Newbie doing T-Belt replacement

I am the VERY proud owner of a sick lil 92 Lude. I was driving at about 40 MPH and about 2500 rpm or less and lost the timing belt... I immeadiatly knew what it was by the sound of the issue so I pushed in the clutch immeadiatly and coasted to the side of the road. I "Supposedly" had the engine replaced at 98,000 mi (prev owner ran it dry--no oil, etc) Currently have about 36,000 on the "new" engine and 134K on the trannie.

Anyways: (I'm long winded.. :sorry We are finally taking the top off and trying to discover what needs to be repaired.



(immitating the voice of Jamie from Mythbusters WELL... THERE's Your Problem!

PArts List so far:
-One timing belt..
-P-13 Timing belt cover..(has a big ol Gash in it)
-water pump
-belt tensioner
-valve cover seal
-hi performance Spark Plugs

-and I have thought about upgrading or replacing the alternator with a rebuilt or rewound one since it will be accessible??? (I run about 1200W stereo too)

you should do a leak-down test on all cylinders to see if you bent any valves. (is the H23 an interference design engine?)

Honestly I don't know, That's why I am so glad to have found this site. I need MUCH help ordering parts, etc.. I dont want to get taken by some scam artist. I am NOT the mechanic.. lol... My roommate and his father are both mechanics and have volunteered to do this work for me if I buy the parts for the car ... and fix his laptop (I know how to fix computers tho..lol )

I am sorry for my ignorance.. I have been searching the web site.... but I dont understand what that is... sorry

basicall an interferance engine means that when a valve is fully open (to let in air or let out exhaust) it can interfere with a piston at top dead center. Normally a valve is not fully open when a piston is at top dead center so this is not a problem.

but when a timing belt fails, the crank and pistons have enough momentom to keep spinning for a little while whereas the valves usually stop where they are (more or less). This means that a moving piston might come in contact with a stationary valve.

When this occurs, the valve is bent and will need to be replaced for the engine to run correctly.

If you search the board (or the internet for that matter) you can find what a leak down test is and how to perform one. It will tell you if you have any bent valves without having to remove the head from the block.

^^ That's good, I'm glad you found some resources. We are getting pretty good a supporting new members on this forum now, so keep asking questions if you get stuck.

FYI, if you do find bent valves, it will almost surely be cheaper to just find a replacement H23 head (or better yet, an H22 head). Don't bother with actual repairs, just replace the whole head. You can find a used H23 head for around $100 or less if you look.

Finding leakdown testers isn't that easy, and you'll also need a compressor. Just buy or rent a compression tester and it'll easily let you if you have bent valves.

If valves are bent, just replace the head. It'll be easier and mostly likely cheaper too.

Other things to replace apart from what you've listed: Cam seals- the timing belt side of both cams, and the distributor side of the intake cam.

He can't do a compression test, as he has no timing belt. He can use a hand pump, if I'm not mistaken, to pressurize the cylinders in order to perform the leak-down test.

this is great info guys.. thank you..keep it coming please.

May I ask why an H22 Head would be better? I had someone tell me I may already have an H22 Head on it but I dont know how to tell the difference> The picture of the H23-A was taken by the radiator down on the bottom "half" of the engine.. is there something else I need to look for to tell what I have "on top."

p.s. the Ms in LilMsPrelude refers to my gender.. hehehe... My roomate is doing the repairs, he just hasnt worked on Honda's very much so I am VERY anal about getting as much info as necessary to make sure it is done right. if you know what I mean.

That means you can join us over in Off topic and post your picture =p. You can join the small handful of girls over there

Gl with the timing belt change =]. Def just get a replacement head if anything is bent, can be cheaper and time efficient.

quick question, does any one have an extra Helms Manual for the 92??

I couldnt find any Helms MAnuals online from them, but I did find THIS information on e-Bay

http://cgi.ebay.com/ebaymotors...0.lVI I ordered something reminiscent of this that said it was a Chilton's guide, but it was the MOST worthless CD I have ever owned.. I just dont want to get taken again, even tho it is only a few dollars.

92 Helm's Manual

the ebay item looks to be a cd of the helms manual but, getting the real thing is 100% worth it.

yeah you do not have a h22 head from wut i can tell from the pic and puting a h22 head on a h23 bottom end will make you faster can make it unreliable

NIce.... I was told by a local Honda guy that I should put the H22 head on it but it necver sunk in to me what that meant... hehehe... It is my daily driver so it has to be reliable. I often take 150-500 mile trips in it MAny times a year so I need one that lasts. I have a hard time trusting mechanics after the ass that was supposed to have replaced the engine... to me, a newb and NOT a mechanic, NOTHING on the engine looks new to me.. top or bottom.... and supposedly the original issue was a blown/seized engine due to running it without oil.. that's how I got it for $500! And I put just over $2500 into the "replacement." Is there a way to tell based on the cars VIN Number what the original engine was, or serial numbers on it???

sorry for so many dumb questions.

You are doing fine; no dumb questions so far.

I think there should be a VIN on the engine also. I think Honda should have a VIN on the engine block, although I'm not sure where it should be.

Try to wiggle the rocker arms. If you have several loose ones, those are the valves that are bent. When the belt broke on my h23, I had 15 bent valves.
