WTF?!?!

[oilywater]

Okay so my buddy has a 94 Mazda b4000 and apparently it was lacking in power and it was blowing lots of white smoke he asked me if I would do a head gasket replacement for him I said sure he got the felpro gasket kit all the good gaskets like manifold intake head valve cover etc and I went ahead and replaced one the intake gaskets we're a little bit different than the stock gasket or what I thought was a stock gasket there was no valley cover attached to the gaskets to either side so I double checked apparently it's cosmetic so I went ahead and use the felpro silicone slapped it all back together gave it an oil change let it drain for I don't know 15 minutes or so plug the whole back up change the filter put new oil in it fired it up and still smokes like a banshee I ran the idea past them that the head could be warped is this a real thing like does it sound like it could probably be a warped head help can't figure it out!!!!!

Heads warping is absolutely a thing.

Did you have the heads checked out... cracks and flatness?

Does the cooling system build pressure quickly?

Ate you saying you're still getting water in the oil?

 

[oilywater]

Nope this was an in front of the house next to the street in 85° weather in the direct sun type job....

Water in the oil most definitely infact it seems as though there may be more water then before

As for pressure I didn't notice to be honest

So these heads are cast iron not aluminum I mean how much would it take to really work them?

And finally my last question for the panel is do you think that using the Blue devil water glass sealer would be worth running through the motor what are the pros and cons of this??

Before I would do or decide anything more, I would take the heads to a machine shop to check their condition. From there, you can think about what kind of repair is needed. If the heads are warped, it might be as simple as getting the heads machined so they are flat again but it depends on how bad they are.

If the heads are cracked, then you gotta decided if a repair is better, sourcing some new to you heads, or new heads are the way to go.

I'm not a fan of any of the quick fix solutions out there. They tend to cause more problems.

the intake gaskets we're a little bit different than the stock gasket or what I thought was a stock gasket there was no valley cover attached to the gaskets to either side so I double checked apparently it's cosmetic

Early 4.0L that's good to know, more later...

Yes, that centers action is cosmetic. Most gasket makers switched away from the one piece gaskets a long time ago. IIRC they used to include a note about that with the gasket set. With a one piece gasket there are potential issues with fitment if the block or head surfaces need to be machined. With the separated gasket, one size fits all.

BTDT, it sucks.Sounds like you're a good friend to have.

Was going to ask if you changed the oil, then reread the first post.

The early 4.0L and Cologne V6 heads were prone to cracking and warping. Being a 94 and one piece gasket, it most likely has stock heads that fall into that category. Ford improved the design in later years to correct this. The aftermarket has made even more improvements. IMO not worth investing in stock heads, get aftermarket castings for the improvements. Best to stay with 90-94 style, later changed chamber size causing higher compression. Not bad for power, but needs higher octane fuel, and may not play well with the computer.

And finally my last question for the panel is do you think that using the Blue devil water glass sealer would be worth running through the motor what are the pros and cons of this??

Don't. Just don't. Probably wouldn't work anyway, and just contaminates the block.

Other thoughts...

Did you use new head bolts?

It's also possible for an intake leak to cause these problems.

Yeah, on Ford's the heads like to crack between the valves and it just pushes coolant into the exhaust, it's a thing, I've had that problem on one of the Explorers I had...
