I am in the process of swapping engines out and during this i removed the lower intake on my original with 52K on it. Daymn--its a wonder the ports were opening at all. talk about dirty--carbon and such was everywhere. It will take me a fw hrs to get it clean the way i want it. Anyone else done this?

I pulled mine at 60K miles...and it was barely dirty at all....it all wiped off.....

No hard carbon at all.

I pulled a friends 4port UIM and unblocked his SSV..and it was crapped up good....

I tracked the hell out of mine...with pre-mix (and Lucas UCL occasionally) and did a "seafoam" type treatment at about 50K miles.....

Maybe thats why it was so clean??

 

I'll drink to that.

 

It might've been oil blowback and got caked onto the intake.

 

there are some photos of mine out there at 55k miles. they were gunky, but not carboned..


lets see some photos!!!!!

beers

 

pics or it didn't happen

 

I read these threads and get scared. I demand everyone stop.

 

read my history of posting pictures---i am computer challeged--besides i have already cleaned it. It just surprised me. I have used bk 44--not a heavy tracker only about 3-4 times a year---probably need to go more.

dragger: why are you swapping engines?

 

Did it look like the one in this thread?

So when I have my Header installed can I have them clean mine?

 

Dam it. Guess I'll have to stick to 1st 2nd 3rd wot! lol

 

hmm .... I got my Greddy catch Can for like 2-3 months already ...

maybe its a good time to install them, stop being so lazy ... *slap myself in the head*

 

In my defense the car was barely driven for a year!

 

no need to admit it so fast

 

What's the worst thing to admit too...the crapped up intake...or being my friend

Go to bed..............

 

Those pics look exactly like what i saw on mine.Blow by gases, i guess is what is causing it. i agree with others on that. Maybe my new water meth system will help and for certain a catch can will be added now.
I bet a lot of cars are running around with this.
maybe we need to start "steam cleaning" this engines some?

in response to why I am replacing engines---getting low on compression and the wife wasnt looking!
also needed a core to build the way i want it.

OD am I crazy or didn't you Pettit SC your car a couple months ago
Now this? Did it blow up? I finished w/the Pettit thread...maybe missed it...

 

I was wondering the same thing.

Mostly the Crapped up intake you being my friend is a god send because
1. Repairs Cost are paid in Liquor
2. I can now drink my car problems away with someone
3. You like fixing my car and listening to my hilarious voice mails :D

 

i installed pettit in November---i need another engine to play with.
OD

 

I don't see how since the large majority of the intake manifold only sees incoming air. Only the very last portion may see hatever comes out the injectors and most of that goes into the chamber without touching the intake.



I would thinks it's more a seal/compression issue with crap blowing back into the intake, which is why he has it out ...

 

agreed team--thats the only thing it could be.
OD

 

Problem with that is my engine had very poor compression..and vac.

That's why I pulled it in the first place....I really don't know. I also had a recurring problem with oil i the intake that I put down to blow-by as well

So why do some engines get crapped up and others not??

I really think its driving habits....
