Loud Clanking/Knocking Noises from KA24DE

[dSl-DuDe]

Ok, Today while driving up a hill in my 92 S13, I somehow managed to do some damage to somethin.... I'm not exactly sure, but now when I start it up I get a fairly loud knocking close to the back of the engine.. I was driving at around 5k RPM up this hill for maybe a minute or 2, after the hill was over i heard the knocking noises and a bit of a power loss. I've done several searches on the boards but cant really find much info on the ka24DE noises, other than that its a valve problem. I think the problem was caused by oil starvation, because my oil was REALLY low when i checked it afterwords. After filling it up I still get the loud knocking. I also had a more subtle ticking coming from the engine just after i replaced the timing chains a few months ago, sounded valve related and was only noticeable at low rpms.

I'm really puzzled here to what the problem is. I've pulled off the valve cover and everything looks ok under there.... do i need to look farther into the engine or what? Any help; suggestions??

edit: oh, the engine has 118k miles on it, full timing chain done at 117K

yeah..that engine is done. the oil pump and pick up are in the front of the engine, now when you're going uphill (and severly low on oil), what part of the oil pan does the oil go to? the back. So all the oil is in the back, no oil in the front (where the pump picks it up), and you're doing 5,000rpm for 2 mins. I think you get the idea.

:fried: < heat + friction__^your enginewith no oil

yeah I think he has the idea, but still you haven't answered his question. What might be the problem and so on, maybe you guys could even help tell him what he needs to fix it. I don't know or I would have add something more useful.

well, i believe its the the rod bearings..... I'm on the hunt for another KA to drop in (hopefully with a nice low mileage.) Possibly willing to pick up in and around the seattle area, otherwise local perferred in Vancouver,BC, Canada

pay attention skip. If an engine isn't getting oil it's obvious to anyone with a clue that it's the bearings. If from what I posted previously anyone couldn't gather that it's the bearings, then they shouldn't bother trying to fix your car over the internet, take it to a mechanic. As you can see dSl-DuDe suspects rod bearings.

If the damage wasn't too bad(excess wear on crank journal or scoring) the you may only need to change the rod bearing(s). Rod bearings are fairly cheap and it's easy go get to. Just need to remove the oil pan for access.

Skip.... Yeah. The deal is that everyone figure from Dsl-DuDe post what happened, you were just an idiot for stating obvious, instead of helping the guy out, that was my point, as well as that are other thing that can happen when an engine is starved for oil the just the rod bearings.

Thanks for playing

aww c'mon skippy boy, why'd ya have to be so mean?

If I stated the obvious, then how come you said "I don't know or I would have add something more useful.". It may have been obvious, but certainly not to you. When an engine is knocking the way his is, what do you think happened? It's the *****ing bearings dipsh*t. Don't play games and post nonsense. You don't remotely know what you're speaking about so don't try to appear as you do, it's best you don't even post at all.

If you were of average intelligence concerning engines, you could have gathered that I was implying the bearings are shot from my original post. You obviously didn't. Why? Simply because you're stupid.

I don't know or I would have add something more useful.

In the end thats what it boils down to. You don't know, and your posts are useless. So here's a hint for you, go educate yourself and then come back, maybe then you'll have something to offer rather than "I don't know".

take it easy skip.

why are u arguing about such trivial ****

make a joke about it lighten up guys

[dSl-DuDe]

ok, i'm contimplating just replacing the rod bearings by dropping the oil pan? think this is a good bet or would it be a waste due to oil starvation straining other engine internals?
