where do i go from here??
I posted this in problems first but got no responce maybe becuease the question is to hard or to dumb. idk. I'm sorry if posting this again is against the rules. I'm posting this here becuease i really need to tell the machine shop what to do and not waste more money and time. So please anything you say will be helpful.
alright this all started about a 2 weeks ago.
I bought a n/t 6 bolt it's .20 over 1,000 miles on it. he spun a rod bearing crank is trashed. i'm building it up over the next few months and putting it my awd.
well 2 nights ago i was on the interstate and came out of the toll plaza 1st, 2nd, top of 3rd, then instead of 3rd to 4th i did 2nd.... Big mistake about 8500-9000 rpms on my topline internals rebuilt 7 bolt with 10,000 miles on it. Well the engine started to knocked. Only when the rpms would drop though. I got it towed back home.
125 bucks later .
did a compression check from 1 though 4 and they were 135,140,145,145.
then a did a wet test 165, 200,200,200
i guess the rings are shot. idk
i thought i bent valves in the #1 cylinder thats why the wet test was only 165. So i pulled the head no bent valves, no piston damage, all the timing marks lined up. I pulled the oil pan no bearings but there were 3 little tiny stripes of aluminum about an inch long they were in the oil pickup filter. In the process of pulling the crank pulley that was kind of stuck on, the crank moved toward me. first thoughts were mother@$&!er. Crankwalk. now i don't have a end-dial gauge checker but i used a ruler and place it against the block pushed the crank all the way passenger side, measured. Pulled the crank toward driver side the crank moved 3.5mm back and forth. There are no signs of bearing in the oil pan only those 3 little aluminum strips thinner than a paperclip. Are they peices of the thrust bearing??
This is half of it. So i go to the n/t block flip it over the crank is still in it and hasn't been taking out yet so i push on the crank and it moved too. I'm like what the crap is going on. It's a 90 n/t 6 bolt with a spun rod bearing. That crank moved back and forth 2mm. I brought the 6 bolt to the machine shop today and he said that who ever did the rebuild on the motor before installed the thrust bearing in the wrong spot they put it in the cap closest to the flywheel. The machine shop owner said that is the reason the crank was moving. Does this sound right?
He is still going to take the rest of it apart, get a good core crank and check the clearances. Should i trash this n/t block too or what? i don't want any more problems with moving cranks!!!
Please help me out!!
