95 honda prelude with jdm h22 swap. 5 speed. Ok so just purchased this car a week ago. Ran great. Then it started making noise form the timing belt area. Upon research I found that the auto tensioner are garbage. Bought a kaisenspeed tensioner and installed a new belt today. Car made it home. To the store. Then on my next trip out it stalled out at a stop light and I can hear the sound of a loose belt. Immediately cut her off and spelled the upper timing cover to find the belt had came loose somehow.
I had replaced the belt at honda and had techs check my tension and installation. I'm beginning to wonder if I'm missing some spacers or washers or something. We had a problem with the belt walking off the cam and making noise. Loosened it up a bit and worked fine. I'm not running a balance shift belt but still have the the balance shafts, pulleys, tensioner installed.

1. Are there any big washers or spacers anywhere I could be missing? The guy that owned it before me changed the belt and reused the auto tensioner so obviously didn't know what was going on.

I did notice my valve cover is leaking on that timing belt side. Could the fresh oil have caused the belt to slip or something?

I'm gonna attempt to take it apart again tomorrow and try to find the issue. Any help or suggestions is greatly appreciated

Just the washer on the crak pulley. Why did you not reinstall the balance shaft pulley's ? The parasitic HP loss is minimal.

Gas mileage slight power. The car didn't come with one on it and I didn't notice any vibrations so I didn't worry about the extra work.

By washer on crank pulley do you mean the giant one that sits on the crank pulley bolt?

I'm guessing the tensioner bolt is broken. Gonna take it apart tonight to see what happened. Pray to the lude gods that I don't have any bent valves

Ok found the issue. The kaizenspeed manual tensioner jam nut cam loose (probably due to vibration from lack of balance belt smh). Still praying that no valves are bent. Gonna pick up some thread lock tonight and a valve cover gasket and I'll try to start her tomorrow. The timing was horribly off so it looks like I may end up having to buy a new head..

Like 5-8 Whp...depending on mods... not that minimal.

If you need a new head (or machine work done), I have one for sale and would take yours with bent valves on a trade... as long as the valves did not damage the combustion chambers. Fresh from the machine shop, new valve job, ported, polished combustion chambers, resurfaced at .006, Supertech valve guides and seals, etc. Have the JDM camshafts, cam caps, and rockers and all that stuff with it too. PM me if you need one and we can negotiate a deal.

Also the KS tensioner is awesome, just got to make sure that jam nut is tight enough. Defiantly was not because of the lack of the balance belt. Sorry you had that experience... really sucks. but on the bright side at least you know exactly what the issue was.

Thanks unfortunately I'm short on funds so I think your head may end up out of my price range. When I set the timing I kept turning the crank til I saw a mark through the inspection hole. I've read there are multiple marks. I should be looking for the + sign for tdc? I'm gonna redo it tonight with an extension in no.1 spark plug hole to make sure I'm at the right mark. Loving the kaisenspeed tensioner though so easy to adjust. Thread lock should hold it on this time

Timing marks are http://qcwo.com/technicaldomain/tag/...specifications
They should be at that position when the crank is at TDC. Just use the mark on the oil pump housing to set it at TDC, and then check the cam gears. Everything should line up. If not, then do a leak down test and determine if you need a valve job/new head.
If you do need a new head, just PM me with an offer... maybe it is not out of your price range after all.

not even in the slightest. User error.

if you didnt tighten the nut enough, it can back off. no need for locktite as you will never get it loose again unless the engine is out.

I've used the tensioner on my race car, my weekend car, and two customer cars. race car saw 11k rpm without a hint of the belt coming loose.

True however my paranoia is getting the best of me. I'll use a small dab of rtv gasket maker to ease my mind. I bough a tiny 10mm wrench that actually fits up in the hole with room to spare without removing any engine mount bolts. Very exciting.

crows foot

bdmlilburn

still have not invested in a crows foot set but its on my to do list. got the car all back in timing. cranked counter clockwise by hand and it stayed in time and didnt get stuck at any point. used a small amount of honda low strength thread lock on the jam nut and tightened that thing as much as i could. funny how i was able to do all this and get it all back together without having to raise the car or drop the engine at all.

bought i valve cover gasket from honda but no one seems to have the grommets or a full valve cover set around here. my grommets are old and useless and not allowing the valve cover to sit tight enough. advanced autos online site says a few of their stores have the kits so ill be calling them tomorrow on my lunch break and hopefully i find one i can pick up after work.

Alright guys the lude lives again. I did use a small dab of low strength thread lock. I broke the jam nut free today after letting the thread lock dry 24 hours. No problem breaking it at all. Again used another small drop. The engine sound s great and idles perfect so dodged a bullet there. Thanks for all the help.

Sorry 1991_crxsi I was not looking to affend anyone. I am a Marine Diesel Mechanic by trade 30+ yrs, and in " that world ", 5-8 hp increase is negligible and not worth mentioning. If an engine dyno's at 458 or 471 it really doesn't matter. Again, I appologize if I have offended anyone.

You're good buddy. In a N/A application, our little engines and light cars make objectively smaller gains more appreciable.
