Project: "Rigor Mortis"

[Pookapotamus]

I was looking at the 3rd gen, I think, did not get much time to research.

The last time I looked at these, it was pretty promising. They are supposed to run just about anything and you wire up as much of it as you need. Not sure yet if they will run variable valve timing on a dual overhead cam, but I hope so. Got my eye on a future project

[Pookapotamus]

yup ms3 pro, will run everything from a blender to an airbus a380...well almost!

pook wants one bad!!!!

screw the jet chip!!!

[4.3LXJ]

I knew you would say that. That is worth about 20 jet chips and so much more flexible.

Yeah the MS Pro is a very nice unit.. Got a few friends that run that setup in their "race" cars.. from drifting to a few drag cars... from 4 cyl N/A, to 4cyl turbo charged.. to monster V8 (that I'd love to steal to swap out with the 5.7L Hemi in my Ram... and the 5.7 would have a nice rumble for under the hood of the XJ!! LOL

ok so i was fortunate enough to have a stock 4.0L find its way into my shop, so i tore it down and did a quick degree on the cam just to see what they have stock. I got 19 ATDC that the intake opens .050.

now i need to find out what the stock cam is supposed to be then i know if i am degreeing properly.

[Pookapotamus]

I am convinced that I have not degreed the cam correctly, but I can't figure out where I went wrong, watched a ton of vids on the net, sure looks like I am doing it correctly, but they why do I get wrong data on a stock 4.0l?

so far the only difference I can see is v8 to I6, but it should still be the same procedure.


Pook Confused!!!

I just cant prove that i'm wrong!!!

[4.3LXJ]

It should be the same procedure. However before you tear it down again, remember the code can be caused by a bad cam position sensor. If you had an OBDII, you would have a random misfire for a particular cylinder, or random cylinders. My suggestion is that you owe it to yourself to change that out. If you are getting a backfire, it means unburned gas is going down the tail pipe. That to me indicates no spark even if you don't have a cat

[Pookapotamus]

Don't have any codes anymore Steve, I am just looking at the cam timing again to see if it is set wrong.

[4.3LXJ]

I understand, but still you have to take into account that there is a misfire to get a back fire.

[Pookapotamus]

That's what makes me thing the cam timing is too far advanced.

Did that bearing work for you??
