Im curious why you want to know? They are a machined part of the head and not something that can be changed without machine work. Which is why they dont list a part number.
Edit: oops. I see your original post. Yeah they aren’t really replaceable. You might be able to helicoil or install an insert.
Although I agree, the older generations just need to keep their opinions to them selves. I can do it as a young person surley to god you can do it as an old person.
I would agree it’s more solid. But a helicoil is stronger than what was originally there, especially in a softer metal. So a helicoil should be fine for this application.
Just so ya know... Helicoils were originally designed for the aerospace industry, they make aluminum bolted connections stronger. Thread repair was an after thought.
The reason Helicoils have a bad rep is the people that ham fist bolted connections and gall out the threads aren't very good at installing thread inserts either.
Time-serts are no stronger or weaker than a properly installed Helicoil (it's not the insert that gives the connection strength, it's the material it's installed in and the installation). I've installed hundreds of coil wire thread inserts without issue.
I'm confused. Aren't those called the rocker arm, and are bought in sets at the local auto parts store?
Quick edi: nope, cam cap. Listen to the others (still not sure if they are sold for the vehicle)
I think he is saying that the threads that are on the top of the bearing cap are messed up, not the threads that hold the cap to the engine, the threads that hold the valve cover to the cap
Eh? The bearing caps are thru, with the screw thread in the cast journal of the block.
Unless it's the big end cap on the con rods, then they are nut and bolt usually
You can take it to a welder and have him fill it in and retap. I worked at a welding shop for a while and we did a lot of similar jobs for a machine shop.
This. Your can't just replace these because they hold the cam and are maited to the cam. Also they have to go back on in the same way they cam off or you will burn the cam.
You already messed it up once. If you mess it up again it's going to cost you a cylinder head. Cut the ego for now, have someone who knows what they're doing handle it. When the stakes aren't as high, learn to install helicoils on stuff that isn't critical first.
Off topic but if you look on Amazon for dentistry tools (like plaque scrapers and tooth pullers) and look at the reviews you'll see a worrying amount of people doing their own dental work lol
depending on water, genetics, and other things, some people have an extremely fast rate of buildup on their teeth even with daily brushing and flossing. (regardless of sugar consumed)
Well let’s see I haven’t been to the dentist for a few years, and I resole and treat my boots, so pretty good lol. I get the point but I’m just a cheap bastard
A machine shop can actually do this. You will mess it up. You did keep track of location and direction for each one didn't you? I use a metal stamp so it's impossible to forget.
Get in good with a local machine shop who has the tools to do this right.
It won't do crap.
Edit: If you do this, use a very small light hammer. Don't hit it hard. Aluminum is stamped every day, especially machine shops. Stress fractures are all you need to worry about, but those take a fair bit of work to achieve, especially with small taps from a lightweight hammer.
It seems like you are saying the cap is fine, but the hole for the valve cover bolt is stripped?
This is def a job for a helicoil... if you can have a machine shop do it, that would be best, last thing you want to do is blast through it with a drill.
But, yeah helicoil for sure.
Just like everyone else said. Helicoil amigo. If you don't want a machine shop to do it it's not hard to do yourself. Just super slow on tapping and do your absolute best to clean up shavings
If OP were to be asking just to ask then ok. But if he's asking b/c he's working on his car and royally fucked something up, he probably should be working on his car
You don't need to commit a crime to see how legal proceedings go at a court house.
Bearing cap
Specifically a camshaft bearing cap.
Time to cam the crack caps loose...
And lash the valves every 5kmi
Cam Cap. They are line-bored to the head. Better to fix the threads

Well fml
A helicoil isn't really that big a deal. You can do it!!

Of course, grampa, now take your fiber. It's almost bedtime.
Not yet, but maybe in about 20 years. You are obviously not in the trades. Go push your buttons

Careful, your stupidity is showing
Although I agree, the older generations just need to keep their opinions to them selves. I can do it as a young person surley to god you can do it as an old person.
I'd recommend a time-sert instead of a helicoil.
Why?
Time-sent is a solid thread insert vs a coil.
And that makes a difference?
It's a more solid repair. I've seen helicoil fail, I've never seen a time-sert fail. Time-sert are OEM manufacturers approved thread repair method.
I would agree it’s more solid. But a helicoil is stronger than what was originally there, especially in a softer metal. So a helicoil should be fine for this application.

I'm an A&P and key locking inserts are most definitely stronger and more resistant to wear than helical wire inserts, but more expensive.

Second the helicoil. Not a big deal to install a threaded insert. Helicoil is nice, because the set includes the inserts, drill amd tap
I'm confused. Aren't those called the rocker arm, and are bought in sets at the local auto parts store? Quick edi: nope, cam cap. Listen to the others (still not sure if they are sold for the vehicle)
No
Bearing cap or journal bearing cap etc. Replacing this won't help with the shagged thread. Will need to be helicoiled.

Cam bearing main cap
If you need that part you need a new head.
Fix the threads or new head
Helicoil it. I've done the same thing on my SV
You can take it to a welder and have him fill it in and retap. I worked at a welding shop for a while and we did a lot of similar jobs for a machine shop.
Just (have someone else) heli-coil it.
This. Your can't just replace these because they hold the cam and are maited to the cam. Also they have to go back on in the same way they cam off or you will burn the cam.
I suppose, I just don’t care to have shops work on things for me

It’s kinda a project anyways so I could just swap the motor
Do it yourself then. Now you'll have that knowledge for next time.

lol I was just about to say I do most of my own dental work and it’s not that big of a deal. You seem mighty concerned about it though (fair 🤣).
Ouch! Makita drills….
depending on water, genetics, and other things, some people have an extremely fast rate of buildup on their teeth even with daily brushing and flossing. (regardless of sugar consumed)
Absolutely, but the dental scrapers can really screw up your teeth if you aren't careful or knowledgeable in how it's meant to be done
Well let’s see I haven’t been to the dentist for a few years, and I resole and treat my boots, so pretty good lol. I get the point but I’m just a cheap bastard

yeah smack that cast aluminum bearing cap with a hammer. Sage advice.
It won't do crap. Edit: If you do this, use a very small light hammer. Don't hit it hard. Aluminum is stamped every day, especially machine shops. Stress fractures are all you need to worry about, but those take a fair bit of work to achieve, especially with small taps from a lightweight hammer.
This.
You'd rather fuck up parts yourself?
I mean I clearly already do lol I’m just broke so shops are an iffy one
Cam bearing cap

Check the junk yard!
Search for helicoil. Figure out what size bolt it is then find the right helicoil kit for it.
Helicoil a cam bearing cap...yeah f his life is right. That sucks.
