not often at all. Maybe others will chime in, but you really dont need to change it, unless you pull off the snout.

People use S/C oil for the Pontiac Eatons... You can get it at the Pontiac dealer, it's cheaper than Ford. Same stuff

On the 99-03 L's the stock PCV valve is 2 way, and allows oil to be drawn up into the upper plenum (the hose right behind the IAC motor). A lot of people block off this hose and replace the PCV with the Cobra PCV valve (like myself).

 

Here are almost all of the parts numbers for the manifold up to the throttle body:

BOLTS -

Throttle Body
(4) ?
(2) N808429-S309

Plenum
(5) N808429-S309
(1) ?

Piece Left of Plenum

GASKETS -

Mid-Plate to Manifold

Gasket for Intercooler

So a stock PCV on say a 2000 Crown Vic (4.6 just like the GT) wouldn't cause this gunking to occur?

I'm using M1 5W-30, I heard synthetics mist more easily than dino????

 

Does Ford know about this problem about oil going where it shouldn't? and if it has been happing since the 99L's why haven't they fixed this problem? I have an 03L and after seeing this I feel really dissapointed, what should I do?


Please someone let me know what I should do...

Try a searching under "seperator".

NoSurprise

 

oil sep mod, or pcv from 03 cobra, one of the swanson pcv kits, or go like i do and use krankvents. some say the breather is supposed to help but i wouldnt try it

 

Nice Work

Could it be that this site is returning to its roots?
Where it was a great place to exchange info without BULLCHIT...........naw, it can't happen, or could it?

Once again, great write up, maybe everybody will get an idea and do something similar

 

How much $$$ did the gaskets run you???

 

I reused mine this time. Next time I'll be picking up new gaskets when I tear it down to have another look.

We'll see how good the PCV 'kit' works tonight when I run the HE// out of it at the track

 

part number for the GM supercharger oil is 12345982. Got it the other day at work.


I know i brought this post back from the dead but i had it saved because i plan on doing this after xmas.

 

Great post! I don't know how I missed this one.

 

Maybeeeeeeeee.......its because you where busy posting **** over on the JLO site
Now get back there and start posting more, for Leeann and Me

 

Ok ya busted me...I guess I better get back to 'work'

 

Which of the listed bolts are the torque to yield bolts that must be replaced?

Is this the ones:
Intercooler
(2) N606500-S100

Is there any other bolts that should be replaced?

Also from the guys that have done this, which gaskets need to be replaced??
I know you can reuse some of them but which ones get damaged to where they are questionable??

Thanks
Rob

 

The lower and upper gaskets to the intercooler are metal (read: some feel that metal gaskets dont need to be replaced; replace them if you want to). The gaskets for the upper plenum, throttle body, and EGR are all designed with fibers that crush so you should replace them. As far as torque to yield bolts, if they are the ones you torque and turn an additional 90 degrees, then the throttle body uses them. Also the upper plenum bolts may be TTY.

I just replaced the gaskets so here's the part numbers on those:

Lower intercooler: 1L3Z9462BA
Upper Intercooler: 1L3Z9H486BA
Upper intake plenum: XL3Z9L437CA
EGR: F6TZ9D476DA

I didn't need to replace this one but here it is anyway...

Throttle Body: F81Z9E936AA

I got my parts for half the price most dealerships are charging here Genuine Ford Parts

Good luck
