i just bought this crx a few weeks ago. the timing belt was very loose when i bought it. i finally got around to tightening it today as decribed in the honda service manual. the car runs alot smoother now, especially at idle. but it seems like i've lost ALOT of power in the lower rpms (below 3k). it also seems like i've gained some power above 3k. what's the deal with this?

check your ignition timing, by tightening the timing belt you may have slightly changed the timing

 

or check the cam timing. it could be off as well

 

is there any way to check it without the timing belt cover? there were no covers on the car when i bought it.

its a d16 btw

Take the time and carefully do your t belt again. follow each step word for word and u should be fine . Recheck your after ur done to ensure its right

 

Yeah Trust me... Take your Time... My car was the same but kinda different my Results were backwards. Nice Low end... but then HORRILE top end. Comes to find out that my Cam Timing was off a Tooth or So... Pulls like a Charm now =]

 

I just changes the timing belt and now experincing low end power loss. In reading recent posts, I came across this post. Is this something you have had experience in? I hate to think I have some disassembly ahead of me again.

 

i'm getting ready to redo mine right now. i'll post the results when i'm done.

edit: just redid mine. my cam timing was WAY off. go here to see how its supossed to look and compare to your car. http://www.honda.co.uk/owner/C...1.pdf


anyway, back to my car...

i set it the best i could seeing as how i don't have any timing belt covers (no pointers). i used the straw resting on the piston method to find TDC for the crank. then i geussed for the cam using the pictures in the honda manual. it pulls very strong throughout the powerband, but now its misfiring! this is with the distributor in the fully retarted position. it gets worse if i advance the timing...

does this mean its still off? somebody please help, i need to drive it tomorrow.

if its still off, does anybody know which way it might be off based on what i posted above?

ie: do i need to turn the cam pulley clockwise or counter clockwise?

also, i have a timing light, is there anyway i can check the timing without the timing belt covers???

 

more info:

i just took off the dizzy cap. when the crank pulley is at TDC, the rotor is pointing at a 90* angle toward the firewall...
this doesn't seem right(could this be the cause of the misfiring?)

someone please help, i don't want to do anything else until i know what i'm doing

edit:

if i turn the camshaft so the rotor is pointing to the #1 wire contact point, the lines on the cam pulley are WAY off from where they are "supossed" to be.

anybody got any ideas?

 

bump

 

anyone?

 

 

How did you make out?

 

its still sitting. i don't really know what i should do. i was hoping someone would reply with some info

Theres a arrow on the oil pump, line the single white line on the crank pulley @ that arrow on the pump.
Then the the two marks behind side of the cam pulley( at 3 and 9 o'clock), you line those up with the valve cover base(where the Valve cover gasket seats). Thats TDC for #1 piston...Verify by sticking a long screw driver in the #1 piston spark plug hole, when you move the crank the screw driver should move down after TDC; going counter clockwise on the pulley....hope this helps..

 

in the honda service manual it says that the marks on the cam pulley at 3 and 9 o'clock are for use on the d15. for the d16, it says line up the white mark (7 oclock ish) with the mark on the timing belt cover (which i don't have).

I didn't know about the mark on the oil pump tho. i'll use that to make sure the crank pulley is where it should be (it should because i used the screwdriver method you are talking about)

 

So u say you're missing the timing belt covers? If so, go buy them.
