Some... "advances", like everything in this car, it's one step forward, 2 sideways and 4 back
1) it's not the EGR elbow, i checked with boroscope and it's intact, it also doesn't leak any gas through.
The turbo whooshing sound is in the front of the car, near the air filter, but the IC to valve hose is in good condition, no cracks or tears.
2) I got to test with the turbo boost leak tester, problem is, it doesn't fits, i check your photos Alex (
https://www.ausjeepoffroad.com/forum...&postcount=224) and mine does NOT fit at all as the gauge impacts the fuel filter body and sensor, i had to put the body all the way inside the hose, and even then it it enters angled at the turbo and had to really crank the hose clamp to near minimum to stop it from leaking there
I have no idea how you managed to make yours fit, unless you chopped the hose
In any case, after bruteforcing it and wasting like an hour and half trying to make it fit, the locking tab of the air hose broke, so i have to keep it pressed on the inlet by hand to test.
What we found is that the
outlet hose to resonator had an important leak, the oring did not look bad or hard but i replaced both ends anyway with the idparts kit with ample dow33 application to the oring and pipe, the turbo outlet oring was a red silicone oring which also looked to be in good nick.
That took care of that leak, but after pressurizing to ~10 to 15 psi,
a huge leak sprung on the inlet valve assembly between the plastic hose inlet(where the temp sensor is plugged) and the metal body on the underside
THAT'S where the turbo whooshing sound came out, now i'm researching to see what seal/gasket goes there and in the meantime removed the entire airbox for easy access and to clean it, the inside is caked in hardened dirt. I also found that the intake pipe has two sets of holes covered by a metal micromesh ¿what are those for?, they were completely clogged so i washed everything
I also notice that ONE of the bolts is not the same as the others, the rest are all inverted torx and the one on the right is a regular torx, it also isn't fastened all the way in and has a washer(but the leak is not topside but underside that part) -did not try to fasten yet-, i fear this is another case of point 4 below.
EDIT: found a photo from january where that bolt is not loose and the flange looks flush with the valve
3) the coolant expansion tank bottom is super grimy with deposits, when i change coolant i'll see how can i clean it, ¿do i use rice and bleach?
4)
¿did i also mentioned that i have stripped threads all over the engine bay in my first post?
they destroyed a lot of the threads on the block with bad screws, one of them is the retaining bolt for the metal hose, they put a 6mm inverted torx bolt and destroyed the threads, luckily the bottom part was somewhat ok and we managed to somewhat fix it with a tap(i don't have thread chasers).
The airbox nut thread was also mangled, one of the fuel filter retaining bolts, and one for the egr valve(they put a bolt with an external nut, the bolt is also crooked) -if not more-
5) I also discovered that the fog lamps have been replaced with aftermarket HID bulbs as i found one of the ballast modules zip-tied to the frame(after removing the airbox), with heatshrunk leads going into connectors, the right one is also busted as the land glass broke and they replaced it with some clear thin plastic cut by shears and glued with silicone caulk... the plastic ofc broke easily and allowed water/whatever to go inside....
¿what the stock bulb for the fog lamps?, i have to see if i find an entire replacement for both assemblies, but it's not a priority atm.
