to the valve by now? having the extra shim in the spring would it necessary to get crow spring anymore? and can I get these rocker shims from a hardware(just normal washers)

If you can, pop into a pick-a-part or something similar and pull them out of the rocker assembly...if you want to be nice tell them you are grabbing these, if the guy doesn't know what it is you might get it for free...if not just throw them in your tool box. Better yet, get a whole spare rocker assembly if you can get it for cheap at a DIY yard. I got mine for under $30 with spare shims and lifters. Go to Ford if you want new...hardware/nuts/bolts stores won't sell the right one.
