Hey guys, about 2 months ago my s14 died while i was driving. I was going about 40mph at relatively low rpms when i noticed that i wasn't getting much of a response when hitting the gas. Over about 30 seconds to a minute i lost more and more power and eventually it stalled. I had it towed home and did every test possible. I had spark, had fuel, but my compression was low in all four cylinders (below 60). When oiled the compression went up to 120 in all four, but it still wouldn't start.

SINCE THEN i have done the following...

Tore apart the entire motor down to the pistons, (#3 was chipped between rings and #2 had some sort of abrasion on the top with the same matching mark under the head.

I bought a newer ka24de with much lower milage (mine had 202k, this one had 115k). Tore apart the new one to find it had a bent rod in #1. I used all the new pistons from this motor and threw them in mine, and replaced the rings with brand new ones from Nissan. I also used the head from the new motor, since mine had marks on the bottom and i didn't want to risk it.

Another problem i had was my timing chain guides and tensioners. 1 guide was totally destroyed, in pieces, laying in my oil pan. I replaced all tensioners, guides, and chains.

After all this i reassembled the rest of the motor and filled it up. When i attempted to start it, I GOT THE SAME EXACT SOUND IT WAS MAKING WHEN I TRIED TO START IT BEFORE. It cranks but doesn't start. Use your imagination.... and this is kind of what is sounds like...

crank....crank....craaaaaaannnnkkkkkkkk (brief silence) xhowever long i turn the key.

Please help friends. I've put over 30 hours of work into this motor.
