sorry, forgot to list the car / engine

its a 2003 lexus IS300, 3.0L inline 6



sorry that the the pics were down earlier, his webspace was down and i had no way of getting the pics, i just had to wait for them to come back up again on their own

as for them mention of detonation, thats very well possible, it had 1700 miles to do so, especialy the 1000 or so he put on it totaly untuned ..... and even when he DID have it tuned, the emanage piggy back computer wasnt fully hooked up, so its only tuned -basicly- for idle and full throttle, anything inbetween and it runs like dog-do

on top of that, he "modified" his blow off valve when it didnt seam to want to work correctly ... and it STILL doesnt work correctly

and for everyone that either said or THOUGHT i shouldnt touch this car anymore, your right, and im not going to .... i refuse to have my name drug thru the mud when he blows this thing up again

in fact, THIS was my final comment to them :

Quote:
Nissan240sx: i got $10 on it blowing up again by the end of the year
Nissan240sx: ill expect you to pass me my winnings thru the future hole in the block

destroyed con rod bearings - pics and description - what happened ?

I have just started reading this post, but all I have to say is" Stupid Is As Stupid Does!" I would think Detonation got the first one and dirt and ignorance got the rest. I have seen motors turn rods blue and eat bearings on start up due to improper clearances and improper torque. Another thing is to prelube and pump up oil pressure on initial start up, a dry start will kill bearings. And once the bearing scuffs it is not going to get better, or stay the same, only worse.The days of chassis overhauls ended a long time ago, I don't even think it is used in diesel repairs anymore.

I pretty much agree with everyone else. I would think one of the main problems would be that the motor was full of metal shavings from getting it honed and not properly cleaned. If you have low oil pressure on top of pieces of metal in the little oil that is seeing the parts, you are probably going to have bearing failure.

Well, you learn the most by personal experience and your friend is certainly learning alot. Too bad his builder buddy is a complete moron, it is a nice looking car. Why don't you offer to help your friend learn how to build an engine the right way?

And would you really trust the rods after bangning them around in there, you know the engine will always let loose at the weakest link.
But the rods seemed tight enough...who needs that expensive plastigage anyways? Too much tolerance, a hefty dose of detonation and some moron with his foot to the floor can do that type of damage in a hurry.

k-star is right also, I am going to assume that since checking clearances isn't high on this "shop's" priority list then neither is cleaning anything.

IS THIS BAD ??? Just Kidding: man there clueless. where did the landscape shop guy think the honing burs and slag was going to go ? think the crank was even wiped off ? the crank would of been in the engine unless they pulled the tranny ect. not to mention where the metal shavings and spurs & burs from the 1st failure went ? you could not pay me to reuse them rods. any idea what shape the block mains & block main caps are in ? not to mention the cam bearings.

what does 2003 lexus IS300, 3.0L inline 6 parts cost ???


where did the landscape shop guy think the this was ment to be a funny

Doc here,

Well, the photos finally came through..and saw the crankshaft and bearings for the first time...

Send my Congratulations along to "Larry and Curley"... (or Ralph and Norton..Whatever applies the best..) They've taken a perfectly GOOD set of bearings and a Steel Crankshaft ... and invented an Edison Wax Disc Phonograph...

To play 45's..they probably could use the cam at the same rotation speed..

ALL they need now is a sound horn, and a needle to pickup the grooves as it turns..and let's not forget the Dalmatian with one ear to the sound horn with the quote "His Master's Voice" below it..(you real Olde guys know what I am referring to..)

To reuse anything from that block , would require a clean up tantamount to cleaning up Three mile Island for re~population again..

Pass along the information: Oil is sold by Weight...Not Grit...

Were it I, I'd do something useful with the block..like pull it, place it by my mailbox..fill each cylinder with potting soil, and Daisys...a Functional yard Gnome..At LEAST then it won't matter and Actually augment functionality by adding MORE dirt..

Doc

It looks like your friend was made for that shop. Takes a car not tuned, flogs it hard, til it makes bad sounds, and keeps flogging it.

It boggles my mind how folks stupid enough to do things like that are able to make the money to get neat stuff only to destroy it

As described, that entire engine is basically toast.

I don't blame you a bit, but a review of this supposed "shop" might be nice in the review section of this board.

Btw, a lexus is nothing more than a glorified Toyota...

trash

It seems like Will Rogers said it best''common sense is not as common as most people think. having said that, it dosen't matter what eng. the damage was done not by low oil pressure, dirt in the oil, but by ignorance. too many people feel that they know something no one else knows. that's when the train starts off the track. too much money has been wasted on this project. move on.

i love how ths is a big deal on the local car forum

everyone thinks that the "poor fitting downpipe" is what cause the first turbo to die, apparently a 1/8" wall 1.5 dia SStube has the STRENGTH to flex a CAST IRON turbo housing

that turbine housing is heavy as a brick !!!! its not gonna flex !!!

im sorry, im not gods gift to cars ... i dont know everything, and ALOT of people on this forum can absolutly DWARF me in outright automotive knowledge....

... but i have the common sense to know that the turbo dieing, and the rod bearings dieing ate TOTALY RELATED

-turbos NEED ONE HUNDRED PERCENT of their required oil to live a long life
-rod bearings were beaten to the point that they had a MASSIVE GAP
-oil starts P*****G out the gap
-rest of the engine doesnt get its needed oil
-weakest link dies (turbo)

is this REALY that hard of a concept to follow ?????

to compare this to the human body ..... getting stabbed in your leg can cause you to die ... simple as that

So this buddy is one of those guys who asks questions and advice with his mind already made up and ignores the 999 people who disagree with him and listens to the one in a thousand that agrees with him? I don't blame you for not touching this guy's car again.
