7A-FE Dieing, bad knock sure its 3rd cyl Options

[Soulend]

Hey everyone,

so its not a TOTAL loss because I have a near completed 3S-GTE sitting in the garage. but was wondering if it would be semi-'easy' to repair this: http://www.youtube.com/watch?v=FTWFLFDgtow

so I can get the engine finished...

any help or suggestions?

Thanks,
Kevin

did the ticking just start happening?
Also, a few other members on the forum mentioned they had a ticking with the 7a-fe.
I personally don't know how to fix it, but I would believe you might have to tear apart the engine
You could drive with it a little bit longer, but you would definitely have to take it easy.

yeah, it started last night, I was on the freeway going about 70mph (speed limit is 65) and all the sudden there was a very heavy feeling on the peddle, and i had to acceleration. when I got off the freeway 5 minutes later, I heard it for the first time. I think a valve opened at the wrong time or something and got slammed bending it so it stays open or something... the spark plug was covered in oil and the piston was also covered in coated in oil.

we'll see how long it will last... thanks for your info

By that sound in the video...shes dead jim.

That certainly is not a tick, but a definate knock of death.

No dying, that things dead. More than a lifter tick unfortunately

woahhh, i didn't know it was that bad. definitely DO NOT drive it. it is dead, sorry to say. If you keep driving it like that you will lose a ton (or all) of the the oil and things are bound to get even more F'd up if you keep driving it.

ya lost a bearing. keep driving it & it'll throw the rod. you probably need a new rod, and a crank regrind (or new one) along with a full rebuild. minimum cost: $2000

[stephen_lee]

if you stopped driving it as soon as you felt a power loss, you could PROBABLY get away with just replacing the bearings and squeeze another 10,ooo miles out of it... in that contition id say the motor will last at MOST 20 miles

the Engine will be rebuilt, was planing to do that after I got the 3S-GTE engine in. it was going to be my "learn how to really work on an engine" I'm a bit upset this is how it had to end. but just means more to learn I guess.

as for the loss of power, I've been getting hic-ups in power here and there, and my father, who shares the car, was thinking it was the spark plus and some to do with the clutch slipping.

I was hoping it would hold out till October, but it didn't make it...

Ill start pulling the engine this weekend and get the bay cleaned up for the replacement.

Thanks for the hard truth though!

if you want my advice.. replace that rod. it was under tremendous heat/stresses and you should be able to see that its discolored (if you can see through the oil buildup). its probably slightly bent or out of round, and reusing it will cause the same failure. replace ALL rod/head/main bolts with new toyota bolts. get the crank checked (it may be able to be saved).

btw, i had a 7a fail in the same way.. but i DID keep driving it (i was FAR from home)
