And, so it begins, head gasket for our FZJ80...

[Mtbcoach]

Progress made, rubber band helped get the job done. Injectors out, putting on a box and shipping today to get them properly cleaned...

Injectors 1-6 with corresponding plug...

Intake manifold next up...

Johnny came by, brought Martin to help out, got the head off and all looks good. Very surprised as to how light the head is as compared to a 2F head. No need for any hoist, Johnny and I were able to get it out of the engine bay, he carried it to the bench without pulling a hamstring.

There is something about a well designed machine that gets me excited...

Head valves and chamber, all look much the same, nothing alarming...

Cylinders 1-6...

Now to get the head to the machine shop and start cleaning up all the parts to be ready for the reverse, re-installing all this stuff...

Jerry, on the throttle body - consider using a filter in a tee on the PCV hose. If you're not doing rings etc, it really helps keep oil out of TB. I used some filter from Lowe's for an air compressor and would have to empty it around every 5k oil change.

Thanks for sharing the tear down Jerry. This is great stuff, keep it coming!

Thanks for the feedback Joe, I'd planned to do something like that, going thru the various other threads on the subject.

I'll try to get better pics of the cylinders, can still see the cross-hatching on all the walls, really does look good. I feel good about buttoning it up and getting another 150k out of the engine...

 

[Mtbcoach]

Some better/tighter pics of the cylinder walls 2-5, tops of 1 & 6. I've not turned the crank yet, still cleaning up things taken off before I work on removing the carbon on the pistons and block deck...

Piston 1...

Piston 6...

Cylinder walls 2-5...

I'll be spending the next few days staring into the sand blast cabinet, getting everything cleaned and prepped to bolt back on once the head work is done.

 

[little_joe]

Dang what a testament to the 1FZ-FE - those cylinder walls look beautiful!

 

[Mtbcoach]

Spending time staring into the sand blast cabinet, getting things cleaned up while I wait for the head work to get done. Guess which one is next to go into the cabinet...

Those manifolds are looking nice! If you are interested, there is always the Jet Hot coating process to protect these things and keep 'em looking nice. I did this on the Mustang's headers and my Dad did it on his Mustang's stock exhaust manifolds too, the stuff is awesome: http://www.jet-hot.com. I think the process is heat rated well past 1000 degrees and it's some kind of ceramic...somebody else may know more than I about it.

Of course, now that I think about it, the manifolds are completely covered by heat shields, so I guess it may just be a "peace of mind" kind of thing.

More things to spend money on.

Jerry, just to warn you, the hi-temp power coating you did on the exhaust for the 2FE is already breaking down. Not to discourage you, just to give you info for your decision on coating those bad boys.

 

[Mtbcoach]

Thanks for the head's up Ramon. Do you think it's from heat, the product can't handle? Or, improper application? Hate to hear it's breaking down already, sorry...

 

[GLTHFJ60]

Ceramic coating is probably the ideal process for protecting the manifolds. Jet-Hot I've read is real good, but for a local guy, Carolina Ceramic Coatings did my old 2F valve cover and headers, and they came out great:

Don't mistake the info for me looking for an apology! I think it's the product. It's breaking down, not peeling. Just thought you may want to go a different route. I'll try and post a pic when I have 5 seconds to breathe.

Agreed, local is better in this case. I guess there are more options for doing high-temp coatings here in stock car country...I wish I had that when I was in VA.

I realized after I posted it might come across wrong...I'm apologizing for trusting a product and passing it on to you. I should have done more research at the time. The one thing I've learned about doing my own powder coating is it's all in the prep work, and, you inspired more research (as you intended) and found others not happy with the performance of the Eastwood hi-temp powder coating. Now I'm bummed with a 5lb tub on the shelf. Quick searches of my usual sites doesn't give much positive feedback for any high temp powder coating used on exhausts. One made by Dupont is the only one I saw with consistent positive feedback. I still might give this stuff a try on the heat shields and intake parts that don't get so hot.

Thanks for the ceramic coating referrals, something I might consider.

Yet, seeing them naked and clean makes me want to keep them that way also. I've got to find a way to get deeper inside than the blaster reaches, off to wander the tool isle for a honing tool with a flexible shaft, prefer to not use toxic solutions to disolve the carbon build up away...

You can do a clear ceramic coating on the headers

Beat me to it!

Gave the manifolds some love today with a die grinder w/3" extension and a butt load of "sandpaper on a stick" rolls. I was able to reach 95% of the inside tubing, trying to eliminate as much of the carbon build up as I could. Is it really going to matter? I think so, just knowing how much build up there was and leaving it in place would stress me out. So...invested the time to clear out as much as I could reach. Glad I did...

[GarnerFJ40]

Looks good Jerry, my top end looks about the same, a little darker on the varnishing on mine. May switch to a synthetic on the next change... Throttle body looks about the same on the carbon build up. I'll try the PCV filter that Joe talked about. Maybe it'll smooth things out a little...

Here you go Jerry...the quick way.

I'm sure the aluminum will be fine with this method.
