Is the valve cover gasket stuck to the valve cover with black RTV? If so rip that off, clean the valve cover gasket surface, get a new blue silicone gasket and install it dry. These gaskets do not need RTV and the fact that it is on there is suspect as hell to me.

It’s not, I just set it on the valve cover for the picture. The gasket easily came off and there was like very very little amount of gunk I had to scrape off the cover, the head surface was damn near perfectly clean.

I have the LMR metal gasket with o-ring to go back on. Will keep everything clean and dry.

Is there a torque spec for the cover bolts?

 

[AeroCoupe]

Just my .02 but the FelPro blue silicone gaskets are the best valve cover gaskets made. I’ve had the same ones on two motors and the covers off a lot and zero leaks. Others here have had similar results.

I believe Ford days 3-5 ft-lb but I just use a 1/4” ratchet and take them down snug (center two, corners on one end, and then corners on the other end) and then just bump them. The blue silicone gaskets have metal rings in them which set the compression.

I proceeded to clean out the injector holes like where the bottom o-ring would sit as they were pretty crummy. If by chance tiny bits of crud fell down into the injector holes… how bad is that? I was very careful, used like 100 qtips to get them as clean as I could, but I can’t guarantee some crud didn’t made its way down there.

Not bad at all. Maybe follow up each injector hole with some carb cleaner. That small/soft stuff will get vaporized on the first stroke.

Awesome. Thats a relief.

I dropped off the injectors at a local engine shop. $32/injector and they can fix the cracked pintle cap on the one. Not sure if its good, but they said they will get the injectors within 3% flow of each other.

They should be replacing all the o-rings, filter screens and pintle caps…$32 each??? Holy hell man that’s high. I paid $125 for all eight of mine to get done.

Ya i thought that was high too based on what i remember Nicholase saying he paid. BUT, i'll pay for convenience. The shop is close and i don't have time to research a bunch of other potential places. Plus, i'm sure i'm paying the CA tax as well.

They are doing all that you mentioned though.

 

[Noobz347]

Better be drinks and a titty show in the waiting room.

 

[gkomo]

I just assume everything and anything is 40% higher cost here in Cali for no reason.

Not justifying the cost, but knowing my injectors are all fresh and functioning properly for $250 is acceptable, for the piece of mind at least.

This is the place doing the work. I had never been there before, but it had a good ol' old school vibe.

 

[AeroCoupe]

Just another reason I will not live in a blue state. Absolutely beautiful place out there but pass on all that tax and getting into my business.

Looks to be a very reputable shop for sure. Price probably has to do with the higher labor rates. Guy that does mine is a retired nuclear engineer that has a shop at his house and he does high end mechanicing in.

Got the injectors back. Can't say i'm thrilled with the packaging, just tossed in a ziploc baggy.

They didn't provide me with flow data (like on paper), but they showed me a video of them flowing at different rates. At the end they all were super close in the volume tubes. I couldn't see what the measurement was (ml?) but they were all within a bar of each other.

Looks like all new o-rings, pintle caps and screens. They gave me back all the parts they replaced in their own baggy, i guess to show they have been replaced.

Sounds like a win except you said nothing about the lap dance.

Not sure i'd want a lap dance from the lady helping me.

Oh! You got a chick?


I got Dave. Had to wait for him to finish emptying the trash.

 

[gkomo]

Got the injectors back in and fuel rails tightened down. Put a little motor oil on the o-rings and they all slid in easily.



Tried removing my crossover air tube that goes behind the heads, but bolts were stuck so I sprayed them with penetrating oil and will try again another day.

Speaking of penetrating oil, I couldn’t get my throttle body separated from the studs, so I propped it the whole intake upright and sprayed penetrating oil to let it sit overnight.



Lastly I put two coats of clear on the valve cover. Not going for show car quality, just something better than it was.



I think I’m going to finish one side before I move onto the other side.

Watch out on the TB studs. If the coolant was leaking a little bit it seems to really wreak havoc on the studs.

I had the same problem a few yaers ago with my stock TB. It would not budge. I eventually got it off without damage.

What I did: Take two nuts and thread them on one of the TB studs. Take two wrenches and tighten them together. Then turn the nut that is closest to the intake. This will remove the stud. After removing the first stud I found a ton of corrosion between the stud and the inside of the TB. Do this for all four studs. Once you get all four studs out then tap the TB with a soft hammer.

The corrosion between the studs and the inside of the TB is why mine would not...

Good post, I may have to go that route. I bought a trick flow gasket and stud kit so I have all new studs to go back in.

So I got the drivers side valve cover loosely on with all the bolts. How can one be like 100% sure the gasket is seated correctly?

Don't over-torque it.
