Seafoaming the Top End

[byrds6]

I am wanting to Seafoam the top end of the engine. However I no matter how much searching I have done across the internet I can not find the best place to put it in at. Almost everywhere I have read has said the brake line. This isnt the best place as it only gets to the back two cylinders. Does anyone have another suggestion? On my old Camaro there was a hole in the throttle body blade you can spray it in through. There isn't one on the Tahoe like that though. Suggestions would be appreciated. Thanks.

PCV port on TB.

I dont think there is one. I think the PCV port is in the center of top of the intake. Ive had the throttle body off and the only thing I had to disconnect from it was the wires that control it.

top center port sounds like a good central location... eeh?

I guess that depends lol. How much suction is there through the PCV system? I didnt think it was that much.

Same amount thats pulled through brake line....
Hence why its such a dirty circut and requires a catch can to keep oil out of intake.

OK I guess Ill try in that way. I didnt know the PCV system had as much vacuum as the brake lol.

Why wouldn't it? the vacuum supply is coming from same source..

Ahh I didn't know that rofl. I am by far not a mechanic. I know enough to get in trouble.

well, be careful with that seafoam. dont hydrolock your engine.
