Sea Foam, pcv valve, and maf sensor

[Ranger482]

Hi all,

I have a 98 explorer with a 4.0 sohc and gonna be doing a tune up soon(plugs, wires, etc.) and have a few questions

First, what is sea foam and how is it used? Does it really clean the motor as good as everyone says and is it easy to use? Where can it be bought?

Secondly, how often should the pcv valve be replaced? I havent done mine yet, and am at 147,000 miles.

Lastly, can the maf sensor be cleaned without damaging it and what should be used? I was thinking brake cleaner bit idk. any suggestions?

Thank you for your time.

I've never used it, but theres about 100 threads about it search the site using the little searchy thing.

i'd say 30000 or 40000 miles its cheap insurance

Its called electric parts cleaner, it will actualy say on the can safe for mafs, umm brake cleaner will actualy strip paint its rather nasty stuff id save it for your next brake job

Advance sells a cleaner made just for MAF sensors, its made by CRC. evaporates quickly and does a good job. How much it helped i cant be sure of.

Be extremely careful cleaning the MAF sensor. They are fragile. Check # 42 in my list of useful threads for more information.
