Exhaust Manifold Replacement

[gixer2000]

Gixer where are the Dorman manifolds made, just curious?

I'm not sure.. Fordtechmakuloco recommends them for the 3 gen so thats why I used it.

I just did mine last week.

I used PB Blaster.. Break the nut. then tighten, then loosen, then tighten about a 100 times til it turns free.
I am very patient, my arms and neck are killing me, but its better than a broke bolt or stud.

I'm thinkin you miscounted...lol Kroil came in dead last at #6

Well I'm impressed, guys for the best overall rust loosen up fluid, it's liquid wrench. Kroil comes in #4. And is $15.00 a can. The transmission fluid/acetone mixture is 2 nd place, but can be flamable, and tough on paint. Thanks Habbibie, great video.

Passanger side started leaking today, ordered FoMoCo replacement manifold kit.

It's not that bad but getting that top starter bolt blows. Make sure you have a couple 2' extensions and a swivel to make that bolt easier.

Not looking forward to this one......I’m going to wait for the spring weather to break. FordTechMakuloco (Brian) said it won’t harm anything to run it with a leak esp with the multi layer gasket since it seals itself back up in the short term as it heats up. Original manifolds lasted over 170k miles. Leaks for about 20-30 seconds and seals up.

I ordered both the OEM Ford drivers and passenger side manifold kits. It was an Ouch but I’m not doing this twice, will be on a nice spring weekend day.

Anyone know why ford added heat shields to the replacement manifolds? My originals don’t have them but the new ones on order do.

Steve, I recommend watching "project farm" channel on YouTube, he does a pretty comprehensive comparison of all the penetration oils head to head and has two videos regarding this subject... you'll be surprised of the results cause we old timers keep thinking Kroil is best... which as it seems with today's technology that it's not as we claim it to be...

I like this guy and is videos and I hate youtube videos....but I can't say I have seen anything near these results.
I have never seen liquid wrench work as well as PB blaster and there is no way wd40 is even close to as good as PB and no way better.

I've been using all three for over 40 years. I just haven't seen similar results.
