is it rod knock?
I've never heard rod knock, or any knock for that matter.
My freshly swapped h22 is making some strange ------- knocking noises. I bought it for $400 from some guy in Jacksonville. He said the motor had no problems. ::) Anyways, I got it running yesterday and it's makes some knocking noise. I'm trying to figure out exactly what it is and if it would be an easy fix. http://s64.photobucket.com/albums/h1...nt=blah008.flv Thats a video of it. Don't pay attention to the actual video, I was trying to get the camera in the best position to hear the noise. Here's one from the engine bay. The noise I'm talking about is the low/deeper noise you hear towards the end of decel. That video was prior to doing a valve lash adjustment. It's much quieter now, but it still makes that knocking noise. http://s64.photobucket.com/albums/h1...nt=blah007.flv It sounds like a normal engine at idle(besides a slight valve tick), but when revved up it doesn't make the noise until at the very bottom of decel. It takes a certain load for it to make that noise and doesn't make it during decel while in gear at all. The engine seems to be running strong from what I've felt so far(took it to 7k once). Worst case scenario is the crank is completely fucked. I will replace the crank with an f22(95mm) crank and rods and use the h22 pistons to make an h23vtec. I just need this motor to last a few weeks going to and from work(20 miles one way) for a few weeks so I can save up money. |
Re: is it rod knock?
in the first video, it sounds to me like something mounted to the engine is hitting something. i have heard rod knock quite a few times, i have spun plenty of bearings in my day. i really couldnt hear anything in the 2nd video. who did you get it from in jacksonville? i know quite a few people there. that might help in knowing if it was someone that would do something like that.

Re: is it rod knock?
did you replace the timing belt?
if so you might the balance shaft out sinc. |

I've checked and checked again for anything rattling or hitting the engine and I can't find anything. I have poly filled mounts so they're solid as a rock. The engine don't move for ----. At first I thought it was my downpipe hitting my front crossmember, but the downpipe doesn't come close and its solid as a rock. I can barely budge it with a big screwdriver. |

Re: is it rod knock?
that name sounds familiar but i cant find him on any local forums i am on. i did find him on cb7tuner.com and i have seen his car around, but i dont know him.
how is your oil pressure? most of the times i have had a rod knock, my oil light would come on at idle. |

Re: is it rod knock?
it sounds like the noise is coming from the bottom end.
Check your exhaust for leaks. About 11-12 seconds in on the 2nd vid...look to the right of the header, there's a little white thing that moves over an inch or 2 when the engine is revved. I dunno if its a coincidence, or the cause The rod knock i experienced with my h23 was horribly worse than that. It made all kinds of sounds at all rpms and all loads. I've also have a clutch go out on me and that sounded like rod knock, but drove worse than limp mode. Check you oil for metal shavings if you haven't done so already.... |

Pulled it apart
here's 1 of the bearings. They look pretty much the same. Attachment 13684 Here's how all the mains look. Attachment 13685 The pistons seem to have some scoring on them. Pretty sure they're still salvageable though. Attachment 13686 Attachment 13687 Here's 1 of the thrust washers. The rest are actually worse than this one. Attachment 13688 Attachment 13689 Bottom of head Attachment 13690 summary Attachment 13691 There was some definite oil starvation going on. I'm going to replace the oil pump and clean the block oil passages thoroughly. The crank didn't have any deep scoring, just scoring on the surface that I'm sure can be removed by turning/machining the crank. I'm just gona go ahead and build my h23 vtec. I have a good crank and brand new bearings. I have to wait to get some money though so I can take the f22 piston/rods and h22/piston rods to the shop so the h22 pistons can be pressed onto the f22 rods. After that's done, I'm going to save up for an oil pump, unless the f22 can be used. Also plan on using arp headstuds and do a valve job while the head is off. Should be good for an easy 200whp NA out of this motor. The compression will be close to 11:1. Plan to throw boost at it later down the road. But in a different chassis. |
Re: is it rod knock?
damn, that sucks. i would send those pics to the guy you bought it from. thats shitty.
boost on 11:1? :o i know its possible, but not real easy. |
Re: is it rod knock?
I don't plan on doing more than 10psi. I want to reach 300 on stock internals. I'll be more than happy with that. For a daily.
|
Re: is it rod knock?
i wonder about stock pistons with 10psi and 11:1. aftermarket pistons i wouldnt worry about, but the stock ones worry me. im no expert though. it might be just fine

Type r swaps get boosted all the time. Your fine |
Re: is it rod knock?
Those pistons are trash man unless the picture is making them alot worse then they are. Bust out the carb cleaner

If it was a business sure random dude he should be happy the head is good and it even started even with trashed bearings Im also not a fan of turning cranks has in reality you can find a used crankshaft for cheaper than the machine work from someone like myself who has 2 of everything like Noah. |
Re: is it rod knock?
I have seen alot of people on here say not to turn a honda crank but why is that ???
|
Re: is it rod knock?
i dont know why anyone would say not to. stock cranks have no problems taking all of the HP thrown at them. the tiny bit of material you take off to make it smooth isnt going to weaken it any
|
Re: is it rod knock?
They are not supposed to be turned ask your local honda mechanic. Turn it and enjoy trashed bearings.
|
Re: is it rod knock?
So you really think those pistons are trashed? Got any spare USDM H22 pistons? How much? I'll probably pick up one of your throttle bodies too.
|
Re: is it rod knock?
holy ---- that sux. Those bearing definately took a beating. At least the block is still good.
Why dont you just see if you can find some h23 pistons/rods and keep the compression down a little. just my opinion. That way you can just put it together without having to change the rods. Those piston skirts do look a bit fucked... don't know if u've seen this thread on HT....but it might help if u need it http://www.honda-tech.com/zerothread?id=1232811 just tryin to be helpful |
Re: is it rod knock?
Yup, it's in my bookmarks.
If I could find some h23 pistons/rods, I would definitely buy them. The compression on the engine was about average as far as h22's go. Most JDM H22's are just about the same. 1-4; 205-210-210-220. That's what makes me thing the pistons are still good. |

Took it apart and found the gears broke into about 7 pieces. |

That's what makes me thing the pistons are still good. Like I said the pictures may make them worse then they are. Try some scotch brite to clean them up. If you feel deep grooves on the wall of the pistons I wouldnt use them but if its all you have well they will work just wont be the way i would do it. Me before I got paid to do this ---- says ---- it run it |
Re: is it rod knock?
I can't feel anything when I run my finger nail across the skirts of the pistons.

Re: is it rod knock?
I'm getting a set of JDM H22 pistons for CHEAP. Hello 12:1 compression :S I'll probably end up getting a .052" cometic head gasket to lower it a bit.
I'm also getting a set of brand spanking new ACL Race bearings for FREE from the same guy that's selling me the pistons for cheap. I'm trying to figure out the oil pump thing. I have a nearly new (10kmiles) f22 oil pump from Toga. I looked up part numbers on importperformanceparts.com and they showed the prelude's f22a1 has the same pump as the h22 does, but the f22a1 from the accord has a different pump. :S It would be another thing that explains why the f22a1 from the lude has 10hp more than the accords. But Honda shows the same part # for all f22a oil pumps, regardless of chassis. You guys think using the f22a oil pump on an h22 is a good idea, at least for a short time while I save up for an OEM h22 pump? |

Re: is it rod knock?
Ok.
You know of any other source of h22 oil pumps besides Honda? Them bitches are EXPENSIVE. |
Re: is it rod knock?
my h22 has ~230ish across all 4, but above 200psi should be good either way.
I know bigdaddyvtec says don't do it....but if it fits it should hold up N/A with minimal abuse. But if ur putting the h23/f22 crank in with the h22a pistons....i would keep an eye on oil pressure, and make sure u don't rev the piss out of it. Do u feel any scratches when u run ur nail down the sleeve? Make sure u get all the shavings out of the block... Is there a way to check the oil squirters for shavings? or are they filtered somehow? http://www.hondaautomotiveparts.com/...P-OIL+STRAINER [size=10pt]#5[/size] |

Re: is it rod knock?
looks like someone forgot to change the oil a few times.

Re: is it rod knock?
Find a used pump
|
Re: is it rod knock?
do u have any used h22 oil pumps
|
Re: is it rod knock?
I did have like 5 of them. Sold them on ebay for 25 shipped
|
Re: is it rod knock?
|
Re: is it rod knock?
i believe i still have the oil pump from the h22a block.
|
Re: is it rod knock?
How much you want for it?
|
Re: is it rod knock?
spiker or blake, you guys have those oil pumps? I need one asap.
