Ka24e rebuild

[m_sanchez4522]

So I have a ka24e that I am rebuilding it actually came out of a pickup, before pulling the engine I was sure it had a failed headgasket but it also had a knocking/rattling noise which I thought to be a spun bearing or bad rod because there were metal shavings in the oil, to my surprise the bearings were fine all rods and pistons were intact and I even still have the factory honing marks on the cylinders (190k miles). I found out the noise was coming from the timing chain that was very loose slopping around, one of the long timing chain guides had broken off of where it was was mounted and got broken into a million pieces, since the timing chain was so loose and slopping around it was rubbing up on the metal pieces that hold the middle and left guides I know I can replace the one on the left because I can just remove it with an Allen key but the middle one can't be removed and it's almost half of the way shaved down from the chain rubbing on it I just need to know if this is going to be a problem rebuilding the engine. I will also have plenty of questions down the road since this is my first rebuild.69839 here is a pic of what it looks like the pic is sideways.

Seriously, you took a motor that was running and that's notorious for a loud timing chain rattle, and ripped it apart, because it was rattling?

Maybe you should put it back together, before you screw it up more. If it doesn't need rebuilding, it doesn't need it - you'll probably never get it as good as it is now.

I'm fuzzy on your problem - but they make screw removal kits.

Ok so maybe i wasn't clear when I said the long guide that goes along the chain came off and there are metal pieces all over the engine including under the bearings which caused a lot of damage to the crank the engine also needed a new head gasket and possibly some work on the head because there was a lot of rust from the bad gasket it wasn't just the "notorious" timing chain rattle as you can see the timing chain messed up the metal mounts where the guides go I'm wondering if this is going to be a problem down the road plus the engine has almost 200k which is why I don't mind using it to learn how to rebuild an engine.

And a screw removal kit won't help because the part that is messed up is not screwed in its part of the block

And maybe I can get some help from some who really wants to help people and listen to there problems instead of someone who just wants to give us who don't know everything a hard time.

I'm not positive on this but I don't think that's actually part of the block. I'm pretty sure it's a pressed in dowel pin. If it is u have a few options. None of which are a quick fix. U can try drilling and tapping the top as deep and big as u can and use a slide hammer to pop it out. Or u can just can cut it down and just drill It out. Make sure u don't blow out the hole to a bigger diameter than the I.d. Of whatever it is that sits on it. Then get yourself a dowel pin of the correct length and diameter and hammer it back in.

Might even be able to get a good grip with a pair of vice grips and wiggle it out as well... Hope this helps [emoji106]

Ahhh ok I'll have to try that thanks a lot man it's so hard to get help, even on the forums a lot of people just wanna bash newbies.

[yetijeff]

My advice to u with that is always always always search and google and everything you can before creating a thread about something. A lot of people on this forum are trolls but the majority who would know are willing to help you if you help yourself first. But when people ask questions that've been answered elsewhere. A million times. I get how they can b dicks. It makes you seem lazy and want aaaall the info fed to you. Ur question is pretty specific and I doubt you'll b able to find a thread on it.

[m_sanchez4522]

Ya I understand that I did look for this places but I didn't find anything thanks again though

Can you take a shot slightly further away so i can see the profile of your block ? i know your talking about the timing and what not but i need to see a slightly further away shot to see what your talking about specifically.. I've rebuilt my ka and taken them apart many times.

Hope the rebuild turns out !

*EDIT*

After looking at an extra block i have outside i see exactly what your talking about.

You'res seems like it forsure got alot more rubbing. Mine has some scoring on it on the right side of that prong.


But ultimately that prong is not designed to have anything on it so i dont think it will matter if you replace it or not. It just pretty much is there. It must have been the tensioner failed and caused way to much slack on the chain.

If you look at this picture right where the prong is... nothing rests on it or slides onto it. So i dont think its something to worry about. Just gotta make sure your chain tensioner is properly working next time.

[m_sanchez4522]

Ya thats weird I wonder why it's there? I thought maybe a circular guide when on there or something.

[BoostSlideWayz]

Well i believe its there to help keep the chain from entirely binding up from not enough slack. Obviously this thing did its job.

Id imagine if that wasn't there, the chain would have probably started touching the other side. But yeah it's been a couple years since i built my motor and it may have a roller on it but i dont recall anything that goes on that prong.

[m_sanchez4522]

Ya that makes sense the head,block and crank are at the machine shop now after I get it back I can work on putting it back together and in the truck, any tips for someone who hasn't done it before??
