Re: Rebuilding Ty #284
Got trolled.
As documented I had my engine rebuilt about 2k miles ago. As also documented its failed 3 times, and each time was a crank oiling issue. Wait..make that 4.
I decided because my blazer was down i'd take the typhoon out and do some good ol fashion autox, and it truck did great.
I like the little rocks flying off my tires.
Now, as stated it did great autox. Motor has 2k miles on it since rebuild. Has been driven pretty easy. Tuned on E85, low timing, no knock ever since changeover. oil was pull out 2 days before and was great. oil pressure was good. Did autox across state.
About half way back I noted my oil pressure gauge moving from 'normal' psi, to about half of that, and then back. It would do that suddenly, with no other notable signs, and then move back to normal. When I stopped next I could hear the beginnings of main bearing failure.
So...
I decided that I hate this motor. It has broken 4 times now with no real reason to fail. I tune this engine myself. I have both built the motor myself and had it built professionally. Nothing has ever looked bad, pistons always look great, rod bearings too. Main bearing failure time after time. I give up.
I decided that my best and most cost effective move would be to buy a newer votech motor out of a newer truck.
I have done mild research on the topic and discussed it with people I respect greatly. the block is apparently nearly identical. The timing cover is different, and at some point they put balance shafts in making new cams difficult. The heads are obviously vortec making it expensive to use, but I decided best option was to just bolt my L35's on and go. I am not sure about flexplate stuff yet, but I am sure its not hard to figure out.
I picked this up for 300 dollars with a bunch of extra crap. its around 150k miles, and I tore it apart a bit and it looks very clean in the inside. Rod bearing are all good, cam looked good, no gunk, oil was very black and clean. has correct 4x4 aluminum oil pan. I have a good feeling.
While I have it apart I am going to have the same guy who did my th400 rebuild my 700. Its shifted sorta funky bad since that spring went missing inside the kick down valving...
updates will hopefully come soon.
