I was putting a throttle body spacer in my 1994 F150 it has a 5.0 liter with 290 000 km. The throat and the butterfly's in the throttle body were coverd in black sludge also the inside of the intake. The gasket between the intake and throttle body was leaking between the 2 throats. I cleaned what I could of the black sludge with brake cleaner and installed the spacer and K@N cold air intake. What can I use to clean the rest of the inside of the intake that I could not get to? Also would this gasket leaking cause this mess inside my motor?

 

you used brake cleaner bad idea.

 

yes, it worked fine I sprayed it on wiped it off and the balck sludge came off with some elbow grease.

 

i would be checking for a bad PCV

 

I played with small block chevy's alot more than My 5.0 liter I also had a 4.9liter 6 clinder and have yet to see anything likes this, Tar or Sludge A bad PCV will makes this kind of a mess? Are they Cheap like the old school PCV

 

I think mine was around $4

 

Have you been using a K&N air filter? I have read they can cause quite a mess.

 

I had the K@N drop in air filter for a year, it did make a difference but not like the K@N FIPK and throttle body spacer, guys what a difference I was told that this is all you can do to these to these trucks to chrank them up other than cams and heads is this true? I was wondering if some carb cleaner would work on the sludge if I spray it in the throttle body when the truck is running?

 

The ONLY thing you are supposed to use is "coating safe" T/B cleaner. The T/B and intake manifold have a coating on them which makes the EGR crud more easily removed. By using brake cleaner, you have at least damaged, if not totally destroyed, the coating.

 

did you feel a performance after cleaning the tb?

 

I installed u/d pulleyy and man what a difference those made. I'm looking at a MAF conversion, tb space, and a k&n next. Underdrive pulleys are great but bad news for your tires Yeah I second the don't use carb cleaner, during my senior year in highschool my auto shop teacher almost shot a kid for doing that lol.

 

Don't waste your money on a T/B spacer. From a performance standpoint, they make great paperweights.

The MAF conversion is only necessary if you're adding a cam and substantially bigger heads, and maybe not even then. I would bet you could sneak a set of mild heads like GT-40s and a Crane 2020 cam past the S/D processor and have it work just fine.

 

i would do it mostley for the gas milage, from what I've read it makes a 3-5 mpg difference on account of it's sfi instead of bank at a time, but I'd hate to hijack this fourm so i guess i'll start another if I get really serious about it

 

The spacer and the new K@N intake were awesome you would not beleave the difference in power and the way the tranny shiftes better I guess this is because of the motor working so much better that the transmison works better also.
I would highly recomend to have this done.

 

I would get your self a can of seafoam ' this stuff really works iv done it on my f150 ' its idle is like the day it came outta the shop' my truck has over 280 k on it and runs great. Heres acouple links to ppl using the stuff .http://www.youtube.com/results?search_query=seafoam+http://www.seafoamsales.com/motorTuneUpConsumer.htm
