Outer Limits 4x4 Board

ok just fitted a front mountintercooler to 3.0td (1kz-te) and one of the silcone hoses blew off ....

no probs i can fix that but i notice alot of oil inside the pipes , this is the pipes between the turbo and intercooler. is this normal or bad cos before i fitted it i cut the old pipe and no oil was in that one . any idea please??

when you say no oil was it totaly dry or was there a small amount/film of oil, Could be that there was no low point in the piping before and now there is so it will build up insted of being passed through the engine like it normaly would.

yeh thats what im thinking.

Oil catch can would solve your problem, but most factory intercooled turbo diesels dont need a catch can from factory to work.

Oil could be coming from turbo seals, or just blow by.

yeah its a film of oil i would say and its not dry ... its enough to run your finger on and get it dirty . i kinda agree with what you guys are aikn and worried about it being a seal . how does a catch can work and how do you hook it up i have heard of them but dont really know much about them

and wouldn t i notice a difference in performence if i blew a seal

Exactly the same thing happened to my 80 series deisel after turbo and intercooling with a thin film of oil in hoses and intercooler.
I worried about it and talked to everyone I could thinking it was terminal engine probs.
Everyone had a differing opinion on what was causing it, but to make a long story short, I disconnected the blow by hose from the rocker cover which fed back to pre-turbo and ran it into a catch-can (coke bottle!!) and have watched how much it caught.
Too my surprise the "copious" amounts of oil I thought I was loosing turned out to be stuff all over 6 months or more.(it basically made the inside of the coke bottle a bit oily, thats it!!!)
In my opinion oil under pressure from turbo makes a small amount of blow/by seem like heaps when its spread out through some hoses/intercoolers etc.

thats my experience anyway, hope that helps, cheers

thats is just a bit of blow by just do the same and that'll tell you if it's that or not and i'd think if you'd done a seal it would be pouring it in as oil at the turbo is under pressure

Oil like that is normal - ignore it. Turbo's don't use a perfect seal, amount leaked is neglegible.

Degreaser can help intercooler efficiency.

Put a filter on the tappet cover breather (catch can) and see how much oil that turbo sucks out of the motor...u will be amazed.

when you fitted the IC, did you up the boost as well ?

i blocked the wste gate hose and reconnected it after the ic.

it ran 10psi after i installed it ,then i disconnected the waste gate hose and reconnected it after the ic so it does a factory 11psi,
i have a in car boost controller and it stays on 12psi ( or 13 when its a bit colder in the mornings ) but i keep it on 12 all the time .

the boost didnt really drop much ( 1 psi ) so i didnt really bother uppin it heaps. and you gotta get a dpchip to change the fuel in the 1kz cos its all computer crap so i didnt bother cos there $1300 (which i dont have )

never heard of a vehicle with factory boost that high except trucks and of course marine diesel. Would of thought it to be more around 8psi, maybe check the wastegate actuator is free and no blockage in vacuum line. A little crankcase pressure is expected but to much can lean towards worn oil rings but unlikely, they go for ever

yeah i was a bit surprised too , i checked everyhting for that and its all fine and runs 11 psi standard . i had an isuzu mu and that ran 10 psi standard so i dunno ay.
