Symptoms of a timing belt that has jumped/skipped a few teeth:
  • One Tooth: It will idle like normal and the exhaust will sound fine but cruise and WOT the car will feel like you've got no power and in most cases will hesitate and misfire.
  • Two Teeth: It will sound like somethings "knocking" which is likely the pistons kissing the valves. The car will start and idle but if it sounds like somethings knocking just because it starts DON'T DRIVE IT!
  • Three Teeth: Your bending valves, the car more than likely won't start, & you'll have ZERO compression.

To check it you need to align the timing marks on your cam gears, follow this write-up and take pictures of your results if your unsure.

Lost 40% of power also sounds like your charging system has taken a dump. Not enough current heading to the coils to fire the plugs hot ... I've seen that as well ...

Pull a plug and see if it's all sooty or clean. If it's sooty and all plugged with carbon, that plug is firing real weak.

If you verify that everything on the timing belt side of the motor lines up you need to do a boost leak test (BLT) and if you don't know how to do one there are BLT threads all over tuners and vfaq... Is the CEL illuminated?

It might be your COP setup or if your running a 1g CAS you can get the P0300 CEL randomly as well.

ok i check the timming belt yesterday and my first guess was that my timming is off one Tooth cause i aligned the camshaft and than look at Crankshaft pully timing mark and one time ot was at 5 BTDC and i try to fixed it . I turn the timming belt back a Tooth and lookk again . guess what ?? Crankshaft pully timing mark was not even at the ''T - 15 BTDC '' scale anymore :/ so i guess my timming is ok .
its like bettewn 5 BTDC and T mark . it is like 3 BTDC.

what do u guys think >> ??

btw when i was checking the timming i clean up the crank angle sensor cause it was flood in oil and idk why :/
and the car seem to run a lot better now

Not sure if you've got a camera or a camera phone handy but you trying to explain what you saw with your timing marks is a bit confusing. Just take two pictures, one of your cam gears and one of your crank pulley and where its line up to TDC. It should only take 6 turns or less to get everything to line up like it should.

If your CPS (crank position sensor) was covered in oil you might be leaking oil from your OEM CAMSHAFT OIL SEAL : MITSUBISHI ECLIPSE 90-99.

As an example, heres what mine looked like when I skipped (2) teeth a few years back...

Thanks for the pics and you don't have to apologize for your English, I'm not bilingual and I'm sure English is your second language so your doing better than I am.

Your timing looks good, hows the car feel now after you fixed that #4 injector seal? That P0300 random misfire code could be coming up because of your COP setup, you might try reverting back to stock if you can and see if it clears up.

Thanks for the pictures, it really helps.

i didnt change those seals yet . I will do it tommorow or tuesday .

and with that P0300 code i will try to find some good cheap coil pack and see if the code come back

--one more question

why the car sometime feels like the turbo has a lot of shaft play ??
the turbo is new and it doesnt has any shaft play at all .

its like when i drive in 2nd gear at 2.500 rpm and than go WOT the turbo will boost fine but the car wont have power :/ if i let the gas off and than WOT again its all better

what do you guys think ??

thkns a lott

Sounds like a boost leak, if the turbo is boosting fine but you aren't feeling the power then air isn't making it to the cylinder most likely. That or fuel isn't but then you would know because you would be running super lean.

The P0300 indicates a random missfire IIRC, and our cars are tough on plugs and wires. Are you sure it's not just a missfire. Does it feel a little rough/shaky when it's happening?

My car jumped timing the other day because I have thesee same symtoms like loss of power and stuff after last week when I was doing something in the engine bay and accidentally left a screwdriver near the cam gear and I guess it was a little in it but I went to start the car to test and it got jammed but I immediatley shut the car off. How can I adjust the timing.
