Buddie just had his motor go heres a pic of the carnage. Thought id see what everyone's diagnosis is on the cause of the failure i have my opinion and he has his.


Edit: ill forgot some details
its a d16 Vitara/Eagle motor and yea they are forged h beam rods. snapped the ARP rod bolts and spun the rod bearing.

My diagnosis is oil pump failure under high boost heated up the rod to bend it and spun the bearing.
He thinks it was a faulty wastegate and a failing oil pump spun the bearing
( oil pump was oem d16y8 with ~200k on it.)

 

just a wild guess, but looks like he bent a rod. i mean, without any kind of information as to what his setup is, i think it's a pretty good guess.

 

Looks like an eagle rod or some sort of h beam how did he bend a rod that bad ?

 

Details added

 

Thats where we both have different opinions. ESP a Forged H beam

 

most likely its was starved for oil and spun the rod bearing causing the big end cap to break or sheer the bolts from overheating and the bent rod is from impact

 

Its just sad as the motor was only 6 months old. maybe 8k-10k on it.
I have the same motor setup but i opted for a new oil pump over reusing the stock one and im sure glad i did.

 

geez never reuse a stock oil pump there cheap lol

 

yea he cut a few bucks there but lost alot more in the long run, the rod also took out the oil pan . His crank, Rod, piston, cylinder, and oil pan are all trashed

 

My thoughts exactly

 

wait a minute, he took the time to replace the entire bottom end with eagle H beam rods, and pistons, yet left a 200,000 mile or more D series oil pump on there?

 

Dumb.

 

My thoughts exactly.

At the time he was pushing 20lbs on a 57trim t3/t4 turbo and blew this rod right through the oil pan.

 

who tuned it

 

Hey guys just got my cat built, tell me what you think...

 

its rare to see an eagle bent like that lol.

 

My thoughts exactly!

One of the local tuners by him in CO tuned it. he also has a wideband setup to watch AFR.
