I've spend days reading through forums posts to try find my EXACT problem. I've found many posts that have similar symptoms, but none with a solution to that made sense in my particluar case.

With that out of the way, I have a 90 Eclipse GSt on which I have just completed a 'rebuild'.

I had to 'rebuid' the engine because my timing belt broke and all my valves were bent beyond belief (welcome to the club, right?). So I got myself a rebuilt head that had a new professional valve job and a machining to level the surface. I have put on a Cometic gasket with copious amounts of copper spray to get the damned thing to finally seal. New timing belt. Everything seems to be GREAT, except one little (read HUGE) problem. There's a 'noise'. Not just a quiet little lifter tick sort of noise. A rattle the whole car, sounds like rapid fire hammers in the block, makes you wanna cry, sort of noise. I found someone that had recorded the sound here: http://www.midnitetuners.net/videos/tick.avi

Even after running the car and setting the timing to 5 degrees the ungodly sound remains. It does it from start, cold or hot, and persists when the engine hits operating temperature.
ALL timing marks are lined up to perfection, and this is not the same sound I had when I had piston to valve contact (that is one sound I will NEVER forget).

And to top it off, I have oil spinning out from behind the cams that has 'saturated' my new timing belt (which is not my major concern now).

If you need more information to help me figure it out I'll be glad to add what ever else I have to offer.

thanks in advance all ye holy dsmites.
 
Sorry, I don't have speakers on the computer I am currently located at so I cannot listen to the sound however I will throwout a possibility. If you have it perfectly timed like you say you do it could very well be a collapsed lifter. They will make an ungodly noise that makes your heart sink. Again, I might be wrong I can't listen to the noise. Just throwing out a possibility. :thumb:
 
ya it definetly sounds like a lifter issue.. did you clean them out or replace them when you did your build up? you should start by pulling the valve cover and putting the cam seals back in because its apparent you forgot them.. while doing that check all the lifters remove them clean them get the big bore revised 3rd gen one's

here is the faq for checking and cleaning them http://www.vfaq.com/mods/lifters.html

good luck..
