valve stem fell...keeper question

[HommerSimpson]

Getting the keepers back on is a BITCH! I haven't been able to get any back on.

Myself i just use one of them pocket flat head screwdrivers.. one with magnet on one end.. put a dab of greass on the flat end.. it woulld hold keeper of a short time... long enough to slip in ... and if you drop .. you got magnet on other end...or you can just wrap a wire around the screw driver and magnitise it a little.. be enough to hold it but also let loose easy... greas is my preferd way tho...

IJ, since you take the cams off to do the valve guide seals, none of the valves would be open in the first place, unless, for some reason, you were doing it one cam at a time. Why you'd do that, IDK. Kotu, I've seen a post somewhere about using a piece of paper to put the keepers in, but I can't remember where I saw it. I'll show you how on Saturday.

I suppose thats a possibility. My friend just did his 240sx, KA engine, and he just let the valve sit on the piston. 7M might not be so friendly.

The KA is an interference engine, The 7M is non interference thus there is alot more space between the valve and the piston which could lead to the valve falling through.

He turns the engine to bring up the piston in the cylinder which valves he is working on. otherwise you would need like a mile of rope to fill the cylinders with the pistons that are not at TDC.

But he said, you needed to put it at TDC to be sure all the valves were closed. That's the point I was talking about.

It would still sit on the piston, it must come down to fractions of an inch. If not, why not? Should still be able to grab the valve stem.

I think he meant not to be sure that all the valves were to be closed but rather when the valves are closed, indicating TDC compression stroke, not TDC exhaust stroke.

Right, it wouldnt fall through, but it would sit a lot further down making it alot harder to put the keeper back on while compressing the spring.

That would be me.

I need to start offering a proper tool rental service before some of you scratch up some bores. :3d_frown:

KA is a Interfearence motor.

M/JZ Motors or any toyota motor with a timing belt is far from it.

(You do the math.)

Rope is better than air because if you spit a valve seat you'll want to cry.

Now, can everyone stop guessing? lol

Seriously you are a moderator on this??? I would certainly expect more professionalism about this.... I am surprised that this thread has not been closed down, or has been limited on the middle school talk here. Personally this has went too far to keep Supramania as a informative forum about all of passion.. “Supras “I.J. Please do not give in this childish garbilygooop. Keep your composure here.

Take this for what it is worth. When you own a Supra expect to spend some coin. It’s like this... You do not half ass bathe yourself, you do not half ass pay your bills, you do not half ass have sex, you do not half ass do your job to support yourself / family??? The same follows with repairing you Supra... Do the tasks; being your “possible dropped valve” right the first time and she will thank you in the long run. Save some coin up and do it right/Pull the head off, do not skimp unless you are thinking short term engine life. If you plan on this being you Daily Ride, at least replace your head gasket with an O.E.M Toyota head gasket, and torque the original head bolts down to 77ftlbs following the replacement 2nd manifold gasket. I can honestly see the head being taken off without removing the 2nd manifold. Take your time, and think your situation through start - finish, and you will get it done. I have not done a in frame rebuild before on a MA70 with a 7M-GTE, though under the belt: 3 FLD120 with a C-13, and 1 Pete 379 with a C-15 blue printed on paper in frame rebuild. This taken under consideration to pass the class, from a instructor with a Army background requiring a 95+ to pass the semester. Trust me when I say think your situation through. Please follow your own intuition through, unless you are thinking " duck tape " then you have a issue. On the video to be proposed about using fishing line sound like a cool idea that may work.. Who cares about whether this works. Again do not half ass your work.. That is your name, and your safety as well as others on the road on the line, and you will have to answer to all of your work and repairs on the long short / long term aspect. Please stop the kindergarten babble and give the OP some legit info.. Do it right pull the head and repair what is in need. If you need a ride to work or what not there are friends if they are friends, or public transportation that is in your favor. I am not trying to pass off as a tool, just tired of looking at a post that is uninformative, and is going nowhere. Hope this helps the OP realize that Supras are not cheap, nor is staying alive, in all aspects. :cry:

^ Let's see. A person decides to do his valve guide seals, and unfortunately makes a mistake, dropping a valve into the cylinder. He had no intention of doing a head gasket, or any major work, just the seals. In your world, there's only one option to fix it. A costly and time consuming option. In my world, there are 2 options, the already mentioned costly one, or one that will take about 15 minutes, and cost 10 dollars at most, and maybe nothing at all. Why don't you wait till Saturday, when the video gets posted, to decide if this is informative or not. Learning cannot take place, if the mind is closed.

Jeff, with the cams off, all the valves are closed. Think about what you're saying.

It's not like he said, hey my drivers side miror fell off and we told him to duct tape it on. He said he lost his valve and asked if he had any ideas on how to retrieve it. No one mentioned duct tape at all, so I guess we should follow our intuition according to you. I don't se how we are half assing our work if we get the valve back in faster than pulling the head without any damage done. Finally were having a discussion, isn't that what forums are for? If you only want one answer for everything, go read the TSRM instead. I dont know why your so angry about this...o wait...i think i do, turn around....aha, just as i suspected, you have a stick up your ass. remove it and you will be just fine.

Right right, Ian was talking pushrods and i was trying to make sense of it.

 

[IJ.]

Before it goes any further and degenerates into name calling bullshit EVERYONE step back and take a breath.

this is the only warning don't press me on this.

 

[jdub]

Keep it civil guys or this thread gets locked.


^^^ LOL...
(Ian beat me)

 

[IJ.]

snap

 

[lewis15498]

My bad.

 

[IJ.]

As Idiotic and Cletus an idea I think this is I haven't seen a reason to lock the thread as this isn't "NaziMania" but if it becomes anymore of a trainwreck than it is I'll be pulling on the Jackboots and invading Poland...

 

[jdub]

I'm the same mindset...if you guys want to go to all that effort to prove a point, like I said earlier, have at it. IMO it's a complete waste of time, but I've been proved wrong before.

This thread is a different story...if it keeps going off in a "crazy train" direction, I'll roll the tanks with Ian.

 

[Wayne G.]

Did the valve fall all the way in and is loose in the cyl.? If it did the head must come off.
