Well at a brush pull last thursday night i popped my S472.

Heres is what we have drawn a conclusion to what happened.

It all started with a cracked injector or maybe more I DK. These are hard to detect as no scan tool can find them you just have to visually see it, which you cant. When LB7 injectors crack they spill all the fuel into the crankcase. Thus diluting the oil. This is not good for engine bearings. Since I used the PPE install kit my S400 was fed off of the stock location which recieves its oil through a slot in a cam bearing. However diesel fuel is not a good lubricant for cam bearings, thus it spun and there was no more slot which meant no more oil going to the turbo which is no good. This caused the bearings to fail in the turbo and the wheels to rub the housings pretty much ruining everything except the center section. This is just an assumption of what actually happened.

So with all these issues plus all of my other broken parts (bent rods, 3 broken shafts in front end, twisted driveshaft) i decided to throw in the towel and call it a season. I have the motor ready to come out but have an injector job to do on an LB7 and some other projects. So someday ill roll my truck back on the lift.

Ill be going through the trans and freshing it up and adding some other goodies as well.

Ill also be sending the injectors the SJD to find the bad ones.

Then for the motor, well I DK probably build it for next year.

Turbo, not sure. I may build the same one or build it bigger and pick up an S300 and fab my own twins.

Time and money will tell but ive got a lot of time to work on it now and finish things ive always wanted to fix.

Heres the video, you can hear the screech at about 150'.

 

 

ouch sorry man thats no fun sorry to hear

 

ifyour going to tear the engine down you might as well just build it right, rods, cut pistons, keyed crank, all the rest of the stuff.......

 

i most likely will be but i dont promise anything.

Ive had this thing out and tore down twice this year and havent built it yet.

 

sucks man its still early in the season too

 

that sucks man, hope when u get it goin, its better than ever.

 

Good luck w/the rebuild.

 

Sucks *** Vinny I was wondering what happened.... Havin fun on Johnnys truck I hear as well. Gonna have to charge him some more money now....

 

Well turns out cam bearing is fine and most of the turbo can be salvaged. It only needs a good cleaning of the housings, new wheels and new journal bearing. But its not getting rebuilt to the way it was. Some fancy things might happen.
